Steps

Process

Person specific issues to address

1 .

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Feels tired and short of breath
  • Carers wish to reduce sedation and improve his ability to interact socially
  • Reduce ankle swelling, and falls risk

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • None

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Thiamine: may be redundant if no alcohol intake
  • Bendroflumethiazide: no longer hypertensive. Potential for withdrawal
  • Tramadol: indication unclear (may have been started after surgery)
  • Trazodone or amisulpride: indication unclear. Consider withdrawal if not agitated
  • Antihistamine and emollient: clarify cause of itch i.e. dermatological, CNS problem or ADR. If dermatological problem, consider non-pharmacological measures e.g. attention to washing powder, natural fabrics, etc. as well as regular use of simple emollients in sufficient quantity
  • Antimicrobial cream: should only be used short-term - stop

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Thyroid function: check TFTs and correct hypothyroidism if present
  • Ankle swelling and shortness of breath: consider presence of LVSD. Potentially highly effective treatment available (ACE/ARB, beta blocker) if present. Consider ECG, BNP, ECHO
  • Reduce falls and fracture risk: mainly associated with sedative load; could consider fracture risk modification with osteoporosis prevention (e.g. bisphosphonates). Decision to treat needs to be balanced against expected efficacy (see NNT table) and ability to comply with treatment. Dental health needs to be considered. Unlikely to have time to benefit if life expectancy felt to be less than one year

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Ensure discussion and clear information on which medicines to withhold at times of dehydrating illness
  • Actual ADR: over sedation
  • Risk of CVD events: antipsychotics have increased risk of CVD events in dementia
  • Risk of cognitive deterioration: antipsychotics, antihistamines, tramadol
  • Risk of falls and fractures: antipsychotics, antidepressant, antihistamines
  • Risk of serotonin syndrome: tramadol and trazodone
  • Risk of steroid adverse effects: high dose topical steroid
  • ACB burden score 4 increases risk of falls, confusion
  • Medication Sick Day Guidance: ensure staff have clear information on medicines to withhold if dehydrated (in this case bendroflumethiazide)

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • All medicines are formulary choices
  • Care home advised to dispose of medicines through community pharmacy and advised to only order what is needed

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back
  • Involve the adult where possible. If deemed to lack capacity, discuss with relevant others, e.g. welfare guardian, power of attorney, nearest relative if one exists. Even if adult lacks capacity, adults with Incapacity Act still requires that the adult’s views are sought. Ensure “Adults with Incapacity Documentation” in place

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • Stop:

- bendroflumethiazide

- thiamine

- Fucibet® cream

  • Reduce trazodone and amisulpride to decrease sedation and falls/fracture risk
  • Reduce and review:

- tramadol

- cetirizine

  • Review the need to start bisphosphonate and calcium/vitamin D, taking a person-centred approach

Key concepts in this case

  • Low number of conditions and medicines but still high potential for medicine related harm
  • On-going review of medicine required when commenced for symptomatic relief
  • Apparent low level of multimorbidity, but potential for undiagnosed treatable conditions, e.g. osteoporosis
  • Over sedation a major risk to quality of life, morbidity (falls) and mortality

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Continence
  • Burden of medication
  • Improvement in function where possible

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Levothyroxine: check thyroid function tests to ensure correct dose

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Edoxaban and clopidogrel: no indication for combination. High bleeding risk in combination
  • Alendronic acid: completed eight years treatment. Further years of treatment of questionable benefit. Note CrCl 20ml/min, therefore alendronic acid not appropriate. Cognition/frailty will influence choice of other bone protection
  • Zopiclone: night sedation, long-term use not recommended
  • Mirtazapine: antidepressant with sedative effects
  • Atorvastatin: consider ongoing benefit of high dose statin.

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Consider and discuss how medicines are being managed as with such a large list of medicines, adherence may be difficult
  • Tolterodine: continence major issue therefore review effectiveness and stop if not beneficial
  • Shortness of breath affecting mobility. Consider if uncontrolled heart failure or other treatable cause
  • Consider ongoing therapeutic management of osteoporosis in context of frailty

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • High risk combination of edoxaban and clopidogrel: excessive blood thinning
  • Edoxaban dose too high. Reduce to 30mg as weight less than 61kg. Note reduced renal function and not licensed when CrCl less than 15 ml/min
  • Diabetes:
    • blood glucose control too tight.
    • Hypoglycaemia more likely with gliclazide and could be contributing to episodes of confusion and variable cognitive function.
    • Metformin: low creatinine clearance, therefore not indicated
  • Blood pressure control too tight with postural drop, review perindopril and indapamide. Note perindopril indicated for reno-protection in T2DM
  • Zopiclone and mirtazapine: risk of falls and sedation
  • Levothyroxine without recent TFTs. Check to ensure correct dose
  • Digoxin in presence of excessive bradycardia. Reduce dose and consider checking digoxin levels due to impaired renal function
  • Alendronic acid: not indicated with eGFR less than 35 ml/min
  • Tolterodine: anticholinergic and concern over worsening cognitive function
  • Paracetamol: reduce dose as weight less than 50kg

Medication Sick Day Guidance: advice given for perindopril and gliclazide (if continued)

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • All medicines are formulary choices
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • Stop:
  • alendronic acid
  • clopidogrel
  • metformin
  • perindopril and indapamide. Note before stopping perindopril, ensure symptoms are not due to heart failure. Aggressive treatment of albuminuria outweighed by potential problems with low blood pressure
  • Reduce:
  • Paracetamol to 500mg four times a day
  • Digoxin and check level. Stop if pulse remains less than 65bpm
  • Gliclazide or stop with follow up
  • Atorvastatin or stop to reduce tablet burden
  • Zopiclone. Discuss the risk and benefit of night sedation and option to gradually reduce with an aim to stop
  • Review mirtazapine: check indication and efficacy and withdraw if unclear
  • Review levothyroxine dose: check TFTs
  • Review tolterodine and trial stopping to assess effectiveness
  • Discuss oral calcium/vitamin D supplement and option of alternative formulation
  • After drug holiday, careful consideration needed of risk and benefit of continuing osteoporosis treatment
  • Ask about bowel function as could be affected by medication
  • Referral or signposting for management of low body weight and nutritional needs
  • Complete falls assessment
  • Consider carer stress and support available. Provide detail of local support services

Key concepts in this case

  • Medicine targets need to consider the individual and be appropriate for them, especially in frailty
  • Although most medicines here have a clear indication, many are in the range of overtreatment
  • Marked strain on individual and carer with large tablet burden
  • Increased frailty reduces physiological reserve for dealing with medicine side effects
  • Unfortunately, many conditions that cause serious impairment of the individual’s quality of life require medicines that are associated with severe side effects e.g. continence and night sedation
  • When multiple medications are changed, consider introducing changes sequentially, accounting for what matters to the individual

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Support and encourage independence and interaction where possible
  • Ensure symptoms are well controlled

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • No drugs considered essential

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Gabapentin: indication not clear and may no longer be needed. Risk of sedation and confusion
  • Lisinopril and amlodipine: tight blood pressure control, likely to be over treated. Target BP control should consider comorbidities and frailty using a person-centred approach
  • Gliclazide: tight HbA1c, therefore likely over treated
  • Sertraline: unclear indication, may be possible to withdraw
  • Atorvastatin: likely commenced after possible TIA several years ago, likely limited effect now
  • Lorazepam: unclear indication, may be possible to withdraw
  • Folic acid: may no longer be needed
  • Review indications for all medications in old notes/records

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Recent hip fracture and no investigations recorded for osteoporosis. Consider if life expectancy sufficient for time to benefit from treatment. In this case may be too short. Note: if considering bisphosphonate treatment need to assess dental health
  • Assess pain control. Is paracetamol still needed as regularly as four times a day?

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Risk of hypoglycaemia with tight blood glucose control
  • Risk of falls and increased harm with tight blood pressure control
  • Risk of sedation and increased confusion with gabapentin
  • Risk of sedation and increased falls with lorazepam
  • Medication Sick Day Guidance: ensure staff have clear information on medication to withhold (in this case lisinopril and gliclazide if continuing)

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • All medicines are formulary choices
  • Care home advised to dispose of medicines through community pharmacy and advised to only order what is needed

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • Stop lorazepam
  • Stop gliclazide. Review HbA1c after three months
  • Consider stopping atorvastatin due to limited life expectancy
  • Reduce and stop lisinopril and amlodipine
  • Reduce gabapentin gradually and assess pain control
  • Reduce and stop sertraline, if agreed
  • Change calcium/vitamin D supplement to a once daily preparation
  • Low BMI and history of acute on chronic poor nutrition. Encourage continued focus on nutrition in care home. Look for old weights in notes/records. Assess Malnutrition Universal Screening Tool (MUST) score
  • Potential for improvement in physical and cognition with improved nutrition, encouragement to mobilise and interaction in care home activities.
  • Discuss changes with appointed guardian

Key concepts in this case

  • Transfer to long-term care is an important change of care setting and is a trigger for medication review
  • Frail older adults frequently have a range of conditions with diagnosis often made when younger and fitter. Treatment targets are likely to change with time and caution is needed to prevent over treatment
  • Improvements in function can be made with non-drug interventions especially in adults who have become deconditioned due to illness or social isolation. Consider nutrition as a reversible cause of decline in function
  • Ensure all medications have a valid current indication
  • Sedatives should be avoided especially for long-term use
  • Reduced time in medication administration can free time for other activities for the individual and staff that may be more beneficial
  • Social health is important, and care plan should involve exploration of individual’s interests and enjoyments

  • She feels sick a lot of the time

From talking to care staff:

  • She has no problems swallowing food or drink. She likes paracetamol tablets halved but they stick in her throat. When given large tablets she chews these rather than swallowing them whole. This seems to be due to her dementia rather than due to her swallow
  • Chewing medication seems to make her feel sick, and the number of tablets compounds this
  • She refuses to take medicines a few times each week, or she takes some but not all of them. Staff are going back to try again at each medication round
  • There has been no difference since starting metformin. The nausea seems to be related to the number of medicines
  • Subjectively (the resident can verbalise pain) and objectively (using an observational pain score for people with dementia) the resident is in pain much of the time

Observations, examinations and results

Note: local laboratory reference ranges may vary

Relevant results one month ago:

  • Weight 96kg, Height 154cm, BMI 40.5kg/m2

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Sore itchy legs: improve analgesia
  • Nausea and vomiting due to number and size of tablets

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • No current medication is essential but medicines to relieve symptoms and improve quality of life should be prioritised

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

Review the need for:

  • Omeprazole and metoclopramide recently started for nausea and vomiting
  • Tramadol: not controlling pain but paracetamol often refused due to the size of the tablets
  • Fexofenadine: for itchy sore legs
  • Lorazepam: for stress and distress in the context of dementia
  • Laxatives: for opioid induced constipation, aggravated by poor mobility and diet

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Review pain management
  • Reduce peripheral oedema
  • Improve mood
  • HbA1c to be checked three months after starting metformin

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

Review need for:

  • Metoclopramide: risk of adverse effects e.g. extra-pyramidal
  • Omeprazole: increased risk of electrolyte disturbance
  • Tramadol: increased risk of falls
  • Lorazepam: increased risk of falls, potential to reduce from regular to as required use if less agitated once pain is managed
  • Furosemide: review dose of and its effect on renal function
  • Nausea: consider metformin as probable cause. A switch to MR preparation is not an option as she chews large tablets such as paracetamol and metformin. Option for liquid preparations
  • Medication Sick Day Guidance: ensure staff have clear information on drugs to withhold (in this case prescription of furosemide and metformin) 

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Metformin liquid more expensive than tablets but clinically justified
  • Paracetamol capsules are less expensive than oral suspension, however still large capsules. Once pain is managed, could try capsules, however crunching capsules may cause nausea again
  • Care home advised to dispose of medicines through community pharmacy and advised to only order what is needed

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • The proposed changes to medication were discussed and agreed with her welfare power of attorney
  • Care staff will administer medication, monitor effect and her ability to take medication
  • Stop metoclopramide, omeprazole once nausea resolves
  • Reduce tramadol as regular paracetamol used
  • Reduce lorazepam with aim to withdraw
  • Change paracetamol, and metformin to liquid preparations
  • Review furosemide, dose could reduce if increased mobility improves oedema
  • Review fexofenadine, stop if itch resolves with oedema, or trial without
  • Review laxatives, as mobility improves and tramadol reduced
  • Medication dosing remained four times a day, this could be reviewed once leg pain has been managed to trial reduction in paracetamol frequency

Key concepts in this case

Pain relief in a person with dementia

Relief of itch

  • Non-sedating antihistamines would usually be first line choice in an older person
  • Appropriate use of wound management products and emollients by care staff relieved itch in this case

Tailoring medication formulation to suit the person

  • Although more expensive, the use of liquid formulations of medicines can be clinically justified in some cases

Reduction in potentially inappropriate medication

  • Tramadol can increase risk of falls, drowsiness, constipation. Use was reduced and then stopped by enabling regular use of paracetamol
  • The complex interaction between the resident’s pain, mobility and mood meant that better pain relief improved her mood and her mobility. This in turn meant that lorazepam could be reduced, and the additional furosemide dose was not required (which can increase the likelihood of dehydration or renal impairment, and falls due to lower blood pressure)
  • The total number of medicines prescribed and dosing frequency was reduced, allowing more time for care staff to provide other care
  • As a care home resident, staff can encourage her to adhere to a healthy diet. Her physical activity can be increased since her pain is better controlled

9.5 Case study: Younger adult with intellectual disability in a care home

Case summary

Background (age, sex, occupation, baseline function)

  • 38-year-old female
  • 24-hour care in group care home due to severe intellectual disability

History of presentation/ reason for review

  • Care Programme Approach (CPA) called to discuss deterioration in presentation
  • She had become very drowsy, has recurrent vomiting, increased seizure frequency, intermittent episodes of stupor/unresponsiveness, appears pale and clammy

Current medical history and relevant comorbidities

  • Non-oral: medications and sustenance given via gastrostomy
  • Recurrent aspiration risk (including silent aspiration from secretions)
  • Recurrent chest infections/pneumonia - exacerbates seizures and requires out-of-hours GP contacts
  • Different seizure types – tonic-clonic, tonic, focal, myoclonic, status epilepticus (including non-convulsive status epilepticus (NCSE))
  • Lennox-Gastaut Syndrome (LGS)

Current medication and drug allergies (include over the counter (OTC) preparation, traditional medicines and herbal remedies)

Allergies or adverse drug reactions (ADRs): nil

  • Clobazam 5mg/5ml suspension: 10mg (10mls) at night (regular treatment of seizures)
  • Lamotrigine 100mg dispersible tablets: one tablet twice a day

  • Phenytoin 30mg/5ml solution: 270mg (45mls) once daily at night
  • Rufinamide 200mg/5ml suspension: 200mg (5mls) twice a day
  • Sodium valproate (Epilim®) 200mg/5ml liquid: 1gram (25mls) twice a day

As is common in those with intellectual disability, the medication regime is static, with minimal changes in recent years, other than addition of mirtazapine.

Over the counter medicines: nil

Lifestyle and current function

  • Non-smoker, nil alcohol, diet entirely comprised of enteral feed
  • Has normal periods of alertness and interactivity, reduced when physically unwell or has had a recent seizure

“What matters to me” (ideas, concerns and expectations of treatment)

  • She is non-verbal
  • Elderly father and sister have ongoing contact. They are distressed but also accept that she had been given a limited life expectancy as a child.
  • Fully prepared to take recommendations from the Health and Social Care Team
  • Family feel that antiseizure medications (ASM) are most important, and acknowledge the anxiety caused by the introduction of the Valproate Pregnancy Prevention Programme (“Prevent”) for women of childbearing age

Observations, examinations and results

Note: local laboratory reference ranges may vary

  • Weight 47kg, Height 155cm, BMI 19.6kg/m2
  • Routine bloods are similar to her normal baseline (e.g. elevated LFTs aligned with treatment with sodium valproate and rufinamide, albumin levels within range and no recent changes)
  • Chest clear on auscultation
  • Urinalysis normal

Most recent relevant consultations

  • Two months ago: antidepressant therapy started for signs and symptoms indicative of a depressive episode, with moderate improvement
  • Four weeks ago: Valproate Pregnancy Prevention Programme annual risk assessment form completed by intellectual disability psychiatrist
  • Meeting convened to discuss commencement of palliative care pathway:
    • Discussion with medical team, welfare power of attorney, family and carers around immediate commencement of palliative care, including a decision not to aggressively treat symptoms of physical health, admit to hospital or provide Hospital at Home care
    • Evident from case records that recent ASM therapeutic drug monitoring (TDM) has not taken place with documentation that regular drug monitoring is not indicated. Epilepsy nurse specialist advises that given complicated profile, it would be indicated in this instance
    • Concerns raised about some aspects of the presentation being similar to neurotoxicity and/or non-convulsive status epilepticus
    • Acknowledgement and documentation of medication regime including contra-indications (metoclopramide) and pharmacological agents that are difficult to manage or outwith scope of best practice guidelines (phenytoin for management of LGS)

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Improving quality of life: over sedation potentiates poorer/recurrent physical health issues
  • To review polypharmacy and potential interactions

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • All antiseizure medications (ASM) require specialist input. Rufinamide requires enhanced specialist consideration and referral
  • Legislative requirements met for ongoing use of sodium valproate
  • Changes to non-ASM could destabilise physical health and thus create additional provoking factors for increased seizures

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Mirtazapine – confirm indication. Are there sufficient signs of mood disorder/moderate depression to balance the risk of over-sedation (with clobazam). Consider if signs of low mood caused by frequency of seizures
  • Consider sedation profile

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Seizures and respiratory conditions have known linear connection. Sedation can contribute to overall poorer outcome
  • Assess effectiveness by combination of:
  • Review drug history and consider cautious reduction in overall drug load
  • Review for evidence of neurotoxicity from ASM and consider pharmacokinetic and pharmacodynamic interactions
  • Increase sensory and interactive activities to monitor improved cognitive response

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Risk of inappropriate palliation
  • Risk of over-sedation and worsening of chest health, leading to risk of morbidity/mortality
  • Mirtazapine has the potential to increase seizure frequency
  • ASM TDM to monitor for potential toxicity, then ongoing to monitor variance in levels
  • Note phenytoin has non-linear pharmacokinetics and will need at least 21 days following dose changes to reach steady state again
  • Ongoing consideration of potential for reactive neurotoxicity when prescribing, deprescribing, or alterations of dose
  • Metoclopramide contra-indicated in epilepsy and ADRs may cause misdiagnosis/inappropriate prescribing (see note below)
  • Care staff should be trained in the administration of any rescue medication
  • Staff education on identification of likely symptoms of non-convulsive status epilepticus and neurotoxicity
  • Include pro-forma / symptom checklist to support when to escalate

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Medicines should be prescribed by brand for epilepsy
  • Clear rationale for non-tablet formulation
  • Care staff advised to dispose of medicines through community pharmacy and advised to only order what is needed

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • Phenytoin: implement two weekly serum level check – most unpredictable pharmacokinetic (non-linear) and highly interactive and highly protein bound
  • If changes to medication do not resolve altered consciousness and CT/ MRI alongside blood tests (U&Es, calcium, etc) are clear, consider EEG to exclude neurological basis of deterioration (non-convulsive status epilepticus NCSE)
  • ASM: referral to neurology and joint working with epilepsy and intellectual disability team to rationalise current ASM
  • Use of formal care/support structures (Care Programme Approach) to potentiate inter-professional collaboration and mapping of outcomes
  • Share information to support parents/family/carers e.g. local carers centre, Epilepsy Scotland website, Quarriers fieldworker service (this should have occurred via epilepsy specialist services input).

Outcomes

  • Blood tests showed severe neurotoxic levels of phenytoin 33mg/L (normal range: 10-20mg/L)
  • Phenytoin cautiously reduced in 25mg increments every four weeks and levels returned to baseline

Key concepts in this case

  • Diagnostic overshadowing in people with intellectual disability. This occurs when a health professional makes the assumption that the behaviour of a person with intellectual disability is part of their disability without exploring other factors such as biological determinants
  • People with intellectual disability often remain on medication longer than necessary and are more likely to accrue polypharmacy
  • Long-standing polypharmacy: a changing presentation requires investigation due to various factors that have been subject to change e.g. biophysiology secondary to natural ageing; addition of medication due to age related physical health needs
  • Role for proactive monitoring of blood serum levels in complex clinical scenario
  • Reactive prescribing of anti-emetic added to sedating profile, was potentially pro-epileptic and required treatment of neurotoxicity symptoms

Additional information regarding metoclopramide:

  • People with intellectual disability are more likely to have acute episodes of gastrointestinal distress and are often prescribed short courses of metoclopramide.
  • Metoclopramide adverse effects include movement disorders and extrapyramidal side effects which can complicate differential diagnosis and/or lead to diagnostic overshadowing of stereotypy, subtle epileptogenic activity (i.e. the side effects of metoclopramide may be confused with signs of epilepsy). In individuals with communication deficit, this increases the risk of emergent behaviours or changes of presentation being misdiagnosed or diagnostically overshadowed (i.e. side effects of metoclopramide could be interpreted as normal behaviour in someone with intellectual disability).
  • Metoclopramide is contra-indicated in epilepsy; people with intellectual disability have a 30-33% prevalence rate for epilepsy. This sub-population are more likely to develop late onset or epilepsy of older age due to atypical cerebral structures.
  • All of the above may be underpinned by ongoing or longer than indicated therapy with metoclopramide.

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Secondary prevention of coronary events: likely to derive macrovascular benefit from tight glycaemic control; consider statin and BP control
  • Stroke prevention in AF: CHA2DS2-VASc score 4, consider replacing aspirin with anticoagulant; check rate control
  • COPD management: check symptom control (including exacerbation rate) and inhaler technique. Review ICS (single ICS not licensed in COPD) and/or escalate bronchodilation
  • Pain management: review symptoms, pain score and expectations. If gabapentin prescribed for back pain, then consider withdrawal; review NSAID
  • Depression: review duration of treatment and ongoing need
  • Hypothyroidism: check TFT result
  • CKD: check and monitor for proteinuria
  • Diabetes: HbA1c high despite three antidiabetics; check adherence.
  • Pioglitazone use is cautioned in those with CVD, consider stopping and starting an SGLT-2i

  • Identifying untreated indications (in this case atrial fibrillation)
  • Identifying high risk drug combinations particularly in those on multiple medications
  • Effect of reduced renal function on medication dose, e.g. metformin
  • Link with non-pharmacological management
  • A longer consultation may be required to ensure that there is time to cover any concerns and issues and focus on medication and deprescribe where appropriate, with appropriate follow-up
  • The need for a multidisciplinary approach

“What matters to me” (ideas, concerns and expectations of treatment)

  • Finding multiple medicines challenging to take
  • Supported by daughters but feeling much more isolated since COVID-19 lockdown. Previous social interactions have not restarted and some worries about going out
  • Not walking as far and not feeling as able to walk as far
  • Keen to remain as independent as possible at home
  • Worried over risk of fall after fracture several years ago which occurred the year before husband’s death. He was unwell at the time, and this was very stressful. Both were in hospital concurrently at one point

Observations, examinations and results

Note: local laboratory reference ranges may vary

  • Weight 52kg, Height 160cm, BMI 20kg/m2
  • BP last three readings: 142/63mmHg, 118/45mmHg, 138/56mmHg
  • Urea and electrolytes:
    • Urea 10mmol/L (2.5-7.8mmol/L)

  • Suspected urinary tract infection (UTI) six months ago, presented with confusion and dysuria, and treated empirically with antibiotics

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Reduce falls risk
  • Maintain independence
  • Reduce risk of further cardiovascular events
  • Reduce risk of stroke
  • Simplify medication if possible

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Levothyroxine

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Citalopram check ongoing need
  • No indication for combination of clopidogrel and edoxaban

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Co-codamol 30/500mg high strength. Check pain control adequate and well managed. High dose codeine so consider constipation

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • · drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • High risk combination Clopidogrel not stopped when edoxaban started – increased bleeding risk (also citalopram) Stop clopidogrel
  • Omeprazole may reduce efficacy of clopidogrel – change to lansoprazole 15mg if remaining on clopidogrel
  • Citalopram 30mg is above the recommended dose for over 65s. Risk of QT prolongation at this dose in this group. Reduce dose if ongoing need
  • Variable blood pressure readings. Check postural BP. Consider medication adherence. Watch for potential steep blood pressure drop if adherence improves
  • Consider if blood pressure over treated
  • Edoxaban: creatinine clearance 27ml/min and weight less than 61kg therefore reduce to 30mg
  • Zopiclone is a sedative and increases falls risk. High risk, advise stopping

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • All medicines are formulary choices
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • Stop clopidogrel
  • Stop zopiclone combined with advice on sleep hygiene and normal sleep patterns in older age
  • Reduce edoxaban to 30mg
  • Reduce citalopram to 20mg and consider non-pharmacological options for mood (e.g. restarting social activities) with a view to stopping
  • Change co-codamol to paracetamol regularly with as required codeine, and review pain management
  • Postural blood pressure check and ongoing review of blood pressure
  • Discuss compliance aids including medication charts
  • Weight borderline - discuss whether nutrition adequate and compare with previous weights
  • Signpost to options to increase physical activity
  • Possible episode of delirium recently. Check baseline cognitive function
  • Prompt regarding power of attorney

Key concepts in this case

  • High risk drug combinations. On two blood thinners as a second indication (AF) occurred after the first indication of coronary heart disease. Combination not indicated or needed and is high risk
  • Falls risk from sedatives and tight BP control
  • Effect of renal function on medication dose – edoxaban
  • Adverse effects of social isolation on function
  • Non-pharmacological interventions

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Does not want to stop any medication, reports all are effective despite pain 10/10. “If it’s not broke, don’t fix it”
  • Wants to go out to bingo/shops
  • Challenge of matching her expectations of remaining on all medicines versus reducing risks of ADR/side effects. Suspicious of reviews due to past experiences.
  • Discuss realistic expectations of pain management
  • Discuss non-pharmacological ways of managing pain
  • Develop a therapeutic relationship

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Essential – none

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Nitrofurantoin: complains of UTI despite continuous nitrofurantoin. CrCl 33ml/min, so should be avoided and no evidence to support prophylactic use beyond six months. Trial without
  • Mirtazapine, zopiclone and diazepam: contributing to anticholinergic burden (ACB). Review and rationalise if possible after opioid reduction. Reassess GAD. Not keen to engage with mental health teams currently, has tried before, with no benefit
  • Zopiclone: trial reduction after opioids have been reduced
  • Amlodipine: BP adequately controlled, with no postural drop

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Bone protection: awaiting DXA, receives vitamin D but no calcium, however her diet is calcium rich with full fat milk, cream and cheese

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Quinine sulfate: still reports leg cramps, therefore trial without
  • Oxybutynin: high ACB. She reports previous catheterisation because of urinary retention. Trial discontinuation to reduce ACB, then assess urinary frequency
  • Opioids: she reports 10/10 for pain despite 240mg MED dose.

Discuss ADR and potential harm, increasing risk of falls, hyperalgesia, impact on cognition, sedation, immune suppression, query a factor in recurrent UTIs

  • Plan: reduce oxycodone by 7-10% every two to four weeks to achieve lowest possible dose
  • Paracetamol: Reduce dose to one tablet as weight less than 50kg
  • Reassess BP after medicines are deprescribed with potential to reduce ramipril

Medication Sick Day Guidance given for ramipril

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • Check local formulary choices for sustained-release oxycodone and if necessary, switch to a more cost-effective preparation when a stable dose is reached
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete the post-review PROMs questions after their review

Agreed plan

  • Unwilling to change pain medicines at first but willing to ‘trial’ reduction of therapy at subsequent consultations
  • Gradual changes in medicines discussed and agreed
  • Stop: nitrofurantoin, oxybutynin, quinine sulfate
  • Reduce: opioids, then zopiclone
  • Reduce: paracetamol dose
  • Option to include functional assessment scores before and after medication changes, along with the pain score
  • Refer to community link worker for social prescribing and community support options
  • Attitude to smoking explored and reports reducing her cigarette smoking to less than eight a day

After four months follow-up, she had reduced to 45mg oxycodone (90 MED). Pain still 9/10, but now going out with carer one day a week and visiting shops

Key concepts in this case

  • Reducing medicine related harm compared to person-centredness
  • A person-centred approach is required as individuals often feel medicines are necessary and report no side effects. However, a lack of efficacy and risk of adverse effects must be considered and ensure safety in prescribing.
  • There is a need to build a therapeutic relationship with trust to support and influence change, and to deprescribe medicines
  • The need for subsequent and ongoing reviews to address a stepped and supported approach to trials of reduction and deprescribing, ensuring shared decision-making at every stage

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Reducing risk of falls “I don’t want to be in hospital”
  • “Can I take less tablets? Do I need them all?”

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Essential – levothyroxine, Note: insulin for symptom control, not essential in T2DM

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • FBC and folate in range: stop ferrous fumarate and folic acid
  • Hypertension: BP well controlled, severe frailty, history of falls – stop doxazosin
  • Furosemide: 80mg twice daily for fluid overload, oedema controlled, reduce dose
  • Solifenacin: still incontinent, risk of anticholinergic effects, trial stop
  • Ascorbic acid: no longer indicated and recently omitted with no difference in symptoms – stop

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • T2DM: HbA1c 57– Consider individual treatment in relation to frailty and therapeutic aims. Receives short and long-acting insulin, metformin and GLP-1RA (liraglutide): reduce metformin (renal impairment); discuss with diabetes specialist nurse to review liraglutide, rationalise insulins
  • Analgesia: oxycodone MR used regularly, pregabalin not indicated for cancer pain – started for sciatica, now resolved, trial stopping
  • COPD: poor inspiratory flow and on LTOT. Has both pressurised MDI and dry powder inhaler. Check inhaler technique and if required change Trelegy® to Trimbow® with spacer

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Solifenacin: anticholinergic side effects
  • Metformin: eGFR 44ml/min, therefore, reduce dose
  • Oxycodone MR: side effect constipation (Bristol stool chart 2). Essential for cancer, therefore, optimise therapy and change when required lactulose to regular macrogol sachets
  • Mental health – takes both venlafaxine and mirtazapine - increased risk of serotonin syndrome – under care of mental health team but lost contact, and will follow up for review

Medication Sick Day Guidance given for furosemide and metformin

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Carbocisteine - could be switched to acetylcysteine effervescent tablets which will reduce tablet burden
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete PROMs (questions to prepare for my review) before their review

Agreed plan

  • Stop ascorbic acid, doxazosin, ferrous fumarate, folic acid, pregabalin, solifenacin
  • Reduce furosemide, metformin
  • Change lactulose to macrogols, carbocisteine to acetylcysteine
  • Community pharmacy contacted regarding immediate changes
  • Follow-up with mental health team, diabetes specialist nurses

Key concepts in this case

  • Increasing frailty requiring de-escalation of diabetes and hypertension therapies
  • Opportunity for review of all medication, identifying:

what matters to the individual - reduced medication burden

unnecessary therapies

increased risk of adverse effects

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask patient to complete PROMs (questions to prepare for my review) before their review

  • Reduce number of medicines where possible
  • Provide education on medicines
  • Reduce constipation: education about lifestyle e.g. increased fibre intake, physical activity
  • Referral to local weight management services
  • Long-term out of work – check entitlement to benefits- refer to community link worker

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • No drugs considered essential
  • Amiodarone, apixaban, bisoprolol, spironolactone and bumetanide have valid indications and therefore continue (diuretic could be contributing to constipation)

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Gabapentin, Oxypro®, Shortec® prescribed for chronic back pain with no recent review. He reports pain is no longer an issue but concerned that reducing Oxypro and/or gabapentin may exacerbate pain. Reduce Oxypro and gabapentin dose gradually
  • self-report version of the Leeds Assessment of Neuropathic Symptoms and Signs pain scale (S-LANSS) score = 0 does not suggest he is experiencing neuropathic pain and therefore gabapentin not indicated[318]
  • Ferrous fumarate has been prescribed for several years. Current FBCs normal. Stop iron and repeat FBCs and serum ferritin in three months. If needs to restart, current guidance recommends once daily treatment only
  • Solifenacin prescribed for urinary incontinence five years ago. No benefit perceived. ACB score 3. Complains of constipation and sometimes dry mouth. Stop and review in four weeks.
  • Trelegy – review symptoms and exacerbation rate and consider stepping down to LABA/LAMA

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • BP, AF and T2DM well controlled.
  • T2DM and age over 40 with hypercholesterolemia - atorvastatin indicated
  • Analgesia: add in regular paracetamol to help offset need for Oxypro® and/or gabapentin

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • AF: Risk of gastrointestinal (GI) bleeding with aspirin and apixaban. Indication for aspirin not clear- stop. Continue apixaban for AF as per clinic letters.
  • Apixaban dose checked with creatinine clearance - >60ml/min. Continue current dose and check urea and electrolytes annually
  • Ensure he has regular monitoring scheduled for U&Es for spironolactone
  • Gabapentinoids can increase the risk of respiratory depression (has sleep apnoea). Manufacturers advise dose reduction in those with impaired respiratory function (caution)
  • Ensure TFTs and LFTs and U&Es are being monitored every six months as prescribed amiodarone (hypothyroidism may cause constipation).
  • Medication Sick Day Guidance given for spironolactone and bumetanide. Seek advice from community pharmacy to identify these tablets in the dosette box

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • Consider streamlining inhaler devices so that both are dry powder inhalers
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete PROMs (questions to prepare for my review) before their review

Agreed plan

  • Provided with a list of medication, explaining the indication of each drug
  • Start atorvastatin 20mg daily
  • Stop aspirin, ferrous fumarate, solifenacin
  • Monitoring required:
    • check LFTs and lipids after four weeks
    • FBC and serum ferritin in three months
  • Reduce: Oxypro dose gradually with a view to stop
  • Gabapentin reduction. Initially he did not agree to this. Following discussion about risk of respiratory depression and lack of clinical indication, he agrees to a gradual reduction after opioid has been stopped/reduced in the first instance (individual preference)
  • Constipation should decrease with medication changes, so there may be scope to stop senna
    • Importance of adequate fluid, physical activity and dietary fibre intake reinforced
  • Change salbutamol MDI to salbutamol Accuhaler®
  • Choice of MDS discussed and alternatives explored e.g. prompt chart, but he would like to continue with “dosette box”
  • Inform community pharmacy of changes to medicines
  • Agrees to lifestyle changes and referral to local weight management services
  • Agrees to community link worker referral for advice on benefits

Key concepts in this case

  • Inappropriate prescribing of long-term opioids and gabapentin for chronic pain without review
  • Multifactorial nature of constipation e.g. opioid induced, iron supplements, anticholinergic burden, lack of exercise and dietary fibre
  • High risk drug combinations and managing the risk – inappropriate long-term prescribing of dual antiplatelets, and potential need for gastrointestinal protection
  • Solifenacin was prescribed for urinary incontinence which may have been aggravated by chronic constipation. Solifenacin may have contributed to worsening constipation and in turn added to urinary incontinence symptoms, and hence the individual perceived no benefit from it
  • The challenges of managing medication in an MDS. He had lost ownership and understanding of his medication and health conditions. The case presents the practical issues when medication needs to be changed, and the potential delays. Considering other options such as a prompt chart or downloading the national Polypharmacy app may have negated the need for an MDS in the first instance

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Ask person to complete PROMs (questions to prepare for my review) before their review

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Co-beneldopa for PD

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Pregabalin: review as may aggravate motor symptoms of PD
  • Co-codamol: review as may aggravate non-motor symptoms of PD (constipation) – consider paracetamol alone if needed for pain
  • Sertraline: review mood and continued need. Reduce dose to 50mg if ongoing indication (see Quality Prescribing for Antidepressants guidance)
  • Consider non-pharmacological management of depression

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Suggestions to discuss with PD team include:
  • Review formulation and timings as dispersible tablet may be easier in the morning, as that is when swallowing is most difficult
  • First dose should ideally be on waking, which is before the carers visit at breakfast time
  • Ensure speech and language therapy (SALT) referral for swallowing assessment and advice

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day guidance

  • Ensure discussion and clear information on which medicines to withhold at times of dehydrating illness.
  • Potential for interaction between pregabalin, sertraline, codeine (in co-codamol) and co-beneldopa, increasing sedation. Review ongoing need for the non-PD medication
  • Due to importance of timing of medication, if the person is acutely ill, e.g. vomiting which may affect absorption of medication, seek specialist advice on antiparkinsonian medication dose replacement/alternatives (e.g. transdermal)

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • All medicines are formulary choices
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back
  • Involve the adult where possible. If deemed to lack capacity, discuss with relevant others, e.g. welfare guardian, power of attorney, nearest relative if one exists. Even if adult lacks capacity, adults with Incapacity Act still requires that the adult’s views are sought. Ensure “Adults with Incapacity Documentation” in place

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask person or carer to complete the post-review PROMs questions after their review

Agreed plan

  • If agreed with PD team, change co-beneldopa dispersible to early morning, to be taken on waking. Remaining co-beneldopa to be given at breakfast, lunchtime, teatime and bedtime
  • Ensure timing of medication is specified in dose instructions (for transfer to ECS/KIS)
  • Trial reduction of pregabalin, by 25mg every two weeks and monitor pain and sedation
  • Trial paracetamol alone, in place of co-codamol for chronic pain. Monitor pain and constipation side effects
  • Reduce sertraline to 50mg, and review mood and continued need at next appointment
  • There is an Anticipatory Care Plan in place, the individual wishes to remain at home for as long as possible. Welfare POA arrangements are in place and relevant clinical systems (e.g. KIS) are updated with individual’s wishes
  • Referral to SALT is made to highlight the increased swallowing difficulties

Key concepts in this case

  • The need to involve the person with Parkinson’s disease, their family members, carers and PD specialist team in agreeing a care plan
  • The importance of administering antiparkinsonian medicines at appropriate times and suitable formulations
  • Information regarding medication timings is easily accessible across interfaces of care
  • The potential for adverse effects with antiparkinsonian medicines and discussion of benefit versus risk
  • Discuss advance care planning such as anticipatory care plans and Welfare Power of Attorney provisions and document in relevant clinical systems (e.g. KIS)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Essential medication: Clenil®
  • Folic acid replacement recommended

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Episode of depression, possibly related to loss of employment. Trial of citalopram 20mg daily – ineffective
  • Asthma well controlled

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Moderate depressive episode with worsening signs and symptoms, citalopram ineffective

Management with combination of:

  • Switch antidepressant as no effect at eight weeks of therapeutic dose
  • Psychological intervention (e.g. CBT)
  • Non-medicalised interventions e.g. exercise such as walking
  • Given history of harmful alcohol use when anxiety/insomnia, supportive general discussion re negative impact of alcohol on sleep and mood (and also increases risk of gastrointestinal side effects/GI bleeding with antidepressants)

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Discuss worsening symptoms and possible increasing self-harm/suicide risk. Worsening symptom advice and out of hours telephone numbers (e.g. Breathing Space)
  • Follow up review within two to four weeks, or sooner if considered appropriate
  • Current medicines have low overdose fatality risk
  • Try and ensure continuity of care with the same HCP where possible. Offer in-person appointments rather than telephone-based. Caution re digital exclusion given financial situation
  • Discussion about potential harmful effects of cannabis on mental health (paranoid thoughts, anxiety) and lung health. General sleep hygiene advice given

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Dry powder inhalers are more environmentally sustainable than metered dose inhalers. Once mental health improved consider inhaler device
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete PROMs (questions to prepare for my review) before their review

Agreed plan

  • Switch antidepressants: last dose of citalopram today, start sertraline 50mg daily tomorrow
  • Onset of action: sertraline likely to show effect in two to four weeks, review four to six weeks
  • Safety information: suicide prevention advice, contact telephone numbers
  • Low intensity exercise such as walking may help
  • Friend attending with him is supportive, safety information provided as above
  • Try and ensure continuity of care with the same HCP where possible. Offer in-person appointments rather than telephone-based. Caution re digital exclusion given financial situation
  • Social interventions – link with practice-based welfare advisor for money advice (fuel poverty, food poverty, rent arrears); link with practice-based community link worker to explore options for community supports (e.g. gym pass, walking group, address social isolation)

Key concepts in this case

  • Presenting with worsening symptoms of depression, despite starting antidepressant medication
  • Change of SSRI more appropriate than increase dose (due to flat dose effect of SSRIs)
  • Signs of distress with fleeting suicidal thoughts and socially isolated
  • Has attempted low intensity interventions with limited benefit – may struggle to engage with further online support due to low motivation and feelings of helplessness

  • Requesting diazepam for ongoing sleep problems

Current medical history and relevant comorbidities

  • No mental or physical health comorbidities recorded in notes

Current medication and drug allergies (include over the counter (OTC) preparation, traditional medicines and herbal remedies)

Allergies or adverse drug reactions: nil

  • Currently no prescribed medication. Takes street benzodiazepines.
  • Previously prescribed dihydrocodeine for pain related to injuries from assault (broken ankle). On discharge he received a further two weeks’ supply. He did not attend physiotherapy appointments

Over the counter medicines: Solpadeine Max® (codeine 12.8mg and paracetamol 500mg)

Lifestyle and current function

  • Single, no dependents
  • Lives alone
  • Alcohol – current intake is around 30 units week, has been trying to reduce intake

Observations, examinations and results

Note: local laboratory reference ranges may vary

  • No recent bloods or tests

Most recent relevant consultations

During the consultation:

  • When discussing his sleep routine, he avoids going to bed because he has increased anxiety, with flashbacks and recurring nightmares related to a serious assault last year
  • He states his emotions are “all over the place” making him feel “out of control” and that he has memory problems. He explains the assault has triggered memories of trauma earlier in his life.
  • He confirms that he still experiences some pain from the assault and started to buy OTC co-codamol to help manage this
  • By providing a safe place where his concerns are acknowledged, he discloses taking street benzodiazepines and Solpadeine Max® with alcohol, in increasing doses, which helps block out overwhelming thoughts and feelings. He visits various pharmacies to buy the co-codamol, as some refuse the sale due to the frequency of requests
  • He reports that his mood is low with fleeting thoughts of suicide. However, he confirms he does not have any immediate suicidal plans and protective factors, include his family and friends
  • He becomes more tearful and agitated when discussing polydrug use. He is aware of risks having witnessed a friend’s non-fatal overdose and thought a prescription might reduce the risks with street drugs and OTC medicines

    • avoid buying larger quantities of benzodiazepines to limit the risk of an overdose
    • splitting doses throughout the day to avoid withdrawal symptoms
    • keep a note of how much and how often he takes
  • Opioids: supply take home naloxone kit
  • Benzodiazepines: discuss risk associated with street supply - purity and strength are unknown
  • Alcohol: discuss risk associated with alcohol consumption. AUDIT score of 20 indicates specialist referral required
  • Paracetamol: discuss the possible effects on his liver from co-codamol use above recommended doses for a prolonged period of time
  • He must not drive if he is unfit to do so, because he has taken medication or street drugs

  • Lithium – despite the level being in therapeutic range, it is rising and appears to be higher than required to manage bipolar type 1 disorder (see key concepts below)
  • Interaction with ibuprofen: occasionally buys OTC
  • Interaction with ramipril could influence lithium level. Option to change to other medication e.g. amlodipine
  • Alcohol consumption and lithium combined can impair psychomotor skills – this varies significantly between individuals
  • Dehydration can influence development of lithium toxicity. This can be exacerbated by alcohol
  • Lithium and quinine could both prolong QTc interval. Risk increases in females and increases with age. Consider ECG to assess QTc
  • Medication Sick Day Guidance: ensure clear information provided on medicines to withhold if dehydrated (in this case ramipril)

  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Ask patient to complete PROMs (questions to prepare for my review) before their review

Agreed plan

  • Stop: ibuprofen and quinine sulfate
  • Change: ramipril to amlodipine
  • Individual re-counselled on lithium including signs and symptoms of toxicity and how medication/diet can influence this.
  • Lithium levels (and blood pressure) to be repeated in two weeks and if still elevated, lithium to be reduced by 100-200mg. Individual’s mental state to be monitored at each review – also advised to report any deterioration in mental state
  • Education on importance of presenting National Patient Safety Agency (NPSA) purple lithium warning card to community pharmacy when purchasing any OTC medicines (see key concepts)
  • Advise on the avoidance of dehydration e.g. when drinking alcohol and the importance of drinking other fluids

Key concepts in this case

  • It is important to look at trends in lithium levels rather than individual levels, and how this relates to the person’s mental health. In this case the bipolar disorder was managed adequately at lithium levels around 0.7mmol/L and despite the recent level (0.98mmol/L) being in reference range, the dose may be kept at an unnecessarily high level. This puts them at increased risk of side effects (e.g. fine tremor, drowsiness). Given the length of time her mood has been stabilised, levels lower than 0.7mmol/L could also be considered
  • It generally takes five to seven days for lithium levels to fully adjust. Therefore, levels should be taken after at least five days on any new dosage regimen. In some scenarios (such as a recent overdose) a level earlier than five days may be obtained to establish whether lithium levels are trending upwards or downwards. As there was no urgency in this scenario, two weeks was chosen. Levels should ideally be taken 12 hours post dose (if on twice daily regimen the dose should be delayed allowing for this)
  • Lithium follows linear pharmacokinetics and dose reductions should be made accordingly. Specialist mental health teams should be contacted for advice where required. If any dose reduction is made to lithium, the individual’s mental state should be monitored during this transition period for any deterioration.
  • Individuals should be counselled on lithium including importance of monitoring, signs and symptoms of toxicity and factors that can influence lithium levels.
  • Medication interactions and dehydration are common factors that increase lithium levels.
  • Individuals should be offered the National Patient Safety Agency (NPSA) patient information (or similar). This includes a lithium record booklet and alert card. This card can be a useful prompt to individuals and healthcare professionals supplying or prescribing medications to take into account potential interactions. In this case it might have avoided ibuprofen being purchased in addition to lithium
  • Individuals may require medication combinations which interact with lithium (resulting in higher lithium levels). If so, it is important they are fully aware of the risk and fully understand the signs and symptoms of toxicity, and what to do should these occur. More frequent monitoring could be considered.
  • Several medications can prolong the QTc interval. It is important to identify these (especially in at risk individuals) and discuss any additional risk with therapy, or alternative treatment options where available.
  • Other points to consider as part of a comprehensive polypharmacy review are:

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • None

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Atorvastatin: stop, currently non-essential
  • Donepezil: withhold due to low pulse. Investigate cause; if bradycardia due to donepezil then stop. Refer to psychiatry
  • Aspirin: CT head normal
  • Perindopril: BP tightly controlled, withhold until stable and re-assess. No past medical history of LVSD
  • Solifenacin: started one month ago, no improvement in urinary frequency. Stop as increased risk of anticholinergic adverse effects. Consider mirabegron as has no recorded anticholinergic activity
  • Hydroxyzine: rash now resolved. Stop as can increase risk of anticholinergic adverse effects
  • Risperidone: stop as past medical history of cerebrovascular disease. Risperidone can increase QTc. Treat underlying cause of agitation, use non-pharmacological approach as first line

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Low folate: Folic acid prescribed
  • Low vitamin B12: B12 injection prescribed
  • Constipation: Laxatives prescribed

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Monitor bowels (use bowel chart)
  • Monitor blood pressure
  • Monitor pulse
  • Monitor haemoglobin, MCV, vitamin B12 and folate levels

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • All medicines are formulary choices
  • Ensure appropriate disposal of medicines as per hospital standard operating procedures
  • Advised to dispose of medicines no longer required through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

Delirium:

  • Agreed treatment of underlying medical causes
  • Stop risperidone. Agreed to treat underlying cause of delirium and use non-pharmacological options in the first instance. Review regularly, if no improvement following non-pharmacological management and symptoms causing significant distress to patient, or if threat to patient, carers or others, consider pharmacological options. Refer to local guidance
  • Stop: solifenacin, hydroxyzine, atorvastatin, perindopril, donepezil
  • Start: laxatives; folic acid/vitamin B12
  • Covert administration in place for one week. Review need regularly
  • Aspirin, folic acid and laxatives are currently being given covertly as per agreements within signed policy
  • Worsening cognition and function over past three months: discussion of benefit and risks of cholinesterase inhibitors, if to restart (stopped due to potential cause of bradycardia)

Key concepts in this case

• Acute onset in mental status or new onset confusion? THINK DELIRIUM

• Use TIME bundle:

Triggers: identify potential triggers (e.g. constipation, anticholinergics)

Investigate: record national early warning system (NEWS), screen for infection, take bloods

Manage: document diagnosis of delirium, causes and plan

Engage: engage with patient/family/carers, complete “what matters to me”. If patient does not have capacity to consent to care, complete Adult With Incapacity (AWI) documentation

• Use non-pharmacological options such as environment (e.g. quiet room), verbal and non-verbal escalation techniques

• Anticholinergic medications can cause symptoms such as dry mouth, constipation and urinary retention. Exposure to anticholinergic agents has been linked to impaired cognition and physical decline. They may also be associated with falls, increased mortality and cardiovascular events. The anticholinergic effect of individual medicines varies greatly between individual patients, and the effect of multiple medicines are cumulative

• Covert administration: requires a formal agreement between healthcare professionals and carers (it should only be completed for patients who lack capacity to agree to treatment). See Mental Welfare Commission for Scotland: Covert medication good practice guide. Refer to local policy and procedures. Set a date for review of the continued need for covert administration

• Cholinesterase inhibitors: stopping established treatment may lead to loss of cognition or function, which may not be regained if the medication is restarted. The risks and benefits of deprescribing should be considered carefully

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice
  • Currently functioning at below her normal physical and cognitive baseline, and would like to return to that

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • No drugs considered essential

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Risperidone - added as an inpatient and likely no longer needed, and potentially causing side effects (sedation). When used in delirium, antipsychotics must be at the lowest possible dose for the shortest possible time
  • Oxybutynin - strong anticholinergic, can increase confusion. No clear indication, consider deprescribing
  • Amitriptyline - strong anticholinergic and risk of sedation and increased confusion. If no clear indication, consider deprescribing

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Blood pressure now high. Amlodipine and bendroflumethiazide stopped in hospital. Due to concurrent diabetes consider ACE inhibitor, e.g. ramipril
  • Type 2 diabetes: may be appropriate to consider statin, requires baseline LFTs with monitoring

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Diabetes: HbA1c checked some months ago. Discuss appropriate target level with her when recovered considering age and frailty
  • On several agents that can lead to sedation, cognitive impairment and increased falls risk. Consider need for risperidone, oxybutynin and amitriptyline; and deprescribe where appropriate
  • Antipsychotics (risperidone) associated with increased cardiovascular risk and use. Need to be at lowest possible dose for shortest possible time. Consider deprescribing
  • Consider further investigations if confusion worsens or persists
  • Ensure Medication Sick Day Guidance for metformin and/or ACE inhibitor

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • All medicines are formulary choices
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • Stop oxybutynin and risperidone
  • Reduce amitriptyline
  • Follow up blood pressure, HbA1c
  • Check care needs have been met including adequate fluid and nutrition
  • Refer to local community team for assessment of needs and rehabilitation
  • Medical review if physical and cognitive function not improving

Key concepts in this case

  • Antipsychotic prescribing for delirium needs to be for the lowest possible dose, for the shortest possible time. Adults discharged from hospital on antipsychotics need follow up to ensure they are withdrawn. Clear direction should be provided in the discharge plan
  • If medication is stopped in hospital, a rationale should be included for when to restart
  • Clear indications are needed for all prescribed medications
  • Attention is needed to the overall sedative burden of prescribed medication
  • Hospital discharge is an important trigger for medication review
  • Ensure appropriate local community teams are aware if care or rehabilitation needs are identified
  • Consider undiagnosed health conditions if not improving

9.20 Case study: Antibiotics - penicillin allergy de-labelling

Case summary

Background (age, sex, occupation, baseline function)

  • 85-year-old female, retired office worker who lives alone
  • Usually manages at home with support from family for meals, shopping and housework

History of presentation/reason for review

  • Admitted to hospital after being found by family member on the bathroom floor having fallen overnight
  • Spiking temperatures, complaining of back pain, dysuria, urinary frequency and new urinary incontinence. Has signs and symptoms of heart failure including increasing shortness of breath and ankle swelling
  • Family say she is more confused than usual, resisting help to get into the ambulance, resisting offers of food and fluid
  • Single dose of gentamicin given empirically on the day of admission for a working diagnosis of upper urinary tract infection
    • After receiving the dose, she removed the intravenous cannula and resisted attempts to re-site the cannula, therefore oral treatment considered
  • MSU result showed multiple antibiotic resistance and so treatment with oral penicillin was considered.
  • The nature of penicillin allergy was discussed with the individual and her family. According to GP records and next of kin penicillin “allergy” was nausea and diarrhoea more than 20 years ago during a course of amoxicillin for a chest infection. No reported rash or need for hospitalisation. At the time, she finished the course, and the GP documented the allergy

Current medical history and relevant comorbidities

  • Heart failure with preserved ejection fraction (ECHO within the last year)
  • Mild Alzheimer’s dementia (MMSE 23/30) – 4 years ago
  • COPD – 12 years ago
  • Generalised osteoarthritis – 27 years ago

Current medication and drug allergies (include over the counter (OTC) preparations, traditional and herbal remedies)

Allergies: Penicillin

Current medications:

  • Macrogol 3350 sachets: one sachet twice daily
  • Paracetamol 500mg caplets: two caplets four times daily
  • Salbutamol 200 microgram dry powder inhaler: one inhalation when required for shortness of breath/ wheeze
  • Senna 7.5mg tablets: two tablets at night
  • Trelegy Ellipta® (fluticasone 92 micrograms/ vilanterol 22 micrograms/ umeclidinium 65 micrograms) dry powder inhaler, one inhalation in the morning

Over the counter medicines: nil

Lifestyle and current function

  • The family feel that medication is not being taken regularly, boxes of tablets and inhalers are often found around the house
  • Ex-smoker, 10 pack years, stopped 20 years ago
  • Alcohol occasionally at celebratory events
  • Walks for about a mile most days with a friend or family member
  • Clinical Frailty Score (Rockwood) 5 (living with mild frailty)

“What matters to me” (ideas, concerns, and expectations of treatment)

  • She has always expressed a wish to maintain independence as long as possible. Currently has delirium
  • Family wish to support her at home for as long as possible with a focus for medication on symptom relief

Observations, examinations and results

Note: local laboratory reference ranges may vary

  • Weight 47kg, Height 158cm, BMI 18kg/m2
  • BP 108/56 mmHg, pulse 68bpm regular, oxygen saturation 96% on air, respiration rate normal

    • Sensitive to amoxicillin, gentamicin, aztreonam
    • Resistant to trimethoprim, ciprofloxacin

Creatinine 110micromol/L (60-120micromol/L), Calculated creatinine clearance 25 mL/min

Most recent relevant consultations

  • Recent dietetic advice provided regarding high nutrient density food to encourage weight gain and family have been incorporating that into meals
  • Whilst in hospital:
    • Lisinopril withheld on admission due to low blood pressure
    • Atorvastatin withheld on admission due to lack of indication
  • Furosemide continued due to oedema and increased shortness of breath

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice
  • She wishes to maintain independence as long as possible and return home as soon as able
  • Focus is on symptom relief - breathlessness, pain from osteoarthritis and maintaining cognition

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • As she has a UTI and delirium, antibiotic treatment is essential
  • Donepezil can delay progression to 24-hour care (priority for her)

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Review the continued need for IV antibiotics
  • Lisinopril of limited benefit as preserved ejection fraction so stop
  • She has had fewer than two exacerbations of COPD in the last year - step down to LAMA/ LABA inhaler (Anoro Ellipta®)
  • Discuss need for laxatives: could be used when required

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Judged to be very low probability of immediate penicillin hypersensitivity reaction, and so after discussion with her and next of kin, proceeded to amoxicillin oral challenge
  • Given single dose of oral amoxicillin and monitored at 10, 20, 40 and 60 minutes. Experienced no symptoms of nausea, no rash or lip/tongue tingling or swelling, no tachycardia or hypotension
  • Proceeded to a course of amoxicillin for seven days for a suspected upper UTI. Antibiotics were completed without any adverse effect
  • Monitor breathlessness (also review inhalers)

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Medication Sick Day Guidance for furosemide and lisinopril
  • Donepezil caution in COPD but control is good
  • Paracetamol dose in individual weighing less than 50kg: reduce dose and consider adding ibuprofen gel for painful joints

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • Consider use of oral rather than IV antibiotic (e.g. individual acceptability and sustainability)
  • After assessment by a pharmacy technician, she is struggling to use dry powder devices. She cannot “feel” the dose being taken and therefore orders more inhalers every month, presuming that it is empty. After discussion about how the dry powder device works, she felt more confident she was receiving the required dose.
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • On discharge the GP was informed that the penicillin allergy was de-labelled and her GP records were updated and discussed with family so that they were aware for future episodes
  • Stop lisinopril. Clear note on discharge to GP about reason for this
  • Reduce paracetamol dose to 500mg up to four times a day
  • Change Trelegy® to Anoro Ellipta® device
  • Referred to the GP practice pharmacy technician to assess ways of supporting medicines management at home and remove unnecessary medicines
  • Ensure a written copy of the plan made for future reference by individual, family and carers

Key concepts in this case

  • Penicillin challenge can only be undertaken if there is a clear documented assessment of risk.253
  • There must be careful assessment of the nature of the “allergy” which includes associated symptoms and the timing of the reaction. Explain the purpose of the penicillin challenge to the person. Following successful oral challenge, it is essential to communicate the implications to the individual and family, and to the GP for the allergy label to be removed from medical records
  • Penicillin challenge would ideally be done on an elective basis, through an allergy clinic or similar setting. However, at present such clinics are not available in every area. In practice it may be appropriate to undertake penicillin challenge opportunistically in an acute setting for an individual who is clinically stable253
  • Advice on management of UTI in people over 65 is available[319]
  • Nitrofurantoin is not excreted in urine in renal impairment, and therefore a caution in use if eGFR<45ml/min. Short courses (three to seven days may be considered at eGFR 30- 44ml/min)[320]
  • For older women with low body weight, calculated creatinine clearance is often markedly reduced with only moderately increased serum creatinine
  • Inhaler choice and technique: dry powder inhaler (DPI) versus metered dose inhaler (MDI). Ensure the person understands the action (the lack of feeling of a dose being administered) of the DPI. MDI may be more helpful with a spacer/mask for some people, however there is a need to balance this against the environmental effect. The least sustainable drug is the one that is not taken
  • Inhaled corticosteroid withdrawal in COPD is possible where a person has fewer than two exacerbations per year and no raised eosinophils
  • Differentiating breathlessness from heart failure and COPD. The individual had not been taking furosemide regularly prior to admission and oedema and breathlessness improved when this was taken in hospital

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice

Anticipatory care plan in place includes desire for

  • comfort at the end of life
  • end-of-life care to be in nursing home

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Parkinson’s medicines are essential. Specialist input on replacement for oral formulations. Options include:
  • dispersible medication if easier to swallow
  • nasogastric to deliver medication (unlikely to be useful here due to agitation)
  • switch to rotigotine patches to control distressing PD symptoms and potentially improve swallowing. See notes below
  • Antibiotics can be essential but need to be reviewed regularly

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Majority of medicines should be stopped: amlodipine, aspirin, quinine, simvastatin, thiamine are of no benefit in short-term and should be stopped rather than converted to non-oral forms.
  • Macrogol and senna should be stopped due to diarrhoea

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals
  • Failure to improve with IV antibiotics and fluids in the context of very advanced malignancy, is not unexpected
  • Advanced care directive specified the wish to die at nursing home, and to be comfortable at the end of life
  • Management of agitation and pain control need to be considered

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • IV access and blood monitoring are painful and potentially distressing which needs balancing against benefits and risks such as Staphylococcus aureus bacteraemia (SAB)
  • Oral candidiasis can be caused /worsened by antibiotics
  • Diarrhoea and C. diff infection are risks secondary to antibiotics and exacerbated by laxatives. Stool sample sent to assess for C. diff infection

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Whilst there are associated financial and environmental costs with IV antibiotics and use of vascular devices, there is also “opportunity cost”: IV treatment preparation, administration and monitoring diverts nursing time away from delivering direct care to the individual at end-of-life
  • Care home advised to dispose of medicines no longer required through community pharmacy

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • The individual’s wishes made when they were capable remain the core factor guiding management decisions
  • Adult now lacks capacity and incapacity certificate required
  • Failure to improve on antibiotic treatment should prompt consideration of discontinuation
  • The ongoing benefit of fluids and treatment to lower calcium need to be considered, and whether to stop
  • Consider whether replacement needed for co-beneldopa and involve local Parkinson’s service
  • Stop non-essential medication
  • Pain is a cause of agitation and appropriate pain relief should be considered to address this.
  • Treat oral candidiasis with topical or systemic therapy
  • Consider involving local palliative care service

Key concepts in this case

  • Recognising “end of life” is critical and transitioning care to palliation is often complex and emotive. It is important to keep a clear focus on overall goals when considering the likely efficacy of any intervention balanced by any burdens associated with treatment. This can be difficult in emergency presentations. Discussion of the management of sudden decline should ideally have been discussed previously to avoid adding to distress by requiring difficult decisions to be made in a short time frame
  • Ensure the individual has access to appropriate anticipatory/just in case medications (see Scottish Palliative Care Guidelines)169 N.B. Avoid use of levomepromazine, haloperidol, prochlorperazine, metoclopramide in Parkinson’s disease without specialist advice
  • Focus on symptom control with guidance from specialist palliative care team when required
  • In this case the individual may not achieve their preferred place of death due to management of this decline as a reversible emergency
  • Importance of setting realistic treatment goals before a crisis point
  • Importance of review of efficacy and burden of interventions if commenced
  • Antibiotic prescribing at end of life should be reviewed regularly and only be given or continued if likely to achieve therapeutic objectives specific to the individual (see SAPG good practice recommendations for use of antibiotics towards the end of life)
  • Parkinson’s disease at end of life normally requires specialist input. For example, switching to rotigotine patches from oral formulations. Advice on switching should be obtained from local guidelines and/or OPTIMAL calculator approved by British Geriatric Society and can give advice pending specialist review. Note that rotigotine dose is reduced in adults who are confused or affected by delirium

  • None

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Mirtazapine: clarify date of last review and need for continued therapy. Increased risk of ADRs including sedation and falls
  • Co-codamol: no known indication. Increased risk of ADRs in frailty. Consider paracetamol alone, reducing risk of constipation and need for laxative. If only taking one tablet, subtherapeutic dose of paracetamol

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Prochlorperazine: commenced for treatment of nausea and vomiting only
  • Blood pressure: at target, could reduce ramipril
  • HbA1C: at target, potential to reduce metformin

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Medication Sick Day Guidance followed: dapagliflozin, furosemide, metformin and ramipril temporarily paused during intercurrent illness
  • Macrogol and senna also withheld
  • Reason for temporary suspension of medicines explained and understood by individual and POA

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • All medicines are formulary choices
  • Care home advised to dispose of medicines through community pharmacy and advised to only order what is needed

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • Nursing home staff ensured correct medicines were temporarily withheld
  • Restart: medicines once nausea and vomiting resolved, and the individual is eating and drinking normally for 48 hours
  • Stop: prochlorperazine when acute illness resolved
  • Change: co-codamol tablets to paracetamol tablets
  • Reduce: ramipril to 5mg once daily and metformin to 500mg once daily. Monitor response and adjust accordingly
  • Review: continued need for mirtazapine and laxatives at next consultation

Key concepts in this case

  • Implementation of Medication Sick Day Guidance
  • Fluid intake and output monitoring during potentially dehydrating illness
  • Restarting medicines following sick days according to Medication Sick Day Guidance
  • Review of medicines following acute illness is an opportunity to complete full review of long-term conditions and medicines

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice
  • Reducing risk of falls and associated fractures
  • Provide adequate analgesia

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • No essential drugs

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Check adherence with all therapy as substantial polypharmacy load
  • Osteoporosis: alendronic acid taken for over 10 years, could assess the possibility of a treatment pause for two years given the volume of medication and possible GI side effects. Thereafter review again for most suitable bone protection treatment (e.g. parenteral). Establish whether there has been considerable height loss recently to indicate possibility of vertebral fracture and requirement for spinal imaging
  • AF: warfarin should be reviewed considering falls risk. A DOAC may be a more suitable option and reduce monitoring requirements
  • Hypertension: consider stopping indapamide. May reduce dose of ramipril based on BP target to minimise falls risk. No issues with statin
  • Dyspepsia: may benefit from reduction and withdrawal of lansoprazole, use Peptac® symptomatically. Dyspepsia symptoms may be helped by pausing alendronic acid
  • Continue calcium and vitamin D supplementation, especially as limited time outdoors
  • Review need for zopiclone as this may cause drowsiness the next day, affecting mobility

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Analgesia: use paracetamol regularly for pain rather than when required. Reduce the dose to 500mg four times a day, as weight less than 50kg
  • Ensure chair-based programme of exercises appropriate to need (physiotherapy input) and look at feasibility of weight bearing exercise
  • Review diet with potential for dietitian input

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Risk of bleeds when falling – review warfarin choice for AF
  • Hypertension target may need to be reviewed to reduce risk of falls. Stop indapamide and review. May also be able to reduce or stop ramipril
  • Stop zopiclone as increased risk of sedation and falls risk (phased reduction suggested: reduce to 3.75mg tablets for two weeks then alternate nights for two weeks)
  • Potential for interactions (warfarin, lansoprazole, ramipril) with the herbal remedy devil’s claw as interferes with cytochrome p450 metabolism. Advise to stop taking as no known benefit in OA

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Salbutamol MDI could be changed to a dry powder inhaler (DPI) to streamline devices. She has sufficient inspiratory flow to manage DPI and this reduces environmental impact
  • Diclofenac gel is one of the most polluting pharmaceutical agents and has the potential to interact/interfere with other medication. Discuss continued need or use paracetamol regularly instead
  • Ramipril capsules are more cost-effective than tablets
  • Advised to dispose of medicines through the community pharmacy
  • Advised to only order what is needed, do not stockpile medicines

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • Conduct falls risk assessment (including vision, cognitive function, balance, muscle strength and footwear)
  • Exercise plan and dietitian input to encourage muscle bulk and nutrition
  • Pause alendronic acid for two years. After two years, review risk and potential benefit of bone protection, where IV bisphosphonate or denosumab may be options
  • Change warfarin to a DOAC (refer to local guidance for management of change and formulary choice)
  • Stop indapamide and review BP in four weeks. May subsequently be able to reduce ramipril to 5mg daily, monitor BP
  • Change ramipril tablets to capsules
  • Stop diclofenac gel and take 500mg paracetamol four times a day regularly
  • Phased reduction of zopiclone and advise on sleep hygiene methods and resources
  • Stop Devil’s claw (herbal remedy)
  • Change salbutamol to a DPI (Salbutamol Easyhaler®) for use when needed

Key concepts in this case

  • Reducing falls risk due to medication and other adverse effects
  • Review bisphosphonate treatment duration (risk versus benefit). Benefit of bisphosphonates continues for a period once stopped. After treatment pause (bisphosphonate holiday), review including an assessment of frailty and life expectancy. If benefit still a realistic prospect, consider restarting bisphosphonate. Parenteral bisphosphonate treatment would have less impact with other medication and comorbidities (dyspepsia) or consider denosumab
  • Consider warfarin safety in an individual with falls risk
  • Adherence to therapy with polypharmacy and reducing medication burden where appropriate
  • Highlight the need to review all medication including herbal and OTC medicines
  • Sustainability considerations: diclofenac gel and inhaler choices

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice
  • Pain control
  • Bowel function
  • Burden of medication
  • Improvement in mobility where possible
  • Shortness of breath
  • Current smoker

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Levothyroxine: essential replacement therapy

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Edoxaban: Increased risk of gastrointestinal bleeding in combination with dexamethasone. Consider risks versus benefit of continued anticoagulation for atrial fibrillation in context of metastatic cancer and steroid use.
  • Solifenacin and amitriptyline: two anticholinergic drugs prescribed with cumulative risk of adverse effects. Anticholinergics.
  • Folic acid: Limited benefit in context of advanced malignancy
  • Alogliptin and metformin: Reduced oral intake
  • Diazepam: Indication unclear; falls risk due to concomitant sedatives
  • Dexamethasone: significant impact on blood glucose control
  • Atorvastatin: long-term survival benefit of statin therapy not relevant for patients with prognosis of less than 12 months
  • Lidocaine: Limited comparative data and clinical effectiveness remains unclear. Ensure prescribing in line with palliative care guidelines.
  • Trelegy Ellipta®: Difficulty administering dose; dry powder formulation

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Consider and discuss compliance in context of polypharmacy and mouth discomfort. Can all medicines be swallowed as prescribed?
  • Analgesics: assess effectiveness and tolerability; check requirement of breakthrough doses of morphine
  • Omeprazole: gastroprotection whilst taking dexamethasone
  • Solifenacin/ amitriptyline: Stop if not beneficial, cumulative risk of anticholinergic effects
  • Shortness of breath affecting mobility, may cause anxiety. Check inhaler compliance and assess technique. Alternative devices may be required.
  • Consider ongoing therapeutic management of diabetes in context of reduced oral intake and steroid therapy
  • Monitor bowel function. Adjust laxatives if required, rectal preparations may be necessary
  • Assess oral pain and whether prescribed medications are contributing factors and/or oral thrush evident. Encourage to rinse mouth out with water and brush teeth after using inhaler

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day guidance

  • Bleeding risk increased with edoxaban, dexamethasone and sertraline:
  • Edoxaban: dose reduction required (if continued): 30mg once daily if creatinine clearance 15–50 mL/minute.
  • Diabetes: review blood glucose targets, control potentially too tight, accounting for reduced oral intake
  • Dexamethasone. Monitor for hyperglycaemia. Administer as a single dose in the morning
  • If troublesome symptoms associated with high blood glucose, consider gliclazide or appropriate insulin. Administer once daily in the morning to reduce the risk of nocturnal hypoglycaemia
  • Ramipril: No current hypertension. Long-term renal protective effect not relevant due to limited prognosis. Risk of hyperkalaemia in renal impairment and symptomatic hypotension as general condition declines
  • Diazepam, opioids, amitriptyline and pregabalin: risk of falls, sedation and respiratory depression
  • Morphine: opioid effects increased and prolonged in renal impairment: risk of opioid toxicity
  • Pregabalin: dose reduction required: maximum 300mg daily in 2–3 divided doses if creatinine clearance 30–60mL/minute
  • Solifenacin and amitriptyline: risk of anticholinergic side-effects, complaining of a dry mouth

Medication sick day guidance:

  • Metformin: dehydration increases the risk of lactic acidosis
  • Ramipril: dehydration can impair kidney function

Dexamethasone: ensure aware of steroid sick day guidance and ensure they have a steroid emergency card

6.

Sustainability

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • Stop:
    • alogliptin
    • atorvastatin
    • folic acid
    • metformin
    • ramipril
    • solifenacin (and assess symptoms)
  • Reduce pregabalin dose
  • Reduce edoxaban dose, if continuing
  • Review amitriptyline and trial reducing dose or stopping
  • Review diazepam: consider reducing dose with aim to stop
  • Review lidocaine plasters; trial stoppage and stop if no benefit
  • Dexamethasone: check dosing plan, ensure changes made by specialist team are implemented promptly. Review need for blood glucose monitoring
  • Review laxatives; consider more palatable formulations
  • Consider different inhaler device/ spacer
  • Discuss possibility of changing opioids due to renal impairment and/or swallowing difficulties (e.g. oxycodone or transdermal fentanyl)
  • Check if willing to stop smoking and start nicotine replacement therapy.
  • Referral for management of nutritional needs, if appropriate
  • Consider carer stress and support available. Provide details of local support services

Key concepts in this case

  • Medicine targets need to consider the individual and be appropriate for them, particularly with limited life expectancy
  • Although most medicines included have a clear indication, many are no longer indicated due to limited prognosis
  • Marked strain on individual with significant medicine burden, which may impact compliance
  • Complex blood glucose control due to reduced oral intake and steroid use. Glycaemic targets and antihyperglycemic medicines require review
  • Renal impairment has implications for safe prescribing, including the prescribing of opioids
  • When multiple medications are changed, consider introducing changes sequentially, accounting for what matters to the individual
  • Consider other routes of administration for medications essential for symptom control to reduce tablet burden
  • Access the ECOG performance status scale
  • If regular steroid administration consider requirements during acute illness see (Society for Endocrinology Steroid Sick Day Rules patient information leaflet)[321]

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice
  • Pain control
  • Control of other symptoms such as nausea, constipation, sore mouth, breathlessness and fatigue
  • Struggling to swallow medications
  • Diabetic control
  • Desire for cigarettes

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice):

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Insulin- should not be stopped in those known to have type 1 diabetes
  • Analgesics (fentanyl, morphine, paracetamol, ibuprofen)- assess effectiveness and tolerability of each analgesic, check requirement of breakthrough doses of morphine
  • Metoclopramide- switch to antiemetic with longer half-life that can be given once daily or administer via Continuous Subcutaneous Infusion (CSCI)
  • Omeprazole: gastric protection whilst taking non-steroidal anti-inflammatory drug (NSAID); indicated for oesophagitis.

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs:

  • Antihypertensive - Stop as hypotensive. Low BP is common near the end of life
  • NSAID - indicated for bone pain but patient at risk of gastrointestinal complications, especially if unable to take gastric protectant. Assess risk versus benefit
  • Antidepressant - Stop at a pace he can manage. Fluoxetine has long half-life. Benzodiazepine (e.g. midazolam) may be needed to counteract anxiety/ withdrawal symptoms
  • Oral care - be aware of fluconazole drug interactions but of less relevance near end of life
  • Laxative-stop. Likely to struggle to swallow volume of macrogol laxative in the last days of life due to poor fluid intake. Rectal laxatives can be considered if needed for comfort measures

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives:

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Prescribe as required medicines in anticipation of need for distressing symptoms (analgesic, antiemetic, anxiolytic sedative, anti-secretory). Prescribe subcutaneous (SC) route in addition to any existing oral (PO) route.
  • Consider likelihood of catastrophic haemorrhage; Prescribe anxiolytic sedative by the intramuscular (IM) route in anticipation of need (e.g. midazolam 5mg to 10mg)
  • Switch to a simpler insulin regimen aiming to prevent symptomatic diabetic ketoacidosis (e.g. once daily insulin glargine - Lantus® is often used). Reduce the dose as appetite decreases, seeking advice from diabetic team on a case-by-case basis. Review dose daily
  • If unable to swallow, switch oral medication to subcutaneous administration via a syringe pump (CSCI) if possible. Alternative medications may need to be considered
  • Do not switch opioid patch to alternative opioid/route in a dying patient; continue the fentanyl patch and administer any additional opioid required via CSCI.
  • Ensure breakthrough opioid dose is calculated as 1/6th to 1/10th of total oral morphine daily equivalent. Contact specialist palliative care team for advice if uncertain.
  • Consider benefit of nicotine replacement therapy (NRT) if unable to smoke to avoid effects of nicotine withdrawal
  • Assess need for oxygen therapy if oxygen saturations <88-92%. Manage respiratory distress first line with opioids / benzodiazepines. Oxygen may help alleviate refractory symptoms, or lessen hypoxic related delirium

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for:

Identify adverse drug effects by checking for:

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • drugs used to treat side effects caused by other drugs

Medication Sick Day guidance

  • NSAID - manage the risks and benefits of continuing treatment, particularly if gastric protection cannot be administered
  • Antidepressant - increased risk of bleeding with SSRI/SSNRI
  • PPI - Switch capsules to orodispersible tablets. Alternatively, open capsules and mix the contents with water, fruit juice or sprinkle on soft food
  • Fluconazole - may increase the plasma concentration of all drugs metabolized by CYP3A4 (e.g. fentanyl, midazolam). Review requirement
  • Insulin - preventing distressing symptoms of diabetes is the goal towards the end of life; a range of 6-20mmol/l is generally accepted, although 6-15mmol/l may to necessary to prevent distressing thirst, particularly in younger patients
  • Monitor for signs of gastrointestinal (GI) toxicity (bleeding)

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal
  • Water pollution
  • Prescribe the advised number of ampoules for anticipatory ‘Just in Case’ medicines
  • Utilise the person’s own medication supply wherever possible
  • Advised to dispose of medicines no longer required through the community pharmacy

7.

Person-centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider:

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • Stop: Antidepressant, antihypertensive, fluconazole, laxative, zopiclone, paracetamol (tablet burden)
  • Switch: Symptom focused medications to liquid/ orodispersible formulations or oral to CSCI/SC (SC appropriate for antiemetic and opioid titration).
  • Consider: NSAID can be continued until end of life if helpful for symptom control and benefits are considered to outweigh risks. Seek SPC advice if parenteral NSAID is required
  • Simplify:

Ensure patient and /or family/POA (depending on capacity) understand and agree with goals of care

Communicate that comfort is paramount as patient is nearing end of life

Key concepts in this case

  • Consider appropriate routes of medicines administration if difficulty swallowing. Conversion of essential medications to liquid/orodispersible formulations, subcutaneous (SC) injections or continuous subcutaneous infusion (CSCI) via a syringe pump may be indicated.
  • Prescribe medications for administration via SC route in anticipation of need to ensure that medication is available to treat common symptoms experienced in the last days/weeks of life.314

Opioid for pain relief and/or breathlessness

Midazolam for anxiety or agitation or breathlessness

Levomepromazine for nausea and vomiting or agitation

Hyoscine butylbromide for thin, upper respiratory secretions

  • Consider non-drug measures for symptom management (e.g. radiotherapy, positioning)
  • Insulin should not be stopped in patients with type 1 diabetes. Consider switching to a once daily regime. Minimise interventions and monitoring. Goal is to avoid symptomatic hypoglycaemia or hyperglycaemia/ketoacidosis.[322]
  • Do not switch fentanyl patch to another opioid in a dying patient. Continue the opioid patch and use an additional opioid as required via CSCI.169
  • Risk/benefit decisions may alter as patient approaches end of life. The benefit associated with greater comfort often outweighs the potential harm from adverse drug effects. Decisions should be made in partnership with individual / power of attorney (POA).
  • Consider nicotine withdrawal as a potential cause of delirium, terminal restlessness, anxiety, insomnia, irritability. Offer nicotine replacement therapy if a heavy smoker is unable to smoke.
  • The use of medicines outwith a manufacturer’s licence or ‘off label use’ is common practice in palliative care, for example administration by the SC route, but carries additional responsibilities for prescribers, pharmacists and nurses. Once medications are mixed in a syringe for CSCI administration they become “unlicensed” however, this is considered safe and routine practice provided compatibilities and diluents are checked prior to prescription/administration.315

9.26 Case study: Drug dependency and requests for medication out of hours

Case summary

Background (age, sex, occupation, baseline function)

  • 38-year-old female
  • Part-time shop assistant

History of presentation/reason for review

  • Contact to out of hours (via NHS 24) on Friday evening. Reports increasing pain, described as ‘tingling and shooting pain down my legs which comes and goes.’ Pain is chronic, more than three years, has not changed in nature, just intensity. No other symptoms which might suggest cord compression or other red flags
  • Requesting more gabapentin and tramadol as states that pain is not controlled with current doses, so takes more than prescribed and has run out of medication

Current medical history and relevant comorbidities

  • Depression – 7 years ago
  • Chronic pain: hip and back – 9 years ago
  • Drug dependency – 18 years ago

Current medication and drug allergies (include over the counter (OTC) preparations, traditional medicines and herbal remedies)

Allergies or adverse drug reactions: nil

Currently prescribed:

  • Amitriptyline 50mg tablets: two tablets daily
  • Bisacodyl 5mg tablets: one or two at night as required
  • Co-codamol 30/500mg tablets: two tablets four times daily
  • Gabapentin 300mg capsules: one capsule three times daily
  • Methadone 1mg/ml oral solution: 30ml daily, twice weekly pick-up
  • Pregabalin 150mg capsules: one capsule twice daily
  • Sertraline 100mg tablets: one tablet daily
  • Tramadol 50mg capsules: one capsule three times daily

Over the counter medicines: nil

Lifestyle and current function

  • Single, two grown up daughters who live away from home
  • Moved to the area ten months ago due to violent break-up with previous partner
  • Alcohol: one bottle of wine most evenings
  • Smoker: 30g tobacco weekly
  • Occasional street drug use: cannabis at the weekend
  • Usually little physical activity. Currently unable to drive, as licence confiscated due to drink-driving, so walking to and from work

“What matters to me” (ideas, concerns, and expectations of treatment)

  • Wants to get pain under control
  • Frustrated at time taken to get through on phone to have query dealt with by out of hours (OOH)

Observations, examinations and results

Note: local laboratory reference ranges may vary

  • Urea and electrolytes normal
  • Weight 79kg, Height 168cm, BMI 28kg/m2
  • No change to bladder or bowel function, no loss of sensation
  • Normal MRI scan within the last six months
  • No additional information on Emergency Care Summary (ECS)

Most recent relevant consultations

Has frequent contacts with GP practice and out of hours as runs out of medication, which is dispensed weekly, often due to hip and low back pain.

Steps

Process

Person specific issues to address

1.

Aims

What matters to the individual about their condition(s)?

Review diagnoses and consider:

  • Therapeutic objectives of drug therapy
  • Management of existing health problems
  • Prevention of future health issues, including lifestyle advice
  • Wishes to manage her pain
  • Wishes to reduce her need for out of hours contacts and find ways to better manage her condition

2.

Need

Identify essential drug therapy

Identify essential drugs (not to be stopped without specialist advice)

  • Drugs that have essential replacement functions (e.g. levothyroxine)
  • Drugs to prevent rapid symptomatic decline (e.g. drugs for Parkinson’s disease, heart failure)
  • Methadone maintenance is essential as substance dependence therapy and should not be stopped abruptly. Methadone is normally initiated by specialist services and the risks of prescribing in OOH services is high. Individuals presenting with opioid withdrawal symptoms during the OOH period should be signposted to the emergency department for assessment and management of their symptoms. Consider elimination half-life of medication requested (see below) and risk of harm from prescribing without access to daytime medical records
  • If prescribing, prescribe the smallest quantity needed to allow follow up in daytime GP services and clearly document in case records the strength and quantity supplied

3.

Does the individual take unnecessary drug therapy?

Identify and review the continued need for drugs

  • Multiple medications prescribed for pain, all associated with a risk of dependency and which would require support to withdraw safely in daytime practice:
  • Amitriptyline
  • Co-codamol
  • Gabapentin
  • Pregabalin
  • Tramadol

4.

Effectiveness

Are therapeutic objectives being achieved?

Identify the need for adding/intensifying drug therapy to achieve therapeutic objectives

  • to achieve symptom control
  • to achieve biochemical/clinical targets
  • to prevent disease progression/exacerbation
  • is there a more appropriate medication to achieve goals?
  • Be aware of any local or national policies around prescribing of medicines with risk of dependency during the OOH period
  • Take a person-centred approach to management and prescription request in OOH services. Review any management advice on case records/ ECS from daytime GP and discuss the benefits, risks and alternatives to prescribing. Where prescribing in the OOH period, use the smallest quantity to allow daytime GP practice follow up and document clearly in records
  • During daytime follow up discuss effective pain management options for chronic pain considering physical function, mental health, social and emotional factors. Record clear instructions on patients ECS with indication for use and management of prescription requests during the OOH period
  • Tolerance to opioids occurs therefore higher doses are required to maintain the same level of pain relief
  • Good practice not to combine opioids
  • During daytime follow up target tramadol first for gradual reduction
  • Work with individual to develop a plan to gradually deprescribe gabapentinoids (gabapentin and pregabalin separately) and opioids (tramadol first, then codeine in co-codamol). Agree a plan to communicate to OOH services using ECS
  • Explain potential for withdrawal symptoms and that the tapering may take months. Leave clear instructions for OOH management and prescription requests during this time ensuring safety across transitions of care

5.

Safety

Does the individual have or is at risk of ADR/ side effects?

Does the person know what to do if they’re ill?

Identify individual safety risks by checking for

Identify adverse drug effects by checking for

  • specific symptoms/laboratory markers (e.g. hypokalaemia)
  • cumulative adverse drug effects (see ADR table)
  • · drugs used to treat side effects caused by other drugs

Medication Sick Day Guidance

  • Constipation possibly a side effect of opioid use
  • Increased risk of adverse effects such as drowsiness, respiratory depression and interactions with multiple opioids and gabapentinoids (see MHRA alert)
  • Ensure awareness of need for contraception to reduce teratogenic effects with gabapentin
  • Potentially increased risk of drug-related death due to use of multiple opioids, gabapentinoids and street drugs

6.

Sustainability

Is drug therapy cost-effective and environmentally sustainable?

Identify unnecessarily costly drug therapy by

  • considering more cost-effective alternatives, formulary choices, safety, convenience

Consider the environmental impact of

  • Inhaler use
  • Single use plastics
  • Medicines waste
    • over-ordering
    • disposal

Water pollution

  • During daytime practice review, consider reducing ineffective pain medication and introducing non-pharmacological therapy such as physiotherapy, yoga, CBT. Support may be available from a community link worker to identify the best plan for the individual

7.

Person- centredness

Is the person willing and able to take drug therapy as intended?

Does the person understand the outcomes of the review?

  • Consider Teach back

Ensure drug therapy changes are tailored to individual’s preferences. Consider

  • is the medication in a form they can take?
  • is the dosing schedule convenient?
  • what assistance is needed?
  • are they able to take medicines as intended?

Agree and communicate plan

  • discuss and agree with the individual/carer/welfare proxy therapeutic objectives and treatment priorities
  • include lifestyle and holistic management goals
  • inform relevant health and social care providers of changes in treatments across the transitions of care

Agreed plan

  • In OOH establish what pain medication is requested and take a person-centred, risk/ benefit approach to management in line with local and national policies, until reopening of daytime GP services
  • Recommend follow up with regular GP practice in a suitable time frame
  • In daytime practice recommend stepwise reduction plan for any ineffective medicines in agreement with the individual. Record indication for medicine, any reduction plans and management options for prescription requests during the OOH period on the individual’s ECS
  • Consider option of physiotherapist and community link worker support
  • Signpost to National Wellbeing Hub
  • Alcohol: discussed the effects of alcohol and potential to worsen symptoms related to pain and depression and signpost to local support if available
  • Smoking: recommend smoking cessation services and reduction/cessation of cannabis

Key concepts in this case

  • Managing regular requests (including out of hours) for pain medication which has potential for abuse
  • Special notes around indication for prescribing, planned reduction regimes or suggested management options for early prescription requests can be recorded within the ECS to aid decision making in OOH services
  • In daytime GP practice recommend a plan for reducing inappropriate polypharmacy in pain and depression associated with drug dependency and substance use. This is preferable in daytime GP services due to access to full medical records and relational continuity, as this process can be complex and take time. With a clear plan documented on ECS, this will aid other healthcare providers such as out of hours or community pharmacies
  • Referral to community link workers and third sector agencies may be helpful to assist a holistic approach to the management of pain and depression with a background of substance use. Gaining acceptance and motivation for this pathway may be challenging
  • Varied half-lives for medication (and therefore elimination rates) (see Table 30 below) can be used to help determine if withdrawal effects are likely to be present during the out of hours period

9.27 Case studies: Addressing the use of psychoactive medication for people living with dementia through non-pharmacological techniques

Background

The 2017 Care Inspectorate report My Life, My Care Home highlights the standards

set out in the Scottish Government’s Standards of Care for People with Dementia in

Scotland (2011). It states that for people with dementia, if symptoms develop which cause distress or lead to behaviour that challenges, there should be an integrated assessment to establish the cause and a care plan developed.

A range of non-pharmacological interventions are available including evidence-based therapies, such as group based or individual cognitive stimulation, individual reality orientation therapy, art therapy, therapeutic activities and physical exercise.

Non-pharmacological interventions should be used first line to reduce the need for “as required” medication. When psychoactive medication is prescribed for people with dementia the prescriber needs to be satisfied that there is no reasonable alternative. The medication must be reviewed regularly and a plan recorded to make carers and staff aware of any potential side effects and how to report any concerns.

Case studies

HC-One (care home provider) and the Care Inspectorate worked together on a project in eight HC-One Scotland care homes aimed at improving dementia care and reducing the need for psychoactive medication for people living with dementia.

Staff were trained in “finding the why” for stress and distress behaviours and making adaptions to the physical and social environment. In addition, local system changes were tested to improve appropriate prescribing and use of sedating psychoactive medicines.

The project allowed frontline care staff the psychological freedom to test change ideas and data gathered locally was used to drive improvement. The case studies demonstrate change at an individual level and collectively across a care home.

Case Study 1:

Background: A female resident in a care home was struggling to accept twice daily personal care, with a baseline average of two sessions of personal care accepted per week. Desensitising the resident to the bathroom where personal care took place had limited effect. The service tried consistent staff, which had some effect, but gender of care staff had no effect. However, staff identified that height of care staff was a trigger factor for this person.

Change implemented: Staff of similar height to reduce anxiety

Outcomes:

  • improved personal care - around 10-12 personal care sessions per week
  • a successful reduction (over 50%) of antipsychotic (quetiapine) medication
  • resident has also gained 2.25kg, has a Malnutrition Universal Screening Tool (MUST) score of 0 and healthy body mass index (BMI), with staff reporting she now sits and enjoys her meal in the dining room, something she would not do before
  • reduced staff time dealing with the administrative and challenging effects of the behaviours
Chart 11: Number of personal care sessions per week
Chart showing impact of introducing the change to using smaller staff on the number of personal care sessions per week. An increase is seen after the introduction of the change (which allowed improved care of the individual).

Case Study 2:

Background: One staff member identified a resident watching care staff leave through the glass front door as a key trigger for the resident’s stress and distress behaviour.

Change implemented: a frosted covering was applied to the door

Outcomes:

  • less stress and distress for the resident
  • 60% reduction in use of when required anxiolytics
  • weight gain of 1.4kg and now has a MUST score of 0 and healthy BMI
  • care staff noted less time dealing with effects of behaviours that challenge, including filling in ABC (Antecedent, Behaviour, Consequence) charts and seeking input from external healthcare professionals.
Chart 12: Frosted glass door covering reducing stress and distress
Chart showing impact of introducing a frosted door covering to levels of stress and distress compared to a baseline median. A decrease in distress levels is seen after the introduction of the change.

Case Study 3:

Background: A resident nearing end of life was prescribed and received regular, and when required, psychoactive medicines.

Change implemented: to make her feel safe and reduce her stress, care staff adapted her room to provide a familiar space resembling her own living room, including familiar pictures, throws and cushions. They also purchased a reed diffuser to provide the comforting smell of her husband’s aftershave.

Outcomes:

  • the resident was more settled, and her psychoactive medicines were discontinued
  • a relative of the resident said: “Mum passed away peacefully, not on any sedative medication. She was able to hold a conversation with us and share memories. I will never be able to thank the staff enough for never giving up and giving my mum a nice death.”
  • seeing the outcomes for this resident, staff created a cosy lounge area with a kitchen area and free access to outside space. This allowed a space away from the main lounge that residents could go to if they wanted somewhere quieter
  • a reduction across the unit of when required psychoactive medication by 89%
Chart 13: Changes to room and unit environment reducing use of PRN psychoactive medicines
Chart showing impact of introducing changes to room and unit environment in the use of when required psychoactive medicines. Decreases of medication use are shown following both interventions.

Case Study 4:

Background: The resident initially presented with symptoms that suggested end-of-life. Dementia Care Team determined to ‘find the why’ of the behaviours of distress which increased during sunset, with possible hallucinations caused by shadows in their room. The resident also felt threatened by people following them or sitting outside their room.

Change implemented:

  • as believed to be at end-of-life regular antipsychotic doses reduced and stopped
  • a blind was fitted to the person’s room to reduce shadows and therefore hallucinations
  • a door alarm linked to the nurse call system was implemented so that the person could have private time in their room
  • an activity plan tailored to the resident’s interest (gardening) started

Outcomes:

  • environmental measures resulted in a reduction in stress and distress incidents
  • sedating psychoactive medicines were withdrawn and the resident re-engaged with the environment. However stress and distress increased to a level that the resident was served notice to leave the home
  • psychoactive medicines were re-started but at a lower dose to allow resident to remain in the home
  • the resident now runs a gardening club in the care home, are now mobilising and independent with personal care and eating
Chart 14: “Finding the Why” of stress and distress behaviours
Chart showing impact of introducing a series of interventions in the number of when required quetiapine doses. Chart shows overall trend of reduction in medication doses.

Case Study 5:

Background: A resident was admitted to a care home with an expectation from social work that the placement would fail due to her ‘behaviours of concern’, with long-term hospital care the next stage. The staff recognised there was no activity provided for the resident in order to provide a meaningful day.

Change implemented:

They found things she liked to do and included these in tailored activity plans, along with opportunities for independent activity through ‘life stations’. A life station is an area designed to evoke familiarity and comfort for residents with dementia. These stations reflect aspects of their past life, such as hobbies, careers, or routines. This included her supporting staff with folding towels and matching socks, organising the dressing table life station and supporting the wellbeing staff to set up activity trolleys, dining tables and organise cupboards throughout the day.

Outcomes:

  • a complete reduction in stress and distress incidents
  • no use of when required anxiolytic use in the last four months of the project, and a 25% reduction in the regular risperidone dose
  • the placement in the home was a success
  • the staff approach of “It’s never too late, you must always seek the whygave this resident the opportunity to live their dementia journey in a homely environment.

Case Study 6:

Background: One home worked closely with their GP to agree a process for re-starting (post COVID) three monthly reviews of psychoactive medicines. 11 residents were prescribed psychoactive medications at the start of the project.

Change implemented:

GP reviews and staff training (from the dementia care team) with regular reviews

Outcomes:

  • Eight now had a psychoactive medication review by the end of project:
    • five have an active reduction plan in place
    • two have had risperidone discontinued
    • one had lorazepam discontinued
  • an overall reduction in the level of when required psychoactive medicines used
  • Note: The increase in use of psychoactive medication later in the project was driven primarily by staff who were less familiar with residents, using medicines as a first line option for management of stress and distress
  • therefore, further change implemented when using staff who were unfamiliar with residents, the home’s approach to medication use was shared at the daily flash meetings
Chart 15: When required psychoactive medication use
Chart showing impact of interventions of reintroducing three monthly GP reviews and delivering staff training ion the use of when required psychoactive medication use. Trend shows a decrease from baseline median following introduction of reviews and initially following staff training. Latterly an increase was attributed to agency staff being less familiar with residents.

Case Study 7:

Background: A home recognised that current reviews by prescribers were ineffective because staff did not have the relevant information to hand when clinical discussions took place.

Change implemented:

Staff develop a form containing the necessary information pre-review, such as how often when required medicines are used, the number of distress incidents, resident presentation etc, to make reviews meaningful. The form was developed using a quality improvement approach of rapid change cycles, with different staff members inputting at each cycle.

Outcomes:

  • by the end of the project the home were on version four of the form
  • five residents have had a review with reduction plan in place, and two residents have had psychoactive medication discontinued.
  • feedback on the form was positive:
    • “As a new nurse this form gave me the confidence that I could have the discussion to reduce medication, prompted me to have all the information I needed ahead of time, ready to present and discuss with the prescribing practitioner”. (Staff Nurse)
    • “It encouraged the process and benefit is not using medication.” (Consultant Psychiatrist)
  • A relative of one of the residents noted the benefits of reduced use of medicine. “My wife has had her risperidone and trazodone medication stopped since moving into the care home and staff working closely with her. I feel my wife has a better quality of life and she is now able to understand some of what is being said and is now managing to do things for herself that she couldn’t do before when at home.”

Case Study 8:

Background: A couple of homes wanted to tackle the issue of staff using when required psychoactive medication as a first approach rather than a last resort for behaviours that challenge. A psychological safe space was essential so staff could be honest about administration practices and ways to change this without fear of judgement.

Change implemented:

The homes tested implementing ABC charts with peer review to show what steps were tried before administration of ‘when required’ psychoactive medication. Training and support were given to staff, so they knew what to document on the charts, how to review behaviours, “find the why” and implement strategies to support residents rather than use psychoactive medicines. The idea of the peer review was in case a second person could suggest anything that hadn’t been tried. This gave staff the confidence that when medication was felt necessary that they had explored all non-pharmacological interventions and could evidence as such.

Outcomes:

  • the results in both homes were a reduction in when required psychoactive medication use (Chart 16 and Chart 17).
  • in the first home (Chart 16) the change idea was tested on one resident:
    • when required quetiapine being discontinued, along with a reduction in regular risperidone
    • reduction in falls and better quality of life during their last three months
  • in the second home (Chart 17) there was a 65% reduction in ‘when required’ psychoactive medication administration. This included a period of disruption caused by opening up/merging of units in the home.
Chart 16: Reduction in resident when required quetiapine
Chart showing impact of introducing the use of peer review and ABC charts for when required medication. A reduction in regular risperidone and stoppage of when required quetiapine is shown following the intervention.
Chart 17: Reduction in whole unit when required psychoactive medication
Chart showing impact of introducing the use of peer review and ABC charts for when required medication given across a whole unit. A reduction in when required medication is shown following the intervention. A later increase is attributed to disruption following merging units, followed by a further decrease.
