6. Patients receiving Forensic Services (additional detail)

  • 450 (16%) patients in the Census were receiving Forensic Services
  • Patients receiving Forensic Services are mostly males of working age
  • 5 out of 6 forensic patients were either Overweight or Obese as at the Census

Forensic psychiatry is a specialised branch of clinical psychiatry which relates to mentally disordered offenders and others with similar problems. For the purpose of the analysis contained in this section, forensic patients were identified if NHS Boards indicated “yes” to the following Census question: is the patient being managed primarily by forensic services?

There were 450 patients primarily managed by Forensic Services in the 2022 Census. This is a decrease on the 488 patients reported in 2019.

It should be noted that NHS Greater Glasgow & Clyde, NHS Lothian and NHS Tayside contain Forensic Regional Units which provide services to patients from other NHS Boards. NHS Fife also provide a low secure Learning Disability (Forensic) Regional Unit for the treatment of patients from other NHS boards. The State Hospital (a Special NHS Board), provides a National Service (including for Northern Ireland).

Figure 11: Working age males made up 93% of all forensic patients in the 2022 Census, while males in general made up 96%. Psychiatric, Addiction or Learning Disability Inpatient Beds, NHS Scotland, Forensic Patients, 2022 Census

Specialty of Consultant

A total of 370 (82%) patients receiving forensic services were seen by a forensic psychiatrist. There were less than 1% of patients being seen by a consultant whose specialty was Psychiatry of Old Age.

Length of stay in hospital

Patients receiving forensic services tend to have longer average (median) lengths of stay. The average (median) time since admission at the 2022 Census for patients receiving forensic services was around 2 years and 9 months. This compares with non-forensic services patients who had an average (median) admission time of 3 months.

Group Average (median) number of days since admission Approx. number of years / months
Forensic Services Patients 1010 2 years, 9 months
Non-forensic Services Patients 100 3 months

Of the 450 patients receiving forensic services in the 2022 Census, 340 (76%) had been in hospital for over a year. Only 11 (2%) patients had been in hospital for less than two weeks.

Health and Wellbeing

Mental health morbidities

NHS Boards returned diagnosis codes (ICD-10) for any mental health condition for which patients in the 2022 Census had a diagnosis. Of the 450 patients receiving forensic services for whom diagnosis information was returned, 155 (36%) had 2 or more mental health conditions. This compares to 21% for all adult patients.

The most common condition for patients receiving forensic services was schizophrenia, with 270 (60%) of all patients having this condition. This is higher than the 23% reported for the all adult inpatients. Likewise, patients receiving forensic services are much more likely to have a personality disorder: 1 in 4 forensic patients compared to 1 in 10 for all adults.

Figure 12: Certain mental health conditions are more prominent in patients receiving forensic services compared to all adults, for example Schizophrenia (60% compared to 27%) Psychiatric, Addiction or Learning Disability Inpatient Beds, NHS Scotland, Forensic Patients, 2022 Census
60% of forensic patients have a diagnosis of schizophrenia compared to 27% of all adults in census, this was 24% forensic compared to 10% of all adults for personality disorder, 10% forensic compared to 6% of all adults for learning disability, 14% forensic compared to 4% of all adults for drug related, 15% forensic compared to 12% of all adults for Schizotypal & delusional disorders and 1% forensic compared to 23% of all adults for dementia.

All mental health diagnoses are based on ICD-10 codes. Primary and secondary diagnoses included.

Personality disorders and autistic spectrum disorder counts also rely on respective questions on these disorders. Patients may have more than one diagnosis.

Physical health co-morbidities

A total of 194 (43%) patients receiving forensic services had at least one physical health co-morbidity based on the suite of Yes/No physical health questions (see page 27) as at the 2022 Census. This is lower than reported for all adult patients (53%), though forensic patients tend to be younger whhich may account for this difference.

The majority of patients receiving forensic services who had a physical health co-morbidity had only one condition (65%). The most common physical condition for patients receiving forensic services was diabetes, 55 (12%) followed by hypertension (10%).

Figure 13: The majority of patients receiving forensic services with a physical health co-morbidity had one long-term physical condition, while 3% had 4 or more Psychiatric, Addiction or Learning Disability Inpatient Beds, NHS Scotland, Forensic Patients, 2022 Census
25% of forensic patients with a physical health co-morbidity had one long term condition, 6% had two, 3% had three and 3% had 4 or more long term conditions.

Physical Health Check

The majority of patients (94%) receiving forensic services who were admitted within the last year received a general physical examination. 4 in 5 (78%) admitted over one year ago had received an annual physical health check.

Overall in the 2022 Census, a total of 365 (82%) of forensic patients with returned information (6 were missing) received some form of physical health check, slightly lower than the 89% reported for all adult patients.

Lifestyle factors

BMI (Body Mass Index)

BMI (Body Mass Index) was calculated for patients whose height and weight information was returned. Some patients were excluded because height and weight were extreme outliers (<10 forensic patients). A total of 238 (55%) patients receiving forensic services were obese, while 127 (29%) were overweight. This means that 84% of forensic patients are overweight or obese compared to 2 out of 3 for all adult patients (excluding eating disorder wards).

Smoking, alcohol and other substance misuse

This section contains analysis of patients with alcohol dependence and/or substance misuse based on responses for a combination of questions. A minor methodological change was made in 2017 (see Section 7 for further detail).

A total of 139 (31%) forensic patients smoked tobacco in the 12 weeks prior to the Census. This is three percentage points higher than 2019, however it is lower than the 33% reported for all adult patients.

In the 2022 Census, 121 (28%) of forensic patients had a dependence on alcohol or harmfully used alcohol. There were 18 forensic patients with an alcohol related ICD-10 code. The proportion with a dependence on alcohol / harmfully used alcohol is similar to previous years and continues to be higher than for all adult patients (18%).

A total of 152 (35%) of forensic patients had abused substances (excluding alcohol) in the four weeks prior to their admission. There were 61 patients with a drug related ICD-10 code. The proportion who had abused substances (excluding alcohol) is one percentage point lower than 2019 and 16 percentage points higher than all adult patients (19%). The most commonly used substance was cannabis (30% of forensic patients using substances), followed by amphetamines (11%) and heroin (9%).

Self-harm

Information on self-harm was returned for 252 (56%) of forensic patients. Of these, 23 (9%) had self-harmed in the week prior to admission. This is four percentage points lower than 2019. Of those 23 patients, the majority (70%) had self-harmed by non-accidental injury. Patients can self-harm in more than one way.

Suicidal ideation

Information on suicidal ideation was returned for 247 (55%) of forensic patients. Of these, 14 (6%) had expressed suicial ideation on admission to hospital, three percentage points higher than in 2019. This is much lower than that reported for all adult patients (12%).
