A Comparison of English and Dutch Long-Stay Patients in Forensic Psychiatric Care

Factors influencing the length of stay in forensic psychiatric settings: a systematic review

BACKGROUND

Forensic psychiatry is often associated with long admissions and has a high cost of care. There is little known about factors influencing length of stay (LOS), and no previous systematic review has synthesised the available data. This paper aims to identify factors influencing the LOS in forensic psychiatry hospitals to inform care and interventions that may reduce the length of admissions.

METHODOLOGY

A systematic review was conducted by searching major databases, including PubMed, EMBASE and PsycInfo, from inception until May 2022. Observational studies conducted in forensic hospitals that examined associations between variables of interest and LOS were included. Following data extraction, the Newcastle‒Ottawa Scale was used for quality appraisal. No meta-analysis was conducted due to heterogeneity of information; a quantitative measure to assess the strength of evidence was developed and reported.

RESULTS

A total of 28 studies met the inclusion criteria out of 1606 citations. A detailed quantitative synthesis was performed using robust criteria. Having committed homicide/attempted homicide, a criminal legal status with restrictions, and a diagnosis of schizophrenia-spectrum disorders were all associated with longer LOS. Higher Global Assessment of Functioning (GAF) scores were associated with a shorter LOS.

CONCLUSION

High-quality research examining factors associated with LOS in forensic psychiatry is lacking, and studies are heterogeneous. No modifiable characteristics were identified, and thus, practice recommendations were not made. There is an increasing necessity to understand the factors associated with longer admissions to inform care and increase success in reintegration and rehabilitation. This paper provides recommendations for future research.

Duration of forensic psychiatric care and subsequent criminal recidivism in individuals sentenced in Sweden between 2009 and 2019

Background

The duration of forensic psychiatric care is in Sweden not determined at the time of sentencing; instead, offenders are regularly evaluated, often with regard to risk of criminal recidivism. The length and justifiability of such a sanction have been greatly debated; however, previous estimates of treatment duration based on datasets delimited to discharged patients—have provided an uncertain groundwork for these deliberations. The aim of this study was to use a more suitable approach to calculate average duration of forensic psychiatric care and to examine the relationship between length of treatment and subsequent recidivism after discharge.

Methods

This retrospective cohort study focused on offenders sentenced to forensic psychiatric care in Sweden between 2009 and 2019 and registered in the Swedish National Forensic Psychiatric Register (n = 2064), with a follow-up period until May 2020. We used Kaplan–Meier estimator to calculate and visualize treatment duration including analyses comparing levels of relevant variables, and then evaluated criminal recidivism in patients discharged from treatment between 2009 and 2019 (n = 640), after stratification for the same variables and dichotomization by treatment duration.

Results

The median duration of forensic psychiatric care was estimated to 89.7 months (95% CI 83.2–95.8). Treatment was longer in offenders who committed violent crimes, suffered from psychosis, or had a history of substance use disorder, and in offenders whose sentences included special court supervision. The cumulative incidence of recidivism in patients discharged from treatment was estimated to 13.5% at 12 months (95% CI 10.6–16.2) and 19.5% at 24 months (95% CI 16.0–22.8). Corresponding cumulative incidence of violent crime post discharge was 6.3% at 12 months (95% CI 4.3–8.3) and 9.9% at 24 months (95% CI 7.3–12.4). Among other findings, in patients without a history of substance use disorder and patients whose sentences did not include special court supervision, recidivism was significantly higher in those with a shorter treatment duration.

Conclusion

Using the entirety of a suitable, contemporary, prospectively enrolled cohort of mentally ill offenders, we were able to estimate—with greater accuracy than previous studies—the average duration of Swedish forensic psychiatric care and rate of subsequent criminal recidivism.

A systematic review of in-patient psychiatric care for people with intellectual disabilities and/or autism: effectiveness, patient safety and experience

BACKGROUND

An increasing number of children, adolescents and adults with intellectual disabilities and/or autism are being admitted to general psychiatric wards and cared for by general psychiatrists.

AIMS

The aim of this systematic review was to consider the likely effectiveness of in-patient treatment for this population, and compare and contrast differing models of in-patient care.

METHOD

A systematic search was completed to identify papers where authors had reported data about the effectiveness of in-patient admissions with reference to one of three domains: treatment effect (e.g. length of stay, clinical outcome, readmission), patient safety (e.g. restrictive practices) and patient experience (e.g. patient or family satisfaction). Where possible, outcomes associated with admission were considered further within the context of differing models of in-patient care (e.g. specialist in-patient services versus general mental health in-patient services).

RESULTS

A total of 106 studies were included and there was evidence that improvements in mental health, social functioning, behaviour and forensic risk were associated with in-patient admission. There were two main models of in-patient psychiatric care described within the literature: admission to a specialist intellectual disability or general mental health in-patient service. Patients admitted to specialist intellectual disability in-patient services had greater complexity, but there were additional benefits, including fewer out-of-area discharges and lower seclusion rates.

CONCLUSIONS

There was evidence that admission to in-patient services was associated with improvements in mental health for this population. There was some evidence indicating better outcomes for those admitted to specialist services.

High Security Settings in Flanders: An Analysis of Discharged and Long-Term Forensic Psychiatric Patients

BACKGROUND

Two Forensic Psychiatric Centres (FPC) were implemented the last decade in Flanders in Ghent (2014) and Antwerp (2017). FPCs are forensic institutions for forensic psychiatric patients with a high recidivism risk and a high security need. The objective of FPCs is to create a care process with sufficient flow (from high to lower forms of security), and transitions (from specialized forensic care to regular psychiatric care).

AIMS

To examine the characteristics of the high security population in FPCs, treatment length, number of discharges, and discharge locations and to determine the profile of long-term patients within an FPC.

METHODS

A retrospective file study of an admission cohort of 654 patients admitted to FPC Ghent or FPC Antwerp was conducted. Sociodemographic, clinical, judicial and risk characteristics were analyzed. Bivariate analyses were used to test the difference between two groups: the group that was discharged to a lower security level vs. the group of long-term patients.

RESULTS

Most patients had psychosis and personality disorders, while comorbidity was also high. Judicial histories were extensive, with many sexual index offenses. During a 6-year follow-up period, the number of referrals back to prison was low. Nearly a third of the population was discharged to a setting with a lower security level. Long-term patients typically presented with more personality disorders, higher psychopathy traits and higher risk scores and were more frequently subjected to coercive measures during treatment.

CONCLUSIONS

The Flemish FPC population is characterized by a high proportion of sex offenders as well as a high proportion of personality-disordered patients. It is this last group, and the group with elevated psychopathy traits, who remain for longer than expected and is difficult to resocialize. This study further highlights the need for clear criteria to assess the conditions of these long-term patients in Flanders.

Migrants With Schizophrenia in Forensic Psychiatric Hospitals Benefit From High-Intensity Second Language Programs

Background: As a result of migration, an increasing number of patients in forensic psychiatric hospitals show poor skills in the national language, which can affect their treatment. Improving the second language (L2) of inpatients with schizophrenia may help to enable effective psychotherapy and thus reduce the risk of criminal recidivism and facilitate reintegration into society, for example because of a language-related higher degree of social functioning. For this purpose, a Hessian forensic psychiatric hospital established a ward specialized in L2 acquisition. The ward accommodates up to 21 patients with schizophrenia, who attend an L2 program consisting of 800-900 lessons within 1 year. Aims: The study aimed to evaluate whether patients on the specialized ward (experimental group) achieve at least Common European Framework of Reference (CEFR) level A2 in the L2 program. Additionally, it examined whether language acquisition is better among participants in the experimental group than among those on regular wards (control group). Methods: Achievements in the L2 were assessed by an L2 test 3 times: at the beginning of the program, after 6 months, and after 1 year. The impact of intelligence on achievements in L2 was evaluated using Raven's Standard Progressive Matrices. Results: The experimental group showed significantly better improvement than the control group. Literacy was a significant predictor of improvement in the L2. The majority of the experimental group reached at least CEFR level A2 after 1 year. Conclusions: High-intensity L2 programs are an effective way to improve the L2 of inpatients with schizophrenia in forensic psychiatric hospitals.
