Developing criminal justice liaison and diversion services: research priorities and international learning

Automatic Extraction of Research Themes in Epidemiological Criminology From PubMed Abstracts From 1946 to 2020: Text Mining Study

BACKGROUND

The emerging field of epidemiological criminology studies the intersection between public health and justice systems. To increase the value of and reduce waste in research activities in this area, it is important to perform transparent research priority setting considering the needs of research beneficiaries and end users along with a systematic assessment of the existing research activities to address gaps and harness opportunities.

OBJECTIVE

In this study, we aimed to examine published research outputs in epidemiological criminology to assess gaps between published outputs and current research priorities identified by prison stakeholders.

METHODS

A rule-based method was applied to 23,904 PubMed epidemiological criminology abstracts to extract the study determinants and outcomes (ie, "themes"). These were mapped against the research priorities identified by Australian prison stakeholders to assess the differences from research outputs. The income level of the affiliation country of the first authors was also identified to compare the ranking of research priorities in countries categorized by income levels.

RESULTS

On an evaluation set of 100 abstracts, the identification of themes returned an F1-score of 90%, indicating reliable performance. More than 53.3% (11,927/22,361) of the articles had at least 1 extracted theme; the most common was substance use (1533/11,814, 12.97%), followed by HIV (1493/11,814, 12.64%). The infectious disease category (2949/11,814, 24.96%) was the most common research priority category, followed by mental health (2840/11,814, 24.04%) and alcohol and other drug use (2433/11,814, 20.59%). A comparison between the extracted themes and the stakeholder priorities showed an alignment for mental health, infectious diseases, and alcohol and other drug use. Although behavior- and juvenile-related themes were common, they did not feature as prison priorities. Most studies were conducted in high-income countries (10,083/11,814, 85.35%), while countries with the lowest income status focused half of their research on infectious diseases (47/91, 52%).

CONCLUSIONS

The identification of research themes from PubMed epidemiological criminology research abstracts is possible through the application of a rule-based text mining method. The frequency of the investigated themes may reflect historical developments concerning disease prevalence, treatment advances, and the social understanding of illness and incarcerated populations. The differences between income status groups are likely to be explained by local health priorities and immediate health risks. Notable gaps between stakeholder research priorities and research outputs concerned themes that were more focused on social factors and systems and may reflect publication bias or self-publication selection, highlighting the need for further research on prison health services and the social determinants of health. Different jurisdictions, countries, and regions should undertake similar systematic and transparent research priority-setting processes.

Severe mental illness, common mental disorders, and neurodevelopmental conditions amongst 9088 lower court attendees in London, UK

BACKGROUND

Court Mental Health Liaison and Diversion Services (CMHLDS) have developed in some countries as a response to the over-representation of mental illness and other vulnerabilities amongst defendants presenting to criminal justice (or correctional) systems. This study examined the characteristics and rates of mental disorder of 9088 defendants referred to CMHLDS.

METHOD

The study analysed service level data, obtained from the National Health Service's mental health data set, to examine characteristics relating to gender, ethnicity and comorbidity of common mental and neurodevelopmental disorders at five CMHLDS across London between September 2015 and April 2017.

RESULTS

The sample included 7186 males (79.1%) and 1719 females (18.9%), the gender of 183 (2%) were not recorded. Of those referred, 6616 (72.8%) presented with an identifiable mental disorder and 503 (5.5%) with a neurodevelopmental disorder (NDD). Significantly higher rates of schizophrenia were reported amongst Black defendants (n = 681; 37.2%) and Asian defendants (n = 315; 29%), while higher rates of depression were found amongst White defendants (n = 1007; 22.1%). Substance misuse was reported amongst 2813 defendants (31%), and alcohol misuse amongst 2111 (23.2%), with significantly high rates of substance and alcohol misuse amongst defendants presenting with schizophrenia or personality disorder.

CONCLUSIONS

This is one of the largest studies to examine mental health needs and vulnerabilities amongst defendants presenting to CMHLDS. It will enable an improved understanding of the required service designs and resources required to manage the healthcare pathways for people attending CMHLDS.

Defendants with intellectual disability and autism spectrum conditions: the perspective of clinicians working across three jurisdictions

The treatment of vulnerable defendants by criminal justice systems or correctional systems varies within and between countries. The purpose of this paper is to examine three legal jurisdictions - New South Wales in Australia; Norway; England and Wales - to understand the extent of variation in practice within the court systems for defendants with intellectual disabilities (ID) and/or autism spectrum conditions (ASC). Two of the jurisdictions had a process for screening in place, either in police custody or at court, but this was not universally implemented across each jurisdiction. All three jurisdictions had a process for supporting vulnerable defendants through the legal system. Across the three jurisdictions, there was variation in disposal options from a mandatory care setting to hospital treatment to a custodial sentence for serious offences. This variation requires further international exploration to ensure the rights of defendants with ID or ASC are understood and safeguarded.

Evaluation of a liaison and diversion Court Mental Health Service for defendants with neurodevelopmental disorders

AIM

Neurodevelopmental disorders (NDD) may present as neuropsychiatric problems as well as impairments of motor, cognitive, social and communication functioning. This study describes the introduction of a specialist service with expertise in NDD into an existing court mental health liaison and diversion service to determine if the service would impact on the health needs or disposal outcomes of defendants.

METHODS

We examined referrals of defendants with NDD disorders over 30-months at a London Magistrates' Court. The pre-existing Court Mental Health (CMH) service was enhanced to provide additional expertise and hereafter referred to as the CMH + NDD Service. Baseline data including gender, ethnicity, remands and the rates of mental disorders was collected from the CMH Service using the existing minimum mental health service dataset. This was compared with data collected from the CMH + NDD Service.

RESULTS

We found the following rates of NDD 9.5 % (n = 43) for the CMH service, and 9.5 % (n = 79) for the CMH + NDD service. Although overall the rates were the same the number of defendants with a single NDD diagnosis was increased in the CMH + NDD service with ADHD 10 %, ASD and ID 4% higher, the rates of comorbid NDD decreased in the CMH + NDD service compared to baseline. Specific disorders such as depression were recorded at higher rates for NDD defendants in both phases, however, this did not reach significance. In contrast, schizophrenia and delusional disorders, alcohol and substance use were observed at much higher in the non-NDD defendants during both phases of the study. The rates of diagnosis of schizophrenia and delusional disorders increased for the NDD group within the CMH + NDD service. Following the first court appearance, there was a 10 % reduction in custodial remands for defendants with NDD who were seen by the CMH + NDD service (34.2 %, n = 25 in the CMH + NDD service vs 43.8 %, n = 14 in the CMH service).

CONCLUSION

The study found it is possible to successfully integrate practitioners with expertise of NDD into existing liaison and diversion services. This service enhancement demonstrated modest evidence of service effectiveness, including an increase in the detection of comorbid mental illness and a reduction in custodial remands for defendants with NDD. Further work needs to be completed to examine how this model can be rolled out across multiple courts and in particular, a cost-benefit analysis is required to understand whether an approach involving a cluster of Courts, as opposed to a single site is the most effective approach for this group of defendants.

Involving service users to identify research priorities in a UK forensic mental health service

AIMS AND METHOD

Patient and public involvement (PPI) is a priority for health research. PPI improves the relevance and quality of research. The study aimed to involve service users in identifying research priorities for the service. A two-phase adapted Delphi technique was used to generate a list of research topics from service users in secure in-patient mental health settings and on specialist mental health prison wings. Topic content analysis was undertaken. Service users were further consulted, and research themes were ranked in order of priority.

RESULTS

Of the eight research themes identified, the three given the highest priority by service users were, in descending order, physical health, future plans and moving on, and causes of illness and crime.

CLINICAL IMPLICATIONS

Service users are willing to be involved in setting research priorities for mental health services. Through non-tokenistic PPI, service users can uniquely shape the research agenda of mental health services.

Liaison and diversion services in South East London: Referral patterns over a 25-year period

Criminal justice liaison and diversion services identify people with mental health needs and ensure they receive appropriate support. We describe a 25-year period of one such service that deals with a population of 864,540 in South East London that was set up in 1991. We used data from three time periods. A diagnosis of a mental illness was recorded in 70.0-80.3% of court liaison and diversion referrals. The proportion receiving a hospital order declined from 15.4% in 1991/1992 to 1.1% in 2015/2016; 54/199 (27.1%) of referrals to the police liaison and diversion service were detained in hospital. Although the service is designed to support any individual with a mental health issue, these results suggest that it has dealt mainly with people who have severe mental illness. Further research is required to understand how best to benefit a wider range of people with mental health issues who attend the lower (Magistrates') courts, and whether screening for mental disorders can be applied in liaison and diversion settings to aid the implementation of national policy. We also need to understand how disposal decisions are made, and which are most effective.

Identifying research priorities to improve the health of incarcerated populations: results of citizens' juries in Australian prisons

Health disparities in incarcerated populations should guide investment in the health care and research of these communities. Although users of health-care services are important in providing input into decisions about research, the voices of people in prison are absent regarding research into their health. In this Health Policy paper, we present priorities for research into the health of people in prison according to people in prison themselves. By use of a deliberative research approach, citizens' juries were conducted in six prisons (three men's and three women's prisons) in Australia. Participants were selected following submissions of expression of interest forms that were distributed within the prisons. Prerecorded information by experts in the health of incarcerated people was shown to participants. Participants deliberated for up to 4 h before agreeing on five research priorities. All citizens' juries endorsed mental health as a number one research priority. Prison health-care services, alcohol and other drug use, education, and infectious diseases were identified as research priorities by most citizens' juries. Focal points within priorities included serious mental illness; grief and trauma; medication management; health-care service access, quality, and resources; drug withdrawal and peer support; prison-based needle and syringe programmes; and health and life skills education. If endeavours in research priority setting are to consider health equity goals, the views of our most health affected citizens need to be included.

Alternatives to custodial remand for women in the criminal justice system: A multi-sector approach

Throughout the world, women involved in criminal justice systems often present with substantial needs and vulnerabilities. Diverting vulnerable people away from prison is government policy in England and Wales, but full psychiatric and social assessments are expensive and hard to access. A screening and quick response initiative - alternatives to custodial remand for women (ACRW) - was implemented across three areas of London (West, South and East) to supplement existing court liaison and diversion services, to assess the feasibility of a supplementary custodial remand service as part of a women's specialist service pathway in the criminal justice system in England. Three mental health trusts and two voluntary sector providers offered this service enhancement - a screening and service link provision in three London boroughs between 2012 and 2014. We conducted a service evaluation using routinely collected service use record data. The service made 809 contacts, of whom 104 had contact on multiple occasions. Many were identified as at risk of self-harm (46%) or had histories of hospital admission for mental disorder (36%), but few were referred either to the liaison and diversion service or specialist mental health services. The largest group of referrals was to women's community services outside the health service (e.g. counselling, domestic violence or sexual abuse services). 180 women had dependent children and 22 were pregnant, increasing the urgency to find non-custodial alternatives. As well as confirming high levels of need amongst women entering the criminal justice system, this evaluation confirms the feasibility of working across sectors in this field, providing an extra layer of service that can complement existing liaison and diversion service provision. The service was responsive and most women using it were kept out of custody. Research is now required to understand the appropriateness of the referrals, the extent to which women follow them through and the impact on their mental health and desistance from offending.

Mental health in the criminal justice system: A pathways approach to service and research design

BACKGROUND

Care pathway approaches were introduced into health care in the 1980s and have become standard international practice. They are now being introduced more specifically for health care in the criminal justice system. Care pathway delivery has the theoretical advantage of encouraging a whole-systems approach for health and social care within the criminal justice system, but how well is it supported by empirical evidence?

AIMS

The aim of this study is to review the nature and extent of evidence streams supporting health care delivery within interagency pathway developments since 2000.

METHOD

We used an exploratory narrative method to review the nature and extent of evidence streams supporting health care delivery within interagency pathway developments since 2000. The available literature was reviewed using a keyword search approach with three databases: PubMed, Medline, and Google Scholar.

FINDINGS

Research in this field has covered police custody, courts, prisons, and the wider community, but there is little that follows the entire career through all these elements of offender placement. Main themes in the research to date, regardless of where the research was conducted, have been counting the disorder or the need, development and evaluation of screening tools, and evaluation of clinical intervention styles. Most evidence to date is simply observational, although the possibility of conducting randomised controlled trials of interventions within parts of the criminal justice system, especially prisons, is now well established.

CONCLUSIONS

Access to health care while passing through the criminal justice system is essential because of the disproportionately high rates of mental disorder among offenders, and the concept of structured pathways to ensure this theoretically satisfying, but as yet empirically unsupported. Further, substantial cuts in services, generally following government economies, are largely unresearched. Considerable investment in new possibilities, driven by both pressure groups and government, tend to be informed by good will and theory rather than hard evidence and are often not evaluated even after introduction. This must change.

Autistic spectrum disorder and offending behaviour – a brief review of the literature

Purpose

The purpose of this paper to synthesise much of the existing research on autistic spectrum disorder (ASD) and offending behaviour.

Design/methodology/approach

It considers three key areas, namely, first, a discussion about the nature of ASD and how it might be related to offending behaviour; second, a brief commentary about the prevalence of this population; and, finally, an exploration of the effective management and possible treatment outcomes.

Findings

Methodological limitations have resulted in variable findings which has hindered our understanding of this population. Some of the research is based on small, highly specialist samples making prevalence difficult to measure. The link between ASD and offending is still not well understood, and despite advances in staff training, awareness amongst practitioners remains an underdeveloped area, thus yielding variable treatment outcomes.

Originality/value

This review continues to demonstrate the urgent need for robust research in order to better understand the link between ASD and offending behaviour, to provide tailored, needs-led interventions, and reduce the risk of offending amongst this group as a whole.

Mental illness and the provision of mental health services in prisons

INTRODUCTION

Around 11 million people are held in prisons internationally, and criminal justice systems are overburdened with a high prevalence of multiple psychiatric disorders. In England and Wales over 200 000 people enter prisons each year, and in many cases, this facilitates their first contact with mental health services.

SOURCES OF DATA

Research, evaluations, government reports and independent reviews.

AREAS OF AGREEMENT

Screening, Triage, Assessment, Intervention and Re-integration (STAIR) are necessary components of prison mental health provision, offering an opportunity to improve the wellbeing of a complex population.

AREAS OF CONTROVERSY

There are serious problems with service provision across many parts of the world, with human rights abuses occurring in some States. Screening and service delivery models still require substantial development. In England and Wales, self-harm, self-inflicted deaths and violence are increasing.

GROWING POINTS

Introducing comprehensive mental health models throughout prisons would offer a massive public health initiative, providing new services for the socially disadvantaged. A rights-based framework would be useful in ensuring systemic improvements, especially in low and middle-income countries.

AREAS TIMELY FOR DEVELOPING RESEARCH

Mechanisms for screening and triage, specific interventions across a broad range of conditions, and practical re-integration models, should be submitted to research across international sites.

Contextualising health screening risk assessments in police custody suites - qualitative evaluation from the HELP-PC study in London, UK

Background

In the UK, police custody officers have a responsibility to screen for health morbidity and vulnerability among detainees. This study aimed to develop an understanding of the barriers to performing effective health screening in police custody suites, understand the impact of screening tools on practice within the custody suite, and to identify factors that could hinder or facilitate the future implementation of a new screening intervention in this environment.

Methods

A qualitative study was conducted alongside a quantitative evaluation of a novel screening tool. Qualitative methods included observation of the custody environment, semi-structured interviews with police staff, and elicitation of comments from detainees about their experiences of screening. Data were analysed inductively using thematic analysis. Normalization Process Theory (NPT) was used to inform data collection and as a framework for higher level analysis of findings.

Results

Five overall constructs were identified that develop understanding of the integration of health screening within custody: the workability of risk assessment screening tools; the effect of the custody environment and the people therein; shifts in professional roles and interrelationships amongst staff; cultural responses to risk and liability in police work; how infrastructure, knowledge and skills can impact on detainee safety.

Conclusions

Health and risk assessment screening in police custody is a complex and demanding activity which extends beyond the delivery of a screening tool. Professional roles, the demanding environment and police culture impact on the overall process. Recommendations for improved integration of health and risk assessment screening in wider police custody practice are proposed.

Defendants with autism spectrum disorders: what is the role of court liaison and diversion?

Purpose

The purpose of this paper is to examine the role of liaison and diversion services working in the lower courts (also known as Magistrates’ courts) with regard to autism spectrum disorders (ASDs) and their assessment, in particular, the role of pre-sentence and psychiatric reports and interviews.

Design/methodology/approach

Current practice is described in the lower courts in the context of current legislation and procedures.

Findings

When writing reports, there is a need for expertise to offer an opinion on future risk, disposal and what needs to be in place to support people with ASDs. No assumptions should be made when reporting on the basis of an ASD diagnosis alone and each case must be assessed on its individual merits while ensuring that individual human rights are protected.

Originality/value

There is currently a sparse literature examining ASD in court settings. This paper seeks to clarify the current practice.

Police custody health care: a review of health morbidity, models of care and innovations within police custody in the UK, with international comparisons

This paper is a scoping review of the available evidence regarding health care issues in police custody. It describes the types and prevalence of health disorders encountered in custody and provides an overview of current practice and recent innovations in police custody health care. In contrast to the health of prisoners, the health of police custody detainees has, until recently, received little academic or clinical attention. Studies on health care in police custody identified for this review are limited to a few geographical jurisdictions, including the UK, continental Europe, North America, and Australia. There are significant health concerns among police detainees including acute injury, chronic physical health problems, mental and cognitive disorders, and the risks associated with drug and alcohol intoxication or withdrawal. There is some evidence that deaths in police custody have reduced where attention has been paid to the latter issue. Police personnel continue to experience difficulties identifying detainees with health issues relevant to their safe detention, but research shows that the use of evidence-based screening tools improves detection of such morbidities. Innovations in police custody health care mainly relate to detainees with mental disorders, including improved identification of illness, timely access to mental health services, the protection of the rights of mentally disordered detainees, and the diversion of mentally disordered persons from the criminal justice system into appropriate health and social care interventions. There is a lack of rigorous research relating to interventions for physical health problems, protecting those at risk of substance withdrawal, and detainees with preexisting or peri-arrest injures. Research to improve the health of police custody detainees requires greater priority, focusing on case identification and service redesign to address high levels of morbidity and to facilitate health promotion and prevention activities.

Prison Mental Health In-reach: The Effect of Open Referral Pathways

In England and Wales, mental health in-reach teams manage high levels of mental disorder in prisons, but problems with reception screening and referral triage have been identified. As one potential solution, we examined the effect of an open referral pathway upon one in-reach team by evaluating its referrals and caseload across two time periods (in 2008 and 2011). There was a doubling of team referrals (from 101 to 203) with significantly improved identification of people with no mental health history. There was further evidence for a lowering of thresholds for referral and assessment, an approach that can be seen as helpful within a system that is known to under-identify mental health problems. Despite limitations, this evaluation offers some evidence for the effectiveness of open referral systems. It also raises questions about the potential effects of liaison and diversion services that are presently being piloted for national introduction.
