Violence-Related Deaths Among People Released From Prison: A Data Linkage Study

Deaths among adults under supervision of the England and Wales' probation services: variation in individual and criminal justice-related factors by cause of death

BACKGROUND

The mortality rate among people under probation supervision in the community is greater than that among incarcerated people and that among the general population. However, there is limited research on the distinct vulnerabilities and risks underlying the causes of death in this population. In this retrospective cohort study, we examined the individual and criminal justice-related factors associated with different causes of death. Factors were assessed in relation to the type of supervision, distinguishing between those under post-custodial release and those serving a community sentence.

RESULTS

The study utilised the official data held by His Majesty's Prison and Probation Service in England and Wales on the deaths of men and women under probation supervision between 01 April 2019 and 31 March 2021 where the cause of death had been definitively recorded (n = 1770). The high risk of deaths primarily caused by external factors (i.e., suspected suicide (10%), homicide (5%), and drug-related death (26%)) in this population was confirmed. A Gaussian Graphical Model (GGM) demonstrated unique relationships with suspected suicide and drug-related deaths for known suicide risk, history of drug use and recent (< 28 days of death) enforcement action due to a breach of probation conditions. Our findings suggest that that familial violence and abuse may be relevant in suicide and drug-related deaths and that minority groups may experience disproportional risk to certain types of death.

CONCLUSIONS

This study identified unique risk indicators and modifiable factors for deaths primarily caused by external factors in this population within the health and justice spheres. It emphasised the importance of addressing health inequalities in this population and improved joint-working across health and justice. This involves ensuring that research, policies, training, and services are responsive to the complex needs of those under probation supervision, including those serving community sentences. Only then can we hope to see lower rates of death within this population.

When State Violence Comes Home: From Criminal Legal System Exposure to Intimate Partner Violence in a Time of Mass Incarceration

Exceptionally high rates of partner violence perpetration are evident among men returning from prison. Two bodies of scholarship, one on family stress and another on exposure to state violence, each suggest that criminal legal system exposure could promote partner violence perpetration via changes in men's behavioral health and interpersonal approach and in couples' conflict dynamics. Such relationships have not been tested in quantitative research. Structural equation models were fitted to longitudinal, couples-based survey data from the Multi-site Family Study on Incarceration, Parenting, and Partnering. Participants included men returning from a state prison term in five U.S. states (N = 1112) and their committed intimate or co-parenting partners (N = 1112). Models tested hypothesized pathways from three dimensions of criminal legal system exposure to later partner violence perpetration. In fitted models, men's childhood criminal legal system exposure predicts their post-prison partner violence perpetration via adult post-traumatic stress symptoms, reactivity, avoidance, and dysfunctional couple conflict dynamics. Men's cumulative criminal legal system exposure in adulthood predicts their post-prison partner violence perpetration via addiction and dysfunctional couple conflict. These initial results suggest that mass-scale incarceration could worsen partner violence via men's psychological and interpersonal adaptations to criminal legal system contact, particularly when such contact is sustained or occurs at a developmentally significant period in the life course.

Violence-related deaths among people released from incarceration: systematic review and meta-analysis of cohort studies

BACKGROUND

People released from incarceration have an increased risk of violence-related death. As deaths from violence are a rare event, meta-analysis is needed to calculate reliable estimates of this risk. We examined the crude mortality rates (CMRs), standardised mortality ratios (SMRs), and predictive factors for violence-related deaths among people released from incarceration.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE, PubMed, PsycINFO, Scopus, Web of Science, CINCH, and Criminal Justice Abstracts from inception to 14 September 2020 for cohort studies published in English that examined violence-related deaths occurring in the community following release from adult or youth incarceration. We used the Methodological Standard for Epidemiological Research (MASTER) scale to assess the quality of included studies. We conducted a random-effects meta-analysis to calculate pooled estimates of the CMRs and SMRs. Heterogeneity was assessed using univariable meta-regression. This review was registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42020209422).

FINDINGS

Our search identified 2,489 records, from which 11 studies met the eligibility criteria. The pooled CMR for violence-related deaths after release from incarceration was 78·7 per 100,000 person-years (95%CI 58·0-99·5). The pooled SMR was 7·6 (95%CI 2·4-12·8). The estimate of heterogeneity was high (I²≥99%) and the Cochran's Q test was significant (p<0·001) for the pooled CMR and SMR. Study design (prospective vs. retrospective; p=0·001) and type of incarceration facility (youth detention vs. prison; p=0·006) were identified as possible sources of heterogeneity for CMRs. Risk factors for violence-related death after release were reported in only five studies. These included being male (n=3), Black or Hispanic in the United States (n=3), and younger age at release from incarceration (n=2).

INTERPRETATION

People released from incarceration are almost eight times more likely to die from violence than the general population. Violence-related deaths are preventable, and the high rate at which they occur after release from incarceration represents an important public health issue requiring targeted, evidence-based response.

FUNDING

None.

Violence-related morbidity among people released from prison in Australia: A data linkage study

INTRODUCTION

People released from prison have an increased risk of morbidity, including from nonfatal violence. We examined the incidence and predictors of violence-related morbidity after release from prison and investigated whether there are differences according to sex and Indigenous status.

METHODS

Baseline data were collected from 1325 people within 6 weeks of release from prisons in Queensland, Australia, between 1 August 2008 and 31 July 2010. Data were linked to state-wide health (ambulance, emergency department and hospital) and prison records, and national death records until 31 July 2012. Predictors were identified using a multivariable Andersen-Gill model. Differences according to sex and Indigenous status were investigated using effect modification.

RESULTS

A total of 225 (18.2%) people experienced 410 violence-related events that were recorded in health records. The incidence was 12.8 per 100 person-years [95% confidence interval (CI) 11.7, 14.1]. Risk factors for violence-related morbidity included diagnosed mental illness [hazard ratio (HR) = 2.0, 95% CI 1.1, 3.8], substance use disorder (HR = 1.6, 95% CI 1.1, 2.3) or dual diagnosis (HR = 3.2, 95% CI 2.2, 4.8); high-risk alcohol use (HR = 2.1, 95% CI 1.5, 2.8); being Indigenous (HR = 1.7, 95% CI 1.2, 2.5); and two or more prison releases (HR = 1.7, 95% CI 1.2, 2.6). Indigenous status modified the risk of violence-related morbidity, with Indigenous men having twice the risk of non-Indigenous men (HR = 1.9, 95% CI 1.3, 2.8).

DISCUSSION AND CONCLUSIONS

Approximately one in five people released from prisons in Queensland experienced violence-related morbidity. Coordinated and continuous mental health and substance use treatment from prison to the community may reduce the risk of violence-related morbidity in this population.

Violence-related deaths among people released from incarceration: protocol for a systematic review

INTRODUCTION

Young people and adults released from incarceration have a risk of dying from violence that far exceeds that in the general population. Despite this, evidence regarding the incidence, elevated risk and predictive factors for violence-related deaths after release have not yet been synthesised. This information is important to inform the development of evidence-based approaches to effectively prevent deaths from violence in this population. This systematic review will synthesise the literature examining the crude mortality rates (CMRs), standardised mortality ratios (SMRs) and predictive factors for violence-related deaths among people released from incarceration.

METHODS AND ANALYSIS

We searched key electronic health, social science and criminology databases (MEDLINE, PubMed, PsycINFO, Scopus, Web of Science, CINCH, Criminal Justice Abstracts) for peer-reviewed cohort studies published in English on 14^th September 2020. Our primary outcome of interest is violence-related deaths occurring in the community following release from incarceration. We will not restrict study eligibility by year of publication or age of participants. The Methodological Standard for Epidemiological Research (MASTER) scale will be used to assess the quality of included studies. If there are sufficient studies and homogeneity between studies, we will conduct meta-analyses to calculate pooled estimates of CMRs, SMRs or predictive factors for violence-related deaths. If there is a sufficient number of included studies, meta-regression will be conducted to examine the influence of subgroups and methodological factors on the CMRs, SMRs or predictive factors. If the studies do not report sufficient data, or if there is substantial heterogeneity, findings will be presented in a narrative form.

ETHICS AND DISSEMINATION

This review is exempt from ethics approval as it will synthesise findings from published studies that have already obtained ethics approval. Our findings will be disseminated through a peer-reviewed journal article, and national and international conference and seminar presentations.
