Self-harm and suicide attempts among incarcerated lesbian, gay and bisexual people in Australia

OBJECTIVES

Guided by minority stress theory, we explored the association between sexual identity, justice system involvement, self-harm and suicide attempts, among a cohort of incarcerated adults in Australia.

METHODS

A sample of 2698 adults incarcerated in Queensland and Western Australia were surveyed between 1 August 2008 and 12 August 2016 about their current psychological distress, mental health diagnoses, contact with mental health services, and lifetime and recent self-harm and suicide attempts. We used multivariable logistic regression to explore the relationship between sexual orientation, prior criminal justice system involvement, mental health and demographic factors.

RESULTS

Five percent of the sample identified as gay, lesbian or bisexual, with 37% of lesbian, gay, bisexual and other same-sex attracted individuals reporting that they had self-harmed (vs 14% of heterosexual peers; χ² = 52.4; p < 0.001) and 49% reporting a history of at least one suicide attempt (vs 23%; χ² = 49.2; p < 0.001). Lesbian, gay, bisexual and other same-sex attracted people were 2.1 times (95% confidence interval: [1.4, 3.3]) and 1.8 times (95% confidence interval: [1.2, 2.8]) more likely to report a history of self-harm and suicide attempt, respectively, than non-lesbian, gay, bisexual and other same-sex attracted respondents.

CONCLUSION

Intersectionality theory suggests that people who are navigating two or more marginalised identities often experience a compounding of internal and external stressors. Consistent with that theory, lesbian, gay, bisexual and other same-sex attracted people who experience incarceration may be at particularly high risk of self-harm and suicidal behaviour. Custodial settings should both improve cultural competency for frontline staff working with lesbian, gay, bisexual and other same-sex attracted individuals and improve access to mental health services during incarceration.

Is use of opioid agonist treatment associated with broader primary healthcare use among men with recent injecting drug use histories following release from prison? A prospective cohort study

BACKGROUND

A precipitous decline in health status among people recently released from prison is common. In Victoria, Australia, opioid agonist treatment (OAT) in the community involves frequent contact with primary care, potentially facilitating broader use of primary healthcare services. Among a cohort of men who injected drugs regularly pre-imprisonment, we estimated differences in rates of primary healthcare use and medication dispensation between people who did and did not receive OAT post-release.

METHODS

Data came from the Prison and Transition Health Cohort Study. Three-month post-release follow-up interviews were linked with primary care and medication dispensation records. Generalised linear models were fit with one exposure (OAT: none/partial/complete) for 13 outcomes relating to primary healthcare use, pathology testing, and medication dispensation, adjusted for other covariates. Coefficients were reported as adjusted incidence rate ratios (AIRR).

RESULTS

Analyses included 255 participants. Compared to no OAT use, both partial and complete OAT use were associated with increased rates of standard (AIRR: 3.02, 95%CI: 1.88-4.86; AIRR: 3.66, 95%CI: 2.57-5.23), extended (AIRR: 2.56, 95%CI: 1.41-4.67; AIRR: 2.55, 95%CI: 1.60-4.07) and mental health-related (AIRR: 2.71, 95%CI: 1.42-5.20; AIRR: 2.27, 95%CI: 1.33-3.87) general practitioner (GP) consultations, total medication (AIRR: 1.88, 95%CI: 1.19-2.98; AIRR: 2.40, 95%CI: 1.71-3.37), benzodiazepine (AIRR: 4.99, 95%CI: 2.81-8.85; AIRR: 8.30, 95%CI: 5.28-13.04) and gabapentinoid (AIRR: 6.78, 95%CI: 3.34-13.77; AIRR: 4.34, 95%CI: 2.37-7.94) dispensations, respectively. Partial OAT use was also associated with increased after-hours GP consultations (AIRR: 4.61, 95%CI: 2.24-9.48) and complete OAT use? with increased pathology utilisation (e.g. haematological, chemical, microbiological or immunological tissue/sample testing; AIRR: 2.30, 95%CI: 1.52-3.48).

CONCLUSION

We observed higher rates of primary healthcare use and medication dispensation among people who reported partial and complete OAT use post-release. Findings suggest that access to OAT post-release may have a collateral benefit in supporting broader health service utilisation, underscoring the importance of retention in OAT after release from prison.

Sex differences in suicide, suicidal ideation, and self-harm after release from incarceration: a systematic review and meta-analysis

PURPOSE

People released from incarceration are at increased risk of suicide compared to the general population. We aimed to synthesise evidence on the incidence of and sex differences in suicide, suicidal ideation, and self-harm after release from incarceration.

METHODS

We searched MEDLINE, EMBASE, PsycINFO, Web of Science and PubMed between 1 January 1970 and 14 October 2021 for suicide, suicidal ideation, and self-harm after release from incarceration (PROSPERO registration: CRD42020208885). We calculated pooled crude mortality rates (CMRs) and standardised mortality ratios (SMRs) for suicide, overall and by sex, using random-effects models. We calculated a pooled incidence rate ratio (IRR) comparing rates of suicide by sex.

RESULTS

Twenty-nine studies were included. The pooled suicide CMR per 100,000 person years was 114.5 (95%CI 97.0, 132.0, I2 = 99.2%) for non-sex stratified samples, 139.5 (95% CI 91.3, 187.8, I2 = 88.6%) for women, and 121.8 (95% CI 82.4, 161.2, I2 = 99.1%) for men. The suicide SMR was 7.4 (95% CI 5.4, 9.4, I2 = 98.3%) for non-sex stratified samples, 14.9 for women (95% CI 6.7, 23.1, I2 = 88.3%), and 4.6 for men (95% CI 1.3, 7.8, I2 = 98.8%). The pooled suicide IRR comparing women to men was 1.1 (95% CI 0.9, 1.4, I2 = 82.2%). No studies reporting self-harm or suicidal ideation after incarceration reported sex differences.

CONCLUSION

People released from incarceration are greater than seven times more likely to die by suicide than the general population. The rate of suicide is higher after release than during incarceration, with the elevation in suicide risk (compared with the general population) three times higher for women than for men. Greater effort to prevent suicide after incarceration, particularly among women, is urgently needed.

Mortality among people who have experienced homelessness: protocol for a systematic review and meta-analysis

INTRODUCTION

Homelessness is a major contributor to health inequalities. People who experience homelessness are at markedly increased risk of multiple and complex health morbidities which likely increase their susceptibility to early, preventable death. Despite this, the mortality burden in this group remains poorly understood, limited in part by insufficient synthesis of data at a global level. This systematic review will synthesise international literature examining rates of risk and protective factors for mortality among people who have experienced homelessness.

METHODS AND ANALYSIS

We will search MEDLINE, PsycINFO, Embase and PubMed for peer-reviewed cohort studies examining mortality among people who have experienced homelessness. No study eligibility restrictions will be placed on the date, country of origin, or language of publications, or age of the sample. We will assess the quality of included studies using the Methodological Standards for Epidemiological Research scale. Our measures of mortality will include: (A) incidence-all cause and cause specific, expressed as a crude mortality rate (CMR) per 1000 person-years, with 95% CI and (B) all cause and cause specific, indirectly standardised mortality ratios (SMRs) with 95%CI. Associations between risk and protective factors and all-cause and cause-specific mortality will be reported using pooled relative risk ratios with 95% CI. Where there are sufficient data, the influence of subgroup and methodological factors on CMRs, SMRs and predictive factors will be examined using meta-regression.

ETHICS AND DISSEMINATION

This study does not require institutional ethics review or approval as it will synthesise findings from published studies that have previously been granted relevant ethics approvals. Study findings will be disseminated through a peer-reviewed journal article, conference and seminar presentations. A plain language summary will be distributed through the authors' academic and professional networks.

Prospective study of retention in opioid agonist treatment and contact with emergency healthcare following release from prisons in Victoria, Australia

BACKGROUND

People recently released from prison engage with emergency healthcare at greater rates than the general population. While retention in opioid agonist treatment (OAT) is associated with substantial reductions in the risk of opioid-related mortality postrelease, it is unknown how OAT affects contact with emergency healthcare. In a cohort of men who injected drugs regularly prior to imprisonment, we described rates of contact with ambulance services and EDs, and their associations with use of OAT, in the 3 months after release from prison.

METHODS

Self-report data from a prospective observational cohort of men who regularly injected drugs before a period of sentenced imprisonment, recruited between September 2014 and May 2016, were linked to state-wide ambulance and ED records over a 3-month postrelease period in Victoria, Australia. We used generalised linear models to estimate associations between OAT use (none/interrupted/retained) and contact with ambulance and EDs postrelease, adjusted for other covariates.

RESULTS

Among 265 participants, we observed 77 ambulance contacts and 123 ED contacts over a median of 98 days of observation (IQR 87-125 days). Participants who were retained in OAT between prison release and scheduled 3-month postrelease follow-up interviews had lower rates of contact with ambulance (adjusted incidence rate ratio (AIRR) 0.33, 95% CI 0.14 to 0.76) and ED (AIRR 0.43, 95% CI 0.22 to 0.83), compared with participants with no OAT use postrelease. Participants with interrupted OAT use did not differ from those with no OAT use in rates of contact with ambulance or ED.

CONCLUSION

We found lower rates of contact with emergency healthcare after release among people retained in OAT, but not among people reporting interrupted OAT use, underscoring the benefits of postrelease OAT retention. Strategies to improve accessibility and support OAT retention after leaving prison are important for men who inject drugs.

Asthma-related mortality after release from prison: a retrospective data linkage study

BACKGROUND

People who experience incarceration are at increased risk of asthma and have a higher prevalence of risk factors associated with asthma-related mortality. However, there has been little research on the relationship between asthma and mortality in people released from prison.

OBJECTIVES

This study examined the association between asthma and all-cause and cause-specific mortality, and estimated the increased risk of asthma-related mortality among adults released from prison compared to the age- and sex-matched general population.

DESIGN

We used data from a nested case-control sample (N = 1658) within a retrospective cohort study of all adults released from prisons in Queensland, Australia, from 1994 to 2007 (N = 42015). Deaths were identified using linkage to national mortality records. Nested study cases were sampled from deaths, with a matched control from the cohort. We examined medical and case management records to identify risk factors potentially associated with mortality. Asthma-related mortality in the cohort was compared to that of the matched general population of Queensland.

RESULTS

People released from prison were more likely than their age and sex matched general population counterparts to have an asthma-related death (HR = 3.32 95%CI:2.14-5.16). Those who had been identified as having asthma in prison had increased odds of mortality from all-cause (OR = 1.86 95%CI:1.40-2.47), drug-related (OR = 2.5 95%CI:1.40-4.46), cardiovascular-related (OR = 3.2 95%CI:1.57-6.51), and respiratory-related (OR = 3.30 95%CI:1.63-6.70).

CONCLUSION

Among people exposed to incarceration, those with asthma are at elevated risk of death after release from custody. Improved management of respiratory disease in this population may contribute to reducing their high rate of preventable mortality.

Association between contact with mental health and substance use services and reincarceration after release from prison

Objective

People released from prison who experience mental health and substance use problems are at high risk of reincarceration. This study aimed to examine the association between contact with mental health and substance use treatment services, and reincarceration, among adults released from prison.

Methods

Pre-release survey data from 1,115 adults released from prisons in Queensland, Australia were linked with administrative health and correctional records covering a median of 787 days post-release. We constructed marginal structural Cox proportional hazards models, adjusting for pre-release variables and time-varying indicators of emergent mental health and substance use problems, to examine the association between contact with mental health and substance use treatment services, and reincarceration.

Results

The adjusted hazard ratio (AHR) for reincarceration associated with mental health service contact was 1.76 (95%CI 1.23,2.51). Among those not on parole following release, the AHR for reincarceration associated with substance use treatment service contact was 3.16 (95%CI 2.09,4.77); we found no evidence for an association among those who were released on parole (AHR = 1.07; 95%CI 0.80,1.43).

Conclusions

Although we cannot eliminate the possibility of residual confounding, our findings suggest that infrequent or unsustained contact with community-based mental health and substance use treatment services is not protective against reincarceration, and may even be iatrogenic. Increased investment in high-quality and timely behavioural health services for people released from prison may simultaneously improve health outcomes, and reduce reincarceration.

Psychiatric well-being among men leaving prison reporting a history of injecting drug use: A longitudinal analysis

BACKGROUND

Community reintegration from prison is typically stressful, with several health and social outcomes impacting psychiatric well-being during this time, often exacerbated among individuals with histories of drug use. Longitudinal data was used to assess change in psychiatric well-being over 2 years following release from prison among men who reported a recent history of injecting drug use.

METHODS

Data for this study come from the Prison and Transition Health cohort study of 400 men recruited in prison prior to release and followed up over three time points. Psychiatric well-being was assessed using the 12-item General Health Questionnaire. We calculated change in individual General Health Questionnaire scores between interviews and identified covariates associated with General Health Questionnaire score using linear mixed-effects regression.

RESULTS

Data from 690 follow-up interviews among 326 participants were included in analyses. There was considerable variation in individuals' General Health Questionnaire scores. Moving accommodation frequently and frequent illicit drug injections were associated with an increase in General Health Questionnaire score (i.e. decline in psychiatric well-being). Two or more prior adult imprisonment episodes, social supports and past month primary healthcare attendance were associated with a decrease in General Health Questionnaire score.

CONCLUSION

Our findings identify health, social and structural influences on psychiatric well-being after release from prison that can inform re-entry programmes to support community reintegration.

Multimorbidity and quality of primary care after release from prison: a prospective data-linkage cohort study

Background

The period after release from prison can be challenging, especially due to a higher risk of morbidity and mortality despite commonly increased use of healthcare services. However, little is known about the quality of the healthcare offered to this population, which limits the possibility of addressing this important health inequity. This study characterised multimorbidity and investigated the relationship between multimorbidity and quality of primary healthcare in adults within 2 years after release from prison.

Methods

This was a prospective cohort study of 1046 participants of a service brokerage intervention after release from prison between August 2008 and July 2010 in Queensland, Australia. Participants had their baseline survey and clinical data linked prospectively with their medical, correctional and death records. Multimorbidity was ascertained using the Cumulative Illness Rating Scale and classified into three categories: none, moderate (morbidity in 2–3 domains) and complex (morbidity in 4 or more domains). Outcomes were Usual Provider Continuity Index (UPCI), Continuity of Care (COC) Index, and having at least one extended primary care consultation (> 20 minutes). Descriptive statistics and logistic regression were used in the analyses.

Results

Multimorbidity was present for 761 (73%) participants, being more prevalent among females (85%) than males (69%), p < 0.001. Moderate multimorbidity was not associated with UPCI or COC, but was associated with having at least one long consultation (AOR = 1.64; 95% CI:1.14–2.39), after adjusting for covariates. Complex multimorbidity was positively associated with all outcomes in the adjusted models. Indigenous status was negatively associated with UPCI (AOR = 0.54; 95% CI: 0.37–0.80) and COC (AOR = 0.53; 95% CI: 0.36–0.77), and people younger than 25 years were at 36% lower odds (AOR = 0.64; 95% CI: 0.44–0.93) of having a long consultation than the middle-aged group (25–44 years) in the adjusted models.

Conclusion

Moderate multimorbidity was associated with having at least one extended primary care consultation, but not with adequate continuity of care, for adults within 2 years of being released from prison. Nearly half of those with complex multimorbidity did not receive adequate continuity of care. The quality of primary care is inadequate for a large proportion of adults released from prison, constituting an important and actionable health inequity.

Impact of dual diagnosis on healthcare and criminal justice costs after release from Queensland prisons: a prospective cohort study

BACKGROUND

People released from prison have poorer health than the general public, with a particularly high prevalence of mental illness and harmful substance use. High-frequency use of hospital-based services is costly, and greater investment in transitional support and primary care services to improve the health of people leaving prison may therefore be cost-effective.

METHODS

A prospective cohort study of 1303 men and women released from prisons in Queensland, Australia, between 2008 and 2010, using linked data was performed. We calculated healthcare costs and the cost of re-incarceration. We compared healthcare costs to the general public, and assessed the impact of past mental illness, substance use disorder, and dual diagnosis on both healthcare and criminal justice costs.

RESULTS

Healthcare costs among the cohort were 2.1-fold higher than expected based on costs among the public. Dual diagnosis was associated with 3.5-fold higher healthcare costs (95% CI 2.6-4.6) and 2.8-fold higher re-incarceration costs (95% CI 1.6-5.0), compared with no past diagnosis of either mental illness or substance use disorder.

CONCLUSIONS

People released from prison incur high healthcare costs, primarily due to high rates of engagement with emergency health services and hospital admissions. Comorbid mental illness and substance use disorders are associated with high health and criminal justice costs among people recently released from prison.

Interventions to reduce suicidal thoughts and behaviours among people in contact with the criminal justice system: A global systematic review

BACKGROUND

People who experience incarceration die by suicide at a higher rate than those who have no prior criminal justice system contact, but little is known about the effectiveness of interventions in other criminal justice settings. We aimed to synthesise evidence regarding the effectiveness of interventions to reduce suicide and suicide-related behaviours among people in contact with the criminal justice system.

METHODS

We searched Embase, PsycINFO, MEDLINE, and grey literature databases for articles published between 1 January 2000 and 1 June 2021. The protocol was registered with PROSPERO (CRD42020185989).

FINDINGS

Thirty-eight studies (36 primary research articles, two grey literature reports) met our inclusion criteria, 23 of which were conducted in adult custodial settings in high-income, Western countries. Four studies were randomised controlled trials. Two-thirds of studies (n=26, 68%) were assessed as medium quality, 11 (29%) were assessed as high quality, and one (3%) was assessed as low quality. Most had considerable methodological limitations and very few interventions had been rigorously evaluated; as such, drawing robust conclusions about the efficacy of interventions was difficult.

INTERPRETATION

More high-quality evidence from criminal justice settings other than adult prisons, particularly from low- and middle-income countries, should be considered a priority for future research.

Prevalence of co-occurring mental illness and substance use disorder and association with overdose: a linked data cohort study among residents of British Columbia, Canada

AIMS

To estimate the treated prevalence of mental illness, substance use disorder (SUD) and dual diagnosis and the association between dual diagnosis and fatal and non-fatal overdose among residents of British Columbia (BC), Canada.

DESIGN

A retrospective cohort study using linked health, income assistance, corrections and death records.

SETTING

British Columbia (BC), Canada.

PARTICIPANTS

A total of 921 346 BC residents (455 549 males and 465 797 females) aged 10 years and older.

MEASUREMENTS

Hospital and primary-care administrative data were used to identify a history of mental illness only, SUD only, dual diagnosis or no history of SUD or mental illness (2010-14) and overdoses resulting in medical care (2015-17). We calculated crude incidence rates of non-fatal and fatal overdose by dual diagnosis history. Andersen-Gill and competing risks regression were used to examine the association between dual diagnosis and non-fatal and fatal overdose, respectively, adjusting for age, sex, comorbidities, incarceration history, social assistance, history of prescription opioid and benzodiazepine dispensing and region of residence.

FINDINGS

Of the 921 346 people in the cohort, 176 780 (19.2%), 6147 (0.7%) and 15 269 (1.7%) had a history of mental illness only, SUD only and dual diagnosis, respectively; 4696 (0.5%) people experienced 688 fatal and 6938 non-fatal overdoses. In multivariable analyses, mental illness only, SUD only and dual diagnosis were associated with increased rate of non-fatal [hazard ratio (HR) = 1.8, 95% confidence interval (CI) = 1.6-2.1; HR = 9.0, 95% CI = 7.0-11.5, HR = 8.7, 95% CI = 6.9-10.9, respectively] and fatal overdose (HR = 1.6, 95% CI = 1.3-2.0, HR = 4.3, 95% CI = 2.8-6.5, HR = 4.1, 95% CI = 2.8-6.0, respectively) compared with no history.

CONCLUSIONS

In a large sample of residents of British Columbia (Canada), approximately one in five people had sought care for a substance use disorder or mental illness in the past 5 years. The rate of overdose was elevated in people with a mental illness alone, higher again in people with a substance use disorder alone and highest in people with a dual diagnosis. The adjusted hazard rates were similar for people with substance use disorder only and people with a dual diagnosis.

Circumstances and toxicology of violence-related deaths among young people who have had contact with the youth justice system: a data linkage study

Background

Young people who have had contact with the youth justice system have an increased risk of dying from violence. Examining the context of violence-related deaths is essential in informing prevention strategies. We examined the circumstances and toxicology of violence-related deaths among young people who have had contact with the youth justice system in Queensland, Australia.

Methods

This data linkage study linked youth justice records from Queensland, Australia (30 June 1993-1 July 2014) on 48,670 young people to national death and coroner records (1 July 2000-1 January 2017). Circumstances and toxicology of deaths were coded from coroner’s records. We calculated the incidence of violence-related deaths that were reported to a coroner. Fisher’s exact tests were used to examine crude differences in the circumstances and toxicology of violence-related death, according to sex and Indigenous status.

Results

There were 982 deaths reported to a coroner in the cohort. Of which, 36 (4%) were from violence-related causes (incidence: 6 per 100,000 person-years, 95% confidence interval: 4-8). People who died from violence were most frequently male (n = 28/36; 78%), and almost half were Indigenous (n = 16/36; 44%). The majority of violence-related deaths involved a weapon (n = 24/36; 67%), most commonly a knife (n = 17/36; 47%). Compared to men where the violent incident was most frequently preceded by an altercation (n = 12/28; 43%), for women it was frequently preceded by a relationship breakdown or argument (n < 5; p = 0.004). Substances most commonly present in toxicology reports were cannabis (n = 16/23; 70%) and alcohol (n = 15/23; 65%).

Conclusions

Therapeutic alcohol and other drug programs, both in the community and detention, are likely important for reducing violence-related deaths among young people who have had contact with the youth justice system. The majority of violence-related deaths among women were in the context of intimate partner violence, indicating the urgent need for interventions that prevent intimate partner violence in this population. Diversion programs and increased investment in health and social services may reduce the overrepresentation of Indigenous people in the youth justice system and in violence-related deaths.

Emergency department presentations in the first weeks following release from prison among men with a history of injecting drug use in Victoria, Australia: A prospective cohort study

OBJECTIVE

Rates of emergency department (ED) use are higher among people released from prison than in the general population. However, little is known about ED presentations specifically among people with a history of injecting drug use (IDU) leaving prison. We measured the incidence of ED presentation in the three months following release from prison, among a cohort of men with histories of IDU, and determined pre-release characteristics associated with presenting to an ED during this period.

METHODS

We analysed linked survey and administrative data from the Prison and Transition Health (PATH) study (N = 400) using multiple-failure survival analysis.

RESULTS

Twenty-one percent (n = 81/393) of the cohort presented to an ED at least once within the three months after release from prison. The incidence of ED presentation was highest in the first six days after release. Cox proportional hazards modelling showed that a history of in-patient psychiatric admission and housing instability were associated with increased hazard of an ED presentation, and identifying as Aboriginal and Torres Strait Islander was associated with decreased hazard.

CONCLUSIONS

In our study, ED presentations following release from prison among people with a history of IDU was linked to acute health risks related to known mental health and social vulnerabilities in this population. Greater collaboration and systems integration between prison and community health and support services is needed to reduce presentations to ED and associated morbidities among people with a history of IDU after release from prison.

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

People released from prison are a socially marginalized group and are at high risk of death from preventable causes, including violence. Despite this, little is known about the epidemiology of violence-related death (VRD) after release from prison. This knowledge is essential for developing targeted, evidence-informed violence prevention strategies. We examined VRDs among a representative sample of people released from prisons in Queensland, Australia, by sex and Indigenous status. Correctional records for all people (aged ≥17 years) released from prisons from January 1994 until December 2007 (N = 41,970) were linked probabilistically with the National Death Index. The primary outcome was VRD following release from prison. We calculated crude mortality rates (CMRs) and standardized mortality ratios (SMRs) standardized by age and sex to the Australian population. We used Cox regression to identify predictors of VRD. Of 2,158 deaths after release from prison, 3% (n = 68) were violence-related. The SMR for VRD was 10.0 (95% confidence interval (CI): [7.9, 12.7]) and was greatest for women (SMR = 16.3, 95% CI: [8.2, 32.7]). The rate of VRD was 2.5 deaths per 10,000 person-years (95% CI: [2.0, 3.2]) and was highest between 2 and 6 months after release from prison (CMR = 6.3, 95% CI: [3.4, 11.6]). Risk factors for VRD included short sentences (<90 days; for males and non-Indigenous people) and experiencing two or more imprisonments (for non-Indigenous people). No significant risk factors for VRD were identified for women or Indigenous people. People released from prison die from violence at a rate that is greatly elevated compared with the general population, with women experiencing the greatest elevation in risk. Reducing the number of VRDs in this population could improve the health and wellbeing of some of our most marginalized community members.

Optimising emergency department and acute care for people experiencing mental health problems: a nominal group study

ObjectiveThe aim of this study was to identify potential model of care approaches and systems processes for people presenting to acute healthcare settings with mental health problems, including mental illnesses.MethodsFive (consensus) nominal group technique sessions were conducted in 2019 with a purposive sample of stakeholders from health, police, ambulance and consumer agencies (n = 21). Sessions were recorded, transcribed and analysed for thematic content.ResultsPotential model of care approaches and systems processes for people with mental health problems in the emergency department include: a skilled collaborative approach to care; consumer-focused service; knowledge improvement; early assessment; the development of models, systems and processes; and the built environment. In the broader acute care setting, the themes of formal care, linking of services, enhancing informal and innovative care options, improving information sharing and enhancing training and education were identified.ConclusionsCoherent and multifaceted approaches to the provision of care to people with mental health problems and diagnosed mental illnesses who are requiring emergency care include the linking and sharing of systems and information, changing the built environment and exploring new models of service delivery.What is known about the topic?There is considerable evidence of interventions used in the emergency department and acute healthcare settings for this vulnerable group of people with mental health problems and diagnosed mental illnesses; however, the evidence for appropriate model of care approaches and systems processes is limited.What does this paper add?For people with mental health problems in emergency departments and for people with diagnosed mental illnesses in acute care settings, targeted directions to further support treatment include the linking and sharing of systems and information, changing the built environment and exploring new models of service delivery.What are the implications for practitioners?Planning changes to services for mental health clients with acute problems needs to incorporate clinicians, health service planners, architects and a range of emergency services personnel.

A rapid review of early guidance to prevent and control COVID-19 in custodial settings

BACKGROUND

With over 11 million people incarcerated globally, prevention and control of COVID-19 in custodial settings is a critical component of the public health response. Given the risk of rapid transmission in these settings, it is important to know what guidance existed for responding to COVID-19 in the early stages of the pandemic. We sought to identify, collate, and summarise guidance for the prevention and control of COVID-19 in custodial settings in the first six months of 2020. We conducted a systematic search of peer-reviewed and grey literature, and manually searched relevant websites to identify publications up to 30 June 2020 outlining recommendations to prevent and/or control COVID-19 in custodial settings. We inductively developed a coding framework and assessed recommendations using conventional content analysis.

RESULTS

We identified 201 eligible publications containing 374 unique recommendations across 19 domains including: preparedness; physical environments; case identification, screening, and management; communication; external access and visitation; psychological and emotional support; recreation, legal, and health service adaptation; decarceration; release and community reintegration; workforce logistics; surveillance and information sharing; independent monitoring; compensatory measures; lifting control measures; evaluation; and key populations/settings. We identified few conflicting recommendations.

CONCLUSIONS

The breadth of recommendations identified in this review reflects the complexity of COVID-19 response in custodial settings. Despite the availability of comprehensive guidance early in the pandemic, important gaps remain in the implementation of recommended prevention and control measures globally, and in the availability of evidence assessing their effectiveness on reducing COVID-19 disease, impact on people in custody and staff, and implementation.

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.

Fatal overdoses after release from prison in British Columbia: a retrospective data linkage study

BACKGROUND

People recently released from prison are at increased risk of preventable death; however, the impact of the current overdose epidemic on this population is unknown. We aimed to document the incidence and identify risk factors for fatal overdose after release from provincial prisons in British Columbia.

METHODS

We conducted a retrospective, population-based, open cohort study of adults released from prisons in BC, using linked administrative data. Within a random 20% sample of the BC population, we linked provincial health and correctional records from 2010 to 2017 for people aged 23 years or older as of Jan. 1, 2015, who were released from provincial prisons at least once from 2015 to 2017. We identified exposures that occurred from 2010 to 2017 and deaths from 2015 to 2017. We calculated the piecewise incidence of overdose-related and all-cause deaths after release from prison. We used multivariable, mixed-effects Cox regression to identify predictors of all-cause death and death from overdose.

RESULTS

Among 6106 adults released from prison from 2015 to 2017 and followed in the community for a median of 1.6 (interquartile range 0.9-2.3) years, 154 (2.5%) died, 108 (1.8%) from overdose. The incidence of all-cause death was 16.1 (95% confidence interval [CI] 13.7-18.8) per 1000 person-years. The incidence of overdose deaths was 11.2 (95% CI 9.2-13.5) per 1000 person-years, but 38.8 (95% CI 3.2-22.6) in the first 2 weeks after release from prison. After adjustment for covariates, the hazard of overdose death was 4 times higher among those who had been dispensed opioids for pain.

INTERPRETATION

People released from prisons in BC are at markedly increased risk of overdose death. Overdose prevention must go beyond provision of opioid agonist treatment and naloxone on release to address systemic social and health inequities that increase the risk of premature death.

Risk of overdose-related death for people with a history of incarceration

BACKGROUND AND AIMS

Reported associations between previous incarceration and the risk of overdose-related death are substantially heterogeneous, and previous studies are limited by an inability to control for confounding factors in risk assessment. This study investigated the associations of overdose-related death with previous incarceration and the number or cumulative duration of previous incarcerations, and individual or neighborhood characteristics that may potentially modify the associations.

DESIGN AND SETTING

A cohort study using a 20% random sample of residents in British Columbia, Canada.

PARTICIPANTS

A total of 765 690 people aged 23 years or older at baseline as of 1 January 2015. Mean age was 50 years; 49% were males.

MEASUREMENTS

Previous incarcerations that occurred during the 5-year exposure period (January 2010 to December 2014) were identified using provincial incarceration records. Overdose-related deaths that occurred during the 3-year follow-up period (January 2015 to December 2017) were identified using linked administrative health data. Baseline individual and neighborhood characteristics were retrieved from the provincial health insurance data.

FINDINGS

In the cohort, 5743 people had an incarceration history during the exposure period, and 634 people died from drug overdose during the follow-up period. The mortality rate was 897 and 22 per 100 000 person-years for people who did and did not have an incarceration history, respectively. After adjusting for baseline individual and neighborhood characteristics (without any interaction term), people who had an incarceration history were 4.04 times (95% confidence interval 3.23-5.06) more likely to die from drug overdose compared with people without an incarceration history. The association was stronger for females, people without diagnoses of substance use disorder and people without dispensation of opioids for pain or benzodiazepines (P < 0.001 for each interaction term). There was no discernible linear trend between the number or cumulative duration of previous incarcerations and the risk of overdose-related death.

CONCLUSIONS

Previous incarceration appears to be a major risk factor for overdose-related death.
