Candida auris in US Correctional Facilities.

Candida auris is an emerging fungal pathogen that typically affects patients in healthcare settings. Data on C. auris cases in correctional facilities are limited but are needed to guide public health recommendations. We describe cases and challenges of providing care for 13 patients who were transferred to correctional facilities during January 2020-December 2022 after having a positive C. auris specimen. All patients had positive specimens identified while receiving inpatient care at healthcare facilities in geographic areas with high C. auris prevalence. Correctional facilities reported challenges managing patients and implementing prevention measures; those challenges varied by whether patients were housed in prison medical units or general population units. Although rarely reported, C. auris cases in persons who are incarcerated may occur, particularly in persons with known risk factors. Measures to manage cases and prevent C. auris spread in correctional facilities should address setting-specific challenges in healthcare and nonhealthcare correctional environments.

Screening for Chlamydia and Gonorrhea in Youth Correctional Facilities, Utah, USA.

We reviewed data obtained in October 2021-May 2023 from youth who reported a history of sexual activity upon admission to 1 of 12 juvenile justice facilities in Utah, USA, that offered screening for Chlamydia trachomatis and Neisseria gonorrhoeae. Urinalysis revealed C. trachomatis positivity of 10.77%, N. gonorrhoeae positivity of 1.08%, and coinfection C. trachomatis N. gonorrhoeae) of 0.90%. Prevalence of infection was similar for youths in rural and urban facilities. A total of 12.01% of those identifying as male and 14.01% of those identifying as female tested positive for C. trachomatis, N. gonorrhoeae, or coinfection. Of young adults who tested positive, 74.65% received their results while incarcerated, all of whom accepted treatment. Our research underscores the feasibility of providing prompt C. trachomatis/N. gonorrhoeae screening and treatment in juvenile correctional facilities. The pervasiveness of infection emphasizes the urgent need for early identification and treatment for C. trachomatis and N. gonorrhoeae in incarcerated youth nationwide.

The Association Between Prior Mental Health Service Utilization and Risk of Recidivism among Incarcerated Ontario Residents.

BACKGROUND: There is mixed evidence on the link between mental health and addiction (MHA) history and recidivism. Few studies have examined post-release MHA care. Our objective was to examine the association between prior (pre-incarceration) MHA service use and post-release recidivism and service use. METHODS: We conducted a population-based cohort study linking individuals held in provincial correctional institutions in 2010 to health administrative databases. Prior MHA service use was assigned hierarchically in order of hospitalization, emergency department visit and outpatient visit. We followed up individuals post-release for up to 5 years for the first occurrence of recidivism and MHA hospitalization, emergency department visit and outpatient visit. We use Cox-proportional hazards models to examine the association between prior MHA service use and each outcome adjusting for prior correctional involvement and demographic characteristics. RESULTS: Among a sample consisting of 45,890 individuals, we found that prior MHA service use was moderately associated with recidivism (hazard ratio (HR): 1.20-1.50, all P < 0.001), with secondary analyses finding larger associations for addiction service use (HR range: 1.34-1.54, all P < 0.001) than for mental health service use (HR range: 1.09-1.18, all P < 0.001). We found high levels of post-release MHA hospitalization and low levels of outpatient MHA care relative to need even among individuals with prior MHA hospitalization. DISCUSSION: Despite a high risk of recidivism and acute MHA utilization post-release, we found low access to MHA outpatient care, highlighting the necessity for greater efforts to facilitate access to care and care integration for individuals with mental health needs in correctional facilities.

The cumulative risk of jail incarceration.

Research on incarceration has focused on prisons, but jail detention is far more common than imprisonment. Jails are local institutions that detain people before trial or incarcerate them for short sentences for low-level offenses. Research from the 1970s and 1980s viewed jails as "managing the rabble," a small and deeply disadvantaged segment of urban populations that struggled with problems of addiction, mental illness, and homelessness. The 1990s and 2000s marked a period of mass criminalization in which new styles of policing and court processing produced large numbers of criminal cases for minor crimes, concentrated in low-income communities of color. In a period of widespread criminal justice contact for minor offenses, how common is jail incarceration for minority men, particularly in poor neighborhoods? We estimate cumulative risks of jail incarceration with an administrative data file that records all jail admissions and discharges in New York City from 2008 to 2017. Although New York has a low jail incarceration rate, we find that 26.8% of Black men and 16.2% of Latino men, in contrast to only 3% of White men, in New York have been jailed by age 38 y. We also find evidence of high rates of repeated incarceration among Black men and high incarceration risks in high-poverty neighborhoods. Despite the jail's great reach in New York, we also find that the incarcerated population declined in the study period, producing a large reduction in the prevalence of jail incarceration for Black and Latino men.

Intellectual and developmental disabilities in Ontario's criminal justice and forensic mental health systems: Using data to tell the story.

BACKGROUND: International studies show that adults with intellectual and developmental disabilities (IDD) are disproportionately represented in the criminal justice and forensic mental health systems; however, it is difficult to capture their involvement across systems in any one jurisdiction. AIMS: The current study aimed to estimate the prevalence of IDD across different parts of the criminal justice and forensic mental health systems in Ontario and to describe the demographic and clinical profiles of these individuals relative to their counterparts without IDD. METHODS: This project utilised administrative data to identify and describe the demographic and clinical characteristics of adults with IDD and criminal justice or forensic involvement across four sectors: federal correctional facilities, provincial correctional facilities, forensic inpatient mental health care and community mental health programmes. Questions were driven by and results were contextualised by a project advisory group and people with lived experience from the different sectors studied, resulting in a series of recommendations. RESULTS: Adults with IDD were over-represented in each of the four settings, ranging from 2.1% in federal corrections to 16.7% in forensic inpatient care. Between 20% (forensic inpatient) and 38.4% (provincial corrections) were under the age of 25 and between 34.5% (forensic inpatient) and 41.8% (provincial corrections) resided in the lowest income neighbourhoods. Medical complexity and rates of co-occurring mental health conditions were higher for people with IDD than those without IDD in federal and provincial corrections. CONCLUSIONS: Establishing a population-based understanding of people with IDD within these sectors is an essential first step towards understanding and addressing service and care needs. Building on the perspectives of people who work in and use these systems, this paper concludes with intervention recommendations before, during and after justice involvement.

Examining the Past Injustices Suffered by Those in Corrections and the General Public: A New Therapeutic Approach May Be Necessary.

One under-researched area within corrections is the connection among (a) past adverse events, particularly in the form of injustices against those who now are incarcerated, (b) crimes committed and then (c) healing from the effects of that past adversity of injustice. Might those who have experienced severe injustices against them develop an anger or a hatred that then is displaced onto others, leading to arrest, conviction and imprisonment? This is not to imply that societies condone illegal behaviour but instead to assist in the healing from the adversity so that future crime is reduced. As a first step in this sequence, the study here examined in detail the kinds of injustices suffered by men in a maximum-security correctional institution (N = 103) compared with men in a medium-security environment (N = 37) and in the general public (N = 96). Findings indicated differences between those in the general public and those in the two correctional contexts. The latter two groups had (a) a higher severity of injustices against them (rated by a panel of researchers), (b) a more negative current impact that past injustices are having on them (also rated by a panel of researchers), (c) more reports that the injustices contributed to their choices to harm others, (d) more serious types of hurt (such as sexual abuse), (e) a stronger degree of self-reported hurt and (f) more injustices from family members. Implications for correctional rehabilitation to reduce the negative psychological effects caused by the injustices of others are discussed.

Bringing experiences of healthcare in custody into quality improvement.

Patient experience is an essential component of safe and high-quality healthcare, yet rarely examined in the context of carceral settings. This article describes a project undertaken by the Ontario Ministry of the Solicitor General to collect evidence and perspectives on how to bring patient experiences of healthcare services delivered in provincial correctional facilities into ongoing quality improvement work. We first conducted a scoping review and jurisdictional scan to learn from existing processes and experiences. We then engaged frontline healthcare providers delivering services in custody and people with recent experience of incarceration regarding priority measures and processes for data collection and mechanisms for implementing evidence-based change. This article describes methods used to engage stakeholders, including a survey and focus groups, as well as key lessons learned. This work is relevant to readers experiencing barriers to patient engagement, interested in collaborative research processes, and developing services for people who have experienced incarceration.

Testing Frequency Matters: An Evaluation of the Diagnostic Performance of a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Rapid Antigen Test in US Correctional Facilities.

BACKGROUND: The Centers for Disease Control and Prevention recommends serial rapid antigen assay collection within congregate facilities. Although modeling and observational studies from communities and long-term care facilities have shown serial collection provides adequate sensitivity and specificity, the accuracy within correctional facilities remains unknown. METHODS: Using Connecticut Department of Correction data from 21 November 2020 to 15 June 2021, we estimated the accuracy of a rapid assay, BinaxNOW (Abbott), under 3 collection strategies: single test collection and serial collection of 2 and 3 tests separated by 1-4 days. The sensitivity and specificity of the first (including single), second, and third serially collected BinaxNOW tests were estimated relative to RT-PCRs collected ≤1 day of the BinaxNOW test. The accuracy metrics of the testing strategies were then estimated as the sum (sensitivity) and product (specificity) of tests in each strategy. RESULTS: Of the 13 112 residents who contributed ≥1 BinaxNOW test during the study period, 3825 contributed ≥1 RT-PCR paired BinaxNOW test. In relation to RT-PCR, the 3-rapid-antigen-test strategy had a sensitivity of 95.9% (95% CI: 93.6-97.5%) and specificity of 98.3% (95% CI: 96.7-99.1%). The sensitivities of the 2- and 1-rapid-antigen-test strategies were 88.8% and 66.8%, and the specificities were 98.5% and 99.4%, respectively. The sensitivity was higher among symptomatic residents and when RT-PCRs were collected before BinaxNOW tests. CONCLUSIONS: We found serial antigen test collection resulted in high diagnostic accuracy. These findings support serial collection for outbreak investigation, screening, and when rapid detection is required (such as intakes or transfers).

Implementing interprofessional video consultations with general practitioners and psychiatrists in correctional facilities in Germany: results from a mixed-methods study.

BACKGROUND: Adequate health care in correctional facilities is often limited by staff shortage, which entails time-consuming consultations with physicians outside of these facilities. Video consultations (VC) have been implemented in many different health care settings and may also be useful in correctional facilities. As part of a pilot project, synchronous VC were implemented in five correctional facilities in Germany in June 2018. The aim of this study was to describe the implementation process from the providers' perspective and to identify factors promoting or inhibiting the implementation process of VC with a focus on interprofessional collaboration between nursing staff and telemedicine physicians. METHODS: As part of the mixed-methods evaluation of the pilot project, site visits to the five correctional facilities were carried out. Nursing staff from the five correctional facilities (n=49) and telemedicine physicians (n=10) were asked to participate in interviews and a questionnaire survey. Interviews were analyzed using qualitative content analysis and questionnaires were evaluated using descriptive statistical methods. The results from both data sources were integrated and discussed in the framework of Normalization Process Theory. RESULTS: Interviews were conducted with 24.5% (n=12) of nursing staff and 20.0% (n=2) of telemedicine physicians, while questionnaires were returned by 22.5% (n=11) of nursing staff and 33.3% (n=3) of telemedicine physicians. VC with general practitioners and psychiatrists were perceived as an additional support during times when physicians were absent from the correctional facilities. Allocating telemedicine physicians to specific correctional facilities might further improve interprofessional collaboration with nursing staff during VC. Inhibiting factors comprised the lack of integrating nursing staff into the implementation process, increased workload, insufficient training and the implementation of VC at an inconvenient time. CONCLUSIONS: To summarize, VC are a promising supplement to face-to-face health care in correctional facilities despite several limitations. These might be compensated by improving interprofessional cooperation and by integrating telemedicine physicians into local health care teams.

Enterprise risk management for automation in correctional facilities with pandemic and other stressors.

Real-time tracking of tool and equipment inventories is a critical function of many organizations and sectors. For prisons and correctional facilities, tracking and monitoring of assets such as cookware, hardware, keys, janitorial equipment, vocational/technical specialty tools, etc., is essential for safety, security, trust, efficiency, education, etc. The performance of automated systems for this purpose can be diminished by a variety of emergent and future sociotechnical factors alone and in combination. This article introduces a methodology for contractor evaluation and selection in acquisition of innovative asset management systems, with an emphasis on evolving system requirements under uncertainty. The methodology features a scenario-based preferences analysis of emergent and future conditions that are disruptive to the performance of the asset-control system. The conditions are across technologies, operating environments, regulations, workforce behaviors, offender behaviors, prices and markets, organizations, cyber threats, etc. The methodology addresses the influence and interaction of the conditions to disrupt system priorities. Examples include: (i) infectious disease disrupting priorities among requirements and (ii)  radio-frequency identification (RFID) and wireless-technology innovations disrupting priorities among stakeholders. The combinations of conditions that most and least matter for the system acquisition are characterized. The methodology constitutes a risk register for monitoring sources of risk to project performance, schedule, and cost throughout the system lifecycle. The results will be of interest to both practitioners and scholars engaged in systems acquisition as the pandemic interacts with other factors to affect risk, uncertainty, and resilience of organizational missions and operations.

Juvenile incarceration in an adult correctional facility as a risk factor for adolescent childrearing?

INTRODUCTION: Recent trends in reproductive rights have contributed to lasting concerns about adolescent childrearing in American society. Beyond being generally unprepared when raising a child, having a child during adolescence is associated with a variety of environmental, social, and psychological consequences for both the parents and the child. It is important to understand the factors contributing to adolescent childrearing. Although research has identified many factors that contribute to adolescent childrearing, a notable gap remains when considering the role of the correctional system and, in particular, the age-specific effects of confining adolescents in adult correctional facilities. METHODS: The current study examined the age-specific effects of time spent in adult correctional facilities from 13 to 34 years of age on childrearing between 14 and 35 years of age using the National Longitudinal Survey of Youth-1997 (NLSY97). The NLSY97 is a nationally representative sample of Males (51%) and Females (49%) born in the United States. Respondents of the NLSY97 were interviewed about life events beginning at age 7 and continued to participate in the study as recently as 2021. RESULTS: The results of the lagged growth curve models suggest that the time spent incarcerated between 13 and 17 years of age heightens the risk of childrearing between 14 and 18 years of age, an effect that is not observed during adulthood. CONCLUSION: Overall, the results suggest that the conditions adolescents are exposed to during incarceration in an adult correctional facility could contribute to a heightened likelihood of adolescent childrearing.

Community Reintegration of Previously Incarcerated Older Adults: Exploratory Insights from a Canadian Community Residential Facility Program.

This paper addresses an immediate gap in knowledge about community reintegration of previously incarcerated older adults. It presents an exploratory case study of a community residential facility program in Ontario, Canada, focusing on the experiences and perspectives of older residents, staff members, and community stakeholders on the community reintegration of previously incarcerated older men. Findings provide insights into the aging-related reintegration issues such as the older men's ability to access health and medical services upon community reentry, the challenges and opportunities of the continuum of support (or lack thereof) to help ease the reintegration process, and stigma and other barriers the older men face as they attempt to access long-term care upon release from correctional institutions. Emergent questions for research, policy, and practice are highlighted and discussed to set an agenda for expanding the thread of inquiry into the community reintegration of previously incarcerated older adults. Future research calls for further investigation into the diversity of experiences (e.g., gender, race/ethnicity, geographical locale) to advance the field of study as it relates to aging and social policy.

Vaccine Effectiveness during Outbreak of COVID-19 Alpha (B.1.1.7) Variant in Men's Correctional Facility, United States.

In April 2021, a COVID-19 outbreak occurred at a correctional facility in rural Virginia, USA. Eighty-four infections were identified among 854 incarcerated persons by facilitywide testing with reverse transcription quantitative PCR (qRT-PCR). We used whole-genome sequencing to link all infections to 2 employees infected with the B.1.1.7α (UK) variant. The relative risk comparing unvaccinated to fully vaccinated persons (mRNA-1273 [Moderna, https://www.modernatx.com]) was 7.8 (95% CI 4.8-12.7), corresponding to a vaccine effectiveness of 87.1% (95% CI 79.0%-92.1%). Average qRT-PCR cycle threshold values were lower, suggesting higher viral loads, among unvaccinated infected than vaccinated cases for the nucleocapsid, envelope, and spike genes. Vaccination was highly effective at preventing SARS-CoV-2 infection in this high-risk setting. This approach can be applied to similar settings to estimate vaccine effectiveness as variants emerge to guide public health strategies during the ongoing pandemic.

Pharmacological interventions for alcohol misuse in correctional settings: A systematic review.

BACKGROUND: The prevalence of alcohol use disorder (AUD) is estimated to be 10 times higher amongst individuals in the criminal justice system than the general population. Alcohol use is also one of the strongest modifiable risk factors for recidivism. One intervention that has been shown to be effective in reducing alcohol consumption in the general population is medication-assisted treatment (MAT), and this systematic review synthesized the existing evidence on MAT for AUD in correctional settings. METHODS: Empirical, peer-reviewed studies on approved medications for AUD in correctional populations were searched in major databases. One hundred sixty-two articles were initially screened and 14 eligible articles were included in the final review. Four articles examined disulfiram, and 10 articles examined naltrexone. RESULTS: The studies on disulfiram were considerably older than those on naltrexone, predating contemporary scientific standards. Disulfiram in combination with substantial contingencies in a supervised setting significantly reduced alcohol-related measures of consumption and recidivism and had acceptable safety and tolerability. All naltrexone studies showed significant reductions in alcohol-related measures, but effects on recidivism were mixed. The naltrexone studies indicated that it was highly acceptable and well tolerated. In addition, offenders receiving naltrexone had significantly greater medication adherence, treatment attendance, and treatment duration than with placebo. CONCLUSIONS: A small number of studies on pharmacological interventions for AUD in the correctional population suggest that MAT is effective in reducing alcohol consumption, although results on recidivism are mixed. On balance, the evidence was more supportive of naltrexone in reducing alcohol-related outcomes than disulfiram and it may also be a more feasible intervention in correctional settings. Further research on MAT to address AUD in correctional populations with larger sample sizes, longer duration, and in combination with behavioral interventions is warranted.

Social support needs of HIV-positive individuals reentering community settings from correctional facilities in Johannesburg, South Africa.

Social networks and social support are important factors in medication adherence among people living with HIV (PLWH). Social networks can provide emotional, logistic, and material support leading to increased overall engagement in care. Certain populations of PLWH may have more limited access to social support, including those reentering community settings from correctional facilities. During periods of incarceration, social connections with family and friends may be frayed, reduced, or lost. This study, conducted in South Africa, explored the role of social support during community reentry among PLWH being released from correctional facilities. We conducted in-depth interviews with 41 community reentrants living with HIV. Qualitative analysis identified the challenges with establishing social support during reentry and the greater need for social support to remain engaged in HIV care in the community compared to in the correctional facility. These findings highlight challenges during community reentry and the importance of social support for these individuals.

Pregnancy and childbirth during incarceration: A qualitative systematic review of lived experiences.

BACKGROUND: Incarcerated individuals who experience pregnancy or childbirth in correctional facilities face unique considerations for obstetric care and consequently are at greater risk of adverse maternal and fetal outcomes. OBJECTIVES: To characterise patient experiences regarding pregnancy and childbirth during incarceration via qualitative synthesis. SEARCH STRATEGY: Medline-OVID, EMBASE, CINAHL, Sociological Abstracts, Social Work Abstracts, Web of Science, Scopus and PsycInfo were systematically searched from inception to 24 December 2020. Supplementary searches were performed using the Scopus database. SELECTION CRITERIA: Only original, peer-reviewed literature was examined. Eligible studies were assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. RESULTS: After screening 4173 original database citations, 24 studies that met inclusion criteria were included and analysed via thematic analysis. The 24 studies included perspectives from 645 female patients who had experienced incarceration, 69 healthcare providers and 70 prison staff. Key patient-reported concerns for the well-being of pregnant individuals during incarceration included mental health challenges, dehumanisation of prenatal care and delivery, lack of privacy, stigma, psychological trauma, lack of emotional support and shackle usage during pregnancy and/or labour. The studies reported a lack of support for patients to access female correctional officers or guards, privacy during intimate examinations, timely medical care and support for breastfeeding. Above all, the psychological trauma of separation from one's newborn after birth was of utmost devastation. CONCLUSIONS: Our systematic review highlights the dire need for accountability and interventions to improve pregnancy and childbirth care for incarcerated individuals. TWEETABLE ABSTRACT: This systematic review describes lived experiences of pregnancy & childbirth during incarceration, including dehumanisation, psychological trauma, and use of shackles.

Munchausen syndrome by proxy (MSBP): a review regarding perpetrators of factitious disorder imposed on another (FDIA).

Munchausen syndrome by proxy (MSBP) is well-known to clinicians, but its usage is discouraged now in favor of other terms placing emphasis on the victim. This study aims to determine the most common characteristics of perpetrators but only in case reports labeled as MSBP, published in PubMed literature in the past 15 years. MSBP has been described as a rare form of abuse due to illness falsification, where the perpetrator usually receives the diagnosis of factitious disorder imposed on another (FDIA). We extracted data from 108 articles, including 81 case reports. Almost all perpetrators were female (91% female, 1% female and male, 7% unreported). Twenty-three cases (28%) had a perpetrator with psychiatric diagnosis: factitious disorder imposed on self (10%), depression (9%), and personality disorders (7%). In more than one-third (36%) there was familial conflict or abuse. Fourteen cases (17%) had perpetrators working in healthcare. The most common type of falsification was induction (74%); however, 15% of cases had more than one type of falsification. The most common outcomes were: separation (37%); no follow-up (22%); imprisonment (14%); death of victim (12%); treatment of the perpetrator (10%); continued living together (4%); and suicide of perpetrator (1%). Recurrence was present in more than three quarters of cases. Our results reiterate that awareness of the most common findings in MSBP allows physicians to identify them in a clinical context.

Barriers and facilitators to attending and being physically active during recreation time among women incarcerated.

BACKGROUND: Most women incarcerated in jail are not physically active and do not attend recreation time (rec-time), a time dedicated to being physically active, outside. The purpose of this study was to determine barriers and facilitators to attending and being physically active during rec-time among women incarcerated in jail. METHODS: We recruited and distributed a cross-sectional questionnaire to 100 women incarcerated at the Coconino County Detention Facility (CCDF) in Flagstaff, Arizona from March to July 2020. Women were asked about their experience with rec-time at CCDF, including if they had ever attended, how often they attended, if they exercised at rec-time, activities they participated in, and facilitators, barriers, and benefits to attend rec-time. RESULTS: Among 99 women who completed the questionnaire, 89% had ever attended rec-time. Most women identified environmental- and health-related facilitators to attending rec-time including enjoying natural light (74%), getting fresh air (83%), a change in environment (62%), and to move around and exercise (72%). Many women indicated environmental-, equipment-, clothing, and motivation-related barriers to attending rec-time. Specifically, women believed there was a lack of equipment (56%) and limited access to proper footwear (49%). CONCLUSIONS: As health and environment are important facilitators and barriers to being physically active among women incarcerated in jail, it is important to identify appropriate environmental and policy interventions to increase the use of rec-time and physical activity. If a correctional facility does not offer rec-time or a similar alternative, one should be established, accessible, and welcoming.

Inclusive health: modeling COVID-19 in correctional facilities and communities.

BACKGROUND: Mass incarceration, commonly associated with overcrowding and inadequate health resources for incarcerated people, creates a fertile environment for the spread of the coronavirus disease 2019 (COVID-19) in U.S. correctional facilities. The exact role that correctional facilities play in enhancing COVID-19 spread and enabling community re-emergence of COVID-19 is unknown. METHODS: We constructed a novel stochastic model of COVID-19 transmission to estimate the impact of correctional facilities, specifically jails and state prisons, for enhancing disease transmission and enabling disease re-emergence in local communities. Using our model, we evaluated scenarios of testing and quarantining infected incarcerated people at 0.0, 0.5, and 1.0 times the rate that occurs for infected people in the community for population sizes of 5, 10, and 20 thousand people. RESULTS: Our results illustrate testing and quarantining an incarcerated population of 800 would reduce the probability of a major outbreak in the local community. In addition, testing and quarantining an incarcerated population would prevent between 10 to 2640 incidences of COVID-19 per year, and annually save up to 2010 disability-adjusted life years, depending on community size. CONCLUSIONS: Managing COVID-19 in correctional facilities is essential to mitigate risks to community health, and thereby stresses the importance of improving the health standards of incarcerated people.

Opioid agonist treatment (OAT) experiences and release plans among federally incarcerated individuals with opioid use disorder (OUD) in Ontario, Canada: a mixed-methods study.

BACKGROUND: Incarcerated populations experience an elevated prevalence of opioid use disorder (OUD). Federal correctional institutions in Canada have increasingly treated OUD among correctional populations via opioid agonist treatment (OAT) - an evidence based pharmacotherapy that works to reduce drug use and related health harms. However, there is limited evidence regarding incarcerated individuals' experiences with institutional-based OAT, as well potential OAT-related community release prospects. This information is important for optimal treatment retention and improved health. To address this knowledge gap, we conducted a longitudinal follow-up study examining OAT-related experiences among federally incarcerated individuals before and after community release. This article focuses on the baseline (pre-release) data. METHODS: This mixed-methods study examined OAT-related experiences and release prospects among n = 46 individuals scheduled for community release, recruited from seven federal prisons located in Ontario, Canada. Participants underwent a comprehensive interviewer-administered on-site assessment, including quantitative and qualitative items. Assessment data was furthermore linked to administrative correctional data. Data were analyzed using thematic qualitative and descriptive quantitative approaches. RESULTS: Participants had complex histories with opioid use including related negative health outcomes. Experiences with institutional OAT were divergent and provision was not standardized; those with OAT engagement pre-admission did not experience many challenges, whereas those initiating OAT during incarceration experienced barriers such as treatment waitlists and adverse process experiences. Most participants expressed a preference for buprenorphine-naloxone over methadone, but described difficulties accessing it. Participants were keen to transition into community-based treatment, yet envisaged prospective barriers and facilitators concerning successful reintegration and treatment continuity. CONCLUSIONS: Major barriers towards the current administration of OAT in federal correctional systems in Canada exist, including extensive waitlists, non-standardized practices, and challenges accessing preferred OAT formulations; this contributes to sub-optimal treatment. Eliminating waitlists, standardizing OAT provision, providing additional OAT options, and more comprehensive release planning may be essential for treatment retention and positive outcomes.
