"We wish we had the option": a qualitative study of women's perspectives and experiences with contraception in a provincial prison in Ontario, Canada.

BACKGROUND: Evidence suggests that women who are incarcerated desire access to contraception while incarcerated, and that this need is not currently being met. Our objective in this study was to explore the perspectives and experiences of women in prisons regarding contraception and contraception access using data from focus groups with women in a provincial prison. We analyzed focus group data collected in a provincial prison in Ontario, Canada using content analysis and a constructivist epistemology. RESULTS: We conducted three focus groups, each approximately one hour in length. Discussions revolved around (1) knowledge and decision making about contraception, (2) accessing contraception, and (3) ideas for increasing access to contraception in the prison setting. Decision making about contraception was mainly related to concerns about side effects, consistent access to care, impacts on future fertility, and autonomy around decision-making. Participants discussed a wide range of experiences with contraception. Ideas for increasing access to contraception included information sessions, inclusion of discussions about contraception as a component of admission and release planning, and time spent in prison as a crucial juncture for decision-making about contraception. CONCLUSIONS: More qualitative research is needed to better understand the needs of women in prisons related to contraception. The findings of this study suggest that programs should focus on consistency and continuity of access to care, education opportunities, and integration of discussions about contraception into official admission and release procedures.

Chronic Psychotic Disorders and Correctional Involvement: A Population-Based Matched Case-Control Study in Ontario, Canada.

OBJECTIVE: Individuals with chronic psychotic disorders are overrepresented in correctional facilities, but little is known about factors that increase the risk of correctional involvement. The objective of this study was to compare individuals with chronic psychotic disorders who were released from correctional facilities in Ontario to individuals with chronic psychotic disorders but no correctional involvement on sociodemographic, clinical, and prior mental health-related health service utilization characteristics. METHOD: All individuals with chronic psychotic disorders who were released from a provincial correctional facility in Ontario in 2010 were matched (1:2) by age and sex to Ontario residents with chronic psychotic disorders and no correctional involvement. Covariates included sociodemographic (rural residence, marginalization such as residential instability quintile, material deprivation quintile, dependency quintile, and ethnic concentration quintile) and clinical (duration of chronic psychotic disorder and comorbidities) characteristics, and mental health-related health service utilization characteristics (primary care physician, psychiatrist and emergency department visits, and hospitalizations) 1 and 3 years prior to correctional involvement. The association between correctional involvement and prior health service utilization was measured by estimating incidence rate ratios using Poisson and negative-binomial regressions. RESULTS: Individuals with correctional involvement (N = 3,197) lived in neighbourhoods with higher material deprivation and residential instability, and had a shorter duration of illness, and more psychosocial comorbidities (e.g., behavioural issues and depression) than individuals without correctional involvement (N = 6,393). Adjusting for sociodemographic and clinical variables, individuals with correctional involvement had a higher rate of mental health-related primary care physician visits, emergency department visits, and hospitalizations but a lower rate of psychiatrist visits prior to correctional involvement, compared to individuals without correctional involvement. CONCLUSIONS: Despite higher mental health-related comorbidities and higher rates of accessing acute mental health services among individuals with chronic psychotic disorders and correctional involvement, visits to psychiatrists prior to involvement were low.

Opioid toxicity deaths in Black persons who experienced provincial incarceration in Ontario, Canada 2015-2020: A population-based study.

OBJECTIVE: In the context of mass incarceration and the opioid toxicity crisis in North America, there is a lack of data on the burden of opioid toxicity deaths in Black persons who experience incarceration. We aimed to describe absolute and relative opioid toxicity mortality for Black persons who experienced incarceration in Ontario, Canada between 2015 and 2020. METHODS: We linked data for all persons incarcerated in provincial correctional facilities and all persons who died from opioid toxicity in Ontario between 2015 and 2020, and accessed public data on population sizes. We described the characteristics of Black persons who were incarcerated and died from opioid toxicity, and calculated absolute mortality rates, as well as age-standardized mortality rates compared with all persons in Ontario not incarcerated during this period. RESULTS: Between 2015 and 2020, 0.9% (n = 137) of 16,177 Black persons who experienced incarceration died from opioid toxicity in custody or post-release, for an opioid toxicity death rate of 0.207 per 100 person years. In the two weeks post-release, the opioid toxicity death rate was 1.34 per 100 person years. Standardized for age and compared with persons not incarcerated, the mortality ratio (SMR) was 17.8 (95%CI 16.4-23.1) for Black persons who experienced incarceration. CONCLUSIONS: We identified a large, inequitable burden of opioid toxicity death for Black persons who experience incarceration in Ontario, Canada. Work is needed to support access to culturally appropriate prevention and treatment in custody and post-release for persons who are Black, and to prevent incarceration and improve determinants of health.

The impact of COVID-19 on opioid toxicity deaths for people who experience incarceration compared to the general population in Ontario: A whole population data linkage study.

BACKGROUND: To inform preparedness and population health action, we need to understand the effects of COVID-19 on health inequities. In this study, we assess the impact of COVID-19 on opioid toxicity deaths among people who experience incarceration compared to others in the general population in Ontario, Canada. METHODS: We conducted a retrospective cohort study for the period of January 1, 2015 to December 31, 2020. We accessed and linked coronial data on all opioid toxicity deaths in Ontario with correctional data for people aged 18 years and older who were incarcerated in a provincial correctional facility. We used data from the Statistics Canada Census to calculate whole population rates. We used an interrupted time series design and segmented regression to assess for change in the level or rate of increase in deaths due to opioid toxicity coinciding with the COVID-19 pandemic. We compared the impact of COVID-19 on the opioid toxicity death rates for people exposed and not exposed to incarceration. RESULTS: Rates of opioid toxicity death increased with a linear positive slope in both persons exposed to incarceration and those not exposed over the study period. The start of COVID-19 measures coincided with a marked upward shift in the trend lines with modification of the effect of COVID-19 by both sex and exposure to incarceration. For persons exposed to incarceration, the risk ratio (RR) was 1.50 (95%CI 1.35-1.69) for males and 1.21 (95%CI 1.06-1.42) for females, and for persons not exposed to incarceration, the RR was 1.25 (95%CI 1.13-1.38) for males and not significant for females. CONCLUSIONS: COVID-19 substantially exacerbated the risk of opioid toxicity death, impacting males and females who experienced incarceration more than those who had not, with an immediate stepwise increase in risk but no change in the rate of increase of risk over time. Public health work, including pandemic preparedness, should consider the specific needs and circumstances of people who experience incarceration.

The health impacts of the COVID-19 pandemic on adults who experience imprisonment globally: A mixed methods systematic review.

BACKGROUND: The prison setting and health status of people who experience imprisonment increase the risks of COVID-19 infection and sequelae, and other health impacts of the COVID-19 pandemic. OBJECTIVES: To conduct a mixed methods systematic review on the impacts of the COVID-19 pandemic on the health of people who experience imprisonment. DATA SOURCES: We searched Medline, PsycINFO, Embase, the Cochrane Library, Social Sciences Abstracts, CINAHL, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Sociology Database, Coronavirus Research Database, ERIC, Proquest Dissertations and Theses, Web of Science, and Scopus in October 2021. We reviewed reference lists for included studies. STUDY ELIGIBILITY CRITERIA: Original research conducted in or after December 2019 on health impacts of the COVID-19 pandemic on adults in prisons or within three months of release. STUDY APPRAISAL AND SYNTHESIS METHODS: We used the Joanna Briggs Institute's Critical Appraisal Checklist for Qualitative Research for qualitative studies and the Joanna Briggs Institute's Critical Appraisal Checklist for Studies Reporting Prevalence Data for quantitative studies. We qualitized quantitative data and extracted qualitative data, coded data, and collated similar data into categories. RESULTS: We identified 62 studies. People in prisons had disproportionately high rates of COVID-19 infection and COVID-19 mortality. During the pandemic, all-cause mortality worsened, access to health care and other services worsened, and there were major impacts on mental wellbeing and on relationships with family and staff. There was limited evidence regarding key primary and secondary prevention strategies. LIMITATIONS: Our search was limited to databases. As the COVID-19 pandemic is ongoing, more evidence will emerge. CONCLUSIONS: Prisons and people who experience imprisonment should be prioritized for COVID-19 response and recovery efforts, and an explicit focus on prisons is needed for ongoing public health work including emergency preparedness. PROSPERO REGISTRATION NUMBER: 239324.

Buprenorphine/naloxone access for people with opioid use disorder in correctional facilities: taking steps to support knowledge translation.

People with opioid use disorders are overrepresented in correctional facilities, and are at high risk of opioid overdose. Despite the fact that buprenorphine/naloxone is the first line treatment for people with opioid use disorder, there are often institutional, clinical, and logistical barriers to buprenorphine/naloxone initiation in correctional facilities. Guided by the knowledge-to-action framework, this knowledge translation project focused on synthesizing knowledge and developing a tool for buprenorphine/naloxone initiation that was tailored to correctional facilities, including jails. This information and tool can be used to support buprenorphine/naloxone access for people in correctional facilities, in parallel with other efforts to address barriers to treatment initiation in correctional facilities.

Intellectual/developmental disabilities among people incarcerated in federal correctional facilities in Ontario, Canada: Examining prevalence, health and correctional characteristics.

BACKGROUND: There is little research with people who experience intellectual/developmental disabilities and imprisonment. METHODS: The study linked health and correctional data to examine prevalence of intellectual/developmental disabilities and health and correctional characteristics among adults experiencing their first federal incarceration between 1 January 2002 and 31 December 2011 (n = 9278) and two non-incarcerated groups (n = 10,086,802). RESULTS: The prevalence of intellectual/developmental disabilities was 2.1% in the incarcerated group and 0.9% in the non-incarcerated group. Before incarceration, those with, versus without, intellectual/developmental disabilities were at greater risk of traumatic brain injury, mental illness, and substance use disorders. While incarcerated, those with intellectual/developmental disabilities were more likely to incur serious institutional disciplinary charges. Post-incarceration, persons with intellectual/developmental disabilities were at greater risk of emergency department visits, and psychiatric and acute hospitalizations, than the non-incarcerated groups. CONCLUSIONS: People with intellectual/developmental disabilities are overrepresented in Canadian federal correctional institutions. The authors offer strategies to support people prior to, during, and post-incarceration.

Health Care Costs of Individuals With Chronic Psychotic Disorders Who Experience Incarceration in Ontario.

OBJECTIVE: Little is known about the health care costs of individuals with chronic psychotic disorders who experience incarceration. This study sought to address this knowledge gap. METHODS: The authors analyzed linked 2007-2010 correctional and administrative health care data on sex- and age-matched individuals with chronic psychotic disorders with and without known incarceration in prison for up to 2 years in the Ontario correctional system. Mean 1-year health care costs (overall and by sex) in the year before incarceration (when release occurred in 2010) were estimated from third-party payer data and compared between the two groups. Costs were calculated in 2018 Canadian dollars. RESULTS: Individuals who experienced incarceration (N=3,197) had mean 1-year costs of $15,728 in the year before incarceration, whereas those who did not (N=6,393) had 1-year costs of $11,588. This difference was mostly due to costs arising from psychiatric hospitalizations, emergency department visits, and physician services. The main factors associated with the difference were incarceration in the following year (increase of $4,827, p<0.001), being age 18-29 years compared with ages 30-39 or 40-49 (increase of $4,448 and $4,218, respectively, p<0.001), and chronic psychotic disorder duration of 1-2 years compared with ≤1 year duration (increase of $6,812, p=0.004). Women who experienced incarceration had higher costs than incarcerated men ($20,648 vs. $14,763). CONCLUSIONS: Individuals with chronic psychotic disorders who experienced incarceration had higher health care costs than comparable individuals who did not. These higher health care costs may signal the need for interventions and policies that help individuals with psychotic disorders avoid criminal justice system involvement.

Health Status of Females Who Experience Incarceration: A Population-Based Retrospective Cohort Study.

Background: People who experience incarceration have poor health across a variety of indicators, but we lack population-level data on the health of females in particular. We examined the health status of females released from provincial prison, and compared their data with data for males released from provincial prison and females in the general population in Ontario, Canada in 2010. Methods: We conducted a retrospective cohort study using linked correctional and health administrative data. We compared sociodemographic data, morbidity, mortality, and use of health care for (1) females released from provincial prison in 2010, (2) males released from provincial prison in 2010, and (3) age-matched females in the general population. Results: Females in the incarceration group (N = 6,107) were more likely to have higher morbidity and specific psychiatric conditions compared with the male incarceration group (N = 42,754) and the female general population group (N = 24,428). Their mortality rate postrelease was several times higher than that for the female general population group. They used primary care more often than both comparator groups across all time periods, and they used emergency departments more often compared with the female general population group and in most periods postrelease compared with the male incarceration group. They also tended to have higher rates of medical-surgical and psychiatric hospitalization. Conclusion: Females who experience incarceration have worse health overall than males who experience incarceration and females in the general population. Efforts should be made to reform programs and policies in the criminal justice and health care systems to support and promote health for females who experience incarceration.

Prevalence and Predictors of Reincarceration after Correctional Center Release: A Population-based Comparison of Individuals with and without Schizophrenia in Ontario, Canada: Prévalence et prédicteurs de la réincarcération après la libération d'un centre correctionnel : une comparaison dans la population-de personnes souffrant ou non de schizophrénie en Ontario, Canada.

OBJECTIVES: Individuals with schizophrenia are overrepresented in correctional facilities relative to their population-based prevalence. The purpose of this study was to determine the rate and predictors of reincarceration of individuals with schizophrenia after release from correctional facilities. METHODS: This was a retrospective cohort study that included all people released from Ontario's provincial correctional facilities from January 1 to December 31, 2010. Individuals with schizophrenia were identified using a population-based algorithm. The primary outcome was time to reincarceration. Covariates included sociodemographic characteristics (age, sex, neighborhood income quintile, urban/rural residence), health service utilization (primary care physician visits, psychiatrist visits, psychiatric and nonpsychiatric hospitalizations, emergency department visits), and other clinical comorbidity. Survival analysis was used to examine the association between schizophrenia and reincarceration. RESULTS: Among 46,928 individuals, N = 3,237 (7%) had a diagnosis of schizophrenia. Approximately 67.5% of these individuals were reincarcerated within 5 years following their first release in 2010, compared to 58.8% of individuals without schizophrenia. Individuals with schizophrenia were 40% (HR = 1.39, 95% CI, 1.33 to 1.45) more likely to be reincarcerated following release than the control group after adjusting for demographic characteristics. This association reduced to 8% (HR = 1.08, 95% CI,1.03 to 1.14) after adjusting for prior health service utilization, prior correctional involvement, and comorbidities. CONCLUSION: Individuals with schizophrenia were more likely to experience reincarceration after release from correctional facilities. This risk is partly explained by prior correctional involvement, health service utilization, and comorbidities. Future research should focus on risk factors predicting the higher reincarceration rate and interventions to reduce correctional involvement.

The impact of a Housing First intervention and health-related risk factors on incarceration among people with experiences of homelessness and mental illness in Canada.

OBJECTIVE: To examine the effect of a Housing First (HF) intervention and health-related risk factors on incarceration among adults with experiences of homelessness and mental illness. METHODS: Participants (N = 508) were recruited at the Toronto site of the At Home/Chez Soi study. The outcome was incarceration in Ontario from 2009 to 2014. Exposures were intervention group (HF vs. treatment as usual), Axis I mental health diagnoses, emergency department (ED) visit, and history of traumatic brain injury (TBI). Logistic regression was used to examine the association between exposures and incarceration. RESULTS: Of 508 participants, 220 (43.3%) were incarcerated at least once during the study period. Among those incarcerated, 81.9% were male, 52.7% had been diagnosed with alcohol dependence/abuse, 60.9% had been diagnosed with substance dependence/abuse, 65.1% reported having visited an ED within the last 6 months, and 66.4% had a history of TBI. After adjusting for demographic covariates, substance dependence/abuse (aOR: 2.06; 95% CI: 1.40, 3.03), alcohol dependence/abuse (aOR: 1.52, 95% CI: 1.04, 2.22), ED visit (aOR: 1.54; 95% CI: 1.02, 2.32), and history of TBI (aOR: 2.60; 95% CI: 1.75, 3.85) were associated with incarceration. We found no significant effect of the HF intervention on incarceration outcome (aOR: 1.08; 95% CI: 0.76, 1.55). CONCLUSIONS: Among adults with experiences of homelessness and severe mental illness, those with substance and alcohol dependence/abuse disorders, history of TBI, and recent ED visits were at increased odds of incarceration. Strategies are needed to prevent and reduce incarceration for this population, including treatment of mental illness in the community.

RéSUMé: OBJECTIF: Examiner l'effet d'une intervention de Logement d'abord (LD) et de facteurs de risque liés à la santé sur l'incarcération d'adultes ayant vécu des épisodes de sans-abrisme et de maladie mentale. MéTHODE: Les participants (N = 508) ont été recrutés sur le site torontois de l'étude At Home/Chez-Soi. L'issue à l'étude était l'incarcération en Ontario entre 2009 et 2014. Les expositions étaient le groupe d'intervention (LD vs. traitement habituel), les diagnostics de troubles de santé mentale de l'axe I, les visites aux services d'urgence (SU) et les antécédents de traumatisme cranio-cérébral (TCC). Nous avons procédé par régression logistique pour examiner l'association entre les expositions et l'incarcération. RéSULTATS: Sur 508 participants, 220 (43,3 %) avaient été incarcérés au moins une fois durant la période de l'étude. Chez les personnes incarcérées, 81,9 % étaient des hommes, 52,7 % avaient un diagnostic de dépendance à l'alcool ou d'abus d'alcool, 60,9 % avaient un diagnostic de dépendance à des substances ou d'abus de substances, 65,1 % ont dit avoir visité les SU au cours des 6 mois antérieurs, et 66,4 % avaient des antécédents de TCC. Après ajustement en fonction des covariables démographiques, la dépendance aux substances/l'abus de substances (rapport de cotes ajusté [RCa] : 2,06; IC de 95 % : 1,40, 3,03), la dépendance à l'alcool/l'abus d'alcool (RCa : 1,52, IC de 95 % : 1,04, 2,22), les visites aux SU (RCa : 1,54; IC de 95 % : 1,02, 2,32) et les antécédents de TCC (RCa : 2,60; IC de 95 % : 1,75, 3,85) étaient associés à l'incarcération. Nous n'avons observé aucun effet significatif de l'intervention de LD sur l'issue d'incarcération (RCa : 1,08; IC de 95 % : 0,76, 1,55). CONCLUSIONS: Chez les adultes ayant vécu des épisodes de sans-abrisme et de maladie mentale grave, ceux qui avaient des troubles de dépendance/d'abus de substances et d'alcool, des antécédents de TCC et qui avaient visité les SU récemment présentaient une probabilité accrue d'incarcération. Il faut des stratégies pour prévenir et réduire l'incarcération dans cette population, y compris des stratégies de traitement des maladies mentales hors du milieu carcéral.

Quality of Antenatal Care for Women Who Experience Imprisonment in Ontario, Canada.

Importance: Women who experience imprisonment have high morbidity and an increased risk of adverse pregnancy outcomes. Antenatal care could modify pregnancy-related risks, but there is a lack of evidence regarding antenatal care in this population. Objectives: To examine antenatal care quality indicators for women who experience imprisonment and to compare these data with data for the general population. Design, Setting, and Participants: This population-based, retrospective cohort study used linked correctional and health administrative data from women released from provincial prison in Ontario, Canada, in 2010 and women in the general population with deliveries at 20 weeks' gestation or greater from January 1, 2005, to December 31, 2015. Data analysis was performed from January 1, 2017, to May 4, 2020. Exposures: Pregnancies in women with time in prison during pregnancy (prison pregnancies), pregnancies in women with time in prison but not while pregnant (prison control pregnancies), and pregnancies in women in the general population (general population pregnancies). Main Outcomes and Measures: Antenatal care quality indicators: first-trimester visit, first-trimester ultrasonography, and 8 or more antenatal care visits. Results: A total of 626 prison pregnancies in 529 women (mean [SD] age, 26.6 [5.4] years), 2327 prison control pregnancies in 1570 women (mean [SD] age, 26.2 [5.4] years), and 1 308 879 general population pregnancies in 884 063 women (mean [SD] age, 30.3 [5.3] years) were studied. Of 626 prison pregnancies, 193 women (30.8%; 95% CI, 27.1%-34.6%) had a first-trimester visit, 272 (48.4%; 95% CI, 44.4%-52.4%) had at least 8 antenatal care visits, and 209 (34.6%; 95% CI, 31.0%-38.4%) received first-trimester ultrasonography. In 2327 prison control pregnancies, 1106 women (47.5%; 95% CI, 45.3%-49.8%) had a first-trimester visit, 1356 (59.2%; 95% CI, 56.9%-61.4%) had 8 or more antenatal care visits, and 893 (38.5%; 95% CI, 36.4%-40.6%) received first-trimester ultrasonography. Compared with 1 308 879 general population pregnancies, the odds of antenatal care were lower for the first-trimester visit (odds ratios [ORs], 0.11 [95% CI, 0.09-0.13] in prison pregnancies and 0.23 [95% CI, 0.21-0.25] in prison control pregnancies), 8 or more antenatal care visits (ORs, 0.16 [95% CI, 0.14-0.19] in prison pregnancies and 0.25 [95% CI, 0.23-0.28] in prison control pregnancies), and first-trimester ultrasonography (ORs, 0.43 [95% CI, 0.36-0.50] in prison pregnancies and 0.51 [95% CI, 0.46-0.55] in prison control pregnancies). Conclusions and Relevance: This study found that women who experienced imprisonment were substantially less likely to receive adequate antenatal care than were women in the general population whether or not they were in prison during pregnancy. Efforts are needed to improve antenatal care for this population both in prison and in the community.

"When you first walk out the gates where do [you] go?": Barriers and opportunities to achieving continuity of health care at the time of release from a provincial jail in Ontario.

We aimed to explore continuity of health care and health barriers, facilitators, and opportunities for people at the time of release from a provincial correctional facility in Ontario, Canada. We conducted focus groups in community-based organizations in a city in Ontario, Canada: a men's homeless shelter, a mental health service organization, and a social service agency with programs for people with substance use disorders. We included adults who spoke English well enough to participate in the discussion and who had been released from the provincial correctional facility in the previous year. We conducted three focus groups with 18 total participants. Participants had complex health needs on release, including ongoing physical and psychological impacts of time in custody. They identified lack of access to high quality health care; lack of housing, employment, social services, and social supports; and discrimination on the basis of incarceration history as barriers to health on release. Access to health care, housing, social services, and social supports all facilitated health on release. To address health needs on release, participants suggested providing health information in jail, improving discharge planning, and developing accessible clinics in the community. This pilot study identified opportunities to support health at the time of release from jail, including delivery of programs in jail, linkage with and development of programs in the community, and efforts to support structural changes to prevent and address discrimination. These data will inform ongoing work to support health and continuity of care on release from a provincial correctional facility.

Improving Health and Healthcare Access for People Who Experience Imprisonment in Ontario.

People who experience imprisonment have worse health status than other Ontarians - about 40% lack access to primary care in the community, and the period after release from prison is associated with high risks of adverse health outcomes. Population-based correctional and health administrative data suggest that access to quality healthcare in prison and in the community needs to improve if we are to improve population health and deliver on healthcare obligations to people experiencing imprisonment.

Infant and Maternal Outcomes for Women Who Experience Imprisonment in Ontario, Canada: A Retrospective Cohort Study.

OBJECTIVE: To describe the population-level risk of infant and maternal outcomes for women who experience imprisonment and compare outcomes with the general population. METHODS: We conducted a retrospective cohort study. We used linked correctional and health data for women released from provincial prisons in 2010. We defined three exposure groups for Ontario singleton deliveries from 2005-2015: deliveries to women who were in prison during pregnancy but not necessarily for delivery, prison pregnancies; deliveries to women who had been in prison but not while pregnant, prison controls; and general population deliveries. We compared groups using generalized estimating equations. Primary outcomes were preterm birth, low birth weight, and small for gestational age birth weight. Secondary outcomes included NICU admission, neonatal abstinence syndrome, placental abruption, and preterm prelabour rupture of membranes. RESULTS: In prison pregnancies (n = 544) and prison controls (n = 2156), respectively, preterm birth risk was 15.5% and 12.5%, low birth weight risk was 13.0% and 11.6%, and small for gestational age birth weight risk was 18.1% and 19.2%. Adjusted for maternal age and parity and compared with general population deliveries (N = 1 284 949), odds ratios were increased for prison pregnancies and prison controls, respectively, at 2.7 (95% CI 2.2-3.4) and 2.1 (95% CI 1.9-2.4) for preterm birth, 3.1 (95% CI 2.4-3.9) and 2.7 (95% CI 2.3-3.1) for low birth weight, and 1.6 (95% CI 1.3-2.1) and 1.8 (95% CI 1.6-2.0) for small for gestational age birth weight. CONCLUSION: There is an increased risk of adverse infant outcomes in women who experience imprisonment compared with the general population, whether they are in prison during pregnancy or not.

Thirty-day readmission after medical-surgical hospitalization for people who experience imprisonment in Ontario, Canada: A retrospective cohort study.

We aimed to compare 30-day readmission after medical-surgical hospitalization for people who experience imprisonment and matched people in the general population in Ontario, Canada. We used linked population-based correctional and health administrative data. Of people released from Ontario prisons in 2010, we identified those with at least one medical or surgical hospitalization between 2005 and 2015 while they were in prison or within 6 months after release. For those with multiple eligible hospitalizations, we randomly selected one hospitalization. We stratified people by whether they were in prison or recently released from prison at the time of hospital discharge. We matched each person with a person in the general population based on age, sex, hospitalization case mix group, and hospital discharge year. Our primary outcome was 30-day hospital readmission. We included 262 hospitalizations for people in prison and 1,268 hospitalizations for people recently released from prison. Readmission rates were 7.7% (95%CI 4.4-10.9) for people in prison and 6.9% (95%CI 5.5-8.3) for people recently released from prison. Compared with matched people in the general population, the unadjusted HR was 0.72 (95%CI 0.41-1.27) for people in prison and 0.78 (95%CI 0.60-1.02) for people recently released from prison. Adjusted for baseline morbidity and social status, hospitalization characteristics, and post-discharge health care use, the HR for 30-day readmission was 0.74 (95%CI 0.40-1.37) for people in prison and 0.48 (95%CI 0.36-0.63) for people recently released from prison. In conclusion, people recently released from prison had relatively low rates of readmission. Research is needed to elucidate reasons for lower readmission to ensure care quality and access.

Emergency department use in people who experience imprisonment in Ontario, Canada.

OBJECTIVES: The aims of this study were to describe emergency department (ED) utilization by people in provincial prison and on release, and to compare with ED utilization for the general population. METHODS: We linked correctional and health administrative data for people released from provincial prison in Ontario in 2010. We matched each person by age and sex with four people in the general population. We compared ED utilization rates using generalized estimating equations, by sex and for high urgency and ambulatory care sensitive conditions. RESULTS: People who experienced imprisonment (N = 48,861) had higher ED utilization rates compared with the general population (N = 195,444), with rate ratios of 3.2 (95% CI 3.0-4.4) for men and 6.5 (95% CI 5.6-7.5) for women in prison and a range of rate ratios between 3.1 and 7.7 for men and 4.2 and 8.8 for women over the 2 years after release. Most ED visits were high urgency, and between 1.0% and 5.1% of visits were for ambulatory care sensitive conditions. ED utilization rates increased on release from prison. CONCLUSIONS: People experiencing imprisonment in Ontario have higher ED utilization compared with matched people in the general population, primarily for urgent issues, and particularly in women and in the week after release. Providing high-quality ED care and implementing prison- and ED-based interventions could improve health for this population and prevent the need for ED use.

90-90-90 for everyone?: Access to HIV care and treatment for people with HIV who experience imprisonment in Ontario, Canada.

We examined HIV care and treatment in prison and after release for people with HIV in Ontario, Canada, and compared HIV care and treatment with the general population. We used administrative data to identify people with HIV released from provincial prison in 2010 and in the general population. We calculated the proportion of people with HIV who accessed HIV care in prison. We compared HIV care use between people with HIV on prison release and in the general population. We estimated the proportion of people with HIV on antiretroviral therapy in prison as the ratio of the average numbers of people prescribed antiretroviral therapy in prison in 2009/2010 and people with HIV in prison in January 2010. We compared the proportion of people with HIV on public drug benefits that filled an antiretroviral therapy prescription within 6 months for people postrelease and in the general population. Of 344 people with HIV on prison admission, 34.0% received HIV care in prison. Over 1 year, 63.6% of 330 people with HIV on prison release and 67.7% of 15,819 people with HIV in the general population accessed HIV care (p = 0.118), and 43.3% of people with HIV on prison release and 55.2% of people with HIV in the general population had 2 or more HIV care visits (p < 0.001). In prison, 52.4% of people with HIV (39.5/75.4) were on antiretroviral therapy. Of those accessing drug benefits, 60.1% of 226 people with HIV on prison release and 79.6% of 7458 people with HIV in the general population claimed an antiretroviral therapy prescription within 6 months (p < 0.001). Access to HIV care and treatment were suboptimal in prison, and sustained HIV care and treatment were worse for people post-release compared to the general population. Interventions are needed to support HIV care for this population.
