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

Data linkage studies of primary care utilisation after release from prison: a scoping review

BACKGROUND

Primary care plays a central role in most, if not all, health care systems including the care of vulnerable populations such as people who have been incarcerated. Studies linking incarceration records to health care data can improve understanding about health care access following release from prison. This review maps evidence from data-linkage studies about primary care use after prison release.

METHODS

The framework by Arksey and O'Malley and guidance by the Joanna Briggs Institute (JBI) were used in this review. This scoping review followed methods published in a study protocol. Searches were performed (January 2012-March 2023) in MEDLINE, EMBASE and Web of Science Core Collection using key-terms relating to two areas: (i) people who have been incarcerated and (ii) primary care. Using eligibility criteria, two authors independently screened publication titles and abstracts (step 1), and subsequently, screened full text publications (step 2). Discrepancies were resolved with a third author. Two authors independently charted data from included publications. Findings were mapped by methodology, key findings and gaps in research.

RESULTS

The database searches generated 1,050 publications which were screened by title and abstract. Following this, publications were fully screened (n = 63 reviewer 1 and n = 87 reviewer 2), leading to the inclusion of 17 publications. Among the included studies, primary care use after prison release was variable. Early contact with primary care services after prison release (e.g. first month) was positively associated with an increased health service use, but an investigation found that a large proportion of individuals did not access primary care during the first month. The quality of care was found to be largely inadequate (measured continuity of care) for moderate multimorbidity. There were lower levels of colorectal and breast cancer screening among people released from custody. The review identified studies of enhanced primary care programmes for individuals following release from prison, with studies reporting a reduction in reincarceration and criminal justice system costs.

CONCLUSIONS

This review has suggested mixed evidence regarding primary care use after prison release and has highlighted challenges and areas of suboptimal care. Further research has been discussed in relation to the scoping review findings.

Health status and health-care utilization among men recently released from a superjail: a matched prospective cohort study

PURPOSE

Continuity of care and access to primary care have been identified as important contributors to improved health outcomes and reduced reincarceration among people who are justice-involved. While the disproportionate burden of health concerns among incarcerated populations is well documented, less is known about their health service utilization, limiting the potential for effective improvements to current policy and practice. This study aims to examine health status and health care utilization among men recently released from a superjail in a large metropolitan area to better understand patterns of use, risk factors and facilitators.

DESIGN/METHODOLOGY/APPROACH

Participants included adult men (n = 106) matched to a general population group (n = 530) in Ontario, Canada, linked to medical records (88.5% linkage) to examine baseline health status and health utilization three-months post-release. The authors compared differences between the groups in baseline health conditions and estimated the risk of emergency department, primary care, inpatient hospitalization and specialist ambulatory care visits.

FINDINGS

Superjail participants had a significantly higher prevalence of respiratory conditions, mental illness, substance use and injuries. Substance use was a significant risk factor for all types of visits and emergency department visits were over three times higher among superjail participants.

ORIGINALITY/VALUE

This empirical case is illustrative of an emerging phenomenon in some regions of the world where emergency departments serve as de facto "walk-in clinics" for those with criminal justice involvement. Strategic approaches to health services are required to meet the complex social and health needs and disparities in access to care experienced by men released from custody.

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.
