Health Insurance and Mental Health Treatment Use Among Adults With Criminal Legal Involvement After Medicaid Expansion

Medicaid Expansion and Mortality Among Persons Who Were Formerly Incarcerated

Importance

Since 2014, Medicaid expansion has been implemented in many states across the US, increasing health care access among vulnerable populations, including formerly incarcerated people who experience higher mortality rates than the general population.

Objective

To examine population-level association of Medicaid expansion with postrelease mortality from all causes, unintentional drug overdoses, opioid overdoses, polydrug overdoses, suicides, and homicides among formerly incarcerated people in Rhode Island (RI), which expanded Medicaid, compared with North Carolina (NC), which did not expand Medicaid during the study period.

Design, Setting, and Participants

A cohort study was conducted using incarceration release data from January 1, 2009, to December 31, 2018, linked to death records from January 1, 2009, to December 31, 2019, on individuals released from incarceration in RI and NC. Data analysis was performed from August 20, 2022, to February 15, 2024. Participants included those aged 18 years or older who were released from incarceration. Individuals who were temporarily held during ongoing judicial proceedings, died during incarceration, or not released from incarceration during the study period were excluded.

Exposure

Full Medicaid expansion in RI effective January 1, 2014.

Main Outcomes and Measures

Mortality from all causes, unintentional drug overdoses, unintentional opioid and polydrug overdoses, suicides, and homicides.

Results

Between 2009 and 2018, 17 824 individuals were released from RI prisons (mean [SD] age, 38.39 [10.85] years; 31 512 [89.1%] male) and 160 861 were released from NC prisons (mean [SD] age, 38.28 [10.84] years; 209 021 [87.5%] male). Compared with NC, people who were formerly incarcerated in RI experienced a sustained decrease of 72 per 100 000 person-years (95% CI, -108 to -36 per 100 000 person-years) in all-cause mortality per quarter after Medicaid expansion. Similar decreases were observed in RI in drug overdose deaths (-172 per 100 000 person-years per 6 months; 95% CI, -226 to -117 per 100 000 person-years), including opioid and polydrug overdoses, and homicide deaths (-23 per 100 000 person-years per year; 95% CI, -50 to 4 per 100 000 person-years) after Medicaid expansion. Suicide mortality did not change after Medicaid expansion. After Medicaid expansion in RI, non-Hispanic White individuals experienced 3 times greater sustained decreases in all-cause mortality than all racially minoritized individuals combined, while non-Hispanic Black individuals did not experience any substantial benefits. There was no modification by sex. Individuals aged 30 years or older experienced greater all-cause mortality reduction after Medicaid expansion than those younger than 30 years.

Conclusions and Relevance

Medicaid expansion in RI was associated with a decrease in all-cause, overdose, and homicide mortality among formerly incarcerated people. However, these decreases were most observed among White individuals, while racially minoritized individuals received little to no benefits in the studied outcomes.

Access to Care and Outcomes With the Affordable Care Act for Persons With Criminal Legal Involvement: A Scoping Review

Importance

By expanding health insurance to millions of people in the US, the Patient Protection and Affordable Care Act (ACA) may have important health, economic, and social welfare implications for people with criminal legal involvement-a population with disproportionately high morbidity and mortality rates.

Objective

To scope the literature for studies assessing the association of any provision of the ACA with 5 types of outcomes, including insurance coverage rates, access to care, health outcomes, costs of care, and social welfare outcomes among people with criminal legal involvement.

Evidence Review

The literature search included results from PubMed, CINAHL Complete, APA Psycinfo, Embase, Social Science Database, and Web of Science and was conducted to include articles from January 1, 2014, through December 31, 2023. Only original empirical studies were included, but there were no restrictions on study design.

Findings

Of the 3538 studies initially identified for potential inclusion, the final sample included 19 studies. These 19 studies differed substantially in their definition of criminal legal involvement and units of analysis. The studies also varied with respect to study design, but difference-in-differences methods were used in 10 of the included studies. With respect to outcomes, 100 unique outcomes were identified across the 19 studies, with at least 1 in all 5 outcome categories determined prior to the literature search. Health insurance coverage and access to care were the most frequently studied outcomes. Results for the other 3 outcome categories were mixed, potentially due to heterogeneous definitions of populations, interventions, and outcomes and to limitations in the availability of individual-level datasets that link incarceration data with health-related data.

Conclusions and Relevance

In this scoping review, the ACA was associated with an increase in insurance coverage and a decrease in recidivism rates among people with criminal legal involvement. Future research and data collection are needed to understand more fully health and nonhealth outcomes among people with criminal legal involvement related to the ACA and other health insurance policies-as well as the mechanisms underlying these relationships.

Medicaid Inmate Exclusion Policy and Infectious Diseases Care for Justice-Involved Populations

The Medicaid Inmate Exclusion Policy (MIEP) prohibits using federal funds for ambulatory care services and medications (including for infectious diseases) for incarcerated persons. More than one quarter of states, including California and Massachusetts, have asked the federal government for authority to waive the MIEP. To improve health outcomes and continuation of care, those states seek to cover transitional care services provided to persons in the period before release from incarceration. The Massachusetts Sheriffs' Association, Massachusetts Department of Correction, Executive Office of Health and Human Services, and University of Massachusetts Chan Medical School have collaborated to improve infectious disease healthcare service provision before and after release from incarceration. They seek to provide stakeholders working at the intersection of criminal justice and healthcare with tools to advance Medicaid policy and improve treatment and prevention of infectious diseases for persons in jails and prisons by removing MIEP barriers through Section 1115 waivers.
