Health Care and Behavioral Service Use by Medicaid-Enrolled Adults After Release From Incarceration

Prompt access to outpatient care post-incarceration among adults with a history of substance use: Predisposing, enabling, and need-based factors

INTRODUCTION

As expanded Medicaid coverage reduces financial barriers to receiving health care among formerly incarcerated adults, more information is needed to understand the factors that predict prompt use of health care after release among insured adults with a history of substance use. This study's aim was to estimate the associations between characteristics suggested by the Andersen behavioral model of health service use and measures of health care use during the immediate reentry period and in the presence of Medicaid coverage.

METHODS

In this retrospective cohort study, we linked individual-level data from multiple Wisconsin agencies. The sample included individuals aged 18-64 released from a Wisconsin State Correctional Facility between April 2014 and June 2017 to a community in the state who enrolled in Medicaid within one month of release and had a history of substance use. We grouped predictors of outpatient care into variable domains within the Andersen model: predisposing- individual socio-demographic characteristics; enabling characteristics including area-level socio-economic resources, area-level health care supply, and characteristics of the incarceration and release; and need-based- pre-release health conditions. We used a model selection algorithm to select a subset of variable domains and estimated the association between the variables in these domains and two outcomes: any outpatient visit within 30 days of release from a state correctional facility, and receipt of medication for opioid use disorder within 30 days of release.

RESULTS

The size and sign of many of the estimated associations differed for our two outcomes. Race was associated with both outcomes, Black individuals being 12.1 p.p. (95 % CI, 8.7-15.4, P < .001) less likely than White individuals to have an outpatient visit within 30 days of release and 1.3 p.p. (95 % CI, 0.48-2.1, P = .002) less likely to receive MOUD within 30 days of release. Chronic pre-release health conditions were positively associated with the likelihood of post-release health care use.

CONCLUSIONS

Conditional on health insurance coverage, meaningful differences in post-incarceration outpatient care use still exist across adults leaving prison with a history of substance use. These findings can help guide the development of care transition interventions including the prioritization of subgroups that may warrant particular attention.

Substance Use Disorders, Mental Illness, and Health Care Utilization Among Adults With Recent Criminal Legal Involvement

OBJECTIVE

Individuals involved with the criminal legal system have higher rates of mental illness, addiction, and health care utilization. The authors examined whether substance use disorders and mental illness alone or in combination drive health care utilization among those with recent criminal legal involvement.

METHODS

This cross-sectional analysis used nationally representative data from U.S. adults with past-year criminal legal involvement (N=9,039) recorded in the National Survey on Drug Use and Health (2015-2019). Using adjusted negative binomial regression models, the authors estimated relative risks for health care utilization. Primary independent variable categories included neither substance use disorder nor mental illness, substance use disorder only, mental illness only, and both conditions. Health care utilization included emergency department (ED) visits and nights spent in inpatient care.

RESULTS

Relative to neither mental illness nor substance use disorder, mental illness alone was associated with significantly increased acute health care services use: for ED visits, incidence risk ratio (IRR)=1.43 (95% CI=1.18-1.75) and for inpatient stays, IRR=2.14 (95% CI=1.47-3.11). Having both conditions was associated with increased ED visits (IRR=1.62, 95% CI=1.38-1.91) and inpatient stays (IRR=4.16, 95% CI=2.98-5.82). Substance use disorder alone was associated only with higher risk for ED visits compared with neither condition (IRR=1.23, 95% CI=1.01-1.50).

CONCLUSIONS

Mental illness with or without co-occurring substance use disorder is a strong driver of acute health care utilization after interaction with the criminal legal system. Interventions tailored to the unique needs of individuals with mental illness or substance use disorder are needed for those with recent criminal legal involvement.

Incarceration History and Access to and Receipt of Health Care in the US

Importance

People with a history of incarceration may experience barriers in access to and receipt of health care in the US.

Objective

To examine the associations of incarceration history and access to and receipt of care and the contribution of modifiable factors (educational attainment and health insurance coverage) to these associations.

Design, Setting, and Participants

Individuals with and without incarceration history were identified from the 2008 to 2018 National Longitudinal Survey of Youth 1979 cohort. Analyses were conducted from October 2022 to December 2023.

Main Measures and Outcomes

Access to and receipt of health care were measured as self-reported having usual source of care and preventive service use, including physical examination, influenza shot, blood pressure check, blood cholesterol level check, blood glucose level check, dental check, and colorectal, breast, and cervical cancer screenings across multiple panels. To account for the longitudinal study design, we used the inverse probability weighting method with generalized estimating equations to evaluate associations of incarceration history and access to care. Separate multivariable models examining associations between incarceration history and receipt of each preventive service adjusted for sociodemographic factors; sequential models further adjusted for educational attainment and health insurance coverage to examine their contribution to the associations of incarceration history and access to and receipt of health care.

Results

A total of 7963 adults with 41 614 person-years of observation were included in this study; of these, 586 individuals (5.4%) had been incarcerated, with 2800 person-years of observation (4.9%). Compared with people without incarceration history, people with incarceration history had lower percentages of having a usual source of care or receiving preventive services, including physical examinations (69.6% vs 74.1%), blood pressure test (85.6% vs 91.6%), blood cholesterol level test (59.5% vs 72.2%), blood glucose level test (61.4% vs 69.4%), dental check up (51.1% vs 66.0%), and breast (55.0% vs 68.2%) and colorectal cancer screening (65.6% vs 70.3%). With additional adjustment for educational attainment and health insurance, the associations of incarceration history and access to care were attenuated for most measures and remained statistically significant for measures of having a usual source of care, blood cholesterol level test, and dental check up only.

Conclusions and Relevance

The results of this survey study suggest that incarceration history was associated with worse access to and receipt of health care. Educational attainment and health insurance may contribute to these associations. Efforts to improve access to education and health insurance coverage for people with an incarceration history might mitigate disparities in care.
