High prevalence of hepatitis C virus infection among incarcerated persons: Results from the Louisiana Hepatitis C Elimination Plan's opt-out testing program in prisons.

In the United States, modelling studies suggest a high prevalence of hepatitis C virus (HCV) infection in incarcerated populations. However, limited HCV testing has been conducted in prisons. Through the Louisiana Hepatitis C Elimination Plan, persons incarcerated in the eight state prisons were offered HCV testing from 20 September 2019 to 14 July 2022, and facility entry/exit HCV testing was introduced. Multivariable logistic regression was used to evaluate associations with HCV antibody (anti-HCV) positivity and viremia. Of 17,231 persons in the eight state prisons screened for anti-HCV, 95.1% were male, 66.7% were 30-57 years old, 3% were living with HIV, 68.2% were Black and 2904 (16.9%) were anti-HCV positive. HCV RNA was detected in 69.3% of anti-HCV positive individuals tested. In the multivariable model, anti-HCV positivity was associated with older age including those 30-57 (odds ratio [OR] 3.53, 95% confidence interval [CI] 2.96-4.20) and those ≥58 (OR 10.43, 95% CI 8.66-12.55) as compared to those ≤29 years of age, living with HIV (OR 1.68, 95% CI 1.36-2.07), hepatitis B (OR 1.83, 95% CI 1.25-2.69) and syphilis (OR 1.51, 95% CI 1.23-1.86). HCV viremia was associated with male sex (OR 1.89, 95% CI 1.36-2.63) and Black race (OR 1.42, 95% CI 1.20-1.68). HCV prevalence was high in the state prisons in Louisiana compared to community estimates. To the extent that Louisiana is representative, to eliminate HCV in the United States, it will be important for incarcerated persons to have access to HCV testing and treatment.

Reported xylazine exposure highly associated with overdose outcomes in a rapid community assessment among people who inject drugs in Baltimore.

BACKGROUND: Addressing xylazine harms are now a critical harm reduction priority, but relatively little epidemiological information exists to determine prevalence, magnitude, and correlates of xylazine use or related outcomes. METHODS: We conducted a rapid behavioral survey among people who inject drugs (n = 96) in Baltimore November-December 2022. Using a novel indicator of self-reported presumed xylazine effects, we examined prevalence and sociodemographic correlates of past year presumed xylazine effects and association with overdose and wound-related outcomes. Chi-square and descriptive statistics were used to examine bivariate associations overall and separately for those who reported xylazine by name and by reported fentanyl use frequency. RESULTS: Almost two-thirds (61.5%) reported experiencing xylazine effects. There were no differences by socio-demographics, but xylazine effects were more commonly reported among those who reported injecting alone (66% vs 38%%, p < 0.007) and daily fentanyl use (47% vs 24% p < 0.003). Those reporting xylazine exposure was three times as likely to report overdose (32% vs 11%, p < 0.03) and twice as likely to have used naloxone (78% vs 46%, p < 0.003). They also more commonly reported knowing someone who died of an overdose (92% vs 76%, p < 0.09) and to report an abscess requiring medical attention (36% vs 19%, p < 0.80). These associations were higher among respondents who specifically named xylazine and those who used fentanyl more frequently, but fentanyl frequency did not fully explain the heightened associations with xylazine effects. CONCLUSIONS: This study provides insight into the scope of xylazine exposure and associated health concerns among community-based PWID and suggests measures that may be instrumental for urgently needed research.

Examining Pre-Release Interventions on HIV Outcomes 12 Months After Release from Louisiana State Corrections.

Louisiana has the highest proportion of people living with HIV (PLWH) in state prison custody. Linkage to care programs minimize odds of HIV care drop-off after release. Louisiana has two pre-release linkage to HIV care programs, one implemented through Louisiana Medicaid and another through the Office of Public Health. We conducted a retrospective cohort study of PLWH released from Louisiana corrections from January 1, 2017 to December 31, 2019. We compared HIV care continuum outcomes within 12 months after release between intervention groups (received any vs. no intervention) using two proportion z-tests and multivariable logistic regression. Of 681 people, 389 (57.1%) were not released from a state prison facility and thus not eligible to receive interventions, 252 (37%) received any intervention, and 228 (33.5%) achieved viral suppression. Linkage to care within 30 days was significantly higher in people who received any intervention (v. no intervention, p = .0142). Receiving any intervention was associated with higher odds of attaining all continuum steps, though only significantly for linkage to care (AOR = 1.592, p = .0083). We also found differences in outcomes by sex, race, age, urbanicity of the return parish (county), and Medicaid enrollment between intervention groups. Receiving any intervention increased the odds of achieving HIV care outcomes, and was significantly impactful at improving care linkage. Interventions must be improved to enhance long-term post-release HIV care continuity and eliminate disparities in care outcomes.

Reducing Opioid Analgesic Prescribing in Dentistry Through Prescribing Defaults: A Cluster-Randomized Controlled Trial.

OBJECTIVE: To determine the effect of a uniform, reduced, default dispense quantity for new opioid analgesic prescriptions on the quantity of opioids prescribed in dentistry practices. METHODS: We conducted a cluster-randomized controlled trial within a health system in the Bronx, NY, USA. We randomly assigned three dentistry sites to a 10-tablet default, a 5-tablet default, or no change (control). The primary outcome was the quantity of opioid analgesics prescribed in the new prescription. Secondary outcomes were opioid analgesic reorders and health service utilization within 30 days after the new prescription. We analyzed outcomes from 6 months before implementation through 18 months after implementation. RESULTS: Overall, 6,309 patients received a new prescription. Compared with the control site, patients at the 10-tablet-default site had a significantly larger change in prescriptions for 10 tablets or fewer (38.7 percentage points; confidence interval [CI]: 11.5 to 66.0), lower number of tablets prescribed (-3.3 tablets; CI: -5.9 to -0.7), and lower morphine milligram equivalents (MME) prescribed (-14.1 MME; CI: -27.8 to -0.4), which persisted in the 30 days after the new prescription despite a higher percentage of reorders (3.3 percentage points; CI: 0.2 to 6.4). Compared with the control site, patients at the 5-tablet-default site did not have a significant difference in any outcomes except for a significantly higher percentage of reorders (2.6 percentage points; CI: 0.2 to 4.9). CONCLUSIONS: Our findings further support the efficacy of strategies that lower default dispense quantities, although they indicate that caution is warranted in the selection of the default. TRIAL REGISTRATION: ClinicalTrials.org ID: NCT03030469.

Characteristics and health service use of Medicaid-insured individuals filling naloxone under a standing order in Louisiana.

BACKGROUND: Naloxone distribution is a key intervention to reduce opioid overdose deaths. On January 23, 2017, Louisiana implemented a standing order that permits pharmacies to dispense naloxone to patients without a patient-specific prescription. OBJECTIVES: To examine the characteristics and health service use of Louisiana Medicaid members filling naloxone under the standing order. METHODS: We conducted a retrospective cohort study of Louisiana Medicaid members from January 23, 2017 to December 31, 2019. We extracted fee-for-service claims and managed care encounters for naloxone dispensed under the standing order. RESULTS: Overall, there were 2053 naloxone fills by 1912 unique individuals. The total number of naloxone fills increased from 22 in 2017 to 1218 in 2019. Most members (n = 1,586, 83.0%) received any type of health service and 20.4% (n = 391) received an opioid-related health service in the 30 days prior to filling naloxone. Additionally, 12.7% (n = 242) of members had received medication for opioid use disorder (MOUD), and 42.6% (n = 815) filled a prescription opioid analgesic within the 60 days prior to filling naloxone. Nineteen members (1.0%) had an emergency department visit for overdose within 90 days after filling naloxone. CONCLUSION: Standing orders play an important role in providing access to naloxone, even among Medicaid members who had recent encounters with health care providers. We identified multiple opportunities to improve naloxone prescribing among providers caring for Medicaid-insured people who use opioids, including prescribers of opioid analgesics or MOUD.

Mixed Method Evaluation of Louisiana's Prerelease Medicaid Enrollment Program, 2017-2019.

BACKGROUND: Over 600,000 people leave US prisons annually. Many are eligible for Medicaid upon release but may need support to enroll. Carceral facilities in nearly half of states have implemented systems to facilitate Medicaid access for those leaving incarceration, but there is limited information on program implementation models or outcomes. OBJECTIVES: To evaluate implementation and initial outcomes of Louisiana's prison-based Prerelease Medicaid Enrollment Program. METHODS: In this mixed-methods study, we assessed enrollment in Louisiana Medicaid at time of release from prison in the 2 years (2017-2018) after Program implementation, as well as reasons for Medicaid closure (ie, loss of coverage) and health services use 6 months postrelease. In May-June 2019, we conducted interviews statewide with program implementers (n=16) and focus groups in New Orleans, Louisiana with formerly incarcerated Program participants (n=16). RESULTS: A total of 4476 people were included in the quantitative analysis. There was a 34.3 (95% confidence interval: 20.7-47.9) percentage point increase in Medicaid enrollment upon release. Nearly all (98.6%) attended at least 1 outpatient visit and almost half (46.7%) had 1 emergency department visit within 6 months of release. Not responding to information requests was the most common reason for Medicaid closure. Program implementers and formerly incarcerated participants identified Program strengths, barriers, and suggestions for improvement. CONCLUSIONS: The program was successful in rapidly increasing Medicaid enrollment at the time of prison release and facilitating the use of health care services.

Depression at the Intersection of Race/Ethnicity, Sexual Orientation, and Income.

The current study uses an intersectional framework to examine subgroup differences in the prevalence of depression among a community sample of predominantly low-income, racial/ethnic and sexual minority adults. Between May 2017-June 2018, participants (N=1753) were recruited from and screened for depression in community organizations that predominantly serve sexual minority clients based in Los Angeles, California and New Orleans, Louisiana. Twenty-six percent of people screened for study eligibility met criteria for depression (Patient Health Questionnaire-8≥10). As is true in higher-resourced populations, bisexual (Odds Ratio; OR: 1.50; 95% Confidence Interval; CI: 1.08, 2.09) and queer/questioning (OR: 1.86; 95% CI: 1.08, 3.19) individuals were more likely to be depressed than heterosexual and lesbian/ gay individuals. These differences remained even when accounting for income. No differences in depression were observed between lesbian/gay and heterosexual adults. In terms of racial differences, bisexual Black (OR: .47; 95% CI: 0.21, 1.04) and Hispanic (OR: .51; 95% CI: 0.23, 1.12) adults were marginally less likely to be depressed than bisexual White adults. No racial differences emerged across other sexual orientations. Differences across some sexual minority subgroups may be race-specific, suggesting that intersectional frameworks may be the best way to understand how multiple marginalization affects different subgroups.

Medicaid Utilization Before and After a Natural Disaster in the 2016 Baton Rouge-Area Flood.

Objectives. To understand changes in behavioral health services utilization and expenditures before and after natural disaster with an adult Medicaid population affected by the Baton Rouge, Louisiana-area flood (August 2016).Methods. We examined de-identified behavioral health claims data for Medicaid-insured adults in the affected region for 10 months before and after flooding (October 2015-June 2017). This constituted 273 233 provider claims for 22 196 individuals. Claims data included patient gender, behavioral health diagnoses, treatment dates, and costs. We made adjustments for Medicaid expansion by using monthly enrollment data.Results. Overall, most male patient behavioral health care visits were for substance use disorders (33.6%) and most female patient behavioral health care visits were for depression-related disorders (30%). Both diagnostic categories increased after the flood by 66% and 44%, respectively. Expansion accounted for a 4% increase in claims. Postflood claims reflected 8% to 10% higher costs.Conclusions. Greater amounts of behavioral health care services were sought in all 10 months of the postflood study period. We observed gender differences in use of services and diagnoses. Behavioral health care services following natural disasters must be extended longer than traditionally expected, with consideration for specific population needs.

Preparedness and Community Resilience in Disaster-Prone Areas: Cross-Sectoral Collaborations in South Louisiana, 2018.

Objectives. To determine how community-based organizations (CBOs) define priorities for bolstering community resilience, challenges in addressing these priorities, and strategies to address challenges.Methods. The Community Resilience Learning Collaborative and Research Network (C-LEARN) is a multiphase study examining opportunities to improve community resilience to the threats of disaster and climate change in South Louisiana. Phase I of C-LEARN involved using the National Health Security Strategy and Implementation Plan for directed content analysis of key informant interviews with CBO representatives from 47 agencies within South Louisiana between February and May 2018.Results. CBO interviewees highlighted the importance of forging relationships and building trust through diverse cross-sector collaborations and partnerships before disasters. Such collaborations and partnerships were shown to tailor disaster response to the needs of particular communities and populations as well as address key challenges such as gaps in information, services, and resources.Conclusions. Our results encourage a culture of community resilience and community preparedness through partnerships and community-engaged strategies. C-LEARN will utilize the results of our interviews in the design of phase II of our agency-level coalition-building intervention.

The Community and Patient Partnered Research Network (CPPRN): Application of Patient-Centered Outcomes Research to Promote Behavioral Health Equity.

Objective: We describe the rationale, development, and progress on the Community and Patient Partnered Research Network (CPPRN). The CPPRN builds on more than a decade of partnered work and is designed to promote health equity by developing partnered research on behavioral health and social risk factors in Los Angeles and New Orleans. Setting: A community-academic partnership across Los Angeles County and New Orleans. Methods: Review of rationale, history, structure, activities and progress in applying community partnered participatory research (CPPR) to CPPRN. Findings: Patient and community stakeholders participated in all phases of development, including local and national activities. Key developments include partnered planning efforts, progress on aggregating a large, de-identified dataset across county agencies, and development of an information technology-supported screening approach for behavioral and social determinants in health care, social, and community-based settings. Conclusion: The CPPRN represents a promising approach for research data networks, balancing the potential benefit of information technology and data analytic approaches while addressing potential risks and priorities of relevant stakeholders.

Medications For Opioid Use Disorder Increased Among Louisiana Medicaid Enrollees During Policy Reforms, 2018-21.

Increasing access to medications for opioid use disorder (MOUD) is a key strategy in addressing the opioid crisis. To increase MOUD access, state governments have pursued a combination of increased funding for MOUD and requirements that providers offer treatment. Louisiana has pursued multiple strategies, including a requirement that residential treatment programs offer MOUD as part of their licensure. Using Louisiana Medicaid claims data for enrollees with diagnosed OUD from the period 2018-21, we analyzed trends in MOUD between enrollees treated in residential and nonresidential settings and across demographic subgroups, and we compared trends by MOUD type. MOUD use more than tripled from 2018 to 2021 among Louisiana Medicaid enrollees diagnosed with OUD. Most of the increase in MOUD was attributable to buprenorphine use. Methadone uptake also contributed to greater MOUD use but was almost exclusively used by enrollees treated in nonresidential settings, whereas naltrexone was consistently more common in residential treatment. By 2021, differences persisted across demographic groups: MOUD use was highest among enrollees who were White, were older, had comorbidities, and lived in a metropolitan area. Policies that promote MOUD in substance use treatment programs, particularly residential programs, are critical tools for policy makers confronting a complex and unprecedented national overdose crisis.

Personal Experiences With Xylazine and Behavior Change: A Qualitative Content Analysis of Reddit Posts.

OBJECTIVES: Xylazine is a rapidly spreading adulterant in the United States' drug supply and is increasingly associated with overdoses and severe wounds, but there is a dearth of information about the clinical presentation or means of treatment for human xylazine exposure. The objective of this study was to explore personal attitudes about xylazine in the drug supply and experiences with xylazine-related use among people who reported using drugs and contributed content to social media site Reddit. METHODS: To conduct a retrospective qualitative content analysis, the study team extracted all posts and comments from Reddit, which mentioned the terms "xylazine" or "tranq." Content was extracted from 10 Reddit forums, or subreddits, specific to drug use, and included content created on or before the extraction date of January 2023. In total, 3284 posts were identified and 1803 were qualitatively coded using an inductive approach until meaning saturation was reached. RESULTS: Three themes emerged across comments and posts: (1) personal experiences with xylazine, including a negative impact on overdose, withdrawal, and wounds; (2) behavior changes in response to xylazine in the drug supply, including devising and sharing new harm reduction and detection tips, and reducing or abstaining from drug use altogether; (3) a perceived lack of treatment options for xylazine withdrawal and information sharing to help others self-treat withdrawal symptoms, most often with clonidine. CONCLUSIONS: This study of people who reported using drugs with xylazine provides new insights into how xylazine is perceived, possible treatment modalities, and potential clinical research approaches.

A content analysis of legal policy responses to xylazine in the illicit drug supply in the United States.

BACKGROUND: Xylazine is a veterinary sedative that is quickly spreading in the U.S. illicit drug supply and is increasingly associated with fatal overdoses and severe wounds. In response, xylazine has been deemed an emerging public health threat and several policy initiatives have been introduced to combat its spread and negative broad health impact. We aimed to synthesize trends in all-time U.S. policy responses to xylazine in the drug supply. METHODS: In April 2024, we systematically identified and categorized proposed and enacted policy initiatives that related to human xylazine consumption by searching LexisNexis and Thomas Reuters Westlaw legal databases. RESULTS: Of 58 unique policy initiatives, most were introduced in 2023 (n = 37/58, 64 %) and concentrated in Northeastern states. Penalties for xylazine possession, often tied to state drug scheduling changes, were the most common provision (n = 34/58; 59 %) and Schedule III was the most frequently proposed scheduling level (n = 17/30; 57 %). Other provisions included proposals to enhance: test strip access (n = 11/58; 19 %), public awareness and education (n = 3/58; 5 %), xylazine-specific research (n = 4/58; 7 %), and surveillance (n = 8/58; 14 %). CONCLUSION: U.S. state and federal policy responses to xylazine grew rapidly in 2023, were most concentrated in states affected most by xylazine, and scheduling was the most commonly proposed policy approach. Research measuring policy effects should be prioritized as policies are implemented.

Piloting racial bias training for hospital emergency department providers treating patients with opioid use disorder.

Racial disparities in opioid overdose have increased in recent years. Several studies have linked these disparities to health care providers' inequitable delivery of opioid use disorder (OUD) services. In response, health care policymakers and systems have designed new programs to improve equitable OUD care delivery. Racial bias training has been 1 commonly utilized program. Racial bias training educates providers about the existence of racial disparities in the treatment of people who use drugs and the role of implicit bias. Our study evaluates a pilot racial bias training delivered to 25 hospital emergency providers treating patients with OUDs in 2 hospitals in Detroit, Michigan. We conducted a 3-part survey, including a baseline assessment, post-training assessment, and a 2-month follow-up to evaluate the acceptability and feasibility of scaling the racial bias training to larger audiences. We also investigate preliminary data on changes in self-awareness of implicit bias, knowledge of training content, and equity in care delivery to patients with OUD. Using qualitative survey response data, we found that training participants were satisfied with the content and quality of the training and especially valued the small-group discussions, motivational interviewing, and historical context.

Association of buprenorphine retention and subsequent adverse outcomes following non-fatal overdose: An analysis using statewide linked Maryland databases.

INTRODUCTION: Patients receiving buprenorphine after a non-fatal overdose have lower risk of future nonfatal or fatal overdose, but less is known about the relationship between buprenorphine retention and the risk of adverse outcomes in the post-overdose year. OBJECTIVE: To examine the relationship between the total number of months with an active buprenorphine prescription (retention) and the odds of an adverse outcome within the 12 months following an index non-fatal overdose. MATERIALS AND METHODS: We studied a cohort of people with an index non-fatal opioid overdose in Maryland between July 2016 and December 2020 and at least one filled buprenorphine prescription in the 12-month post-overdose observation period. We used individually linked Maryland prescription drug and hospital admissions data. Multivariable logistic regression models were used to examine buprenorphine retention and associated odds of experiencing a second non-fatal overdose, all-cause emergency department visits, and all-cause hospitalizations. RESULTS: Of 5439 people, 25% (n=1360) experienced a second non-fatal overdose, 78% had an (n=4225) emergency department visit, and 37% (n=2032) were hospitalized. With each additional month of buprenorphine, the odds of experiencing another non-fatal overdose decreased by 4.7%, all-cause emergency department visits by 5.3%, and all-cause hospitalization decreased by 3.9% (p<.0001, respectively). Buprenorphine retention for at least nine months was a critical threshold for reducing overdose risk versus shorter buprenorphine retention. CONCLUSIONS: Buprenorphine retention following an index non-fatal overdose event significantly decreases the risk of future overdose, emergency department use, and hospitalization even among people already on buprenorphine.

Harm Reduction and Treatment Among People at High Risk of Overdose.

Importance: Rates of overdose deaths involving synthetic opioids remain high, increasingly involve stimulants combined with opioids, and are increasing rapidly in racially and ethnically minoritized communities, yet little is known about access to harm reduction and treatment services in these groups. Objective: To characterize access and barriers to harm reduction and treatment in a racially and ethnically diverse population of people who use drugs. Design, Setting, and Participants: A cross-sectional telephone survey of people recruited from 39 treatment, harm reduction, and social service organizations in Milwaukee County, Wisconsin; Flint and Detroit, Michigan; and statewide in New Jersey was conducted from January 30 to July 28, 2023. Adults who used cocaine, methamphetamine, or opioids in the past 30 days called a study hotline and completed an interview in English or Spanish. Exposures: Overdose experience, drug types used (opioids only, stimulants only, and polysubstance), and social risk factors (eg, financial instability and criminal legal involvement). Main Outcomes and Measures: Recent use of any harm reduction services, fentanyl test strips, naloxone possession, treatment, and self-reported barriers to services. Results: Of the total sample of 1240 adults, 486 (39.2%) were Black non-Hispanic, 183 (14.8%) were Hispanic, and 464 (37.4%) were White non-Hispanic. In the past 30 days, 826 individuals (66.6%) were polysubstance users, 135 (10.9%) used only opioids, and 279 (22.5%) used only stimulants. A total of 349 respondents (28.1%) experienced a prior-year overdose. Compared with those without a prior-year overdose, people with overdose were more likely to possess naloxone (80.7% vs 68.2%; P < .001), possess fentanyl test strips (36.8% vs 23.5%; P < .001), and use harm reduction services (63.4% vs 53.0%; P = .003), while differences in treatment use were nonsignificant (52.0% vs 46.6%; P = .24). Among stimulant-only users, 51.4% possessed naloxone compared with 77.3% of opioid-only users (P < .001) and 77.6% of polysubstance users (P < .001), with similar disparities in fentanyl test strip possession. Conclusions and Relevance: In this cross-sectional study of people who used drugs in the past 30 days, findings highlighted low use of harm reduction and treatment services among people who use stimulants. Additional communication regarding their importance may help increase the use of the services amidst a rapidly changing drug supply.

Perceptions of a naloxone leave behind program among emergency medical services personnel in Michigan, USA.

Introduction: In 2020, Michigan implemented its first Naloxone Leave-Behind Program for Emergency Medical Service (EMS) field providers. Under the program, EMS field providers leave naloxone kits to individuals aged 15 or older they encounter in the field who have overdosed, who indicate they have a substance use disorder, or exhibit signs of opioid use and/or to bystanders, friends, or family that are present at the encounter. Methods: Survey of EMS field providers and administrators to assess perspectives on the Michigan NLB program. Comparisons of perspectives between field providers and administrators working in EMS agencies operating in medical control authorities (MCAs) participating in the NLB program (i.e., participating agencies) with field providers and administrators working for EMS agencies serving non-participating MCAs. Results: Most EMS field providers and administrators supported the Michigan NLB program. However, some were concerned about the unintended consequences of leaving behind naloxone, including the potential for recipients to use more drugs or be less likely to seek treatment. Perspectives of NLB program effectiveness were similar between EMS administrators and field providers. Participating administrators' top-cited barrier to implementation was convincing field providers to leave behind naloxone, while non-participating administrators were concerned with stocking naloxone kits. Conclusions: Additional engagement and training to address concerns by EMS field providers and administrators about the benefits of the NLB program are needed to expand program participation intensity. Streamlining naloxone procurement and increasing messaging about free access to naloxone for participating in the program may help increase adoption.

Health services use among formerly incarcerated Louisiana Medicaid members within one year of release.

OBJECTIVES: To determine the association between enrollment in Medicaid prior to release compared with post-release, and the use of health services and time to the first service use after release among Louisiana Medicaid members within one year of release from Louisiana state corrections custody. METHODS: We conducted a retrospective cohort study linking Louisiana Medicaid and Louisiana state corrections release data. We included individuals ages 19 to 64 years released from state custody between January 1, 2017 and June 30, 2019 and enrolled in Medicaid within 180 days of release. Outcome measures included receipt of general health services (primary care visits, emergency department visits, and hospitalizations), cancer screenings, specialty behavioral health services, and prescription medications. To determine the association between pre-release Medicaid enrollment and time to receipt of health services, multivariable regression models were used which accounted for significant differences in characteristics between the groups. RESULTS: Overall, 13283 individuals met eligibility criteria and 78.8% (n = 10473) of the population was enrolled in Medicaid pre-release. Compared with those enrolled in Medicaid prior to release, those enrolled post-release were more likely to have an emergency department visit (59.6% versus 57.5%, p = 0.04) and hospitalization (17.9% versus 15.9%, p = 0.01) and less likely to receive outpatient mental health services (12.3% versus 15.2%, p<0.001) and prescription drugs. Compared with those enrolled in Medicaid prior to release, those enrolled post-release had a significantly longer time to receiving many services including a primary care visit (adjusted mean difference: 42.2 days [95% CI: 37.9 to 46.5; p<0.001]), outpatient mental health services (42.8 days [95% CI: 31.3 to 54.4; p<0.001]), outpatient substance use disorder service (20.6 days [95% CI: 2.0 to 39.2; p = 0.03]), and medication for opioid use disorder (40.4 days [95% CI: 23.7 to 57.1; p<0.001]) as well as inhaled bronchodilators and corticosteroids (63.8 days [95% CI: 49.3 to 78.3, p<0.001]), antipsychotics (62.9 days [95% CI: 50.8 to 75.1; p<0.001]), antihypertensives (60.5 days [95% CI: 50.7 to 70.3; p<0.001]), and antidepressants (52.3 days [95% CI: 44.1 to 60.5; p<0.001]). CONCLUSION: Compared with Medicaid enrollment post-release, pre-release Medicaid enrollment was associated with higher proportions of, and faster access to, a wide variety of health services. Regardless of enrollment status, we found prolonged times between release and receipt of time-sensitive behavioral health services and prescription medications.
