Antecedents of fatal overdose in an adult cohort identified through administrative record linkage in Indiana, 2015-2022.

BACKGROUND: The United States continues to experience unprecedented rates of overdose mortality and need to identify effective policies or practices that can be implemented. This study aims to measure the prevalence, frequency, timing, and rate of touchpoints that occurred prior to a fatal overdose where communities might intervene. METHODS: In collaboration with Indiana state government, we conducted record-linkage of statewide administrative datasets to vital records (January 1, 2015, through August 26, 2022) to identify touchpoints (jail booking, prison release, prescription medication dispensation, emergency department visits, and emergency medical services). We examined touchpoints within 12-months prior to a fatal overdose among an adult cohort and explored variation over time and by demographic characteristics. RESULTS: Over the 92-month study period there were 13,882 overdose deaths (89.3% accidental poisonings, X40-X44) in our adult cohort that were record-linked to multiple administrative datasets and revealed nearly two-thirds (64.7%; n=8980) experienced an emergency department visit, the most prevalent touchpoint followed by prescription medication dispensation, emergency medical services responses, jail booking, and prison release. However, with approximately 1 out of every 100 returning citizens dying from drug overdose within 12-months of release, prison release had the highest touchpoint rate followed by emergency medical services responses, jail booking, emergency department visits, and prescription medication dispensation. CONCLUSION: Record-linking administrative data from routine practice to vital records from overdose mortality is a viable means of identifying where resources should be situated to reduce fatal overdose, with potential to evaluate the effectiveness of overdose prevention efforts.

Alliances to disseminate addiction prevention and treatment (ADAPT): A statewide learning health system to reduce substance use among justice-involved youth in rural communities.

BACKGROUND: Youth in the justice system (YJS) are more likely than youth who have never been arrested to have mental health and substance use problems. However, a low percentage of YJS receive SUD services during their justice system involvement. The SUD care cascade can identify potential missed opportunities for treatment for YJS. Steps along the continuum of the cascade include identification of treatment need, referral to services, and treatment engagement. To address gaps in care for YJS, we will (1) implement a learning health system (LHS) to develop, or improve upon, alliances between juvenile justice (JJ) agencies and community mental health centers (CMHC) and (2) present local cascade data during continuous quality improvement cycles within the LHS alliances. METHODS/DESIGN: ADAPT is a hybrid Type II effectiveness implementation trial. We will collaborate with JJ and CMHCs in eight Indiana counties. Application of the EPIS (exploration, preparation, implementation, and sustainment) framework will guide the implementation of the LHS alliances. The study team will review local cascade data quarterly with the alliances to identify gaps along the continuum. The study will collect self-report survey measures longitudinally at each site regarding readiness for change, implementation climate, organizational leadership, and program sustainability. The study will use the Stages of Implementation Completion (SIC) tool to assess the process of implementation across interventions. Additionally, the study team will conduct focus groups and qualitative interviews with JJ and CMHC personnel across the intervention period to assess for impact. DISCUSSION: Findings have the potential to increase SUD need identification, referral to services, and treatment for YJS.

Arrest and emergency medical services events among participants from one of the first mental health courts.

OBJECTIVE: This study looked at, in addition to subsequent arrest, emergency medical services (EMS) events as an outcome of participation in mental health court (MHC). METHODS: We linked information from participants of a MHC in Marion County, Indiana with jail booking and EMS services data. To understand programmatic impact, we looked at differences in jail bookings and EMS events within one year prior to and one year after MHC participation. We ran paired t-tests to understand whether correlations were significant. We also considered differences in outcomes between those who successfully completed MHC versus those who did not. RESULTS: MHC participation was significantly associated with a reduction in jail bookings and EMS events in the 12 months after program participation compared to the 12 months before. When comparing MHC participant groups, a significant reduction in jail bookings is found consistently whereas a significant reduction in EMS events was found in only some participant groups: the entire MHC group and the misdemeanor-level court (PAIR) participants when they successfully completed the program. CONCLUSIONS: EMS utilization should be an outcome of consideration in evaluating the success and cost savings of MHCs. Where MHCs do not result in significantly reduced EMS events, communities should consider what individual-level and community-level factors contribute to this and adjust accordingly.
