The importance of contextually specific support relationships in implementing programs to link people to medication...

This study uses the Practical, Robust, Implementation, and Sustainability Model (PRISM) and Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) model to describe how features of jail contexts are associated with the number of people linked to medication for opioid use disorder (MOUD) and sustainment of jail linkage programs implemented in Wave 1 of the HEALing Communities Study in Kentucky (HCS-KY) from 2021 to 22. The HCS-KY is part of a parallel-group, cluster-randomized wait-list controlled trial examining the effects of supporting wide-scale implementation of evidence-based practices to reduce opioid overdose deaths. One strategy involved implementation of MOUD linkage programs within five Kentucky county jails. Minutes from program planning and maintenance meetings led by HCS-KY implementation facilitators with linkage staff/supervisors and jail liaisons/partners (average of five participants/meeting) were coded following PRISM-RE-AIM using template analysis to understand variations in participation across sites as well as barriers to and facilitators of MOUD linkage implementation.

Across the five jails, 277 participants met with linkage staff during and/or post-incarceration for 1,119 visits conducted in-person or via phone/video conference. Twenty-six participants linked to community-based MOUD treatment during the implementation period. Participation differed across sites based on jail and linkage staff utilization of implementation support strategies but did not affect program sustainment, which all jails pursued in some form. Qualitative analysis yielded four overarching themes characterizing jail linkage program implementation. First, program integration into jail infrastructure entailed navigation of jail facilities and technologies as well as legal factors surrounding linkage staff backgrounds and information-sharing. Second, adapting the intervention to site-specific needs required providing training and implementation support to jail and linkage staff tailored to each jail context. Third, facilitating inter-organizational and cross-system coordination was related to collaboration successes and challenges among the HCS-KY team, linkage staff, the courts, and other provider partners. Finally, staffing and legal factors influenced sustainment.

Only ~ 10% of participants linked to community-based MOUD despite intensive implementation support, yet jails highly valued the program and planned for sustainment. Given the complexities in postponing treatment initiation until reentry, we call for simultaneous efforts to integrate MOUD screening and treatment into jail booking processes.
