Programs to increase linkage to medications for opioid use disorder (MOUD) through peer recovery coaches may hold promise in increasing MOUD initiation. However, the impact of linkage programs may vary based on contextual factors, such as the implementation setting. This study examines whether implementation setting is associated with MOUD initiation following participation in peer-based linkage programs. The University of Kentucky and Voices of Hope Lexington, a recovery community organization, trained recovery coaches to implement a MOUD linkage program. Coaches were deployed in 9 criminal-legal organizations (ie, jails, specialty court, and pretrial services) and 20 community organizations in 4 rural and 4 urban counties. Coaches worked with participants (n = 754) to set person-centered goals, provided MOUD education, addressed MOUD initiation barriers, and assisted with scheduling appointments. A typology of implementation setting categorized participants by where they enrolled in the linkage program: (1) urban community organizations (reference group), (2) urban criminal-legal organizations, (3) rural community organizations, or (4) rural criminal-legal organizations. The odds of MOUD initiation were estimated using multivariate logistic regression. Of 754 participants, 23.1% (n = 174) reported initiating MOUD. Relative to urban community organizations, individuals enrolled in rural community organizations were more likely to initiate MOUD (odds ratio = 1.85, P = 0.04), whereas individuals enrolled in rural criminal-legal organizations were less likely to initiate MOUD (odds ratio = 0.34, P = 0.005). Implementation setting may impact the likelihood of MOUD initiation through peer-based linkage programs. Future research should examine how implementation strategies might overcome setting-specific barriers to MOUD initiation, particularly in rural criminal-legal settings.
