(RE-)AIMing for Rapid Uptake

Abstract

Objective: Medication for opioid use disorder (MOUD) is an effective, evidence-based treatment, but significant gaps in implementation remain. We evaluate one novel approach to address this gap: a Hub and Spoke model to increase buprenorphine access and management. Methods: This outcome evaluation was guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework using secondary data analysis of clinical and administrative data to characterize program outcomes for program Reach, Effectiveness, Adoption, and Maintenance. Implementation was assessed through a chart review of provider progress notes and through key informant interviews with program staff to understand why this site was able to introduce a novel approach to MOUD. Results: Nearly half of patients with opioid use disorder (45.48%, n=156) were reached by the program over 2 years. Of those, 91.67% had 1 or more program visits after an initial intake appointment, and 78.85% had a buprenorphine prescription. Patients in the program were 2.44 times more likely to have a buprenorphine prescription than those in comparator site that did not have a Hub and Spoke program (95% CI: 1.77–3.37; P<0.001). There was significantly greater program reach in year 1 than year 2, suggesting rapid initial uptake followed by modest program growth. Key informant interviews illustrated several themes regrading program implementation, including the importance of process champions, the beneficial impact of MOUD for patients, and addressing facility performance metrics. A supportive organizational culture and a receptive climate were also key factors for implementation. Conclusions: This program led to rapid improvement in MOUD uptake across the facility. Future efforts should focus on improving program maintenance, including supporting the exchange of patients from the hub to appropriate spokes.
