This study will address this emerging need to increase access to buprenorphine and extended-release naltrexone by testing a bundle of practices, called the Prescriber Recruitment Bundle (PRB), which aims to recruit prescribers licensed to prescribe buprenorphine to work with addiction treatment organizations. The PRB consists of the following elements, a) candidate identification strategies, b) prescriber education forums, c) prescriber-friendly workflow and risk-reduction strategies, d) academic detailing to recruit OUD prescribers, e) telemedicine to provide access to OUD pharmacotherapies, and f) organizational leadership and culture to support building OUD pharmacotherapy capacity.
