Evaluation of a Peer Recovery Support Program Adapted to Target Retention in Clinic-based Medication for Opioid Use Disorder Treatment

The goal of this clinical trial is to learn if receiving peer recovery support (support services provided by trained "peers" with lived experience of addiction and recovery) improves retention in medication treatment among people with opioid use disorder. The main question it aims to answer is: does peer recovery support improve retention in medication treatment for opioid use disorder? Researchers will compare two groups: (1) standard care combined with a peer recovery support program, and (2) standard care alone, to see if peer recovery support works to improve retention in medication treatment for opioid use disorder. Participants will: visit clinics as they normally would to receive standard care (medication treatment for opioid use disorder); complete two questionnaires - one when they start treatment and one 6 months later; and agree to let researchers use information from their medical record. Participants in group 1 will also be invited to meet with a peer recovery support specialist for up to 6 months.
