Integrating peer support services into primary care-based OUD treatment: Lessons from the Penn integrated model

Opioid use disorder (OUD) is a major public health emergency in the United States. In 2020, 2.7 million individuals had an OUD. Medication for opioid use disorder is the evidence-based, standard of care for treating OUD in outpatient settings, especially buprenorphine because it is effective and has low toxicity. Buprenorphine is increasingly prescribed in primary care, a setting that provides greater anonymity and convenience than substance use disorder treatment centers. Yet two-thirds of people who begin buprenorphine treatment discontinue within the first six months. Treatment dropout elevates the risks of return to use, infections, higher levels of medical care and related costs, justice system involvement, and death. One promising form of retention support is peer service programs. Peers combine their lived experience of substance use and recovery with formal training to help patients engage and persist in OUD treatment. They provide a range of services, including health education, encouragement and empathy, coping skills, recovery modeling, and concrete assistance in overcoming the situational barriers to retention. However, guidance is needed to define the peer role in primary care, the specific tasks peers should perform, the competencies those tasks require, training and professional development needs, and peer performance standards. Guidance also is needed to integrate peers into the care team, allocate and coordinate responsibilities among care team members, manage peer operations and workflow, and facilitate effective team communication. Here we describe a peer support program in the University of Pennsylvania Health System (UPHS or Penn Medicine) network of primary care practices. This paper details the program's core components, values, and activities. We also report the organizational challenges, unresolved questions, and lessons for the field in administering a peer support program to meet the needs of patients served by a large, urban medical system with an extensive suburban and rural catchment area. www.clinicaltrials.gov registration: NCT04245423. •Peer support services could improve retention in outpatient OUD treatment, where attrition often exceeds 60%. Retention helps achieve the individual and societal goals of reducing: (1) a return to opioid use, (2) infections, (3) high-cost emergency department visits and inpatient stays, (4) justice system involvement, and (5) overdose deaths.•New primary care models for OUD treatment are beg
