Patients with opioid use disorder (OUD) frequently utilize hospitals due to soft tissue infections and other conditions that require inpatient level of care. Prior studies have indicated that OUD patients are often amenable to te initiating buprenorphine treatment and can be successfully linked to outpatient treatment. However, hospitalized OUD patients initiated on buprenorphine have much lower treatment retention rates at 6-months compared to OUD patients initiating treatment in the outpatient setting. As such, there is a great need to identify strategies to improve treatment retention in this patient population. There is a growing body of evidence for the benefits of recovery coaches, who provide peer-delivered support services in the community. Tracing their origin to mutual support groups to supplement traditional clinical services, recovery coaches are individuals with lived experience of recovery. Studies of recovery coaches have demonstrated greater treatment retention, reduced substance use, and reduced inpatient utilization. However, no prior studies have examined the impact of recovery coaches in improving buprenorphine treatment retention. As such, the aim of this 24-week study is to evaluate the impact of recovery coach intervention on rates of treatment retention, illicit opioid use, and readmission among hospitalized patients newly initiated on buprenorphine compared to the control intervention. Patients who are successfully initiated on buprenorphine will be eligible to enroll. . Assessments will be conducted at baseline, 4 weeks, 12 weeks, and 24 weeks.
