Contingency Management to Improve Medication for Opioid Use Disorder Continuation After the Emergency Department

Project Summary The goal of this pilot clinical trial is to assess contingency management (CM) for increasing attendance at outpatient clinics after Medication for Opioid Use Disorder (MOUD) prescription and clinic referral occurred in the hospital Emergency Department (ED). * The researchers will compare usual care (UC)+CM to UC alone to see if 1) CM works to promote MOUD clinic attendance after discharge from the ED and 2) demonstrate feasibility of providing CM in the ED and outpatient MOUD clinic settings. * Researchers will randomize 30 adults who started MOUD in the ED into two conditions. These conditions consist of (A) UC alone: A referral to an outpatient buprenorphine or methadone provider with reminders from STAR program staff or (B) UC+CM: UC plus financial incentives dependent on MOUD clinic attendance to receive an MOUD prescription. The primary outcome of interest is the number of participants who receive their first MOUD prescription from the outpatient clinic after discharge from the ED in UC+CM compared to the UC-only condition. A secondary outcome will be the proportion of participants who kept attending outpatient MOUD treatment by the end of the 30-day study period between UC+CM and UC conditions. An exploratory outcome will be biochemically-verified illicit opioid abstinence measured at day 30.
