ObjectivesMany emergency department (ED) patients with opioid use disorder are candidates for home buprenorphine/naloxone initiation with to-go packs. We studied patient opinions and acceptance of buprenorphine/naloxone to-go packs, and factors associated with their acceptance.MethodsWe identified patients at two urban EDs in British Columbia who met opioid use disorder criteria, were not presently on opioid agonist therapy and not in active withdrawal. We offered patients buprenorphine/naloxone to-go as standard of care and then administered a survey to record buprenorphine/naloxone to-go acceptance, the primary outcome. Survey domains included current substance use, prior experience with opioid agonist therapy, and buprenorphine/naloxone related opinions. Patient factors were examined for association with buprenorphine/naloxone to-go acceptance.ResultsOf the 89 patients enrolled, median age was 33 years, 27% were female, 67.4% had previously taken buprenorphine/naloxone, and 19.1% had never taken opioid agonist therapy. Overall, 78.7% believed that EDs should dispense buprenorphine/naloxone to-go packs. Thirty-eight (42.7%) patients accepted buprenorphine/naloxone to-go. Buprenorphine/naloxone to-go acceptance was associated with lack of prior opioid agonist therapy, less than 10 years of opioid use and no injection drug use. Reasons to accept included initiating treatment while in withdrawal; reasons to reject included prior unsatisfactory buprenorphine/naloxone experience and interest in other treatments.ConclusionAlthough less than half of our study population accepted buprenorphine/naloxone to-go when offered, most thought this intervention was beneficial. In isolation, ED buprenorphine/naloxone to-go will not meet the needs of all patients with opioid use disorder. Clinicians and policy makers should consider buprenorphine/naloxone to-go as a low-barrier option for opioid use disorder treatment from the ED when integrated with robust addiction care services.© 2023.
