Extended-release Buprenorphine Administered at Discharge in Hospitalized Persons With Opioid Use Disorder: A Case Series.

INTRODUCTION: Monthly subcutaneous injectable buprenorphine (XR-Bup) is an option for treatment of opioid use disorder (OUD) that addresses some sublingual buprenorphine adherence barriers and is infrequently offered to hospitalized patients with OUD. METHODS: A retrospective case series was performed for patients receiving XR-Bup upon discharge from 1 academic medical center. Demographic information, diagnoses, follow-up, and documented factors informing the selection of XR-Bup were extracted from the electronic health record. RESULTS: In 1 year, 37 hospitalized patients with OUD received XR-Bup at discharge. The average age was 37.6 years, and patients were primarily Medicaid insured with an injection-related infection. The most common documented factors informing the selection of XR-Bup were as follows: previous sublingual buprenorphine adherence barriers, concurrent stimulant use disorder, and patient preference. Sixty-four percent of patients scheduled for follow-up attended appointments, and 55% received a second dose of XR-Bup. CONCLUSIONS: Subcutaneous injectable buprenorphine is an option for OUD treatment among hospitalized patients providing 30 or more days of buprenorphine coverage in the postdischarge period.
