OBJECTIVES: Determine if long-acting injectable buprenorphine (LAIB) can be successfully and safely administered in the hospital with minimal sublingual buprenorphine lead-in and potentially improve follow-up engagement in care.
METHODS: We performed a retrospective case series of 46 patients who received LAIB while hospitalized at a safety-net community hospital. We abstracted demographic information, details about substance use disorder treatment history, in-hospital buprenorphine initiation methods and follow-up data from inpatient and outpatient electronic medical records.
RESULTS: In total, 46 hospitalized patients received LAIB during the study period. The majority of our patients were older Black adults with Medicaid who self-reported intranasal heroin use. A low-dose buprenorphine initiation protocol was used most commonly, either in sublingual or intravenous form, with only two cases of precipitated withdrawal occurring during the buprenorphine initiation process and no cases of precipitated withdrawal after the administration of LAIB. 87% (40) of the patients received LAIB after receiving either sublingual or IV buprenorphine for fewer than the recommended seven days. Of the 46 hospitalized patients who received LAIB, 23 (50%) attended a follow-up addiction medicine appointment within 30 days of discharge.
CONCLUSIONS: Hospital administration of LAIB could play an important role in retention in care after hospital discharge.
