Abstract
Background
Long-acting injectable buprenorphine (LAI-BUP) is safe and effective, however is underutilized. Little is known regarding how buprenorphine prescribers view LAI-BUP, and which medication attributes they prioritize when selecting opioid use disorder (OUD) treatment.
Methods
Secondary analysis of a national, cross-sectional survey of U.S. physicians prescribing buprenorphine for OUD. Respondents reported OUD caseload, LAI-BUP use, and importance of medication attributes (eg, efficacy, safety, ease of prescribing, administrative requirements). Providers were categorized as no LAI-BUP use or, among LAI-BUP prescribers, Low vs High use by a median split. Group comparisons used chi-square (or Fisher’s exact) tests for categorical variables and Jonckheere–Terpstra tests for ordinal responses.
Results
Among 125 respondents, 39 (31.2%) reported no LAI-BUP use. The remaining 86 (68.8%) were split evenly into Low and High use groups (n’s = 43). LAI-BUP use did not differ meaningfully by specialty, region, or practice setting. Greater LAI-BUP use was reported by providers with larger OUD panels. Ratings of medication attributes were uniformly high.
Conclusions
LAI-BUP remains underused, with uptake highest among clinicians managing larger OUD caseloads. Measured attitudes toward medication attributes did not explain these differences. Future work should assess clinic workflow, staffing, reimbursement, and REMS burden, testing targeted implementation strategies using mixed-methods trials.
