Initiation of buprenorphine for opioid use disorder in the hospital setting: Practice models, challenges, and legal considerations.

Purpose: To provide health-system pharmacists with published examples of strategies utilized to offer buprenorphine to inpatients with opioid use disorder (OUD) along with information on challenges and legal considerations.

Summary: Hospitals and emergency departments (EDs) are a constant source of healthcare for patients with OUD. As a result, hospital practitioners can screen, diagnose, begin treatment, and facilitate transfer of care to the outpatient setting. Offering sublingual buprenorphine in the hospital can bridge the gap before outpatient care is established. Multiple studies have shown that initiating treatment in the ED or during inpatient hospitalization results in 47% to 74% of patients utilizing medication-assisted treatment at day 30 of follow-up, statistically superior to the rates achieved with brief interventions or referral alone. Moreover, initiating buprenorphine treatment in the ED has been shown to decrease healthcare costs. Despite the benefits of offering buprenorphine in the inpatient setting, several challenges must be solved by hospital administration, such as achieving clinician readiness to prescribe buprenorphine, developing relationships with outpatient providers of buprenorphine, and creating an efficient workflow. Treatment of OUD with buprenorphine is heavily regulated on the federal level. Pharmacists can participate in the development of these programs and ensure compliance with applicable laws.

Conclusion: As health systems continue to care for patients with OUD, starting buprenorphine in the inpatient setting can improve the transition to outpatient treatment. Several institutions have developed programs with positive results. With an understanding of the typical barriers and relevant laws when initiating buprenorphine in the hospital setting, health-system pharmacists can assist in the development and operation of these initiatives.
