Opioid use disorder (OUD) is a public health emergency, with a shortage of providers trained to prescribe buprenorphine for OUD treatment. We conducted a systematic review to examine advanced practice RN (APRN) and medical school programs that included OUD content or Drug Addiction Treatment Act waiver training and evaluate the outcomes of those curricular modifications. APRN and medical school programs that provided OUD content or waiver training saw improvements in students' knowledge and self-efficacy for managing buprenorphine treatment and reduced stigma toward individuals with OUD. Students' perceptions of training were largely positive, and the programs' results indicated improved practice outcomes related to the use of buprenorphine. Further inclusion of OUD content and training in APRN curricula will increase the number of capable buprenorphine prescribers, which will increase access to buprenorphine for individuals with OUD.
