Injectable buprenorphine during transition out of prison: A pilot partially randomized preference trial protocol.

Background: Individuals involved in the criminal legal system represent one of the most disproportionately affected populations in the opioid overdose crisis. Despite evidence of medications for opioid use disorder (MOUD) reducing overdose mortality, illicit opioid use, and recidivism, most correctional facilities do not offer these treatments. Sublocade and Brixadi, two distinct, branded, formulations of extended-release buprenorphine (XR-B), offer a promising approach to improving MOUD treatment adherence and reducing post-release overdose deaths.
