About this trial

The goal of this pragmatic randomized controlled trial is to compare treatment outcomes of two strategies for initiating buprenorphine treatment (low-dose initiation and direct-to-inject) in adults with opioid use disorder (OUD) who use fentanyl. This study aims to:

1. Compare effectiveness of each strategy on treatment retention in a real world, clinical setting, and 2. Assess differences between strategies in patient-reported outcomes, including withdrawal symptoms, cravings, drug use, treatment satisfaction, and overall acceptability.

Participants will:

1. Be randomized to initiate buprenorphine via a low-dose initiation or direct-to-inject protocol at an outpatient buprenorphine clinic, 2. Keep a diary of craving and withdrawal symptoms for the first 7 days after initiation, and 3. Visit the outpatient clinic 7, 30, and 90 days after initiation for urinary drug screen and follow-up surveys.
