Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who meet DSM-5 criteria for opioid use disorder and are starting a new medication for opioid use disorder treatment.
✕Probably not a fit
Patients who have recently been prescribed or administered more than 72 hours of medication for opioid use disorder or those with severe comorbid conditions may not benefit from this study.

What this trial studies
This clinical trial aims to compare the effectiveness of office-based methadone with pharmacy administration to office-based buprenorphine in retaining patients undergoing treatment for opioid use disorder. It is a randomized, pragmatic hybrid effectiveness and implementation trial conducted across approximately six sites, involving around 600 patients. The study will also explore barriers and facilitators to implementing office-based methadone treatment from the perspectives of patients, providers, and health systems.
Why it matters
Potential benefit: If successful, this study could improve retention rates in treatment for patients with opioid use disorder.
How similar studies have gone: Previous studies have shown varying success with similar approaches, but this specific comparison of office-based methadone and buprenorphine is relatively novel.
