Is this trial a fit for you?

Likely a good fit

Adults (18+) with opioid use disorder who plan to start methadone in a participating CSAPA within seven days and agree to three months of follow-up are ideal candidates.

Probably not a fit

People who received methadone by prescription in the prior three months, those with unstable psychiatric or cognitive disorders, pregnant or breastfeeding people, those unable to communicate in French, or those planning early transfer to another prescriber or pharmacy are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults starting methadone treatment at participating French CSAPA centers are assigned to either the DIADEME autonomous nursing delivery strategy or to a control strategy. Under the DIADEME approach, trained CSAPA nurses deliver methadone on site and may adapt doses according to a pre-approved team protocol and medical validation, while all participants receive regular semi-structured interviews. Participants are followed for three months to document medication delivery, adherence, safety, and care trajectories. The trial builds on recent French regulatory changes that expand nurse roles to test feasibility and acceptability of nurse-managed initiation and delivery.

Why it matters

Potential benefit: If successful, this approach could make methadone initiation easier to access and allow nurses to safely manage treatment, potentially improving continuity of care.

How similar studies have gone: Nurse-led or task-shifting models for opioid treatment are relatively novel in France with limited published evidence, though similar approaches in other settings have shown mixed but sometimes promising results.
