High-Dose Medications for Opioid Use Disorder and Retention in Care

Official title: High-Dose Medications for Opioid Use Disorder: Effects on Treatment Retention, Drug Use Patterns, and Overdose Risks Amidst the Fentanyl Crisis

Funded at Massachusetts General Hospital · NIH-11422040 · Data updated 2026-11-12

This project tests whether adjusted, higher-dose MOUD regimens can help people stay in treatment and reduce overdose risks during the fentanyl crisis.

Who could benefit from this research

Could help

Individuals with opioid use disorder who are on or considering medication-assisted treatment, particularly those with high fentanyl exposure or housing instability.

Less likely to help

Patients not receiving MOUD or those unlikely to benefit from dosing adjustments may see little to no improvement.

What this research studies

If funded, researchers will compare MOUD dosing strategies informed by international data to see which approaches keep people engaged in treatment and reduce risky drug use and overdoses. They will use VIDUS cohort data from Canada and rich U.S. information to examine dosing, titration, and maintenance needs for people who use fentanyl. The study combines longitudinal behavioral data, urine drug screens, and administrative records to understand how dosing affects outcomes in real-world settings. The goal is to identify practical dosing approaches that can be tested further in real-world and clinical contexts.

Why it matters

Potential benefit: If successful, patients could experience better treatment retention and fewer overdose events through optimized MOUD dosing.

How similar studies have gone: Prior observational data suggest dosing strategies can influence retention, but formal evaluation of higher-dose regimens in the fentanyl era is still emerging.
