A Washington University smartphone app tied to a new study appears to sharply curb short-term illicit drug use among St. Louisans without stable housing, offering a low-cost lifeline for people who are often cut off from traditional care. Researchers found that people who logged into the uMAT-R app were about 50% less likely to report non-opioid illicit drug use within 30 days, and that messaging the app's e-coaches was linked to similar reductions in opioid use. The results are early but suggest local providers have another tool to reach people who face steep barriers to recovery.
Study finds lower 30-day drug use
The analysis relied on data from nearly 1,000 people enrolled in uMAT-R, with a one-month follow-up sample of 378 participants to track short-term outcomes. Using adjusted models, the research team reported an adjusted odds ratio of about 0.49 for other non-opioid illicit drug use among people who logged into the app, and roughly a 0.39 adjusted odds ratio for reduced opioid use among participants who messaged an e-coach. Higher engagement also lined up with fewer cravings and lower perceived burdensomeness, factors tied to longer-term recovery, as detailed in Drug and Alcohol Dependence.
What's inside uMAT-R
uMAT-R, pronounced "you matter," packages short educational modules, a community resource directory, a sobriety tracker and an in-app chat that links users with trained e-coaches during the workweek. Washington University says the tool, developed and launched in 2018 by a team led by Patricia Cavazos-Rehg, was designed to meet people "where they are" and to tackle barriers beyond medication, including housing, food and employment. The university notes that uMAT-R is funded in part by the Missouri Department of Health & Senior Services. "There is a lot of overlap with people who are experiencing housing insecurity and have substance use disorders," said lead author Vidya Eswaran, according to WashU Medicine.
How people can get on the app
uMAT-R is not something you can just grab from an app store. Enrollment typically happens through treatment centers, emergency departments and recovery partners instead of direct public sign-ups. Project materials and slides note that the team has implemented uMAT-R "across Missouri and southern Illinois," and they encourage providers and clients to reach out for step-by-step enrollment guidance, according to RecoveryAnswers.
Why it matters here
The findings hit close to home for St. Louis, where many people who use drugs also struggle with unstable housing and can easily fall through the cracks of clinic-based care. Local reporting on the Washington University study underscores how digital tools like uMAT-R can sidestep some of the biggest barriers to treatment, including transportation, rigid schedules and stigma that can keep people away from brick-and-mortar programs, as reported by St. Louis Public Radio.
How to learn more or connect
People in the region who are interested in the program can email [email protected] or call 314-944-2464 to ask about enrollment, e-coaching and provider partnerships, according to the project's outreach materials. Researchers describe uMAT-R as a promising, low-barrier supplement to existing care and say they plan to test adaptations for other high-risk groups, including people returning to the community after incarceration, according to RecoveryAnswers.
