NIH-funded research R01 grant

Mobile app plus peer support to help people with HIV and substance use stay healthy

Official title: Clinic-level implementation of mHealth to improve HIV viral suppression for patients with substance use disorders

Funded at University of Wisconsin-Madison · NIH-11285266 · Data updated 2026-11-12

This project uses a mobile health app together with trained peer mentors to help people living with HIV who also struggle with substance use stay on treatment and keep their viral load low.

Who could benefit from this research

Could help

Adults living with HIV who have current or recent substance use disorders and who receive care at one of the participating clinics are the intended candidates.

Less likely to help

People without substance use concerns, those not receiving care at participating clinics, or those without access to a smartphone are unlikely to benefit directly from this program.

What this research studies

You would be offered a mobile app (CHESS) that connects with your clinic and trained peer mentors who are also patients. The app collects real-time information about things like housing, food, alcohol or drug use, and medication taking to spot problems before they lead to missed care. Peer mentors use this information to build social support and connect you with the HIV Medical Home care team. The program is being rolled out across participating clinics in Colorado, Missouri, Texas, and Wisconsin and will track viral suppression and missed appointments.

Why it matters

Potential benefit: If successful, the program could help more people with HIV who use substances achieve and maintain viral suppression and miss fewer clinic visits.

How similar studies have gone: Previous mHealth and peer-support efforts have improved medication adherence and engagement in some studies, but implementing both at the clinic level across multiple states is relatively novel.
