What this trial studies

This project aims to enhance HIV testing and service uptake among people who use drugs (PWUD) by implementing a peer-driven intervention called 'Prevention Ambassadors' (PA). In collaboration with a community-based syringe service program, the PA intervention will involve the distribution of HIV self-testing kits and local service information within the social networks of PWUD. The intervention will be piloted in Riverside County, California, to evaluate its effects, acceptability, and feasibility among participants. The approach focuses on leveraging peer influence to encourage HIV testing and access to services.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 who use drugs and have a social network of other drug users.

Not a fit: Patients who do not use drugs or are not willing to engage with their social networks about HIV testing may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly increase HIV testing rates and service engagement among vulnerable populations.

How similar studies have performed: Previous studies have shown that peer-driven interventions can effectively increase health service engagement among marginalized populations, suggesting potential success for this approach.
