What this research studies

If I join, outreach teams will bring low-barrier mobile services directly into Baltimore neighborhoods, offering naloxone, safer use supplies, individual counseling, and help linking to HIV, HCV, and other care. The project will enroll about 400 women who use drugs and follow them over time to track nonfatal overdoses and engagement with clinical services. The researchers use a hybrid effectiveness-implementation approach to measure both health outcomes and how well the mobile program is delivered in new neighborhoods. The team will focus on services tailored to women's needs and document barriers and facilitators to reaching people where they are.

Who could benefit from this research

Good fit: Ideal candidates are adult women who use drugs and live in Baltimore City or County neighborhoods served by the Mobile SPARC outreach program.

Not a fit: People who do not use drugs, live outside the targeted Baltimore City/County area, or already have stable, comprehensive harm-reduction and treatment services are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could reduce nonfatal overdoses among women who use drugs and increase their access to HIV, HCV, and other healthcare services.

How similar studies have performed: Other mobile harm-reduction and naloxone distribution programs have shown benefits in reducing overdoses, but a women-centered mobile model like this is relatively novel.
