Shared decision-making to prevent or treat HIV for people with recent justice involvement
Official title: STOP (Shared Decision Making to Treat Or Prevent) HIV in Criminal Legal Involved Populations
Run by Yale University · NCT07223398 · Data updated 2026-11-12
This project tests whether offering a shared decision-making 'patient choice' menu alongside standard patient navigation helps people with recent justice involvement start HIV prevention (PrEP) or treatment (ART) and begin substance use disorder care.

Is this trial a fit for you?
✓Likely a good fit
Adults living in the study regions with justice involvement within the past six months who report recent opioid or stimulant use, are willing to have HIV testing, and either are not currently on ART or are HIV-negative and meet CDC PrEP criteria are the intended participants.
✕Probably not a fit
People with severe medical or psychiatric conditions that make participation unsafe, those unable to give informed consent, those not living in the study catchment areas, or individuals already consistently taking ART or PrEP are unlikely to benefit from this intervention.

What this trial studies
This randomized R33 trial compares standard patient navigation (PN) to PN plus a Patient Choice (PC) shared decision-making menu across multiple U.S. sites. Eligible participants are people with justice involvement in the past six months who either have HIV and are not on ART or are HIV-negative and meet CDC PrEP criteria, and who report recent opioid or stimulant use. The primary outcomes are the proportions who initiate PrEP or ART and who start substance use/SUD treatment, and the study also measures implementation outcomes and costs. Study sites include Yale School of Medicine (CT), University of Kentucky (KY), and UT Southwestern Medical Center (Dallas, TX).
Why it matters
Potential benefit: If successful, this approach could increase uptake of PrEP/ART and substance use treatment among people re-entering the community after justice involvement, reducing HIV transmission risk and relapse.
How similar studies have gone: Prior work shows patient navigation can improve linkage to HIV care and treatment starts, but the shared decision-making 'patient choice' model in justice-involved populations has been less tested and is comparatively novel.
