PEth-boosted brief intervention for alcohol use in people with HIV
Official title: The Phosphatidylethanol (PEth) Results Communication (PERC) Study
Run by University of California, San Francisco · NCT07444359 · Data updated 2026-11-12
In this study, people with HIV who drink at risky levels are randomized to receive standard MOH counseling with or without a PEth blood test result to see if linking test results to counseling helps reduce drinking.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 and older with HIV in the Mbarara catchment area who have unhealthy alcohol use (AUDIT-C) or positive PEth, fluent in Runyankole or English, and able to consent.
✕Probably not a fit
Individuals without unhealthy alcohol use, those not fluent in the local languages, or those unable to provide informed consent may not benefit.

What this trial studies
This randomized feasibility study tests whether adding PEth biomarker feedback to a brief alcohol intervention is acceptable and feasible for people with HIV in Uganda. Eighty participants are evenly randomized to receive either the PEth-boosted brief intervention or the standard MOH brief counseling alone, with follow-up at 3 months. Primary outcomes focus on acceptability, appropriateness, and feasibility, using validated surveys. Secondary outcomes include readiness to reduce drinking, self-reported alcohol use, PEth levels, alcohol-related problems, and stigma. Data are collected via interviewer-administered surveys in English or Runyankole using REDCap.
Why it matters
Potential benefit: If successful, the approach could make brief alcohol counseling more effective and better aligned with patients’ biomarker information, potentially reducing unhealthy drinking among people living with HIV.
How similar studies have gone: Previous biomarker-augmented behavioral approaches have shown promise, but this exact PEth-boosted BI with HIV in Uganda is novel and pilot data are being collected.
