What this research studies

If you have HIV and drink alcohol, this project would add a blood test called PEth to the usual brief counseling so you can see an objective measure of recent drinking. Counselors would share the PEth results with you, use them to set personalized goals, and monitor progress over time. The approach pairs a short alcohol-focused intervention with objective testing to boost self-awareness and motivation for change. The work is being carried out in HIV clinics in Uganda where unhealthy drinking and HIV are common.

Who could benefit from this research

Good fit: Adults living with HIV who receive care at participating clinics in Uganda and who report or are suspected to have unhealthy alcohol use would be the ideal candidates.

Not a fit: People who do not drink, who are not in HIV care at participating sites, or who decline blood testing or counseling are unlikely to benefit from this intervention.

Why it matters

Potential benefit: Showing an objective alcohol biomarker to patients could increase motivation to cut down drinking, improve adherence to antiretroviral therapy, and reduce HIV-related complications.

How similar studies have performed: Brief alcohol interventions in people with HIV have produced modest reductions in drinking, but using PEth biomarker feedback is a newer tactic with limited prior data.
