Zambia Common Elements Treatment Approach Pilot Study

Alcohol misuse is a major unaddressed barrier to ending the HIV/AIDS epidemic. Hazardous drinking increases HIV transmission, delays antiretroviral therapy (ART) uptake, reduces adherence and retention, and increases mortality. Comorbid mental health or substance misuse, similar to alcohol use alone, can also significantly undermine HIV treatment. The vast majority of people living with HIV globally live in low- and middle-income countries (LMIC). Similar to most HIV care settings in LMIC, in Zambia, the location of the current study, there are no readily available evidence-based treatments for alcohol misuse or mental health problems.

This study will enroll persons living with HIV (PLWH) who have alcohol misuse in Zambia. Participants will be recruited and screened during regular HIV care visits. Participants will be recruited by their regular care providers (i.e., peer educators, counselors, nurses, physicians) and referred to study staff if they are interested. The investigators anticipate enrolling up to 320 participants, all of whom have hazardous alcohol use. N=160 participants will be high-risk drinkers due to having either a moderate-to-severe alcohol use disorder or mental health comorbidities, or both. These participants will be randomized into the RCT. Participants who have hazardous alcohol use (but not a moderate-to-severe AUD) without mental health comorbidities (a lower risk group of participants) will not be enrolled into the RCT but will be tracked as part of a parallel cohort study. The minimum age of research subjects will be 18. Eligibility will be assessed via audio computer assisted self-interviewing (ACASI).

Participants in the 'cohort study' (i.e., lower risk participants) will receive a brief alcohol intervention. Participants in the RCT (i.e., higher risk participants) will be randomly assigned on a 1:1 basis (stratified by gender) to receive the brief intervention alone or the brief intervention plus CETA.

All participants will be evaluated for outcomes at baseline and at a six month follow-up visit. For RCT participants, the investigators will compare the effectiveness of the brief intervention alone to the brief intervention plus CETA in reducing alcohol misuse and mental health problems. For cohort participants, the investigators will collect preliminary data on whether alcohol misuse reduced at the six month follow-up but there will be no comparison/control group.

The findings from this pilot study will be used to inform future programming and research in Zambia and other LMIC to implement screening, brief intervention, and referral to treatment (SBIRT) programs for alcohol use in HIV care.
