Integrated stepped alcohol treatment with contingency management for unhealthy alcohol use among people with HIV: A randomized controlled trial.

Background: We examined the impact of integrated stepped alcohol treatment with contingency management (ISAT+CM) on alcohol abstinence among people with HIV (PWH) and unhealthy alcohol use.

Methods: In this multisite 24-week trial, we randomized PWH reporting untreated unhealthy alcohol use and with phosphatidylethanol (PEth) >20ng/mL to receive ISAT+CM or treatment as usual (TAU). Intervention: Step 1: Social worker-delivered CM; Step 2: Addiction physician management plus motivational enhancement therapy. Participants were advanced to step 2 at week 12 if they lacked evidence of abstinence over the prior 21 days. TAU: Health handout, and for those who met criteria for alcohol use disorder, a referral to substance use treatment. Primary outcome: self-reported abstinence over the past 21 days at week 24.

Results: We enrolled 120 PWH between January 5, 2018 and March 1, 2022. Mean age was 59 years, 96% were men, and 83% were Black. Eight percent were lost to follow-up. In the ISAT+CM group, 87% were advanced to Step 2. The posterior mean proportion of participants with self-reported abstinence at 24 weeks was higher among those randomized to ISAT+CM (posterior mean proportion 9% [95%CrI, 0%, 33%]) compared with TAU (posterior mean proportion 0.3 % [95%CrI, 0%, 4%]) (posterior mean treatment effect 9%, [95%CrI, 1%, 32%], the posterior probability of TAU being superior to ISAT+CM was <0.0001.

Discussion: ISAT+CM delivered in HIV clinics modestly increased self-reported 3-week abstinence among PWH. Our findings indicate a need for more effective treatments to promote abstinence and a potential role for ISAT+CM for reductions in alcohol use.
