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. In this multisite 24-week trial, we randomized PWH reporting untreated unhealthy alcohol use and with phosphatidylethanol (PEth) >20 ng/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 for the past 21 days at week 24. 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% credible interval [CrI]: 0%-33%)] compared with TAU [posterior mean proportion 0.3% (95% CrI: 0%-4%)] [posterior mean treatment effect 9%, (95% CrI: 0%-32%)], the posterior probability of TAU being superior to ISAT + CM was <0.0001. 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. Clinicaltrials.gov (NCT03089320).
