Retention in HIV care and viral suppression rates remain suboptimal, especially among people with HIV (PWH) facing complex barriers to care such as mental health conditions, substance use disorders, and housing insecurity. The Center for Adherence, Retention, and Engagement Support (CARES) program utilizes an interdisciplinary team that delivers integrated services in a drop-in setting to provide individualized care to PWH with complex psychosocial needs. We describe the CARES program and evaluate its effectiveness in retaining patients in care to achieve virological suppression. We characterized 119 referrals of PWH experiencing homelessness, mental health conditions, and substance use disorders to CARES between 2011 and 2017, and collected data for a 24-month observation period through 2019. Outcomes of patients who participated in CARES were compared with those who were referred but did not participate. The primary outcome was viral suppression (<200 copies/mL) at least once during 2-year follow-up. Retention in care (≥2 completed medical visits ≥90 days apart in each year post-referral) was a secondary outcome. Of 119 PWH referred to CARES, 59 participated with ≥2 visits. Those who participated in CARES were more likely to achieve viral suppression [adjusted odds ratio (aOR) 3.50, 95% confidence interval (CI) 1.19-10.32] and to be retained in care (aOR 3.73, 95% CI 1.52-9.14) compared with those who were referred but did not participate. This analysis found that the CARES program improved retention in care and viral suppression among PWH with complex psychosocial needs and suggests that it may represent a useful model for future programming.
