Abstract
Background
Fewer than 70% of people living with HIV (PLHIV) in the United States have achieved durable viral suppression. To end the HIV epidemic in the United States, clinicians, researchers, and public health practitioners must devise ways to remove barriers to effective HIV treatment. To identify PLHIV who experience challenges to accessing healthcare, we created a simple assessment of social determinants of health (SDOH) among PLHIV and examined the impact of cumulative social and economic disadvantage on key HIV care outcomes.
Methods
We used data from the 2015-2019 Medical Monitoring Project, a yearly cross-sectional survey of PLHIV in the United States (N=15,964). We created a ten-item index of SDOH and assessed differences in HIV care outcomes of missed medical appointments, medication adherence, and durable viral suppression by SDOH using this index using prevalence ratios with predicted marginal means.
Results
Eighty-three percent of PLHIV reported at least one SDOH indicator. Compared to PLHIV who experienced none of the SDOH indicators, people who experienced one, two, three, and four or more SDOH indicators, were 1.6, 2.1, 2.6 and 3.6 as likely to miss a medical appointment in the prior year; 11%, 17%, 20% and 31% less likely to report excellent adherence in the prior 30 days; and, 2%, 4%, 10% and 20% less likely to achieve durable viral suppression in the prior year, respectively.
Conclusions
Among PLHIV, cumulative exposure to social and economic disadvantage impacts care outcomes in a dose-dependent fashion. A simple index may identify PLHIV experiencing barriers to HIV care, adherence, and durable viral suppression in need of critical supportive services.
