McCann NC, et al. - Researchers intended to identify costs of recommended initial antiretroviral treatment (ART) regimens in the United States between 2012 and 2018 and the magnitude of cost changes over time. Compared with all other well-resourced countries, including Britain, Australia, and Canada, the United States has the highest ART prices yet the lowest rate of HIV viral suppression (54%). In the United States, high ART costs are among many structural obstacles that lead to poor treatment access and adherence, contributing to suboptimal HIV results.
