Success of HIV Treatment May Be Undercounted, New Study Says
Traditional methods of counting patients being treated for HIV may underestimate the success of treatment, a new AHRQ-funded study found. The study examined the HIV continuum of care, which consists of diagnosis, linkage to and retention in care, receipt of antiretroviral therapy and suppression of the virus. Steps in this continuum are typically calculated in a conditional manner, with the number of people completing the prior step serving as the base population for the next step. However, researchers hypothesized, this approach may underestimate the prevalence of viral suppression. In this study, researchers followed 17,140 patients between 2010 and 2012, classifying them as to whether they completed the continuum of care or skipped steps in the process. They found that the virus was suppressed in some patients who had minimal contact with providers. Ignoring this group, researchers said, underestimates the proportion of patients suppressed by 13 percent. The article and abstract, “The HIV Care Continuum: Changes over Time in Retention in Care and Viral Suppression,” were published June 18 in the journal PLOS One.
