A Systematic Review of Interventions that Promote Frequent HIV Testing

As of 2017, the Centers for Disease Control and Prevention (CDC) HIV testing guidelines recommend that those at increased risk for HIV are tested two to four times per year. Evidence-based interventions that promote frequent and repeated testing remain sparse. We conducted a systematic review to: (1) identify frequent testing interventions; and (2) determine which were successful in increasing frequent testing rates. We searched PubMed, PsycINFO, Web of Science, Embase, and CINAHL for peer-reviewed articles published between January 1, 2010 and September 30, 2017. Ten studies met inclusion criteria. Operationalization of frequent HIV testing varied widely across studies. Four interventions involved text message reminders for HIV testing, three involved community-based testing, two self-testing, and one rapid testing. Text message reminder interventions were most successful in increasing rates of frequent HIV testing. Future research should standardize frequent testing measurement to allow for more robust comparisons of intervention efficacy.
