Abstract

Improving patient engagement in HIV care is critical for maximizing the impact of antiretroviral therapy (ART). We conducted a systematic review of studies that used HIV-positive peers to bolster linkage, retention, and/or adherence to ART. We searched articles published and indexed in Pubmed, PsycINFO, and CINAHL between 1996 and 2014. Peers were required to be HIV-positive. Studies were restricted to those published in English. Nine studies with n = 4658 participants met the inclusion criteria. Peer-based interventions were predominantly focused on improving adherence to ART, or evaluations of retention and adherence via viral suppression. Five (56 %) were conducted in sub-Saharan Africa. Overall findings were mixed on the impact of peers on ART adherence, viral suppression, and mortality. While positive effects of peer interventions on improving linkage and retention were found, there were limited studies assessing these outcomes. Additional research is warranted to demonstrate the impact of peers on linkage and retention in diverse populations.
