Peer Approaches to Improve HIV Care Cascade Outcomes: a Scoping Review Focused on Peer Behavioral Mechanisms

AbstractPurpose of ReviewThere are three main components of peer-based approaches regardless of type: education, social support, and social norms. The purpose of this scoping review was to examine evidence in the literature among peer-based interventions and programs of components and behavioral mechanisms utilized to improve HIV care cascade outcomes.Recent FindingsOf 522 articles found, 40 studies were included for data abstraction. The study outcomes represented the entire HIV care cascade from HIV testing to viral suppression. Most were patient navigator models and 8 of the studies included all three components. Social support was the most prevalent component. Role modeling of behaviors was less commonly described.SummaryThis review highlighted the peer behavioral mechanisms that operate in various types of peer approaches to improve HIV care and outcomes in numerous settings and among diverse populations. The peer-based approach is flexible and commonly used, particularly in resource-poor settings.
