Evaluating the Role of Peers to Reduce Substance Use Stigma and Improve HIV Care Outcomes in South Africa

South Africa has the most people living with HIV in the world, many of whom use alcohol and other drugs. Alcohol and other drug use is associated with worse HIV care engagement, contributing to increased HIV-related morbidity and mortality.

Healthcare worker stigma towards alcohol and other drug use is associated with poorer treatment of patients who use substances and worse patient engagement in HIV care. There is evidence that healthcare workers in this setting, including community health workers who play a central role in re-engaging patients who are lost to follow-up from HIV care, exhibit stigmatizing behaviors towards HIV patients who use substances.

Peer recovery coaches (PRCs) are trained individuals with lived substance use recovery experience who are integrated into healthcare teams. Healthcare workers who work with PRCs have sustained contact with a person with lived substance use experience, which is associated with lower stigma. In the United States, preliminary research has demonstrated that PRCs can be successfully integrated into healthcare teams, and that PRC contact is associated with increased patient engagement in healthcare. Yet, a PRC model has not yet been tested in South African HIV care.

Therefore, the purpose of this study is to examine the preliminary implementation and effectiveness of integrating a PRC model into existing teams of healthcare workers who are tasked with re-engaging patients in HIV care through community-based primary care teams. In a type 1, hybrid effectiveness-implementation trial, and comparing a healthcare worker team that works with a PRC to one that does not, the investigators will primarily assess the rate of patient re-engagement in care and implementation (i.e., feasibility, acceptability) of the model. Healthcare worker stigma towards patients living with HIV who use substances will also be measured.
