Adapting a community-based intervention to address social determinants of health influencing pre-exposure prophylaxis services for Black adults in Washington, District of Columbia: A study protocol

Community-based HIV treatment initiation and continuation helps to address social determinants of health (SDOH) barriers to care and increase antiretroviral therapy (ART) uptake and adherence. Similarly, community-based pre-exposure prophylaxis (cbPrEP) services can help address SDOH barriers such as transportation costs and stigma. However, few studies have examined cbPrEP programming in the Washington, District of Columbia (DC) area where more Blacks are disproportionately affected by HIV and have low PrEP uptake. This study aims to adapt and pilot a community-based ART intervention (cbART) intervention for cbPrEP service delivery for Black adults in the Washington, DC area. The adaptation of the cbART intervention will be informed by the ADAPT-ITT framework and the Consolidated Framework for Implementation Research. For Aim 1, in-depth and key informant interviews will be conducted with PrEP program managers at community-based organizations (N = 10), DC health department representatives (N = 8), PrEP providers (N = 10) and current and potential Black PrEP users (n = 24). The interviews will provide an initial assessment of barriers and facilitators to PrEP services and inform the decisions on how to adapt the cbART intervention for cbPrEP services. In Aim 2, we will train and pilot test the cbPrEP intervention for acceptability, feasibility, and appropriateness with Black adults (n = 60). Enrolled participants will complete a survey at baseline and at 45 days post-enrollment. In-depth interviews will be conducted with a subset (N = 16) of participants, those who did not enroll (N = 10) and providers implementing the cbPrEP intervention (N = 8). Alternative strategies to PrEP service delivery are needed to increase PrEP uptake among those most in need in the DC area. If cbPrEP delivery is found to be acceptable, feasible, and appropriate, it could have a significant impact on DC’s Ending the HIV Epidemic efforts and will inform future efforts to investigate the intervention’s efficacy on PrEP uptake and continuation among Black adults in DC.
