A Capacity-Strengthening Intervention to Support HIV Pre-exposure Prophylaxis (PrEP) Awareness-Building and Promotion by Frontline Harm Reduction Workers in Baltimore, Maryland: A Mixed Methods Evaluation

Abstract

Pre-exposure prophylaxis (PrEP) is a promising but underutilized HIV prevention tool among people who inject drugs (PWID). We developed and piloted an intervention to bolster PrEP promotion competencies among frontline harm reduction workers (FHRW) serving PWID clients in Baltimore, Maryland. Between December 2021 and February 2022, we developed and facilitated four trainings, which included didactic and practice-based/role-playing components, with 37 FHRW from four organizations. FHRW completed three structured surveys (pretest, posttest, 6-week posttest) and in-depth interviews ( n = 14) to measure changes in PrEP promotion competencies attributable to training participation. PrEP knowledge and self-efficacy increased significantly ( p < 0.001) from pretest to posttest, sustained through 6-week posttest. The proportion of FHRW discussing PrEP with clients doubled during the evaluation period (30–67%, p = 0.006). Feeling empowered to discuss PrEP and provision of population-tailored PrEP information were facilitators of PrEP promotion, while limited client interaction frequency/duration, privacy/confidentiality concerns, and anticipated PrEP stigma by clients inhibited PrEP promotion. Our capacity-strengthening intervention successfully increased PrEP knowledge, self-efficacy, and promotion among FHRW, affirming the adaptability and feasibility of integrating our training toolkit into FHRW practice across implementation settings.
