IntroductionEffective strategies to increase pre-exposure prophylaxis (PrEP) uptake and continuation among adolescent girls and young women (AGYW) who engage in sex work or transactional sex are sparsely reported. We aimed to describe the available evidence on strategies for improving the uptake and continuation of PrEP among AGYW who engage in sex work or transactional sex, or otherwise are at high risk of acquiring HIV, and report their implementation outcomes.MethodPubMed, Embase, CINAHL and Global Health were searched for studies describing strategies to increase uptake and continuation of PrEP for HIV prevention among AGYW at high risk of acquiring HIV in low-income and middle-income countries. Two independent reviewers screened citations for inclusion and performed data abstraction. Proctor’s framework was used to report the implementation outcomes of the interventions.ResultWe identified 1046 citations, and reviewed 69 full-text documents, of which we included 11 in the scoping review. A social marketing campaign was used in one study to create demand for PrEP. A decision support tool was used in one study to improve PrEP initiation. SMS reminders (two studies), drug-level feedback (two studies), peer group support (one study) and conditional economic incentives (one study) were used to improve PrEP continuation. Five studies reported adoption outcomes, two of which were high. Four studies reported sustainability outcomes; these were low or moderate. One study found private youth-friendly clinics a better fit for AGYW PrEP delivery compared with public hospitals, and prescription of PrEP by non-study staff in the hospital facility was low.ConclusionMultiple promising interventions have been used to deliver PrEP to AGYW at high risk of acquiring HIV; however, more information is needed to understand how these interventions would likely perform at scale outside of a research context.
