Barriers to Adolescent PrEP in Western Kenya: An Implementation Sciences Approach

This study pilots the implementation of an intervention (AYA PrEP peer mentors) in increasing knowledge, reducing stigma and increasing uptake and adherence to PrEP among AYA. In low and middle income countries, peer mentor interventions to improve health behaviors are well supported by evidence, and used extensively by the AMPATH programs as a best practice. We are examining the implementation (e.g. training, reach, acceptability) rather than the effectiveness of this intervention. The study has been approved by both the IU IRB and the Moi University Institutional Research Ethics Committee.

The intervention will engage five PrEP focused peer-mentors, one stationed at Moi Teaching and Referral Hospital Reproductive Health Clinic; one from the Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) community, and three from specified tertiary institutions in Eldoret, Kenya (Eldoret Medical Training College, The University of Eldoret, Eldoret Polytechnic) to focus on college students. These peer mentors will be paid a monthly stipend, and their roles will be to: (1) Hold one on one discussions with target AYA on PrEP; (2) To hold group discussions on PrEP with the target AYA; (3) To champion for PrEP promotion and provision by healthcare workers; and (4) To do outreach-work, adherence support and clinic reminders for those on PrEP. Peer mentors received PrEP and peer mentor training adapted from an existing USAID curriculum, as well as training in research procedures. Peer mentors will complete a pre-and post-training survey to measure their efficacy and knowledge on HIV and PrEP.

The EHR aspect of the study will involve extraction of data before and during the peer mentor intervention. The data extraction will include de-identified information from visits for PrEP initiation and PrEP maintenance among AYA in Uasin Gishu County. We will collect the socio-demographic and clinical data of PrEP initiation and maintenance visits among AYA aged 15-24 years. The qualitative data aspects will involve FGDs with 1) the PrEP focused peer mentors, 2) PrEP AYA initiators, and 3) Healthcare workers. This FGDs will explore the acceptability, feasibility and adaption of the AYA PrEP peer mentor program. The quantitative data will also include PrEP peer mentors completing a tracking form that describes characteristics of the outreach interaction, including the total # people, topics discussed, and whether the group was a high risk group (e.g. LGBTQ, pregnant/parenting, discordant relationship). No personal identifiers or identifiable characteristics of individuals will be collected, and a waiver of informed consent has been granted.

For data analysis to look at effectiveness, the number of visits for PrEP initiation and maintenance in the system for a 3 month period before the intervention starts will be compared to the number of visits for PrEP initiation during the intervention. De-identified EHR data will be used. To qualitatively examine the effect of the intervention on stigma and barriers, FGDs will be conducted with AYA, healthcare workers, and peer mentors at the end of the intervention. To examine the implementation of the intervention, (1) the number of of participants overall, (2) the total number of interactions/outreach, (3) the total number of interactions/outreach that include someone from higher HIV risk groups, and (4) the topics of the outreach interaction will be tracked using run charts.
