Background: In Africa, the delivery of HIV pre-exposure prophylaxis (PrEP) at public healthcare clinics is challenged by understaffing, overcrowding, and HIV-associated stigma, often resulting in low PrEP uptake and continuation among clients. Giving clients the option to refill PrEP at nearby private pharmacies, which are often more convenient and have shorter wait times, may address these challenges and improve PrEP continuation.
Methods: This mixed methods study used an explanatory sequential design. At two public clinics in Kiambu County, Kenya, clients ≥ 18 years initiating PrEP were given the option to refill PrEP at the clinic where they initiated for free or at one of three nearby private pharmacies for 300 Kenyan Shillings (~ $3 US Dollars). The providers at these pharmacies (pharmacists and pharmaceutical technologists) were trained in PrEP service delivery using a prescribing checklist and provider-assisted HIV self-testing, both with remote clinician oversight. Clients were followed up to seven months, with scheduled refill visits at one, four, and seven months. The primary outcomes were selection of pharmacy-based PrEP refills and PrEP continuation. Following pilot completion, 15 in-depth interviews (IDIs) with clients who refilled PrEP were completed. We used descriptive statistics and thematic analysis to assess study outcomes.
Results: From November 2020 to November 2021, 125 PrEP clients were screened and 106 enrolled. The majority (59%, 63/106) of clients were women and the median age was 31 years (IQR 26-38 years). Over 292 client-months of follow-up, 41 clients (39%) refilled PrEP; only three (3%) at a participating pharmacy. All clients who completed IDIs refilled PrEP at clinics. The reasons why clients did not refill PrEP at pharmacies included: a preference for clinic-delivered PrEP services (i.e., pre-existing relationships, access to other services), concerns about pharmacy-delivered PrEP services (i.e., mistrust, lower quality care, costs), and lack of knowledge of this refill location.
Conclusions: These findings suggest that clients who initiate PrEP at public clinics in Kenya may have already overcome barriers to clinic-delivered PrEP services and prefer PrEP access there. To reach new populations that could benefit from PrEP, a stand-alone model of pharmacy-delivered PrEP services may be needed.
