Effect of differentiated direct‐to‐pharmacy PrEP refill visits supported with client HIV self‐testing on clinic visit time and early PrEP continuation

: Introduction: Delivery of oral pre‐exposure prophylaxis (PrEP) is being scaled up in Africa, but clinic‐level barriers including lengthy clinic visits may threaten client continuation on PrEP. Methods: Between January 2020 and January 2022, we conducted a quasi‐experimental evaluation of differentiated direct‐to‐pharmacy PrEP refill visits at four public health HIV clinics in Kenya. Two clinics implemented the intervention package, which included direct‐to‐pharmacy for PrEP refill, client HIV self‐testing (HIVST), client navigator, and pharmacist‐led rapid risk assessment and dispensing. Two other clinics with comparable size and client volume served as contemporaneous controls with the usual clinic flow. PrEP continuation was evaluated by visit attendance and pharmacy refill records, and time and motion studies were conducted to determine time spent in the clinics. Dried blood spots were collected to test for tenofovir‐diphosphate (TFV‐DP) at random visits. We used logistic regression to assess the intervention effect on PrEP continuation and the Wilcoxon rank sum test to assess the effect on clinic time. Results: Overall, 746 clients were enrolled, 366 at control clinics (76 during pre‐implementation and 290 during implementation phase), and 380 at direct‐to‐pharmacy clinics (116 during pre‐implementation and 264 during implementation phase). Prior to implementation, the intervention and control clinics were comparable on client characteristics (female: 51% vs. 47%; median age: 33 vs. 33 years) and PrEP continuation (35% vs. 37% at 1 month, and 37% vs. 39% at 3 months). The intervention reduced total time spent at the clinic by 35% (median of 51 minutes at control vs. 33 minutes at intervention clinics; p Conclusions: A client‐centred PrEP delivery approach with direct‐to‐pharmacy PrEP refill visits plus client HIVST significantly reduced clinic visit time by more than one‐third and improved PrEP continuation in public health HIV clinics in Kenya.
INTRODUCTION Oral pre‐exposure prophylaxis (PrEP) is a highly effective HIV prevention strategy [1–3]; however, maximizing access and continuation is a key challenge for optimizing the overall public health impact of [...]
