HIV Self-Testing for Efficient PrEP Delivery Is Highly Acceptable and Feasible in Public Health HIV Clinics in Kenya: A Mixed Methods Study.

HIV self-testing (HIVST) has the potential to reduce barriers associated with clinic-based preexposure prophylaxis (PrEP) delivery. We conducted a substudy nested in a prospective, pilot implementation study evaluating patient-centered differentiated care services. Clients chose either a blood-based or oral fluid HIVST kit at the first refill visit. Data were abstracted from program files and surveys were administered to clients. We purposively sampled a subset of PrEP clients and their providers to participate in in-depth interviews. We surveyed (n = 285). A majority (269/285, 94%) reported HIV risk. Blood-based HIVST was perceived as easy to use (76/140, 54%), and (41/140, 29%) perceived it to be more accurate. Oral fluid-based HIVST was perceived to be easy to use (95/107, 89%), but almost all (106/107, 99%) perceived it as less accurate. HIVST improved privacy, reduced workload, and saved time. HIVST demonstrates the potential to streamline facility-based PrEP care in busy African public health facilities.
