A prospective, pilot implementation evaluation of patient-centered differentiated care service. The core components of the multifaceted implementation strategy include: 1) 3-monthly refills, 2) direct-to-pharmacy refill visits, 3) HIV self-testing (HIVST) while waiting for refills, 4) Rapid risk assessment for ongoing risk, adherence, side effect, and acute HIV symptoms. Clinics will implement either: 1) current PrEP patient flow without any change or 2) a pilot differentiated pharmacy-based follow up PrEP care pathway. Clinics will implement only one delivery model thus eliminating risk for confusion in the clinic about delivery models and permitting a full-scale test of the system, since the efficiency in PrEP delivery is in part at the system level, above and beyond the individual client encounter. For this pilot project designed to primarily test delivery efficiency, feasibility and acceptability of direct-to-pharmacy care pathway at systems level using existing public health infrastructure, pilot and control clinics will be of comparable size selected to reflect the implementation nature of the design.

The specific aims are:

Aim 1: To evaluate whether a differentiated care model improves the efficiency of PrEP delivery while resulting in equivalent or better: 1) patient waiting time, 2) early PrEP continuation, and 3) adherence.

Aim 2: Conduct mixed-methods study to understand patient and provider perception, experiences , feasibility and acceptability of a differentiated PrEP delivery model.

Aim 3: Assess the efficiency, cost and cost-effectiveness of a facility-based differentiated PrEP care.
