A 6-month washout period will be included immediately after the intervention start date to allow clients time to participate in the Comprehensive Adherence Resource and Empowerment Support (CARES) intervention before they are included in the intervention delivery period assessments. The primary outcome will be at the clinic-level as the proportion of AGYW per clinic continuing on any PrEP product.

Originally developed for a clinical trial setting, CARES has shown promising results in enhancing effective PrEP use through a structured mix of counseling, SMS\u002Fphone calls, and peer support for daily oral PrEP and the PrEP ring. However, its resource-intensive design requires adaptation for routine public health settings to ensure feasibility, fidelity, acceptability, and effectiveness. This adapted intervention will be tailored with input from AGYW, PrEP providers, and local stakeholders to support sustainable PrEP use and address HIV prevention needs among AGYW. Additionally, it will incorporate injectable PrEP and be modified to suit routine public health contexts.
