The goal of this study is to measure the implementation and effectiveness of a multicomponent strategy for PrEP for people who are incarcerated at the Dallas County Jail. Specifically, based on a patients risk score on an electronic medical record HIV prediction model, referrals from providers and/or patient self-referrals, a PrEP patient navigator will meet with individuals at the jail to discuss HIV risk, offer HIV/STI testing if not yet completed and offer education around PrEP with referrals to community-based PrEP providers.

The objective of Aim 3 is to deploy the multicomponent strategy that was refined in Aim 2 and evaluate its impact on PrEP implementation and related clinical outcomes using iterative quantitative and qualitative assessments. The investigators' approach will be to utilize the EPIS framework (Exploration, Preparation, Implementation, Sustainment) across the jail-to-community continuum. The investigators will use mixed-methods to evaluate implementation process measures and an interrupted time series design to measure clinical outcomes for PrEP evaluations and linkage, as well as HIV/STI testing and diagnoses. The investigators' expected outcome is to define a feasible, acceptable and effective PrEP implementation strategy for jails.
