About this study
Official title: The HOTSPOT Study Hybrid Implementation-effectiveness Study to Optimize HIV Testing and PrEP in a Southern Jail
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Multicomponent strategyBehavioural
Identify patients for HIV/STI testing, engage in discussions around PrEP and navigate patients to PrEP after jail incarceration
| Study group | Role | What they receive |
|---|---|---|
| PrEP navigation | Other | This is a single arm study where people in the Dallas County Jail identified to be at elevated risk for HIV are offered a PrEP navigation visit Receives: Behavioral: Multicomponent strategy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Linkage to PrEP care
Measure the proportion of individuals (of those who stated that they were interested in PrEP and have been released from jail) who attended a clinic visit with a PrEP provider as confirmed by the PrEP patient navigator or through medical record review.
Measured: Within 90 days of release from jail
