Brief Summary
The study's aim is to implement a home-based PrEP (HB-PrEP) monitoring system (self-collected blood and extragenital specimens at home and telehealth follow-up) into a large, urban sexual health clinic while also evaluating the program's clinical effectiveness. Study participants will self-collect blood specimens using Tasso devices, which are currently designated as FDA Class 2 exempt medical devices (similar to a medical lancet). This study will be integrated into King County's Ending the HIV Epidemic plan and generate data to inform refinement, adaptation and scale-up of future HB-PrEP programs. Specific research aims are to:
- 1.Conduct a hybrid randomized trial to compare the impact of a HB-PrEP program versus standard of care (routine in-clinic monitoring) on PrEP retention over time and use mixed-methods assessments to define the factors that influence HB-PrEP implementation. Hypothesis: HB-PrEP will increase PrEP retention rates by \>10% at 18 months and 60% of those offered HB-PrEP will use it for over half of visits.
- 2.Perform a cost analysis of the HB-PrEP implementation strategy compared to standard care. Hypothesis: HB-PrEP cost will fall within the HIV prevention budget and be affordable with comparable costs to SOC.
- 3.Develop a qualitative tool to engage healthcare stakeholders and determine the wider scalability of HB-PrEP.

Study Arms (2)
Standard care
NO INTERVENTIONPatients will receive standard PrEP care in the clinic including in-person visits for triannual (every 4 months) HIV \& STI screening and comprehensive sexual health care.
Home-based care
EXPERIMENTALPatients will have the option to complete their PrEP care from home including 1) self-collection of blood specimens for HIV, syphilis and creatinine; 2) self-swabs for extragenital GC/CT screening; and 3) telehealth follow-up. A maximum of two triannual follow-up visits per year may be conducted remotely; one visit per year must be in person. Participants also have the option to attend visits in person and are otherwise eligible to continue receiving comprehensive sexual health services in the clinic.
