This application is being submitted in response to PA-20-272 as an administrative supplement to DP2DA053720-01 (PI: Tookes). The T-SHARP (Telehealth Solution to HIV and Addiction-Related Problems) trial will study the efficacy of the Tele-Health concieRge intervention in 2 low barrier clinics operated within academic medical centers, University of Miami/Jackson Health System and University of South Florida/Tampa General Hospital. The aims of this administrative supplement are 1) to expand the T-SHARP trial of the Tele-Health concieRge intervention to a third site in Florida with a high prevalence of PWID with HIV and 2) to examine implementation determinants to identify appropriate implementation strategies to facilitate implementation of the Tele-Health concieRge intervention within a new contextual environment (a Federally Qualified Health Center based low barrier clinic). The third site will expand the existing trial to three of the seven Ending the HIV Epidemic jurisdictions in Florida (Miami-Dade, Hillsborough, and Broward Counties). This expansion of trial sites and study of the intervention implementation in a new context will ensure the study meets enrollment targets and that the intervention is feasible in varying low barrier clinic environments.
