Focused Action towards Suppression and Stopping Transmission (FASST) is centered on the study of persons living with HIV (PLWH) who attend New York City’s (NYC) public STD clinics. Specifically, FASST aims to quantify and describe gaps in HIV care among patients newly diagnosed with HIV at STD clinics, as well as clinic attendees with previously diagnosed HIV who are in need of linkage or re-linkage to HIV primary care. In addition, the study is focused on assessing patient and provider perspectives about the challenges associated with current procedures for referring HIV-diagnosed patients to HIV primary care, and gauging the feasibility of providing STD clinic medical providers with access to data from the NYC Department of Health and Mental Hygiene (DOHMH) HIV Surveillance Registry to identify STD clinic attendees previously diagnosed with HIV who may need assistance accessing or re-accessing HIV primary care. The Bureaus of HIV and STD Control and Prevention at the New York City Department of Health and Mental Hygiene are partners in this study.
