Implementation of Doxy-PEP in a Diverse Sexual Health Program in Northern Manhattan: The Doxy-Care Study.

This prospective cohort study evaluated the real-world effectiveness of doxycycline postexposure prophylaxis use in reducing bacterial sexually transmitted infections (STIs) within a diverse urban sexual health program. Propensity-matched analyses showed significant STI reductions, particularly in rectal Chlamydia trachomatis infections, among early adopters. Uptake was disproportionately higher in non-Hispanic White individuals and those more engaged in care. Findings emphasize the need for targeted outreach to improve care engagement and equitable access to this STI prevention strategy.
