Tracking HIV Post-Exposure Prophylaxis using Syndromic Surveillance in NYC Emergency Departments

Introduction HIV post-exposure prophylaxis (PEP) involves taking antiretroviral medication after potential exposure to HIV to reduce the probability of becoming infected. New York State recommends PEP following certain occupational (e.g., needle sticks by healthcare workers) and non-occupational (e.g., sexual and needle-sharing activities) exposures.1 Little information exists on the uptake of PEP for HIV in the United States, particularly with regard to nonoccupational exposures.2 ED data have been used previously to identify occupational PEP visits3 but have not been used extensively to describe trends in PEP visits overall. We aimed to identify HIVrelated PEP visits in NYC EDs to track uptake and inform outreach efforts.
