摘要:HIV post-exposure prophylaxis (PEP) prescriptions are not uniformly monitored in the United States. We developed a method to identify PEP-related visits in New York City emergency departments (EDs). Using ED data, we observed a threefold increase in PEP-related visits to NYC EDs from 2002-2013. 73% of PEP-related visits were among males, and 45% among adults ages 25-34 years. Incorporation of this method of PEP monitoring in the NYC syndromic surveillance system will be used to observe trends and inform HIV outreach efforts.
