The Potential of Syndromic Surveillance
+ Provide timely and actionable ED visit data at the state and local level
+ Detect trends, clustering, and changing patterns of ED visit data

Syndrome Definition Collaborators + CDC Division of Violence Prevention recently developed a suite of firearm injury
definitions in collaboration with colleagues from: • The National Syndromic Surveillance Program• Their community of practice which is now led by CSTE • And several local and state health departments were important collaborators, particularly
the Houston Health Department and the New York City Department of Health and Mental Hygiene, who both had existing case definitions we were able to build upon.

LimitationsLimitations of Syndromic Surveillance in Monitoring Firearm Injuries
+Results are not generalizable to facilities not participating in NSSP
+Healthcare facility participation in NSSP can vary across months.
+Data on patient demographics, including race/ethnicity, incomplete
+Data transmitted to NSSP in near real-time and not considered finalized data sets
