Emergency Department Chief Complaint Versus Discharge Diagnosis for Tracking Disease Measures

ESSENCE is a web-based syndromic surveillance system utilized by DHMH to detect and track outbreaks, suspicious patterns of illness, public health emergencies, and biological threats. ESSENCE ED chief complaint data is collected daily from 47 emergency departments in Maryland (all 45 acute care hospitals and 2 freestanding emergency medical facilities). A chief complaint in ESSENCE is a free text field that lists the patient’s reason for the ED visit upon arrival at the hospital.

Since its inception, ESSENCE has been a vital tool for DHMH, providing continuous situational awareness for public health policy decision makers.
