Abstract

ILINet is used by sentinel healthcare providers for reporting influenza surveillance data. The Florida Department of Health receives urgent care center data through the ESSENCE syndromic surveillance system from participating facilities, and which can include discharge diagnoses. Seminole County is unique in that its sentinel providers located in four separate urgent care centers report into both systems, and their discharge diagnoses are recorded in ESSENCE. Data from the two systems were therefore compared both among and between the individual sentinel providers in order to identify differences in reporting influenza in ILINet from actual discharge diagnoses for influenza identified through ESSENCE.
