4 What is ESSENCE? Electronic Surveillance System for the Early Notification of Community-based Epidemics, ESSENCE – Johns Hopkins UniversityESSENCE Offers excellent slicing and dicing capabilities for analysis Delivers valuable hospital view of data for infection preventionists (IP), others Hospital view allows collaboration with public health while protecting hospital/patient confidentiality

5 Seeks recognition and generates alerts for: –Conditions indicating unusual / unexpected health event may be imminent –Unusual or unexpected number of illnesses or syndromes within a period of time or geographic area –Illness or syndromes in an unusual population Surveillance

6 Purpose of Syndromic Surveillance Early Event Detection (primary) –Prevention measures before diagnosis of unusual cases Facilitates Outbreak Management (secondary) –Case investigation and management –Exposure contact tracing –Exposure source investigation and linking of cases and contacts to exposure sources

7 This system groups acquired data into sets of symptoms that define syndromes and sub- syndromes such as : –Respiratory Influenza-like illness –Gastrointestinal – Neurological Based on traditional sources: –Outpatient ICD-9 codes –Emergency room chief complaints Based on non-traditional sources: –School absenteeism –Over the counter (OTC) sales Syndromic Surveillance:

8 Syndromic surveillance via limited data set: HIPAA-compliant; gathered in software- neutral manner Limited data set Algorithms run on data automatically seeking anomalies Historical hospital data is baseline for analysis Users drill down to investigate
