Utilization of ESSENCE in the Cloud for Enhanced Surveillance during the 2012 NATO Summit

Electronic public health surveillance serves an especially important function during mass events. Megan Patel, from the Cook County Department of Public Health (CCDPH), will discuss the use of the cloud-based ESSENCE system for situational awareness during the 2012 NATO Summit in Chicago, IL. This webinar will highlight improved functionality obtained via the cloud-based version of ESSENCE, as well as provide a real-life example of utilization.

The webinar will cover:

Hierarchical Filtering of ESSENCE for Routine, Distributed Disease Monitoring by the Veterans Health Administration

The VA has employed ESSENCE for health monitoring since 2006 [1]. Epidemiologists at the Office of Public Health (OPH) monitor the VA population at the national level. The system is also intended for facility-level monitoring to cover 152 medical centers, nearly 800 community-based outpatient clinics (CBOC), and other facilities serving all fifty states, the District of Columbia, and U.S. territories. For the entire set of facilities and current syndrome groupings, investigation of the full set of algorithmic alerts is impractical for the group of monitors using ESSENCE.

Monitoring and auditing the transfer of syndromic surveillance data to ensure data completeness

The electronic surveillance system for the early notification of community-based epidemics (ESSENCE) is the web-based syndromic surveillance system utilized by DHMH. ESSENCE utilizes a secure, automated process for the transfer of data to the ESSENCE system. Data sources in the Maryland ESSENCE system include emergency department (ED) chief complaints, poison control center calls, over-the-counter (OTC) medication sales, and pharmaceutical transaction data (for certain classes of anti-bacterial and anti-viral medication).

The Evolution of ESSENCE

In development for over fourteen years, ESSENCE is a disease surveillance system utilized by public health stakeholders at city, county, state, regional, national, and global levels. The system was developed by a team from the Johns Hopkins University Applied Physics Laboratory (JHU/APL) with substantial collaborations with the US Department of Defense Global Emerging Infections Surveillance and Response System (DoD GEIS), US Department of Veterans Affairs (VA), and numerous public health departments.

Florida’s ESSENCE system - from syndromic surveillance to routine epidemiologic analysis across syndromic and non-syndromic data sources

Federal laws and national directives have focused attention on the development of more robust biosurveillance systems intended to detect events of public health interest in a timelier manner. Presidential Decision Directive 21 calls for integrated biosurveillance data, enhanced clinician awareness, and an epidemiologic surveillance system with sufficient flexibility to tailor analyses to new syndromes and emerging diseases. In 2007, a statewide syndromic surveillance system (ESSENCE) was implemented and hospitals were recruited to participate.

Maryland ESSENCE expansion to incorporate prescription medication data

Maryland has a powerful syndromic surveillance system, ESSENCE, which is used for the early detection of disease outbreaks, suspicious patterns of illness, and public health emergencies. ESSENCE incorporates traditional and nontraditional health indicators from multiple data sources (emergency department chief complaints, over-the-counter (OTC) medication sales, and poison control center data).

Biosurveillance applications for resource-limited settings: open ESSENCE and ESSENCE desktop edition

More than a decade ago, in collaboration with the U.S. Department of Defense, the Johns Hopkins University Applied Physics Laboratory (JHU/APL) developed the Electronic Surveillance System for the Early Notification of Community-based Epidemics (Enterprise ESSENCE), which is currently used by federal, state and local health authorities in the US.

HAIISS Data Warehouse (HDW)FA new data access architecture for ESSENCE in the VA

The data elements required for the proper functionality of VA’s ESSENCE system are all currently available within VA’s 128 VistA systems. These data are made available to VA’s ESSENCE system via a series of complicated MUMPS extraction routines, multiple data transformations crossing multiple servers, networks, operating systems and HL7-parsing routines on a daily interval. With recent changes emerging in VA’s information technology infrastructure, a new data architecture supporting ESSENCE’s surveillance capabilities is becoming possible.

Utilization of Florida poison control data and Emergency Department chief complaint data to identify clusters of carbon monoxide poisoning

The Florida Department of Health (FDOH) previously monitored Florida Poison Information Center (FPICN) data for timely detection of increases in carbon monoxide (CO) exposures before, during, and after hurricanes. Recent analyses have noted that CO poisonings have also increased with generator use and improper heating of homes during cold winter months in Florida. Similarly, increases in CO poisoning cases related to motor vehicles have been observed during summer months.

Components of Inter-Hospital Variability in Chief Complaints Assigned to a Gastrointestinal Syndrome

Patient’s chief complaint (CC) is often used for syndromic surveillance for bioterrorism and outbreak detection, but little is known about the inter-hospital variability in the sensitivity of this method. Objective: Our objective was to characterize the variability of a gastrointestinal (GI) CC text-matching algorithm.
