Comparing and Contrasting Two ESSENCE Syndrome Definition Query Methods

The Kansas Syndromic Surveillance Program (KSSP) utilizes the ESSENCE v.1.20 program provided by the National Syndromic Surveillance Program to view and analyze Kansas Emergency Department (ED) data. Methods that allow an ESSENCE user to query both the Discharge Diagnosis (DD) and Chief Complaint (CC) fields simultaneously allow for more specific and accurate syndromic surveillance definitions. As ESSENCE use increases, two common methodologies have been developed for querying the data in this way.

Developing and Validating a Fireworks-Related Syndrome Definition in Kansas

Across the U.S.A., multiple people seek treatment for fireworks-related injuries around the July 4th holiday. Syndromic surveillance in Kansas allows for near real-time analysis of the injuries occurring during the firework selling season. During the 2017 July 4th holiday, the Kansas Syndromic Surveillance Program (KSSP) production data feed received data from 88 EDs at excellent quality and timeliness. Previous and current firework safety messaging in Kansas is dependent on voluntary reporting from hospitals across the state.

Creation of a Kansas Spring Extreme Weather Syndrome Definition and Unique Records

Kansas storms can occur without warning and have potential to cause a multitude of health issues. Extreme weather preparedness and event monitoring for public health effects is being developed as a function of syndromic surveillance at the Kansas Department of Health and Environment (KDHE). The Syndromic Surveillance Program at KDHE utilized emergency department (ED) data to detect direct health effects of the weather events in the first 9 months of 2016.

Rabies Exposure and PEP - Kansas Department of Health and Environment

This syndrome was created to query NSSP ESSENCE on Rabies Exposure and Rabies PEP S

Syndromic Surveillance System - NSSP ESSENCE

Data source - Emergency Room Visits

Fields used - Chief Complaint History and Discharge Diagnosis History OR CCDD (an ESSENCE-concatenated field of Chief Complaint and Discharge Diagnosis)

Firework Injuries - Kansas Department of Health and Environment

This syndrome was created to query NSSP ESSENCE for KS ED visits related to fireworks, particularly around the United States Independence Day holiday. Legality and slang for firework injuries will vary by region and some terms in this query are fairly region-specific.

Syndromic Surveillance System - NSSP ESSENCE

Data Source - Emergency Room Visits

Fields Used - Chief Complaint History, Discharge Diagnosis History OR CCDD (an ESSENCE-concatenated field of Chief Complaint and Discharge Diagnosis)

Opioid Diagnosis Codes - Adapted from the HCUP Definition - Kansas Department of Health and Environment

This syndrome was created as a way to integrate the H-CUP Opioid-Related Hospital Use definition into ESSENCE. H-CUP is the Healthcare Cost and Utilization Project and we believe their Opioid-Related Hospital Use definition is a great starting point for developing opiate-use syndrome definitions.

Frostbite, Cold Exposure, & Hypothermia** - Kansas Department of Health and Environment

This syndrome was created as a way to monitor Frostbite, Cold Exposure, & Hypothermia in Kansas Emergency Department visits. **Please note that the hypothermia portion of this syndrome was created to ONLY include hypothermia associated with low environmental temperature.

Syndromic Surveillance System - NSSP ESSENCE

Data sources - Emergency Room Visits

Fields Used - CCDD (an ESSENCE-concatenated field of Chief Complaint and Discharge Diagnosis)

Exposure to Forces of Nature (Weather) Diagnosis Codes - Kansas Department of Health and Environment

This syndrome was created to capture cases where the "exposure to forces of nature" diagnosis codes are sent. This was created as a starting place for weather surveillance and should capture all weather-related events that are explicitly stated and diagnosed. Please note that if your region receives a lot of sun, the primary case counts in this syndrome definition will be sunburns. KDHE has uploaded a second similar syndrome that excludes these cases.
