ESSENCE: Free Text Query Negation

Free text queries are performed by ESSENCE users very often. And increasingly, those free text queries are incorporating negation terms that allow the users to find case definitions when certain terms are not present. This video attempts to explain some of the special cases where negation in free text queries may be confusing for users. The video will mention some features in ESSENCE that you may not be familiar with like the Explain Query button and Advanced Query Tool (AQT).

ED and poison center surveillance for the Great American Solar Eclipse in Oregon

Oregon’s statewide syndromic surveillance system (Oregon ESSENCE) has been operational since 2012. Non-federal emergency department data (and several of their associated urgent care centers) are the primary source for the system, although other data sources have been added, including de-identified call data from OPC in 2016. OPHD epidemiologists have experience monitoring mass gatherings and have a strong relationship with OPC, collaborating on a regular basis for routine and heightened public health surveillance.

Using Syndromic Surveillance Alert Protocols for Epidemiologic Response in Georgia

DPH uses its State Electronic Notifiable Disease Surveillance System (SendSS) Syndromic Surveillance (SS) Module to collect, analyze and display results of emergency department patient chief complaint data from hospitals throughout Georgia.

Objective

Describe how the Georgia Department of Public Health (DPH) uses syndromic surveillance to initiate review by District Epidemiologists (DEs) to events that may warrant a public health response (1).

Characterizing Fentanyl-Associated Mortality using the Literal Causes of Death

In October 2015, the Centers for Disease Control and Prevention (CDC) released health advisory #384 to inform people about increases in fentanyl fatalities. Florida’s statewide syndromic surveillance system, Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE-FL), captures electronic death record data in near real time which allows for the monitoring of mortality trends across the state.

Tracking Health Effects of Wildfires: The Oregon ESSENCE Wildfire Pilot Project

Wildfires occur annually in Oregon, and the health risks of wildfire smoke are well documented1. Before implementing syndromic surveillance through Oregon ESSENCE, assessing the health effects of wildfires in real time was very challenging. Summer 2015 marked the first wildfire season with 60 of 60 eligible Oregon emergency departments (EDs) reporting to ESSENCE.

Using Syndromic Surveillance to Rapidly Describe the Early Epidemiology of Flakka Use in Florida, June 2014 – August 2015

Syndromic surveillance has historically been used to track infectious disease, but in recent years, many jurisdictions have utilized the systems to conduct all hazards surveillance and provide situational awareness with respect to previously identified issues. Flakka is a synthetic drug (class: cathinones) that recently has been featured in the media. Flakka is a stimulant that causes delusions, aggression, erratic behavior, a racing heart and sometimes death. Two specific counties (one in Florida and one in Kentucky) have been at the center of this emerging epidemic.

Analysis of ED and UCC Visits Related to Synthetic Marijuana in ESSENCE-FL, 2010-2015

Illnesses related to synthetic marijuana use have been reported in many states, including Florida. Because these visits can present with a variety of symptoms, as well as be attributed to numerous diagnosis codes, it can be difficult to identify and quantify these visits. The Electronic Surveillance System for the Early Notification of Community-based Epidemics in Florida (ESSENCE-FL) receives chief complaint (CC) and discharge diagnosis (DD) data as free text allowing uncommon or new terms to be searched for within each patient visit.
