Respiratory Syndrome in the Netherlands in Relation to Pathogen Activity

Syndromic surveillance may be suited for detection of emerging respiratory disease elevations that could pass undiagnosed. The syndromes under surveillance should then retrospectively reflect known respiratory pathogen activity. To validate this for respiratory syndromes we analyzed dutch medical registration data from 1999-2003 (national hospital discharge diagnoses and causes of death). We assume that syndromes with a good reflection of pathogen activity have the potential ability to reflect unexpected respiratory pathogen activity in prospective surveillance.

Improving System Ability to Identify Symptom Complexes in Free-Text Data

Text-based syndrome case definitions published by the Center for Disease Control (CDC)1 form the basis for the syndrome queries used by the North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT). Keywords within these case definitions were identified by public health epidemiologists for use as search terms with the goal of capturing symptom complexes from free-text chief complaint and triage note data for the purpose of early event detection and situational awareness.

Monitoring Febrile Syndromes from Chief Complaints: Is the Information There?

There exists no standard set of syndromes for syndromic surveillance, and available syndromic case definitions demonstrate substantial heterogeneity of findings constituting the definition. Many syndromic case definitions require the presence of a syndromic finding (e.g., cough or diarrhea) and a fever.

Reverse Engineering of a Syndrome Definition for Influenza

We report here on the use of the North Carolina Bioterrorism and Emerging Infection Prevention System (NC BEIPS, to reverse engineer a syndrome definition of influenza for the purpose of influenza surveillance.

The NGram CC Classifier: A Novel Method of Automatically Creating CC Classifiers Based on ICD9 Groupings

Syndromic surveillance of emergency department (ED) visit data is often based on computer algorithms which assign patient chief complaints (CC) to syndromes. ICD9 code data may also be used to develop visit classifiers for syndromic surveillance but the ICD9 code is generally not available immediately, thus limiting its utility. However, ICD9 has the advantages that ICD9 classifiers may be created rapidly and precisely as a subset of existing ICD9 codes and that the ICD9 codes are independent of the spoken language.

The Value of Patient Reports in Syndrome Assignment

Of critical importance to the success of syndromic surveillance systems is the ability to collect data in a timely manner and thus ensure rapid detection of disease outbreaks. Most emergency department-based syndromic surveillance systems use information rou-tinely collected in patient care including patient chief complaints and physician diagnostic coding. These sources of data have been shown to have only limited sensitivities for the identification of cer-tain syndromes. Another potential source of information, which has not been previously studied, is the patient.

Beyond Detection: Attack Characterization with Syndromic and Clinical Data

Most research in syndromic surveillance has emphasized early detection, but clinical diagnosis of the index case will tend to occur before detection by syndromic surveillance for certain types of outbreaks [1]. Syndromic surveillance may, however, still play an important role in rapidly characterizing the outbreak size because there will be additional non-diagnosed symptomatic cases in the medical system when the index case is identified.

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)

Hypothermia/Cold Exposure - Idaho Division of Public Health

This query is used to assess trends in hypothermia or cold exposure in emergency department visits in ESSENCE. The query captures cold exposure, hypothermia, and frost bite using chief complaint, triage note, and discharge diagnosis code (ICD-10CM). The query does not exclude hypothermia related to an underlying medical condition.

All Traffic Related, Washington State Department of Health, 2018

Objective: Capture all traffic-related injuries presenting to the emergency room regardless of intent or vehicle type to allow monitoring of long-term trends in traffic-related injuries as well as short-term aberrations due to holiday, events, weather.

Syndromic Surveillance System: ESSENCE

Data sources: Emergency Department Visits

Fields queried: SubSyndrome Free Text, Chief Complaint History, Admit Reason Code, Admit Reason Combo, Discharge Diagnosis History
