Syndromes

BioSense is a national automated surveillance system designed to enhance the nation's capability to rapidly detect and quantify public health emergencies, by accessing and analyzing diagnostic and prediagnostic health data. The BioSense system currently receives near real-time data from more than 540 civilian hospitals, as well as national daily batched data from over 1100 Department of Defense and Veterans Affairs medical facilities. BioSense maps chief complaint and diagnosis data to 11 syndromes and 78 sub-syndromes. This project was spurred by the recent detection of several clusters with chief complaints containing the term “exposure” only some of which map to current BioSense sub-syndromes. BioSense currently does not have a generic “exposure” sub-syndrome.

 

OBJECTIVE

To identify hospital visits with chief complaints concerning exposures, characterize them, and develop methods for detecting exposure clusters.

We report on a retrospective analysis of gastrointestinal syndrome definitions based on chief complaints and ICD9 diagnosis for gastroenteritis during the 2006-07 season of increased norovirus activity.

This is a cluster of syndromes created to populate an extreme weather myESSENCE tab. The intent was to increase repeatability of our weather surveillance and have something where a user can use the "Change Region" option to select whatever county, or counties, experienced storm activity. This is still a major work-in progress.

All of this as done in NSSP ESSENCE on Emergency Room data. Fields are specified by each syndrome definition.

This syndrome was created to query NSSP ESSENCE on CO Poisoning and Exposure

Kansas just made CO Poisoning a mandatory reportable disease, but this was done so rapidly that hospital didn't have the chance to get reporting measures/alerts in place so many of our CO Poisonings went unreported. This set of queries was created to find these cases through EDs and then educate/remind hospitals of the legislation changes.

Using the chief complaint field from our established syndromic ED system, we developed definitions for potentially preventable oral health visits (OHV) and examined patterns in 2009-2011 data. Under the widest definition, OHV comprised about 1% of ED visits. Adults ages 18 to 29 had markedly higher OHV than other ages, as did certain neighborhoods/EDs. We found more than half of OHV occurred during daytime hours, suggesting opportunities for targeted outreach and education. With some caveats, syndromic ED data provide a useful complement to other oral health surveillance strategies.

Objective

To utilize an established syndromic reporting system for surveil- lance of potentially preventable emergency department (ED) oral health visits (OHV) in New York City (NYC).

Early detection of rarely occurring but potentially harmful diseases such as bio-threat agents (e.g., anthrax), chemical agents (e.g., sarin), and naturally occurring diseases (e.g., meningitis) is critical for rapid initiation of treatment, infection control measures, and emergency response plans. To facilitate clinicians’ ability to detect these diseases, various syndrome definitions have been developed. Due to the rarity of these diseases, standard statistical methodologies for validating syndrome definitions are not applicable.

 

Objective

To develop and test a novel syndrome definition validation approach for rarely occurring diseases.

NYC EDs saw nearly 4 million visits in 2011. Studies have demon- strated that non-urgent visits can account for more than 50% of vis- its to EDs. Designed to provide rapid diagnosis and first-line treatment of serious illness, EDs often function as a primary care site due to their accessibility. Unfortunately, use of EDs for primary care may affect their ability to meet the needs of severely ill patients.

 

Objective

To develop a syndrome classification based on patient chief com- plaint to (1) estimate the proportion of primary care-related emer- gency department (ED) visits in New York City (NYC) hospitals and (2) explore predictors of such visits.

This is a preliminary Chronic Pain-Related Syndrome, created to search relevant ICD10 and a few key terms in emergency department visits in ESSENCE. The codes and terms are specific to non-cancer related chronic pain with exclusions of cases receiving cancer-related ICD10.

ICD10 codes were selected by translating the following ICD9 codes for Chronic Pain contained in this PDF (https://www.cdc.gov/drugoverdose/pdf/pdo_guide_to_icd-9-cm_and_icd-10_c…)

The homelessness syndrome was developed to identify emergency department visits in ESSENCE for patients who are experiencing homelessness or housing insecurity. The syndrome is intended for use with chief complaint, triage notes, and discharge diagnosis codes (ICD-10 CM). The definition heavily relies on diagnosis codes primarily used by non-critical access hospitals and artificial exclusion of critical access facilities should be considered when data are interpreted.

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.
