Developing, Evaluating, and Disseminating Definitions for Syndromic Surveillance in Public Health Practice: A Guidance Document

This document, released February 18, 2019, focuses on several key areas related to syndrome definition creation, including the basics behind a syndrome definition, steps to build a syndrome, evaluation of a new (or old) definition, and dissemination.

Use of Diagnosis Code in Mental Health Syndrome Definition

Between 2006 and 2013, the rate of emergency department (ED) visits related to mental and substance use disorders increased substantially. This increase was higher for mental disorders visits (55 percent for depression, anxiety or stress reactions and 52 percent for psychoses or bipolar disorders) than for substance use disorders (37 percent) visits. This increasing number of ED visits by patients with mental disorders indicates a growing burden on the health-care delivery system.

Exploring the Value of Learned Representations for Automated Syndromic Definitions

Comprehensive medical syndrome definitions are critical for outbreak investigation, disease trend monitoring, and public health surveillance. However, because current definitions are based on keyword string-matching, they may miss important distributional information in free text and medical codes that could be used to build a more general classifier. Here, we explore the idea that individual ICD codes can be categorized by examining their contextual relationships across all other ICD codes.

A proposed SyS Case Definition for Opioid Overdose Related ED visits- an evaluation in three regions

Opioid ODs have been rising globally and nationally. The death rate from ODs in the United States has increased 137% since 2000, including a 200% increase of OD deaths involving opioids1. The pilot project, a collaboration across 3 states, allowed information sharing with Syndromic surveillance (SyS) partners across jurisdictions, such as sharing a standard SyS case definition and verifying its applicability in each jurisdiction. This is a continuation of the work from an initial pilot project presented during the ISDS Opioid OD Webinar series.

Assessment of a Surveillance Case Definition for Heroin Overdose in Emergency Medical Services Data

In 2016, the Centers for Disease Control and Prevention funded 12 states, under the Enhanced State Opioid Overdose Surveillance (ESOOS) program, to utilize state Emergency Medical Services (EMS) and emergency department (ED) syndromic surveillance (SyS) data systems to increase timeliness of state data on drug overdoses. A key aspect of the ESOOS program is the development and validation of case definitions for drug overdoses for EMS and ED SyS data systems.

Assessing Definitions of Heroin Overdose in ED & EMS Data Using Hospital Billing Data

In 2016, the Centers for Disease Control and Prevention funded 12 states, under the Enhanced State Opioid Overdose Surveillance (ESOOS) program, to utilize state Emergency Medical Services (EMS) and emergency department syndromic surveillance (SyS) data systems to increase timeliness of state data on drug overdose events. An important component of the ESOOS program is the development and validation of case definitions for drug overdoses for EMS and ED SyS data systems with a focus on small area anomaly detection.

Syndrome Definition Committee (SDC)

MISSION

The mission of the Syndrome Definition Committee (SDC) is to create, evaluate, and refine syndrome definitions, link users with similar syndrome definition needs, and create documentation along the way. We seek to be a resource for collaboration and best practices in the syndrome definition creation process.

RESOURCES

Meetings will occur the first Wednesday of each month from 1-2 PM EST

A Syndrome Definition Validation Approach for Zika Virus

In 2016, the World Health Organization declared Zika virus a global public health emergency. Zika infection during pregnancy can cause microcephaly and other fetal brain defects. To facilitate clinicians’ ability to detect Zika, various syndrome definitions have been developed. 

Objective

To develop and validate a Zika virus disease syndrome definition within the GUARDIAN (Geographic Utilization of Artificial Intelligence in Real-Time for Disease Identification and Alert Notification) surveillance system.

Development of Syndrome Definitions for Acute Unintentional Drug and Heroin Overdose

Nationally, deaths due to opioid overdose have continually increased for the past 15 years . Deaths specifically related to heroin increased more than four-fold between 2002 and 2014. Hospital inpatient discharge data provide information on non-fatal overdoses, but include a significant lag in reporting time. Syndromic ED visit data provide near real-time identification of public health issues and can be leveraged to inform public health actions on the emerging threat of drug overdose.

ED Visits Related to Marijuana Exposures in the Denver Metropolitan Area of Colorado

Assessing health disparities and access to healthcare has been an important issue for emergency preparedness and response efforts in the Denver metropolitan area. There have been several high profile MJ-related illness outbreaks in the US over the past 2 years. The legalization and retail sale of recreational MJ in Colorado necessitates enhanced surveillance for adverse effects from MJ use.
