UPDATED: Syndromic Surveillance 101 - An Introductory Course in Syndromic Surveillance

An Online Training Course

Ever wonder what syndromic surveillance is? How it is applied? This introduction to syndromic surveillance answers your questions and gives you a foundation for understanding how surveillance is used by public health professionals to understand health threats.

 

This video introduces the viewer to the basics of syndromic surveillance and offers a high-level overview of the many uses of this public health tool. Topics covered in this training include:

Outbreak of ED visits related to the use of synthetic cannabinoids, Mayotte Island

On October 2016, the Indian Ocean Regional Health Agency was alerted about an increase in ED visits related to adverse reactions associated with use of SC on Mayotte Island. In this context, an investigation based on a syndromic surveillance system was implemented by the regional unit of the French national public health agency.

Objective:

To confirm and to characterize the increase in emergency department (ED) visits related to the use of synthetic cannabinoids (SC).

Tracking suspected heroin overdoses in CDC's National Syndromic Surveillance Program

Overdose deaths involving opioids (i.e., opioid pain relievers and illicit opioids such as heroin) accounted for at least 63% (N = 33,091) of overdose deaths in 2015. Overdose deaths related to illicit opioids, heroin and illicitly-manufactured fentanyl, have rapidly increased since 2010. For instance, heroin overdose deaths quadrupled from 3,036 in 2010 to 12,989 in 2015. Unfortunately, timely response to emerging trends is inhibited by time lags for national data on both overdose mortality via vital statistics (8-12 months) and morbidity via hospital discharge data (over 2 years).

Tracking drug-related overdoses at the local level: Using Syndromic Surveillance in the CO-NCR

The United States is in the midst of a drug crisis; drug-related overdoses are the leading cause of unintentional death in the country. In Colorado the rate of fatal drug overdose increased 68% from 2002-2014 (9.7 deaths per 100,000 to 16.3 per 100,000, respectively), and non-fatal overdose also increased during this time period (23% increase in emergency department visits since 2011).

Surveillance for Mass Gatherings: NCAA Final Four 2017 in Maricopa County, Arizona

Final Four-associated events culminated in four days of intense activity from March 31st through April 3rd, and added an estimated 400,000 visitors to Maricopa County's 4.2 million residents.

Objective:

To describe and present results for the enhanced epidemiologic surveillance system established during the 2017 National Collegiate Athletic Association Division I Men’s College Basketball Championship (Final Four) events.

Comparison of statistical algorithms for syndromic surveillance aberration detection

Syndromic surveillance involves monitoring big health datasets to provide early warning of threats to public health. Public health authorities use statistical detection algorithms to interrogate these datasets for aberrations that are indicative of emerging threats. The algorithm currently in use at Public Health England (PHE) for syndromic surveillance is the ‘rising activity, multi-level mixed effects, indicator emphasis’ (RAMMIE) method (Morbey et al, 2015), which fits a mixed model to counts of syndromes on a daily basis.

Evaluation of Syndrome Algorithms for Detecting Pneumonia Emergency Department Visits

The NYC Department of Health and Mental Hygiene (DOHMH) uses ED syndromic surveillance to monitor near real-time trends in pneumonia visits. The original pneumonia algorithm was developed based on ED chief complaints, and more recently was modified following a legionella outbreak in NYC. In 2016, syndromic data was matched to New York State all payer database (SPARCS) for 2010 through 2015. We leveraged this matched dataset to validate ED visits identified by our pneumonia algorithm and suggest improvements.

Syndromic Surveillance – Reports of Successes from the Field

Syndromic surveillance uses near-real-time emergency department and other health care data for enhancing public health situational awareness and informing public health activities. In recent years, continued progress has been made in developing and strengthening syndromic surveillance activities.

Updating syndromic surveillance baselines following public health interventions

Public Health England's syndromic surveillance service monitor presentations for gastrointestinal illness to detect increases in health care seeking behaviour driven by infectious gastrointestinal disease. We use regression models to create baselines for expected activity and then identify any periods of signficant increases. The introduction of a rotavirus vaccine in England during July 2013 (Bawa, Z. et al. 2015) led to a reduction in incidence of the disease, requiring a readjustment of baselines.

How do we present messy syndromic surveillance data to public health’s partners?

With increasing awareness of SyS systems, there has been a concurrent increase in demand for data from these systems – both from researchers and from the media. The opioid epidemic occurring in the United States has forced the SyS community to determine the best way to present these data in a way that makes sense while acknowledging the incompleteness and variability in how the data are collected at the hospital level and queried at the user level.
