SEDRIC: System for Enteric Disease Response, Investigation, and Coordination

What to know

  • The System for Enteric Disease Response, Investigation, and Coordination (also known as SEDRIC) is a secure, cloud-based platform for foodborne and animal contact outbreak investigations.
  • SEDRIC helps streamline and coordinate outbreak investigations by combining epidemiologic, laboratory, and traceback data in real time.
  • CDC partners have access to SEDRIC for free.

Overview

Responding to multistate outbreaks requires close collaboration, communication, and data sharing among local, state, and federal health and regulatory officials. SEDRIC helps streamline and coordinate outbreak investigations by combining epidemiologic, laboratory, and traceback data in real time. This allows investigators across the U.S. to collaborate effectively and solve outbreaks quickly.

SEDRIC provides a model for data integration systems for other groups at CDC involved in outbreak response.

What it is

SEDRIC is web-based software system (in the cloud) developed by CDC and Palantir Technologies. It facilitates collaborative multistate outbreak investigations of enteric disease.

SEDRIC has four major capabilities:

  1. Integrate multiple surveillance data sources in real time
  2. Visualize outbreak data rapidly in one place
  3. Provide a secure platform for partner collaboration
  4. Manage a repository of historic surveillance and outbreak data

Who it's for

CDC's partners who investigate foodborne and animal-related disease outbreaks have free access to SEDRIC. More than 450 people are using SEDRIC, with users in all 50 states and Puerto Rico.

CDC partners using SEDRIC include:

  • State and local health departments
  • U.S. Department of Agriculture Food Safety and Inspection Service
  • U.S. Food and Drug Administration

How SEDRIC works

SEDRIC ingests surveillance data from PulseNet, NARMS, NORS, OMS, EDMI, and Epi Info as well as investigation data from epidemiologists, environmental health, regulatory agencies from state, federal partners. SEDRIC then compiles this information for data exploration, secure sharing, and visualization.

SEDRIC provides tools that integrate multiple data streams.

Line Lists

Create and edit lists of information about each ill person in an outbreak, including relevant demographic, clinical, laboratory, and exposure data.

Maps

Visualize the geographic spread of illnesses, including capabilities to view illness distribution over time.

Outbreak Dashboards

View summary data for outbreaks, including demographics, when illnesses occurred, and laboratory data

Traceback Diagrams

Construct complex diagrams to connect illnesses to a common point of contamination.

Spotlight

During the third largest Salmonella outbreak in CDC PulseNet history, SEDRIC successfully managed a line list of hundreds of cases that grew exponentially every day as new infections were reported. As state health officials identified new cases and interviewed them, they were able to add exposures to the SEDRIC line list in real-time, allowing CDC to detect the signal for cucumbers early on in the investigation.
