DERSS GOAL
Provide users with the ability to enter, manage, and view information in support of disease reporting, syndromic surveillance and event management

• Early identification of event
• Ongoing assessment of risk
• Case and contact management
• Implement disease control measures
• Provide medical management and infection control guidance
• Environmental health assessment
• Carry out Public Health and Medical Plan (ESF-8)
Public Health Role in Emergency Response: Terrorism

Identifying an “Event” The Perfect Surveillance System
• Real time
• 100% complete reporting
• Surveillance for symptoms and diagnosed illnesses (e.g. anthrax)
• Reporting by non-traditional sources
• Easy for health care providers
• Rapid analysis of incoming data

• Automates as much of the current system as possible • Uses national standards (CDC’s National Electronic
Disease Surveillance System)• More accurate data, faster• Syndromic surveillance and 65 “diagnosed” diseases• Enhanced tools for data analysis• Automatically flags and notifies when aberrations• HIPAA compliant and secure• Expandable: backbone for other applications

DERSS Data Sources
• First phase: hospitals and laboratory
• Then: pharmacies, smaller providers, other non-traditional sources
• Secure WEB Portal for entry of individual reports if economy of scale too small for automated scanning of databases
• Paper reports will continue for partners without WEB

DERSS Analysis
• Automated data checking and elimination of duplicate information
• Integration of health information from multiple sources
• Extensive analytic tools for event detection and epidemiologic decision-making
• Mapping and GIS• Automated notification of aberrations • Incident management

Timeline
• Hospitals participated in pre-development assessment (July 2002)
• Contract awarded August 2003 to Northrop Grumman
• Interface with hospitals, laboratories to begin in March, 2004
• Base system expected to be completed by Oct 2004• System capable of expansion (additional data
sources) thereafter
