What is it? The Centers for Disease Control and Prevention (CDC)
vision is to remove the stovepipes from existing public health information systems and replace them
with an interoperable and scaleable information management infrastructure.
At the core of that vision is the National Electronic Disease Surveillance
System (NEDSS), an integrated application architecture designed to manage
the capture, dissemination, and reporting of notifiable disease data in an
efficient and timely manner. NEDSS employs standardized code sets for tracking and
analysis, as well as provides support for secure messaging among the various Independent, Local,
State and Federal institutions that use health data. This includes
health care providers, laboratories, public health departments, and other syndromic
surveillance data sources.
The Public Health Information Network (PHIN) expands upon the NEDSS approach
of standards-based systems integration and applies it to other business
processes and functions of the public health information life-cycle.
PHIN will enable automated and real-time data flow, computer assisted
analysis, program area decision support, professional collaboration,
and rapid dissemination of information to public health organizations, the clinical
care community, and the public through a common integrated and
standards-based framework for public health systems and operations.
What's the Intent? The principal intent of NEDSS is to decrease the
amount of associated reporting time and increase the accuracy and relevancy of the
public health data for detecting and responding to disease-related incidents
or situations that threaten the health and safety of the nation's citizenry.
By integrating data sources, the NEDSS architecture will provide a tool for
improved decision making. Consequently, NEDSS is a prime component within
the PHIN architectural model.
Implementation of the PHIN architecture will further improve the ability of
the public health community to readily access clinical
data for analysis in a seamless fashion, develop linkages that support the continuous detection
and evaluation of threats across jurisdictions, and achieve enhanced
information flow to the public and decision support to public health
professionals.
Functional Guidelines for PHIN/NEDSS Components:
Support Web browser-based data entry and data management
Accept, route and process electronic HL7 messages
Implement an integrated data repository [Public Health CDM/ HL7 RIM]
Develop active data translation and exchange functionality
