National Electronic Disease Surveillance System (NEDSS)
The National Electronic Disease Surveillance System (NEDSS) facilitates electronically transferring public health surveillance data from the healthcare system to public health departments. It is a conduit for exchanging information that supports NEDSS. Today, when states and territories voluntarily submit notifiable disease surveillance data electronically to CDC, they use data standards and electronic disease information systems and resources supported in part by NEDSS. This ensures that state data shared with CDC are submitted quickly, securely and in an understandable form. NEDSS helps connect the healthcare system to public health departments and those health departments to CDC by:
- Providing leadership and resources to state and local health departments to adopt standards-based systems needed to support national disease surveillance strategy;
- Enabling health agencies to use information technology more effectively by developing patient-centered systems that helps health departments identify issues such as co-morbidities (multiple disease or conditions) that occur in the same individual over time;
- Defining the content (i.e., disease diagnosis, risk factor information, lab confirmation results, and patient demographics) of messages sent using the HL7 messaging standard;
- Implementing content standards that the healthcare industry currently uses (e.g., LOINC as the standard for transmitting laboratory test names and SNOMED as the standard for transmitting test results) for increased interoperability between states and the healthcare industry; and providing the NEDSS Base System (NBS), a CDC-developed information system, to help reporting jurisdictions manage reportable disease data and send notifiable diseases data to CDC using Public Health Information Network (PHIN) standards (CDC PHIN website).
Today, all 50 states and Washington, D.C., use a NEDSS-compatible system to send case notifications to Nationally Notifiable Disease Surveillance System (NNDSS). To be considered NEDSS compatible, states must have information systems meeting these requirements:
- Disease data entry directly through an Internet browser-based system, thereby creating a database accessible by health investigators and public health professionals,
- Electronic Laboratory Reporting (ELR) that enables labs to report cases to health departments,
- Integration of multiple health information databases into a single repository, and
- Electronic messaging capabilities, enabling states to share information efficiently with CDC and other health agencies.
