MENDS Project Making Progress in Using EHR Data for Near Real-Time Chronic Disease Surveillance

March 2021

There is now active data exchange in MENDS (Multi-state EHR-based Network for Disease Surveillance), putting the project a step closer to using EHR data for near real-time chronic disease surveillance.

MENDS is a demonstration project funded by CDC’s Division for Heart Disease and Stroke Prevention that uses EHR data for chronic disease surveillance. This new phase of work is live with our Washington State Department of Health partner site, and a second partner site close behind (REACHnet).

The above two partner sites, in collaboration with NACDD and our technical partner, Commonwealth Informatics, are working through the validation stages to confirm a uniformly high level of data quality across partner sites.

Initial data from these partner sites is also being used to refine the procedures and processes for the weighting and modeling work being conducted by the University of Massachusetts. This is work is being done to ensure estimates accurately reflect the underlying populations, as well as to produce model-based estimates for geographic regions and populations that are underrepresented in MENDS.

The entire MENDS network continues to finalize its governance by establishing the structure and processes that will guide the work, cumulating in an all-inclusive governance document that speaks to the principles, polices, and processes of MENDS.
