New York City developed the NYC Macroscope, a population health surveillance system that uses electronic health records (EHRs) to track conditions managed by primary care practices that are important to public health.
Using the NYC Macroscope, we are able to monitor in real-time the prevalence of chronic conditions, such as obesity, diabetes and hypertension, as well as smoking rates.
For more information, see our three published papers below, or email email@example.com.
The NYC Macroscope has been validated by comparing ambulatory EHR data with data from the 2013-14 NYC Health and Nutrition Examination Survey (NYC HANES 2013-14), a gold-standard, population-based health survey. The lessons learned in developing the NYC Macroscope will be useful to other agencies and researchers interested in using EHRs to monitor population health.
EHRs that have been constructed with population health management goals in mind can complement and expand the capacity of existing surveillance systems by capturing care events economically and with relative completeness.
Phase II (Completed June 2014):
Collected EHR data on priority health indicators:
Phase III (Completed December 2016):
Three papers describing the methods and findings of the NYC Macroscope were published in the December 2016 issue of the journal eGEMs.
The NYC Macroscope team is examining the accuracy of neighborhood-level estimates, as well as estimates stratified by race/ethnicity to explore how the NYC Macroscope can be used to monitor health inequities. We are also studying EHR-based trends from 2012 to 2016 and comparing them with trends from established surveys.
