As New York City’s first electronic health record (EHR) surveillance system, NYC Macroscope complements traditional methods of monitoring the health of a population, such as statistically representative telephone and in-person surveys. While traditional methods are scientifically rigorous and have enduring important qualities, they are also labor intensive and can take a long time to yield results. 

In contrast, EHRs are electronic versions of a patient’s medical records maintained by health care providers at patient visits. Data within these records can be more easily available and summarized in a timely manner.

The authors compared 2013 results from NYC Macroscope to two different traditional surveys: the 2013-14 NYC Health and Nutrition Examination Survey (NYC HANES) and the 2013 Community Health Survey. They found that NYC Macroscope prevalence estimates for obesity, hypertension, smoking, and diabetes were comparable to the survey results. However, the treatment and control measures for diabetes, hypertension and high cholesterol were not.

Despite that variation, findings confirm that a carefully constructed EHR-based surveillance system can generate prevalence estimates comparable to those from gold-standard examination surveys for certain conditions and risk factors.

NYC Macroscope and NYC HANES were initiatives designed and implemented by a team of researchers at the NYC Department of Health and Mental Hygiene, in partnership with researchers at the CUNY School of Public Health (who are now at the NYU School of Medicine).
