popHealth is an open source tool that allows healthcare providers to calculate quality measures. A quality measure is a calculation of the number of individuals in a population that meet a specific standard of care. The goal of this project is to build a reference implementation of the quality measures providers need to report to Centers for Medicare and Medicaid Services (CMS) in order to meet the requirements of Meaningful Use.

This project is sponsored by the Office of the National Coordinator for Health Information Technology (ONC) to streamline the reporting of quality measures. popHealth is a web application that integrates with electronic health record systems (EHR) by collecting patient summary documents in either ASTM CCR or HITSP C32 formats. Providers can then view how their patient populations are performing against defined standards of care using only a web browser.

This talk will cover the following:

  • Explanation of a quality measures with a walkthrough of a concrete example
  • A brief overview of the ASTM CCR and HITSP C32
  • Overview of how popHealth stores patient population information in MongoDB. We will show how we use MongoDB’s built in MapReduce functionality to calculate quality measures.
  • Discuss how popHealth can integrate with existing health IT systems as a standalone web application or by building upon the Quality Measure Engine Ruby gem.
