What is Cypress?

Cypress is the rigorous and repeatable testing tool of Electronic Health Records (EHRs) and EHR modules in calculating Meaningful Use (MU) Stage 2 Clinical Quality Measures (CQMs). The Cypress tool is open source and freely available for use or adoption by the health IT community including EHR vendors and Authorized Testing Labs. Cypress serves as the official testing tool for the 2014 EHR Certification program supported by the Office of the National Coordinator for Health IT (ONC).

Certification of EHR technologies under the ONC certification program requires that EHR software products and EHR modules be tested, as applicable, for their capabilities to capture, calculate, and report accurately the CQM results. To support this, ONC has commissioned the development of the open source Cypress certification tool. Cypress has encoded the Eligible Professional (EP) and Eligible Hospital (EH) Clinical Quality Measure logic required for Meaningful Use Stage 2 in a software implementation.

CQM certification

CQM certification criteria addressed by Cypress includes:

  • Record and Export - Record clinical data and export it in a format usable by other EHRs
  • Import and Calculate - Import data from other EHRs and perform CQM calculations
  • Report - Create standard data files that can be electronically submitted to quality reporting programs
  • Data Filter - Filter clinical data based on patient and provider data

Cypress Test Data

The Cypress software includes a standard test data of synthetic patient records that exercises all of the MU Stage 2 CQMs, for Eligible Professionals (EP) and Eligible Hospitals (EH) to test the ability for EHR systems and EHR modules to accurately calculate and report CQM results. The Cypress test data is available in QRDA Category I format for input into an EHR system.
