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.
