Cypress

Cypress is an open-source testing platform that health information technology (IT) vendors use to certify their electronic health records (EHRs) and certified health IT modules (CEHRT) for electronic clinical quality measure (eCQM) calculations. It is an official testing tool within the Office of the National Coordinator (ONC) for Health IT Certification Program. As part of certification, Cypress generates synthetic patient data for selected published eCQMs and evaluates whether EHR systems and health IT modules can correctly capture, import, calculate, filter, and report those measures.

Cypress Validation Utility + Calculation Check (CVU+) enables real-world testing by allowing organizations to run tests using their own patient data. It supports validation against CMS Quality Reporting Document Architecture (QRDA) Implementation Guides (IGs) and performs eCQM calculations with highlighted measure logic.
