Test Data

The Cypress patient test data consists of:

  • 81 synthetic patients designed to interact with and provide measure steward approved, gold standard expected results for the 64 Clinical Quality Measures (CQMs) selected for Stage 2 of Meaningful Use for Eligible Professionals (EPs); and
  • 81 synthetic patients designed to interact with and provide measure developer approved, gold standard expected results for the 29 Clinical Quality Measures (CQMs) selected for Eligible Hospital (EH) and Critical Access Hospitals (CAH).

These standardized set of patient test data will be used as the primary evaluation mechanism for Electronic Health Record (EHR) vendor performance on clinical quality measure implementations via the Cypress software. It has not been designed to be an exhaustive test of all logical elements. Instead, the patient test data has been designed instead to provide a simplified and standardized representation of common population information for a CQM software implementation to process and accurately calculate results.

Clinical Quality Measure Testing Procedure

The Office of the National Coordinator continues to post updates to the 2014 Edition ONC-Approved Test Method for the ONC HIT Certification Program.

JIRA Bug Tracking System

JIRA is used by CMS and ONC to track issues or bugs associated with the electronic Clinical Quality Measures (eCQM). Access to the JIRA-Clinical Quality Measure Feedback System is available here. For assistance using the JIRA system, the JIRA-Clinical Quality Measure Feedback System Instructions are available.

Clinical Quality Measure Logic Document

An updated document detailing the Clinical Quality Measure Logic has been posted on the Center for Medicare and Medicaid Services website and is publicly available.


The Standards Implementation & Testing Environment is a centralized set of tools designed to assist the implementers of Health Information Technology standards required for certification of Electronic Health Record (EHR) technology, and in general, enable interoperable health information exchange. SITE is divided into sandboxes, one for each supported standard.
