Data Quality Assurance






Hospitals participating in the HQA initiative provide their data to the QIO Clinical Data Warehouse. The Quality Improvement Organizations' (QIO) Clinical Data Warehouse stores provider-reported performance measure data for quality improvement and public reporting. It is the intent of CMS that the QIO Clinical Data Warehouse will ultimately provide four (4) quarters of data, updated quarterly, for each participating hospital.


The CMS Abstraction and Reporting Tool (CART) is a medical record data abstraction tool that builds on over 10 years of measurement activity. It currently generates both CMS/The Joint Commission aligned measures as well as the ten core CMS/The Joint Commission aligned measures, with full alignment slated for future development. Hospitals may use the CART to transmit abstracted data directly into the QIO Clinical Data Warehouse through www.QualityNet.org (a HIPAA-compliant, secure data transmission vehicle) or they may instruct a vendor to submit the data on their behalf using QNET. CART may also be used to transmit data directly to an ORYX vendor from a current Joint Commission-accredited hospital. The vendors transmit the data to the QIO Clinical Warehouse, if the hospital has authorized them to do so, on their behalf. Under The Joint Commission program, organizations that wish to be certified as ORYX vendors must pass certain tests that verify their capacity to correctly handle hospital data and calculate performance rates using the prescribed algorithms.


Both ORYX Vendors and CART data submissions include auditing procedures and edit checks, which assess whether data submitted is consistent with defined parameters for sample size, outliers, and missing data. In addition, CMS intends to validate data submitted to the Warehouse for the HQA initiative. The validation process will provide assurance that the hospital, or its designated agent, can accurately abstract patient medical records and accurately submit data to the QIO Clinical Data Warehouse. The data for this posting has been audited/edited, but not validated.
