What is the CathPCI Registry™ The premier national, voluntary cardiovascular data registry that provides institutions with the ability to understand, measure, and improve quality of cardiovascular care. A comprehensive measurement system linked to ACC clinical practice guidelines and performance measures that rely on a set of nationally recognized standardized data elements and definitions. Current module focuses on the quality of care in the cardiac catheterization laboratory with anticipation of expansion into other clinical areas in the very near future. At this time, over 600 sites enrolled in the registry nationwide, with increasing national representation due to growing consumer, payer and regulator demand for quality in the cath lab. Multi-phased audit program in place to ensure highest integrity of data captured; national on-site data auditing program launched January 2004. Over 2 million patient records, including over 800,000 PCI procedures representing 6 years of data. PCI mortality rate is risk adjusted. Each year the National Quality Forum and the Leapfrog Group have adopted the CathPCI Registry™ PCI risk adjusted mortality rate measure as a standard of quality in lieu of procedure volume requirements.
