The NCDR CathPCI Registry: A US National Perspective on Care and Outcomes for Percutaneous Coronary Intervention

Study Questions:

What are the goals and functions of the National Cardiovascular Data Registry (NCDR) CathPCI Registry?


No treatment interventions are mandated; participating centers receive routine quality-of-care and outcomes performance feedback reports and access to a quality dashboard for personalized performance reports. Patients undergoing cardiac catheterization and percutaneous coronary intervention (PCI) are retrospectively identified. No informed consent is required, as data are anonymized. From inception in 1998, more than 12 million records have been submitted from 1,577 participating US centers.


Approximately 250 fields encompassing patient demographics, medical history and risk factors, hospital presentation, initial cardiac status, procedural details, medications, laboratory values, and in-hospital outcomes are included. Linkages with outside sources of data have permitted longitudinal outcomes assessment in some cases. Center personnel enter the data into the registry, in some cases facilitated by software vendors. There are nonfinancial incentives for center participation. Data completeness is noteworthy, with most fields missing at rates <5%. A comprehensive data quality program is employed to enhance data validity. Main outcome measures include quality process metrics and in-hospital patient outcomes. Data are available for research by application to:


The authors concluded that the registry contributes to quality of care by providing data feedback on a wide range of performance metrics to participating centers, and by facilitating local and national quality improvement efforts.


The NCDR CathPCI Registry is a national program that collects data about coronary angiography and PCI procedures in the United States. While the primary role of the registry is to characterize the quality of care provided to patients undergoing angiography and PCI and to serve as a platform for quality improvement, states and payers have employed the CathPCI Registry as part of broad quality programs and by investigators for cutting-edge clinically oriented research. The roles of the registry are also expanding substantially, extending to postmarket device surveillance, education, multicenter interventional research, and international collaborative projects.
