• Real-world populations (that is, not in the context of a clinical trial).

  • A population denominator.

  • Followup for adverse events.

The mission of the NCDR is “to improve the quality of cardiovascular patient care by providing information, knowledge, and tools; implementing quality initiatives; and supporting research that improves patient care and outcomes.” Although the NCDR was not set up primarily for postmarket surveillance, Masoudi said, it is one of its benefits. The NCDR is actually a suite of cardiovascular-disease registries (see Box 3-1). Several of the NCDR registry programs are focused on procedures and devices, Masoudi noted.

The data-collection platform is similar in all the NCDR registries, using electronic data collection to capture a wide array of detailed demographic and clinical characteristics for each patient, details of procedures that are performed, and inhospital complications. The data include detailed information on the devices used for each procedure.

Each institution that submits data to the NCDR receives quality benchmark reports that can be used to support self-assessment and quality improvement by the institution.
