PCI Readmission Measure

Hospital 30-Day Risk-Standardized Readmission Rate Following Percutaneous Coronary Intervention Measure

The ACC in collaboration with the Yale New Haven Health Services Corporation/Center for Outcomes Research and Evaluation (YNHHSC/CORE) and the Centers for Medicare and Medicaid Services (CMS) completed a pilot program in 2013 which reported a percutaneous coronary intervention (PCI) readmission measure to all NCDR CathPCI Registry hospitals. For institutions that further chose to participate in the public reporting option of the program, measure results were voluntarily publicly reported on CMS’s Hospital Compare website. The final update to the Hospital Compare website was completed in December 2013 and the pilot program is now closed.

About the PCI Readmission Measure

The measure that was reported assesses whether hospitals’ PCI readmission rates are better than, worse than, or on par with the CathPCI Registry unadjusted readmission rate. The measure, which was developed through collaboration among the ACC, YNHHSC/CORE and CMS, uses clinical data from the CathPCI Registry for risk adjustment and Medicare claims data to determine readmission outcomes. The National Quality Forum endorsed the measure in 2011.

The measure includes Medicare Fee-for-Service beneficiaries at least 65 years of age who receive a PCI at the hospital (as inpatients or outpatients) and were discharged between Jan. 1, 2010 and Nov. 30, 2011 (measurement period). For each hospital, the measure estimates hospital risk-standardized 30-day readmission rates based on unplanned readmissions to any acute care hospital within 30 days of discharge. CathPCI Registry hospitals must have submitted at least one eligible PCI procedure during the measurement period to be included in the measure. For more information about measure specifications please refer to the technical report in the Resources section below.

Voluntary Hospital Public Reporting of PCI Readmission Measure

With CMS funding and logistical support, the ACC afforded hospitals the opportunity to voluntarily publicly report their measure results. Hospitals that chose to participate in voluntary hospital public reporting had their results displayed on Hospital Compare.

Private Preview Period

Prior to choosing to participate in the public reporting option, CathPCI Registry hospitals had the opportunity to privately preview their hospital-specific reports by logging into their NCDR report dashboard. Hospitals with at least one case during the measurement period received their measure results in a Hospital-Specific Data and Results Excel file containing their detailed measure results, hospital stay-level data on readmissions, and hospital case-mix. As of April 2014 this report is no longer available for download.

Informational Webinar

The ACC hosted a live webinar for hospitals to learn more about the measure and voluntary public reporting. For a detailed review of the webinar material please access the archived webinar slide deck. You can also find more information about the measure and voluntary public reporting in the frequently asked questions document in the Resources section below.

How to Participate in Voluntary Hospital Public Reporting

The PCI 30 day readmission measure pilot ended in December 2013 when the Hospital Compare display was updated with the final list of CathPCI Registry hospitals which participated in the pilot. The ACC is now in process of implementing a larger public reporting program containing multiple measures and multiple NCDR registries.  You are encouraged to learn more about the full program and to take advantage of this continuing quality reporting opportunity by accessing the new public reporting program website.
