American College of Cardiology percutaneous coronary intervention (PCI) readmission measure

The PCI readmission measure shows how often Medicare fee-for-service (FFS) patients are readmitted to a hospital after a PCI procedure. The measure uses data from the Centers for Medicare & Medicaid Services (CMS) and the National Cardiovascular Data Registry® (NCDR) CathPCI Registry®Exit Disclaimer - Opens in a new window.     Hospitals participating in the registry may elect to voluntarily report their measure results through a collaborative effort between CMS and the American College of Cardiology.

Results are displayed in the data table below.

Why these measures are important

Readmissions are costly to the healthcare system and are burdensome to patients and their caregivers. Not all readmissions are unplanned, but measuring and reporting unplanned readmission rates across hospitals can reveal opportunities for improvement. Hospitals may be able to lower readmission rates by improving patient care and planning for patients’ needs once they leave the hospital.

PCI is one of the most common cardiac procedures in the United States. In appropriate patients, PCI can improve quality of life, increase exercise capacity, and reduce symptoms of angina. Furthermore, among heart attack patients, PCI may improve survival.

One out of seven patients that undergoes a PCI procedure is readmitted within 30 days according to a studyExit Disclaimer - Opens in a new window     published in the Journal of the American College of Cardiology. Unplanned readmissions after a PCI may reflect the quality of care that hospitals provide to patients before, during, and after the procedure. For example, patients may need to be readmitted to the hospital for complications of the care they received during their hospital stay, insufficient discharge planning at the end of their hospital stay, or a worsening of their condition after they leave the hospital.

Measure details

The PCI readmission measure compares hospitals based on unplanned readmissions that occur within 30 days of discharge following a PCI procedure. These comparisons take into account how sick patients were before they were admitted to the hospital and differences in readmission rates that might be due to chance. For example, patients who are older and have other medical problems are more likely to be readmitted than younger, healthier patients. The measure accounts for these differences through risk adjustment and produces a risk-standardized readmission rate (RSRR) for each hospital.

Each eligible hospital is assigned to one of three categories:

  • Better than CathPCI Registry® rate
  • No different than CathPCI Registry® rate
  • Worse than CathPCI Registry® rate

Hospitals with fewer than 25 PCI cases are categorized as “number of cases too small” because these hospitals do not provide enough information to reliably estimate their performance.

These categories reflect each hospital’s performance compared to the overall NCDR® CathPCI Registry® unplanned readmission rate of 11.9%. The measure uses the RSRR and the 95% interval estimate (CI) for each hospital to categorize the hospital’s performance. The interval estimate represents the range of probable values for the rate.

How to find your hospital’s results

The table below displays measure results for NCDR® CathPCI Registry® hospitals that are participating in voluntary public reporting. Performance results are not available for NCDR® CathPCI Registry® hospitals participating in voluntary public reporting that did not have sufficient numbers of PCI cases between 2010 and 2011.

To help you find the information that is most relevant to you, you can sort this table by hospital name, state, performance category, and RSRR.

Data Reporting Period: January 1, 2010 – November 30, 2011
