What Are We Measuring?

Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease, a disease in which a substance called plaque builds up inside the coronary arteries.

The Centers for Medicare and Medicaid Services (CMS) evaluates 30-day mortality and readmission rates for patients who have CABG surgery:

  • 30 Day Mortality Rate: the percentage of CABG patients who died within 30 days of admission to the hospital
  • 30 Day Readmission Rate: the percentage of CABG patients who were discharged from the hospital and were readmitted to any hospital for any reason in the next 30 days
