Coronary Artery Bypass Graft Surgery

Hospital 30-day, all cause, unplanned, risk-standardized readmission rate following CABG surgery

The measure estimates a hospital-level risk-standardized readmission rate, defined as unplanned readmission for any cause within 30 days from the date of discharge of the index CABG procedure, for patients 18 years and older discharged from the hospital after undergoing a qualifying isolated CABG procedure. The measure was developed using Medicare FFS patients 65 years and older and was tested in all-payer patients 18 years and older. An index admission is the hospitalization for a qualifying isolated CABG procedure considered for the readmission outcome.
