Abstract
BACKGROUND: <0.05). The readmission rates among the 119 hospitals performing CABG varied from 0% to 26.9%. Compared with hospitals in lower quartiles for readmission, hospitals in higher quartiles had a significantly higher readmission rates due to circulatory diseases, infections, complications for surgical and medical care and digestive diseases (all P<0.05). In a hierarchical model, including several hospital characteristics, hospital-level variables did not predict readmission risk (all P>0.05, with an intraclass correlation of 0.004 for hospitals).Conclusions-California hospitals performing CABG surgery vary widely in 30-day readmission rates. Patient demographic and clinical risk factors, rather than measured hospital characteristics, accounted for most of the observed hospital-level variation in CABG readmissions.
