This registry study which links Society of Thoracic Surgeons (STS) data with Medicare data examined the rates and predictors of readmission within 30-days of coronary artery surgery. The median readmission rate across 846 hospitals was 16.8%. Predictors of readmission within 30-days of surgery were dialysis, chronic lung disease, creatinine, insulin-dependent diabetes, obesity in women, female gender, immunosupression, pre-operative atrial fibrillation, age, recent MI and low body surface area in men. The c-index for the developed model was 0.648 with 6.1% of hospitals having statistcially worse or better readmission rates than expected.
