Benuzillo et al reported a model for predicting the risk of 30-day readmission for a patient admitted for CABG surgery. The authors are from Intermountain Healthcare in Salt Lake City.
Patient selection: coronary artery bypass graft surgery (CABG)
Outcome: 30-day readmission rate
Parameters:
(1) age in years
(2) serum albumin in g/dL prior to surgery
(3) history of prior heart failure
(4) history of diabetes
(5) history of previous myocardial infarction

probability of 30-day readmission =
= 1 / (1 + EXP((-1) * X
Performance:
• The area under the ROC curve is 0.63 in the derivation and 0.65 in the validation cohorts.
