Patient selection: CABG
Outcomes: sternal infection and 4-year survival
Predictors for superficial sternal wound infection:
(1) BMI >= 30 kg per square meter (odds ratio 2.0)
(2) NYHA class 3 or 4 (odds ratio 1.6)
(3) use of bilateral internal mammary arteries (odds ratio 3.8)
(4) increasing number of coronary artery grafts (odds ratio 1.6 per graft)
(5) re-exploration for bleeding (odds ratio 3.7)
Predictors for deep sternal wound infection:
(1) increased duration of mechanical ventilation (odds ratio 1.04 for every 10 hours)
(2) insulin-dependent diabetes mellitus (odds ratio 5.0)
(3) peripheral vascular disease (odds ratio 3.7)
Predictors for any sternal wound infection by logistic regression model:
(1) BMI >= 30 kg per square meter (odds ratio 2.0)
(2) NYHA class 3 or 4 (odds ratio 1.6)
(3) use of bilateral internal mammary arteries (odds ratio 3.2)
(4) increasing number of coronary artery grafts (odds ratio 1.5 per graft)
(5) re-exploration for bleeding (odds ratio 3.1)
(6) increased duration of mechanical ventilation (odds ratio 1.12 for every 10 hours)
