Smoking status and 30-day mortality in patients undergoing pulmonary resections

Conclusions Current smokers and ex-smokers are statistically different with regard to risk factors for death. This results in a skewed population of current and ex-smokers undergoing resection for non-small-cell lung cancer. Development of a risk model for 30-day mortality revealed that current smokers have a lower predicted 30-day mortality than ex-smokers, a finding that is counterintuitive. Propensity matching balanced the current and ex-smoker groups to correct for group differences. Analysis after propensity matching identified current smoking as a significant factor determining 30-day mortality.
