Brief Summary
Although several clinical predictive models have been developed to predict postoperative pulmonary complications, few predictive models have been developed for elderly patients. In this study, the researchers aimed to develop a new, simplified model to assess the risk of postoperative pulmonary complications in elderly patients using perioperative database information.
