A newly developed 7-variable clinical scoring system demonstrated good discriminative ability for predicting postoperative pulmonary complications in patients undergoing non-cardiothoracic surgery.
Effect estimate: AUC 0.79 (95% CI 0.75-0.83)
Patient- and procedure-related factors associated with postoperative pulmonary complications (PPCs) have changed over the last decade. Therefore, we sought to identify independent risk factors of PPCs and to develop a clinically applicable scoring system. We retrospectively analyzed clinical data from 2,059 patients who received preoperative evaluations from respiratory physicians between June 2011 and October 2012. A new scoring system for estimating PPCs was developed using beta coefficients of the final multiple regression models. Of the 2,059 patients studied, 140 (6.8%) had PPCs. A multiple logistic regression model revealed seven independent risk factors (with scores in parentheses): age ≥70 years (2 points), current smoker (1 point), the presence of airflow limitation (1 point), American Society of Anesthesiologists class ≥2 (1 point), serum albumin <4 g/dL (1 point), emergency surgery (2 points), and non-laparoscopic abdominal/cardiac/aortic aneurysm repair surgery (4 points). The area under the curve was 0.79 (95% CI, 0.75-0.83) with the newly developed model. The new risk stratification including laparoscopic surgery has a good discriminative ability for estimating PPCs in our study cohort. Further research is needed to validate this new prediction rule.
Jeong et al. (2014) conducted an observational in Postoperative pulmonary complications (PPCs) risk (n=2,059). 7-factor predictive scoring system was evaluated on Discriminative ability (AUC) of the new predictive scoring system for estimating postoperative pulmonary complications (AUC 0.79, 95% CI 0.75-0.83). A newly developed 7-factor scoring system demonstrated good discriminative ability for predicting postoperative pulmonary complications, with an area under the curve of 0.79.
