Comparative Evaluation of Risk Scores for Predicting Postoperative Pulmonary Complications

In critically ill Chinese surgical subjects, the LAS VEGAS, ARISCAT, and CHI-BPRI scores had limited predictive performance for PPCs, and none of the scores achieved strong discriminative power. Among these, the LAS VEGAS score performed best and may offer modest utility for early risk identification. These findings underscore the need for improved, population-specific prediction tools tailored to the unique risk profiles of critically ill surgical patients.
