Assessment of SORT value in predicting complications after a major surgery
Main Article Content
Abstract
As more than 300 million surgeries are performed wordwide yearly, it is necessary to accurately atratify patients’s risk. The object of this study was to assess the performance of SORT in Vietnamese patients undergoing major surgery. We conducted a descriptive prospective study on 243 patients who underwent major surgery in Hanoi Medical University Hospital. Hosmer-Lemeshow test was used to assess calibration. Area under curve ROC was used to assess discrimination. Observed mortality was 5.3%. Mortality predicted by SORT was 12.9%. Calibration at the Hosmer-Lemeshow statistic was not good with p < 0.01. The AUC for SORT was 0.869. The SORT was predictive of infection (AUC 0.7274), pneumonia (AUC 0.7809), respiratory failure (AUC 0.8216), ARDS (AUC 0.8012), postoperative bleeding (AUC 0.7266), acute kidney injury (AUC 0.8753). This result shows that the SORT demonstrated good discrimination in predicting mortality, however mortality was over- predicted after major surgery.
