Does the IRIS score accurately predict postoperative mortality in patients undergoing general or trauma surgery?
Effect estimate: AUC 0.90
The IRIS score, incorporating age, acute admission, acute operation, and grade of surgery, provides a practical and accurate tool for predicting postoperative mortality in general and trauma surgery patients.
Liebman et al. (2009) conducted a cohort in General or trauma surgery (n=33,224). IRIS score was evaluated on Postoperative mortality (AUC 0.90). The IRIS score accurately predicted postoperative mortality after general or trauma surgery with an area under the ROC curve of 0.90.
