May support simpler morbidity risk adjustment in surgical audit; leaves open external validation before clinical adoption.
Observational
Effect estimate: AUC 0.86
A newly developed 12-variable risk adjustment model for general surgical audit demonstrated high predictive power (AUC 0.86) for postoperative morbidity.
Pillai et al. (1999) conducted an observational in General surgical patients. Risk adjustment model was evaluated on Severe and intermediate complications (postoperative morbidity) (AUC 0.86). A 12-variable risk adjustment model for general surgical audit predicted postoperative morbidity with an area under the receiver operating characteristic curve of 0.86.
