COMPARISON OF THE POSSUM, P‐POSSUM AND CR‐POSSUM SCORING SYSTEMS AS PREDICTORS OF POSTOPERATIVE MORTALITY IN PATIENTS UNDERGOING MAJOR COLORECTAL SURGERY

Abstract

Physiologic and operative severity score for the enumeration of mortality and morbidity, P-POSSUM and Cr-POSSUM are all reliable predictors of postoperative mortality in the Australasian context; although there was a trend towards POSSUM and P-POSSUM being better predictors than Cr-POSSUM. However, Cr-POSSUM requires fewer individual patient parameters to be calculated and is thus easier to generate. An ideal preoperative scoring system remains to be developed for predicting mortality in patients undergoing colorectal surgery.
