Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) System for Outcome Prediction in Elderly Patients Undergoing Major Vascular Surgery

摘要

OBJECTIVE: POSSUM system is widely used and validated for 30-day mortality and morbidity prediction. The aim of this study was to evaluate the performance of five POSSUM's equations (POSSUM, P-POSSUM, V-POSSUM, V-POSSUM physiology and V-POSSUM Cambridge) on predicting 30-day mortality and morbidity in elderly patients undergoing major elective vascular surgery.
