Conclusions P-POSSUM was the most accurate model for predicting post-operative mortality after colorectal cancer surgery .
The original POSSUM model was accurate in predicting post-operative complications
Introduction The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity  ( POSSUM ) model and its Portsmouth ( P-POSSUM ) and colorectal ( CR-POSSUM ) modifications are used extensively to predict and audit post-operative mortality and morbidity .
This aim of this systematic review was to assess the predictive value of the POSSUM models in colorectal cancer surgery .
Risk‐adjusted surgical audit with the POSSUM scoring system in a developing country
The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity  ( POSSUM ) is an objective and appropriate scoring system for risk‐adjusted comparative general surgical audit . This score was devised in the UK and has been used widely , but application of POSSUM to centres outside the UK has been limited , especially in developing countries . This prospect i ve study vali date d its application in a surgical practice with a different population and level of re sources
