Abstract :

P–POSSUM score is a scoring system used in assessment of mortality in exclusively surgical patients. In this study we aimed to evaluate P–POSSUM scoring in predicting in–patient mortality in elective and emergency surgeries separately. 300 patients undergoing any general surgical procedures were included in the study. Predicted mortality rates were calculated using P–POSSUM equation by linear analysis and compared with the raw mortality observed. On analysis O: E ratio of 1.05(χ²=0.006; 4 df; p–value=0.99) was obtained in elective cases and 1.08(χ²=0.02; 4 df; p–value=0.99) in emergency cases showing no statistical difference between the observed and P–POSSUM predicted mortality rates. There have been several attempts at creating a scoring system to predict mortality risk after surgery. Of the few available P–POSSUM appears to be the most appropriate and is claimed to produce a closer fit with the observed patient mortality rate.
