Abstract


P-POSSUM score is a scoring system used in assessment of mortality in exclusively surgical patients. In this study we aimed to evaluate PPOSSUM
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; pvalue=
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.
