Assessment of morbidity and mortality by P-POSSUM scores in Emergency GI Surgeries

Background: Assessment of morbidity and mortality risk inemergency gastrointestinal surgeries is a fairly difficultchallenge. To have a better scientific, reliable, and reproduciblemethod of assessment POSSUM and its modified version PPOSSUM scores have been devised. In this study, we tried toevaluate the P-POSSUM Scores in patients undergoingemergency GI surgical procedures.Methods: This study was done in the Department of GeneralSurgery, PIMS a tertiary care hospital. Consecutive emergencysurgical procedures following inclusion and exclusion criteriawere selected for the study. A total of n=50 cases were includedin the study. P-POSSUM scores were derived for each of thecases and analysis of the predicted morbidity and mortalitywas compared.Results: The range of 9.9% risk was done to categorize into 10different groups with increasing order of scores. The highestfrequency was observed in 20.1 – 30.0% which was 22% lowerfrequency scores were observed in higher extremes. Themorbidity risk scores show the highest frequency in 32% inthe range of > 90.0 cases followed by 80.1 – 90.0 having casesof 28%.Conclusion: P-POSSUM is an accurate and reliable scoringmethod for assessing morbidity and mortality in emergencyGastrointestinal surgeries. However, it was found tooverestimate mortality and morbidity in our patientpopulation. P-POSSUM over-estimates risk for morbidity in lowrisk groups w
