Abstract

Background Predict Morbidity and Mortality rate postoperation is the essential part of all surgical because both Morbidity and also Mortality is an important outcomes and objectively. Possum as a tool for surgical audit and predictor for morbidity and mortality rate can allow a meaningful analisis based on the severity of illness. ln this study, validity of Possum was applied in patients undergoing laparotomi.

Methods 71 patients who underwent emergency laparatomy in an emergency unit were studied prospectively. Predicted morbidity and mortality rate were calculated by Possum using linear analysis. Those were compared with actual outcomes.

Result Both the correlation between Possum with Mortality show a valued positive correlation that can prove with significantion 0,000 (p=0,000) with strong 0,683 (r : 0,683) and also the correlation between Possum with Morbidity show a valued positive correlation that can prove with significantion 0,000 (p = 0,000) with strong 0,519 (r : 0,519).

Conclusions Possum were good predictors for morbidity and mortality in patients undergoing laparatomi that can used as a tool for surgical audit in patients undergoing laparotomi emergency.
