CONCLUSION AND SUMMARY:
• APACHE II score is the current gold standard for assessing the severity of acute perforation peritonitis.
• The mortality rate in our study of 50 patients was found to be 18 %.
• An APACHE II score of 15 and above predicted mortality in our study population with a positive predictive value of 100%.
• The overall accuracy of this score was found to be 100%.
• APACHE II score is more physiological in emergency settings compared to Manheim’s score.
• Compared to the MPI score, APACHE II score could be used serially to monitor the patient in the immediate post operative period.
• Patient treatment can be optimized by appropriate intensive supportive care when it is determined to be needed.
• APACHE II score can triage the patients with the treatment directed to the most effective patient.
• Scoring patients into groups based on risk could help future clinical research by comparing therapeutic interventions in similar patients. Of the two scoring systems evaluated, the APACHE II seems to be better suited to achieve these goals
