Abstract
P-POSSUM is a simple scoring system, described and validated in developed countries like UK. A total of 150 emergency laparotomies were performed. The risk of complication and death was calculated using P-POSSUM equations. The estimated rates were compared with observed rates using both linear and exponential methods of analysis. P- POSSUM of the linear method predicted accurate number of deaths (19 patients) with O:E ratio of 1. When exponential method used it predicted similar number of deaths (20 patients) with O:E ratio of 0.95 with no significant difference.
