Operative Risk Score For The General Surgery (ORSGS)

Objective To establish a scoring system for predicting the occurrence of postoperative complications and mortality after general surgery, and evaluate the accuracy of it. Methods Eighty-four cases with postoperative complications or death and 172 postoperative cases without complications, treated in the last two years, were retrospectively analyzed by means of Logistic regression . Age, cardiovascular system, respiratory system, blood system, endocrine system, central nervous system, liver function, renal function, nutritional condition and operational wound, anesthesia condition, 15 indexes were investigated. We explored the main risk factors, and established the scoring system. Using independent-samples T test to evaluate the scoring system. Compared the ROC curves of APACHE II, POSSUM and operative risk score. Result The high-risk factors such as age, cardiovascular system, respiratory system, liver function, renal function, blood system, endocrine system, nutritional condition, the time of operation, amount of bleeding, anesthesia condition were all added to the scoring system. The scores between groups of postoperative complications and noncomplications, groups of the death and the survival, groups of the death and the survival with complications had significant difference. Compared ORSGS with APACHE II and POSSUM , they had significant correlation-ship. The ROC curves show they all can forecast the postoperative complications and mortality well. Conclution ORSGS had well correlated characteristic with postoperative complication and mortality. It can predict postoperative complications and mortality accurately as well as POSSUM and APACHE II. Compared with them, ORSGS had better efficacy by preliminary observation.
