Establishment of a new scoring system for preoperative evaluation of operative risks in the elderly patients with hip fractures / 中华创伤杂志

ABSTRACT

Objective To develop a new scoring system,Daping orthopedics operation risk scoring system for senile patient(DORSSSP),for preoperative evaluation of operative risks in the elderly patients with hip fractures based on acute physiology and chronic health evaluation(APACHE)Ⅱ scoring system and physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM)and compare the new scoring system with APACHE Ⅱ and POSSUM in assessing surgical risks and predicting postoperative complications and mortalities.Methods A total of 260 patients with hip fractures treated in our department in recent five years were retrospectively and respectively evaluated with DORSSSP,POSSUM,progressed POSSUM(P-POSSUM)and APACHE Ⅱ scoring system to compare the value of three scoring systems in preoperative evaluation of operative risks and prediction of postoperative mortality and complications.Results POSSUM and DORSSSP predicted complications in 119 and 92 patients respectively,while the actual complication occurred in 84 patients.The prediction value of POSSUM was significantly higher than the actual value,while the prediction value of DORSSSP showed no statistical difference compared with the actual value.POSSUM,P-POSSUM and APACHEⅡ scoring systems predicted 16,10 and 12 deaths respectively,but there were six deaths in fact,with prediction value obviously higher than the actual value.DORSSSP predicted nine deaths,the closest value to the actual.Conclusions DORSSSP has good correlation with postoperative complications and mortalities.Compared with POSSUM and APACHE Ⅱ scoring system,more simple and practicable DORSSSP can more accurately evaluate the preoperative risks and predict the postoperative complications and mortalities in the elderly patients with hip fractures.
