建立一种新评分系统用于术前评估老年髋部骨折手术风险

目的 参照急性生理学和慢性健康状况评分系统(acute physiology and chronic health evaluation,APACHE)Ⅱ评分系统、生理学和手术严重度评分系统(physical and operation severity score for the enumeration of mortality and morbidity,POSSUM)建立适合我国骨科老年患者的手术风险评估系统,即大坪骨科老年患者手术风险评分系统(Daping orthopedics operation risk scoring system for senile patient,DORSSSP),将其应用于临床并与APACHE Ⅱ和POSSUM进行比较,以期达到评估术前手术风险及预测术后并发症和死亡的发生概率.方法 建立DORSSSP评分系统,分别应用DORSSSP、POSSUM、改良POSSUM(P-POSSUM)和APACHE Ⅱ对近5年来在我科因髋部骨折住院手术的260例老年患者进行回顾性研究,比较三种评分系统对老年患者手术前风险的评估以及预测手术后并发症和病死率的价值.结果 根据POSSUM、DORSSSP预测,并发症发生例数分别为119例、92例,而实际发生并发症84例.前者预测值显著高于实际值,后者预测值和实际发牛差异无统计学意义.POSSUM、P-POSSUM和APACHE Ⅱ系统预测死亡例数分别为16例、10例、12例,实际死亡6例,预测值均明显高于实际值.DORSSSP预测死亡例数9例,最接近实际死亡例数.结论 DORSSSP与术后并发症和病死率有良好的相关性,能够较准确地评估术前风险及预测骨科老年患者手术后并发症和病死率.与POSSUM和APACHE Ⅱ评分比较,DORSSSP预测老年患者骨科手术后并发症和病死率更有效,且更简便实用.

Establishment of a new scoring system for preoperative evaluation of operative risks in the elderly patients with hip fractures

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.
