OBJECTIVE
To evaluate the discriminatory power of TraumaSCAN-Web, a system for assessing penetrating trauma, using retrospective multi-center case data for gunshot and stab wounds to the thorax and abdomen.
METHODS
80 gunshot and 114 stab cases were evaluated using TraumaSCAN-Web. Areas under the Receiver Operator Characteristic Curves (AUC) were calculated for each condition modeled in TraumaSCAN-Web.
RESULTS
Of the 23 conditions modeled by TraumaSCAN-Web, 19 were present in either the gunshot or stab case data. The gunshot AUCs ranged from 0.519 (pericardial tamponade) to 0.975 (right renal injury). The stab AUCs ranged from 0.701 (intestinal injury) to 1.000 (tracheal injury).
目的
利用胸部和腹部枪伤及刺伤的回顾性多中心病例数据，评估用于评估穿透性创伤的系统TraumaSCAN-Web的鉴别能力。
方法
使用TraumaSCAN-Web对80例枪伤和114例刺伤病例进行评估。针对TraumaSCAN-Web中建模的每种情况计算受试者操作特征曲线下面积（AUC）。
结果
在TraumaSCAN-Web建模的23种情况中，有19种出现在枪伤或刺伤病例数据中。枪伤的AUC范围为0.519（心包填塞）至0.975（右肾损伤）。刺伤的AUC范围为0.701（肠损伤）至1.000（气管损伤）。
