【摘要】目的评估院前指数(PHI)在急性创伤住院患者中的应用价值。方法随机抽取急性创伤住院患者1802例,分别行PHI和损伤严重度评分(ISS)。以出院日期为观察终点,结局为观察指标,利用受试者工作特征曲线(ROC曲线)找出最佳截断点,以ISS为参照,计

算患者相应的预测指标,比较PHI预测急性创伤住院患者预后的价值。结果 PHI与ISS评分ROC曲线下面积分别为0.871(95% CI :0.855~0.886)、0.792(95% CI :0.773~0.811),二者差异具有统计学意义( Z =2.674,P=0.007);判断急性创伤住院患者“潜在危重症”的最

佳截断点分别为PHI≥4分、ISS≥22分;PHI对危重症患者死亡预测的的灵敏度优于ISS

(χ2=6.975,P=0.008),而特异度、准确度与ISS差异无统计学意义(P>0.05)。结论 PHI对急性创伤住院患者的预后评估具有较高的分辨能力,并优于ISS评分;PHI评分操作简便、易于掌握、反映病情及时可靠,有利于院内创伤患者危重症的早期发现与救治。

【Abstract】Objective To evaluate the application value of prehospital index (PHI) in hospitalized patients with acute trauma.Methods A study was done in 1802 hospitalized patients with acute trauma by random sampling. PHI and injury severity score (ISS) were made respectively. Receiver operating characteristic curve (ROC curve) was used for detecting optimal cut-off point by taking the date of discharge as the endpoint and the outcome as observed indicator. In order to compare the predicting prognosis value of PHI in hospitalized patients with acute trauma, the corresponding predicting indicators were calculated and ISS was used for reference.Results The area under the ROC curve was 0.871(95% CI :0.855-0.886)by the score of PHI and 0.792(95%

CI :0.773-0.811)by the score of ISS, and there was statistically difference between the two
