目的评价 APACHEⅡ评分系统对危重病人的监测意义。方法应用回顾分析对 APACHEⅡ评分系统的预报能力进行评价,以效验力和辨析力来明确其适用价值。结果回顾性分析306例患者,其预测死亡的灵敏度85%,特异度88.2%,准确度86.6%,经 Hosmer Lemeshow 拟合优度检验,x~2值=2.968,P 值=0.936,其受试者工作特性曲线下面积为0.954。结论 APACHEⅡ评分系统可以作为危重病情判断的一种通用手段,用于危重病救治工作 Objective To evaluate the significance of APACHE Ⅱ scoring system in monitoring critically ill patients. Methods The retrospective analysis was used to evaluate the ability of APACHE Ⅱ scoring system to forecast its effectiveness. Results A retrospective analysis of 306 patients showed a sensitivity of 85%, a specificity of 88.2% and an accuracy of 86.6% for predicting death. According to the Hosmer Lemeshow goodness-of-fit test, x ~ 2 = 2.968 and p = 0.936. The area under the operating characteristic curve is 0.954. Conclusion APACHE Ⅱ scoring system can be used as a common means of judging critically ill patients for the treatment of critical illness
