Crit Care:SOFA评分的早期变化可作为败血症患者28天死亡率的预后指标

2019-12-05 xing.T MedSci原创

由此可见,ΔSOFA是28天死亡率有效地早期预测标志物,可以作为未来败血症试验的终点。

自脓毒症3标准发布以来,序贯器官衰竭评估(SOFA)评分改变已成为确诊脓毒症的关键组成部分。因此,可以认为这种改变的逆转(ΔSOFA)可能反映出败血症反应,并且可以作为干预试验中疗效的指标。近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,研究人员旨在评估ΔSOFA对28天死亡率的预测性能。(在线使用重症患者SOFA评分表

研究分析了两项先前发表的随机对照试验的数据:第一项研究报告了重度革兰阴性感染患者,其作为衍生队列,第二项研究报告了呼吸机相关性肺炎患者,其作为验证队列。此分析仅纳入了根据脓毒症3标准确诊的脓毒症患者。在第1、2、3、5、7、14和28天计算了SOFA得分。

研究人员纳入了衍生队列中的448名患者和验证队列中的199名患者。第1天SOFA评分的平均值分别为6.06±4.07和7.84±3.39,而28天死亡率分别为22.8%和29.6%。在衍生队列中,ΔSOFA评分预测死亡率的最早时间点是第7天(AUROC(95%CI)为0.84(0.80-0.89);p<0.001)。预测的最佳权衡是有25%的改变(敏感性为78%,特异性为80%)。入院SOFA降低少于25%与死亡率增加相关(死亡比值比为14.87)。

由此可见,ΔSOFA是28天死亡率有效地早期预测标志物,可以作为未来败血症试验的终点。
