Crit Care Med:脓毒血症患者发病前服用阿司匹林竟能降低死亡风险!

2017-11-21 王淳 环球医学

2017年11月,发表在《Crit Care Med》上的一项Meta分析,研究了住院患者脓毒血症发病前乙酸水杨酸(阿司匹林)的使用对脓毒血症相关死亡的影响。研究结果证实:脓毒血症发病前服用阿司匹林的患者死亡风险降低范围是2%-12%,并且低剂量阿司匹林可作为脓毒血症患者一个降低死亡率的策略。

2017年11月,发表在《Crit Care Med》上的一项Meta分析,研究了住院患者脓毒血症发病前乙酸水杨酸(阿司匹林)的使用对脓毒血症相关死亡的影响。研究结果证实:脓毒血症发病前服用阿司匹林的患者死亡风险降低范围是2%-12%,并且低剂量阿司匹林可作为脓毒血症患者一个降低死亡率的策略。

目的:主要目的是在已发表的观察性队列数据开展一项Meta分析,描述住院患者脓毒血症发病前阿司匹林的使用与死亡率之间的关系。

研究筛选:本研究纳入了报道了使用阿司匹林的脓毒血症患者的死亡率,以及先前未使用阿司匹林的脓毒血症患者对照组。

数据来源:15项研究描述基于医院的队列(n=17065),另有一项是基于保险的大型数据库(n=683421)。所有纳入研究的个体水平患者数据被合并。

数据提取:以研究水平1:1倾向评分匹配的倾向性分析被开展,最稳定可用的协变量被认为与阿司匹林相关。采用Meta分析,以评估阿司匹林对脓毒血症相关死亡的汇总平均治疗作用。

数据拟合:Meta分析显示阿司匹林使用与死亡风险降低7%(95%CI,2-12%;p=0.005)相关,存在相当大的统计学异质性(I2=61.6%)。

结论:这些结果是一致的,脓毒血症发病前服用阿司匹林的患者死亡风险降低范围是2%-12%。这个关联预测了一个明确的研究结果,即低剂量阿司匹林可作为脓毒血症患者一个降低死亡率的策略。
