2017年10月,发表在《Am J Respir Crit Care Med》上的一项回顾性研究,考察了败血病患者早期应用抗菌药物时机与住院死亡率的相关性。

目的:评估败血病患者急诊入院在6 h内接受抗菌药物治疗的时机与死亡率之间的关系。

方法:2010和2013年间,对加利福尼亚州北部的21家急诊室的35000名随机筛选的败血病住院患者开展回顾性研究。主要暴露是急诊入院后6 h内给予抗菌药物。主要结局是校正的院内死亡率。研究人员使用详细的生理数据量化在住院内1 h的恶化程度,并根据抗菌药物给药时机和患者因素,采用逻辑回归估算住院死亡率的比值。

检测和主要结果:平均抗菌药物给药时间是2.1 h(四分位间距,1.4-3.1 h)。入院后抗菌药物治疗每延迟1 h的住院死亡率校正比值比是1.09(95%置信区间[CI],1.05-1.13)。败血病的抗菌药物治疗每延迟1 h相关的绝对死亡率会增加0.3%(95%CI,0.01-0.6%;P=0.04),严重败血病增加0.4%(95%CI,0.1-0.8;P=0.02),休克增加1.8%(95%CI,0.8-3.0%;P=0.001)。

结论:在一项大型、当代多中心的急诊败血病患者样本中,抗菌药物每小时的给药延迟与住院死亡率的增加相关,即使是在6 h内接受抗菌药物。危险程度随败血病严重程度增加而升高。
