BMJ:医院容量与急性肺栓塞患者结局

2019-08-01 xing.T MedSci原创

由此可见,在急性症状性肺栓塞患者中,入住高容量医院与30天肺栓塞相关死亡率显著降低相关。这些发现可能会对治疗策略产生一定影响。

近日,顶级杂志BMJ上发表了一篇研究文章,研究人员旨在评估通过医院病例体量反映的急性肺栓塞治疗经验与死亡率之间的关系。

研究人员使用2001年1月1日至2018年8月31日期间RIETE登记处的数据进行基于多国人群的队列研究。该研究是在16个国家353家医院完成的。参与者为39257名确诊为急性症状性肺栓塞患者。主要结局指标为疾病诊断后30天内肺栓塞相关死亡率。 

入住大容量医院(每年肺栓塞>40次)的急性症状性肺栓塞患者合并症负担较重。年度医院容量与肺栓塞相关死亡率之间存在显著的负相关。入院率最高的四分位数(即每年>40次肺栓塞)与最低四分位数(<15次肺栓塞)相比,其与30天肺栓塞相关死亡率调整后的可能性降低44%相关(调整风险为1.3% vs. 2.3%;调整后比值比为0.56(95%置信区间为0.33至0.95); P=0.03)。结果在所有敏感性分析中是一致的。在两个四分位数之间30天全因死亡率没有显著降低(调整后的比值比为0.78(0.50至1.22); P=0.28)。幸存者显示低容量和高容量医院之间复发性静脉血栓栓塞(比值比为0.76(0.49至1.19))或大出血(1.07(0.77至1.47))的几率几乎没有变化。

由此可见,在急性症状性肺栓塞患者中,入住高容量医院与30天肺栓塞相关死亡率显著降低相关。这些发现可能会对治疗策略产生一定影响。

Crit care med:什么!ARDS的医院病例数和死亡率有关!

近期,一项发表在杂志Crit care med上的研究探讨了医院年度急性呼吸窘迫综合征病例数量与医院急性呼吸窘迫综合征病死率和个体急性呼吸窘迫综合征住院死亡率的关系。此项研究为回顾性队列研究。选取了2002-2011年美国医疗成本和利用项目的全国住院病例样本。入组患者为急性呼吸窘迫综合征国际疾病分类第9版,临床修改诊断代码(518.82或518.5)和机械通气程序代码(96.70,96.71或96
