530-8.Epub2003Mar28.,Sepsis2.0=感染SIRS会议提出了包括20余条临床症状和体征评估指标构成的诊断标准,即Sepsis2.0。
然而该标准过于复杂,且缺乏充分的研究基础和科学研究证据支持,并未得到临床认可和应用。

580-637.,2008,2004,脓毒症诊断标准的“争议”,方法:
通过对2000年至2013年澳大利亚和新西兰172个重症加强治疗病房(ICU)近120万例患者的数据分析,根据是否满足2条全身炎症反应综合征(SIRS)的诊断标准将感染伴器官功能障碍的患者分为SIRS阳性和SIRS阴性两组。
结果:
在近11万例感染伴器官功能障碍的患者中,87.9%为SIRS阳性,12.1%为SIRS阴性,在14年内两组患者的临床特征和病死率变化相似。
校正分析显示,患者病死率随着满足SIRS标准项目的增加呈线性增高。
结论:
该研究说明现有脓毒症标准有可能遗漏约1/8的感染伴器官功能障碍患者,且该标准不能确定病死率增加的临界点,这提示当前脓毒症的筛查标准的特异性不佳。
