全身性感染的流行病学进展

全身性感染在感染患者中非常常见，尤其是入住ICU的患者。相关研究表明，全身性感染的发病率呈上升趋势。随着临床医师对发病机制认识的加深与支持治疗手段的不断进步，全身性感染的病死率有所下降，但由于发病率的增加，因全身性感染而死亡的人数仍在逐年增加。对于存活的全身性感染患者，由于健康状况欠佳，社会功能、情感职能下降，其远期的生命质量也常明显下降。全身性感染患者一旦合并器官功能衰竭，常需要入住ICU，消耗大量的医疗资源和医疗费用，给患者家庭及社会造成沉重的疾病及经济负担。本文将对全身性感染的流行病学进展进行回顾，以进一步加深对全身性感染的了解，并为医疗资源的分配提供依据。

Updates of Epidemiology of Sepsis

Sepsis is common in patients with infection, especially in those ones admitted into intensive care unit (ICU). Studies have found that the incidence of sepsis is on the raise. Despite better understanding of the pathogenesis and advances in mordern techonlogy of supporting therapy have led to an improved outcome of individuals suffering from sepsis , the total number of deaths from sespis is increasing. Even survived from the disease, the life quality of the patients may decrease obviously bacause of the decline of physical conditions, social function, role emotional, etc. Many septic patients are hospitalized in ICUs as they complicated with organ dysfunction/failure, which would bring about tremendous consumption of health resources and dramatic disease burdens to their families and our society. We will summarize the incidence and outcome of sepsis for the purpose of further understanding of the disease and providing evidence for health care resource allocation.
