健康护理相关性肺炎新进展

摘要

健康护理相关性肺炎(HCAP)作为肺炎的一种独立类型,其多重耐药病原体感染风险、初始抗菌药物治疗及临床预后有别于社区获得性肺炎(CAP)及医院获得性肺炎(HAP).本文综述近几年HCAP研究新进展及目前对其病原学和临床预后的争议,以加深临床医师对HCAP的认识.%As a new entity of pneumonia, healthcare associated pneumonia is different from community acquired pneumonia and hospital acquired pneumonia in terms of frequency of multidrug -resistant pathogens, initial antibiotic treatment and clinical outcomes. This article reviews research progress of HCAP in recent years as well as controversies on microbial etiology and outcomes, in order to improve the recognition of HCAP for clinicians.
