老年患者院内获得性肺炎56例临床分析

目的探讨老年人患者医院内获得性肺炎的发病情况、治疗转归及危险因素。方法回顾性分析我院2000年11月至2004年6月56例老年医院内获得性肺炎患者的发病率、发病时间、基础疾病、临床特点、病原菌分布、药物敏感性及治疗转归。结果老年患者医院内获得性肺炎占医院感染的34.3%,发病时间超过30 d者最多占44.6%(25/56),基础疾病以心脑血管疾病、糖尿病、慢性阻塞性肺病为主。死亡率30.4%。结论老年患者医院内获得性肺炎发病率及死亡率均高。住院时间长,原有基础疾病是老年患者医院内获得性肺炎的主要危险因素。

A study on 56 aged patients with nosocomical pneumonia

Aim To detect the incidence,treatment results,risk factors of nosocomical pneumonia in the aged patients.Method We retrospectively analyzed the underlying diseases,clinical characteristics,distribution of pathogenic bacteria,drug sensitivity,trentment results of 56 aged patients with nosocomical pneumonia in our hospital from November 2000 to June 2004.Result The period from admission to the onset was 20.5 days on average.The period of 44.6%(25/56) cases was more than 30 days.The underlying diseases mainly included cerebral vessels and cardiovascular disease,diabetes and COPD.Conclusion The incidence rate and mortality of nosocomical pneumonia are high in the aged patients.The longer length of stay and the underlying diseases are the main risk factors for nosocomical pneumonia in the aged patients.
