老年社区获得性肺炎住院患者临床资料分析

目的总结老年社区获得性肺炎（CAP）患者的临床表现、病原学及预后相关资料。方法回顾分析2002年1月~2007年10月我院收治的CAP患者的临床资料,比较老年CAP患者（年龄）≥60岁）与中青年患者（年龄≤60岁）临床特征的异同。结果成人CAP患者321例,年龄（67±22）岁。老年CAP患者231例,其中73.4%患者合并基础疾病,住院死亡率为12%,肺炎链球菌仍是老年CAP患者的最主要致病菌。与90例中青年CAP患者相比,老年CAP患者入院时出现呼吸困难、急性意识障碍、心率增快及呼吸急促的比例明显增多,病原体分布与中青年CAP患者存在差异。结论老年CAP患者发病率高、并发症多、预后差。临床表现、病原学具有其特殊性,应予足够重视。

Clinical analysis of community-acquired pneumonia in the elderly

Objective To evaluate the clinical features, etiology, and outcome of patients over 60 years old hospitalized for community-acquired pneumonia（CAP）. Methods A retrospective cohort analysis was performed for adult patient hospitalized with CAP in Mi Yun hospital between Jan 2002 and Oct 2007. Differences between ≤ 60 yrs and ≥60 groups were calculated using x2 test. Results A total of 321 patients （166 males） ,with a mean age of （67 ± 22 ）yrs, were enrolled. Of the 231 elderly patients,73.4% had comorbid conditions,mostly cardiovascular diseases and chronic obstructive lung disease, in-hospital mortality was 12 %. The most frequent pathogen was Streptococcus pneumonia in elderly patients. As compared to 90 younger patients （ ≤ 60yrs）, altered mental status, dyspnea, tachypnea and tachycardia on hospital admission were more frequent In the elderly. The etiological distribution was also different between the two groups. Conclusions CAP in elderly patients is a prevalent disease with high incidence of complications and mortality. More attention should be paid to the specific clinical manifestations of this patient population.
