老年社区获得性肺炎临床特点分析

Retrospective analysis of clinical data of elderly patients hospitalized with community acquired pneumonia

目的探讨老年社区获得性肺炎（CAP）的临床特点。方法回顾性调查2000年1月至2006年12月入院治疗的289例老年社区获得性肺炎病例，分析其年龄、基础疾病、临床表现、影像学特点、病原菌分布及预后。结果289例老年CAP，男216例（74．74％），女73例（25．26％），年龄60～99岁，平均（79．5±15．5）岁。老年CAP患者临床表现多样化，多有基础疾病，以高血压、冠心病、脑血管疾病最为常见。患者痰送检185例，检出病原菌99例，以G^-杆菌为主。结论老年CAP住院患者基础疾病多,临床表现不典型,病原菌复杂,且合并症多、死亡率高，应当引起医生的高度重视。

Objective To investigate the characteristic of elderly patients with community acquired pneumonia（CAP）. Methods Retrospective study was perfromed on the clinical data of 289 elderly patients with CAP, including their age, underlying disease, clinical situation, imaging feature, pathogenic bacteria and prognosis. All patients were treated in our department from January 2000 to December 2006. Results The age of 289 cases,216 males,73 females,ranged from 60-69 years,with an average age of 79.5±15.5 years. The clinical situation of the elderly patients with community acquired pneumonia was to diversify. A few of them had underlying disease, such as hypertension, coronary heart disease occurred. Strains of pathogenic bacteria were detected in 185 cases. The pathogenic bacteria was identified in 99 cases, and the most pathogenic bacteria is Gbacillus. Conclusion The clinical symptoms and pathogenic causes of elderly CAP cases with concomitant dis- ease are not typical, it has more complications and high death rate. Therefore, much more attention should be paid to it.
