老年患者下呼吸道医院感染与控制对策

Lower Respiratory Tract Nosocomial Infection among Geriatrics Patients

目的探讨老年患者下呼吸道医院感染的现状,并制定控制对策。方法对158例老年下呼吸道感染患者的临床资料进行调查,分析其感染现状及危险因素。结果我院老年患者医院感染发病率为9.7%,感染部位以下呼吸道为主;158例下呼吸道医院感染老年患者均患有各种慢性消耗性原发基础疾病,痰培养病原菌以革兰阴性杆菌和真菌为主,分别占48.1%和38.9%。结论抵抗力降低、住院时间长、严重的原发基础疾病及不合理使用抗生素是老年患者医院感染的危险因素,应重视老年患者医院感染的监控管理。
