目的对抑郁症患者医院感染的相关因素进行调查分析，以探讨控制感染的相关对策，从而有效地降低抑郁患者医院感染的发生。方法对医院2010年1月一2012年1月的200例抑郁症患者的临床资料进行回顾性分析，观察患者住院期间发生感染的情况，数据均采用SPSS11．0软件进行统计分析。结果200例患者中有18例发生医院感染，感染率为9．00％；感染部位主要集中于呼吸道、胃肠道、泌尿道以及皮肤等其他组织部位，其中呼吸道、胃肠道和泌尿道分别占38．89％、33．33％和16．66％；18例患者共分离出22株病原菌，其中革兰阴性菌占72．73％，革兰阳性菌占22．73％，真菌1株占4．54％；医院感染危险因素主要是患者年龄、是否有基础疾病、意识状态、住院季节、住院天数、广谱抗菌药物的使用及侵入性操作。结论抑郁症患者医院感染的危险因素众多，以呼吸道和消化道多见，需要进行加强管理，采取干预措施，做好防治工作。
