Prevalence rates of healthcare-associated infection in a major cancer hospital from 2013 to 2017*

摘要:

目的 统计安徽省肿瘤医院感染发生情况，为更好地防控医院感染提供依据。方法 按照全国医院感染监测网的要求，调查2013～2017年各年现患率，并对数据进行统计分析。结果 2013～2017年医院感染现患率分别为3.96%、3.24%、2.89%、3.83%及4.53%，5年间比较，差异无统计学意义（P?>0.05）。5年来，ICU是现患率最高的科室，下呼吸道是感染率最高部位。抗菌药物平均使用率为22.13%，治疗性用药率增加，预防性用药率降低（P?<0.05）。分离出的病原菌中革兰阴性杆菌数最多，并以鲍曼不动杆菌的多重耐药率最高。年龄、呼吸机、动静脉置管、导尿管、手术是医院感染的相关危险因素（P?<0.05）。结论 现患率调查有助于了解医院感染实际情况，其结果提示应加强重点部门、重点人群的管理，关注下呼吸道感染，规范抗菌药物的合理使用，采取有效的预防措施，降低医院感染发生率。
