目的了解内蒙古自治区医院住院患者医院感染及抗菌药物使用情况,为加强医院感染管理提供参考。方法采用横断面调查方法,选择2012年3月至10月期间某个工作日对66所医院的住院患者医院感染现患率进行调查。结果调查当日66所医院共有住院患者27 285例,实查26 940例,实查率98.74%。共查出医院感染患者553例、586例次,医院感染现患率为2.05%、例次感染率2.18%。下呼吸道为医院感染高发部位;感染病原菌以大肠埃希菌、肺炎克雷伯菌、铜绿假单胞菌、金黄色葡萄球菌等为主。抗菌药物平均使用率为36.09%,治疗用药患者病原学标本送检率为23.82%。结论内蒙古自治区66所医院住院患者医院感染现患率在可控制范围,随医院床位数增加,感染现患率增加;应提高病原学标本送检率和药敏试验率。
Objective To understand the prevalence of nosocomial infections and antibacterials in hospital in Inner Mongolia Autonomous Region and to provide references for strengthening the management of nosocomial infections. Methods A cross-sectional survey method was used to investigate the prevalence of nosocomial infection among inpatients in 66 hospitals on a working day from March to October 2012. Results On the day of investigation, there were 27 285 inpatients in 66 hospitals, accounting for 26 940 cases and the actual examination rate was 98.74%. A total of 553 cases of hospital infection were detected, 586 cases, the prevalence of hospital infection was 2.05%, the second case infection rate was 2.18%. Lower respiratory tract as a high incidence of nosocomial infections; pathogenic bacteria to Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and other mainly. The average use rate of antibacterials was 36.09%. The rate of etiological specimens in treatment patients was 23.82%. Conclusions The prevalence of nosocomial infection in 66 inpatients in Inner Mongolia Autonomous Region is within the controllable range. As the number of hospital beds increases, the prevalence of nosocomial infections increases; the rate of etiological examination and the rate of drug susceptibility testing should be increased.
