摘要
目的探讨医院感染危险因素,旨在为医院感染防控提供参考。方法回顾性收集该院2015年1月至2016年12月医院感染680例患者资料,从年龄、住院科室、感染部位等方面分析医院感染特点。结果 680例医院感染患者占全部住院患者(40 657例)的1.67%,其中61～80岁316例(医院感染率为2.47%);综合重症监护病房(ICU)感染率最高(24.90%),其次是肾病科(4.99%);感染部位最多例次的为下呼吸道(413例次),其次为泌尿道、表浅切口(二者均68例次);病原学送检率为45.03%,检出病原菌190株,排在前5位的依次为大肠埃希菌(47株)、肺炎克雷伯菌(28株)、铜绿假单胞菌(23株)、金黄色葡萄球菌(22株)及鲍曼不动杆菌(16株);Logistic回归分析发现年龄大于60岁、住院时间大于60d、导尿管留置、经外周静脉置入中心静脉导管(PICC)、气管切开、肠内营养为医院感染发生危险因素。结论医院应重点预防患者下呼吸道医院感染发生,加强ICU等重点科室的医院感染管理。
Objective To explore the risk factors of nosocomial infections to provide a reference for prevention and control of nosocomial infection.Methods The data of 680 patients with nosocomial infection in this hospital from January 2015 to December 2016 were retrospectively collected.The characteristics of nosocomial infection were analyzed from the aspects of age,hospitalization department,infection site,etc.ResultsA total of 680 cases of nosocomial infection accounted for 1.67%（680/40 657）of all hospitalization patients,including 316 cases（nosocomial infection rate was 2.47%）of 61-80 years old.The infection rate was the highest in ICU（24.90%）,followed by the nephrology department（4.99%）.For infection sites,the maximal cases-times in infection site was lower respiratory tract（413 case-times）,followed by urinary tract and superficial incision（each 68 case-times）.The pathogenic detection rate was 45.03%,and 190 strains of pathogens were detected.The top five places were Escherichia coli（47 strains）,Klebsiella pneumoniae（28 strains）,Pseudomonas aeruginosa（23 strains）,Staphylococcus aureus（22 strains）and Bauman Acinetobacter（16 strains）.Logistic regression analysis showed that age larger than 60 years old,hospitalization time longer than 60 d,indwelling urinary catheter,peripherally inserted central catheter（PICC）,tracheotomy and enteral nutrition were the risk factors for nosocomial infection occurrence.Conclusion Hospital should put the emphasis on preventing nosocomial infection of lower respiratory tract and strengthen the nosocomial infection management of key departments like ICU.
