目的了解留置导尿相关尿路感染的易感因素,调查尿路感染的病原菌检出及其耐药现状。方法采用回顾性调查和多元分析方法,对2011年度某医院住院确诊的269例医院内获得性尿路感染患者进行调查。结果269例医院内获得性尿路感染患者老年患者居多,≥76岁的患者占28.6%;患者多有基础疾病,其中脑出血占34.2%;接受泌尿道插管的患者中,发生医院内获得性尿路感染者占81.2%。医院内获得性尿路感染标本中,检出的致病菌居前3位的依次为大肠埃希菌、屎肠球菌和真菌。结论医院内获得尿路感染高发因素主要为高龄、基础疾病严重和泌尿道插管,应据此有针对性地采取防控措施。
Objective To investigate the predisposing factors of urinary tract infection associated with catheterization and to investigate the detection of pathogenic bacteria in urinary tract infection and its drug resistance status. Methods A retrospective survey and multivariate analysis were conducted to investigate 269 cases of hospital acquired urinary tract infection who were hospitalized in 2011 in a hospital. Results Among the 269 patients with acquired urinary tract infection, the majority of elderly patients accounted for 28.6% of patients ≥76 years of age. Most patients had underlying diseases, of which 34.2% had intracerebral hemorrhage. Among the patients receiving urinary catheterization, Sexual urinary tract infection accounted for 81.2%. Hospital acquired urinary tract infection specimens, the top three pathogenic bacteria detected in turn were Escherichia coli, Enterococcus faecium and fungi. Conclusions The high incidence of urinary tract infection in hospital is mainly due to advanced age, serious underlying diseases and urinary tract intubation. Therefore, prevention and control measures should be taken accordingly.
