老年患者尿管相关性泌尿系统医院感染相关因素分析

Analysis of related factors of urinary catheter related urinary system nosocomial infections in elderly patients

目的探讨老年性尿管相关性感染患者的相关因素,为控制老年患者泌尿系统感染提供依据。方法选择医院2014年1月-2016年12月患者中发生泌尿系统感染的患者137596例为研究对象,对导致老年导尿管相关性泌尿系统感染的发生相关因素进行分析。结果共监测137596住院患者,60岁以上患者38602例,占总住院人数的28.05%,发生医院感染934例,医院感染率2.42%;60岁以上患者插尿管患者564例,占1.46%,插管总日数共8070天,发生尿管相关性泌尿系统感染共50例,千日感染率6.20‰。留置尿管时间、住院时间、抗菌药物使用种类、入住ICU天数为留置尿管老年患者泌尿系统感染的相关因素(P<0.05)。结论实施有效地预防与控制干预措施更能缩短插管总日数,规范合理使用抗菌药物,可降低老年性尿管相关性泌尿系统感染率。

OBJECTIVE To investigate the related risk factors of senile urinary tract infections,so as to provide evidence for the control of urinary tract infections in elderly patients.METHODS A total of 137596 cases of patients with urinary tract infections from Jan.2014 to Dec.2016 were selected as research objects.Risk factors associated with urinary catheter related urinary tract infections in elderly patients were analyzed.RESULTS A total of 137596 hospitalized patients were monitored,including 38602 patients aged 60 years and above accounting for 28.05% of the total number of hospitalized patients.There were 934 cases of nosocomial infections,and the rate of nosocomial infections was 2.42%.There were 564 cases of urethral catheterization in patients aged 60 years and above,accounting for 1.46%.The total day of intubation was 8070 days.There were 50 patients of urinary catheter related urinary tract infections,with thousand-day infection rate of 6.20‰.Time of indwelling urinary catheter,time of hospitalization,types of antimicrobial drug,and the time of ICU days were risk factors for the occurrence of senile urinary tract infections with indwelling catheter（P〈0.05）.CONCLUSION Effective prevention and control intervention can shorten the total number of intubation days,and rational use of antibiotics can reduce the incidence of urinary system infections in the elderly patients indwelling catheter.
