老年患者留置尿管致尿路感染的原因及对策

目的探讨老年住院患者留置尿管致尿路感染的相关因素,寻求有效的预防措施,以减少尿路感染的发生。方法对176例留置尿管的老年住院患者进行目标性监测,对其中发生尿路感染的患者就其相关因素进行分析。结果 176例留置尿管患者中有39例发生尿路感染,感染率为22.16%。女性明显高于男性(P<0.05﹚,留置尿管时间越长感染率越高(P<0.05﹚,不同基础疾病患者尿路感染发生率差异有统计学意义(P<0.05﹚。39例尿路感染共检出病原菌32株,其中以大肠埃希菌为主,占37.50%。结论老年患者尿路感染的发生与性别、基础疾病、尿管留置时间有关;加强尿路感染高发人群的目标性监测,针对易感因素制定相关干预措施,可降低其发生率。

Causes and Countermeasures of Indwelling Catheter-associated Urinary Tract Infection in Elderly Patients

Objective To investigate the related factors for indwelling catheter-associated urinary tract infection （CHUTI）in hospitalized elderly patients, and to discuss the preventive measures for urinary tract infection. Methods Objective monitoring was performed in 176 hospitalized elderly patients who had indwelling urinary catheters. The related factors for CHUTI were analyzed. Results Among the 176 patients, urinary tract infection occurred in 39 （22.16%）.The incidence in females was significantly higher than that in males（P〈0.05 ）. Moreover ,the incidence increased with prolonged indwelling time （P〈0.05）. There were significant differences in the incidence of urinary tract infection among patients with different underlying diseases（P〈0.05）. Among the 39 patients with urinary tract infection, 32 pathogenic strains were detected and Escherichia coli was the most frequently detected bacterial pathogens （37.50%）.Conclusion Urinary tract infection is correlated with the gender, underlying diseases and indwelling time in elderly patients. Strengthening objective monitoring and developing targeted interventions can reduce the incidence of urinary tract infection.
