导管治疗显著增加了老年患者无症状细菌性尿病 (ASB) 的风险,即使在内置尿管导管 (IUC) 移除后. 与导管结合的Enterococcus物种殖民可能持续超过四周的移除后.
科学领域:
- 老年医学 老年医学
- 传染性疾病 传染性疾病
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
背景情况:
- 住宿性尿导管 (IUC) 在老年护理中很普遍,增加了无症状细菌尿 (ASB) 和尿路感染 (UTI) 的风险.
- 在老年患者的IUC移除后,ASB的发生尚未研究.
- 这项研究调查了ASB和UTI与这一人口群体的导管化史有关.
研究的目的:
- 在老年患者中比较ASB和尿路感染率,有和没有导管史.
- 在老年患者中识别与ASB相关的因素.
- 为了了解ASB在IUC移除后的持久性.
主要方法:
- 分析了来自斯德哥尔摩两个康复病房的196名无症状老年患者.
- 收集的数据包括导管病史,抗生素使用和糖尿病.
- 分析了尿液样本,并通过患者记录追踪尿路感染的发生情况.
主要成果:
- 与没有最近使用IUC (20.6%,P=0.018) 的患者相比,在有导管病史的患者中,ASB的发生率明显高 (36.5%).
- 肠球菌更频繁地被发现在有导管病史的患者中.
- 导管是ASB的显著预测因素 (OR 2.79,P=0.008),在调整混因子后仍然存在.
结论:
- 导管与ASB密切相关,这种情况即使在IUC移除后也会持续下去.
- 结肠杆菌物种的殖民,可能与导管治疗有关,可能在IUC移除后至少持续四周.
- 研究结果强调了导管对老年患者细菌尿的长期影响.
