实施尿路感染 (UTI) 面板显著减少了尿培养和导管相关的尿路感染 (CAUTIs). 这种对CAUTI病例的积极影响甚至在COVID-19大流行期间也持续存在.
科学领域:
- 传染性疾病 传染性疾病
- 改善医疗保健质量 改善医疗保健质量
- 流行病学 流行病学
背景情况:
- 导管相关的尿路感染 (CAUTIs) 代表了与医疗保健相关的感染负担.
- 需要有效的策略来优化诊断方法并减少CAUTI发病率,特别是在第三级护理机构.
- 随着COVID-19大流行,感染控制实践和患者管理面临挑战.
研究的目的:
- 引入和评估新型尿路感染 (UTI) 专家组对CAUTI发病率的影响.
- 评估尿路感染小组在减少尿培养 (UC) 和CAUTI发病率方面的有效性.
- 为了确定UTI小组对CAUTI的影响是否在COVID-19大流行期间持续存在.
主要方法:
- 采用了准实验性设计,比较了三个时期:在COVID-19大流行期间的前面板,后面板实施和后面板.
- 来自三级护理住院患者的数据使用波桑回归和中断时间序列 (ITS) 分析进行了分析.
- 关键指标包括导管日 (CD),尿液培养 (UC),每1000个CD和患者日 (PD) 的CAUTI率以及国家卫生安全网络标准化感染比率 (SIR).
主要成果:
- 实施尿路感染小组导致UC每1000名PD显著下降 (36.9至16.6).
- 每1000个CD的CAUTI率在面板后实施后下降了40% (P < .001).
- 尽管COVID-19期间的CAUTI率增加了13%,但CAUTI率仍然比分组前水平低32% (P = .02).
结论:
- 输尿管道感染小组的引入与UC和CAUTI的实质性减少有关.
- 在COVID-19流行病的艰难时期,UTI小组对CAUTI减少的积极影响一直保持不变.
- 这一战略证明了改善医院环境中的尿路感染诊断和感染控制的成功方法.
