常规的卫生观察可以预测疫情爆发. 在非疫情期间的高遵守率 (超过97%) 表明有保护作用,有助于早期检测感染风险.
科学领域:
- 预防和控制感染的预防和控制.
- 医院流行病学 医院流行病学
- 微生物学 微生物学
背景情况:
- 手部卫生,手套和围的使用以及服装规范的遵守对于预防医疗保健相关感染至关重要.
- 多种耐药性细菌,如Acinetobacter baumannii,在临床环境中构成重大威胁.
- 烧伤中心需要严格的感染控制,因为患者的脆弱性.
研究的目的:
- 分析卫生遵守情况及其与烧伤中心爆发的关联.
- 探索使用例行卫生观察作为细菌传播的早期预警系统.
- 评估感染控制干预措施对卫生不合规行为的影响.
主要方法:
- 直接观察员工遵守手部卫生,手套使用,围使用和着装规范.
- 间断时间序列分析 (2013-2017年和2018-2022年) 以评估干预的有效性.
- 在四到六个月期间计算滚动总和卫生错误的第90百分位数.
主要成果:
- 13,216个观察结果显示,卫生标准的遵守率在70%-100%之间.
- 感染控制干预措施显著减少了疫情爆发后的违规行为,并带来了持久的改善.
- 不符合规定的滚动总和 (7-11个错误的门) 预测了Acinetobacter baumannii的爆发.
结论:
- 超过97%的合规水平与无爆发期有关,这表明它起到了保护作用.
- 专注于不合规指标可以促进早期检测增加的疫情风险.
- 常规的卫生观察和滚动金额可以指导预防性干预.
