Appropriate hand hygiene (HH) is key to reducing healthcare-acquired infections. The World Health Organization (WHO) recommends education and training to improve HH knowledge and compliance. Physicians are ranked among the worst of all healthcare workers for compliant handrubbing with its origin probably being the failure to learn this essential behavior during undergraduate medical studies. This study evaluated if the use of Ultraviolet-cabinets (UVc) for fluorescent-alcohol-based handrubs (AHR) during an undergraduate medical student training improved the compliance rate to the WHO hand hygiene recommendations (completeness of AHR application and HH opportunities). This randomized trial compared a HH training with personal feedback (using UVc) to a control group. The first year, the students (2nd degree) were convened by groups (clusters) of 6–9 for a demonstration of the correct execution of WHO procedure. Randomization by cluster was done prior HH training. In the control group, the students hand rubbed under visual supervision of a tutor. In the intervention group after the same visual supervision, completeness of fluorescent-AHR hand application was recorded under UVc and was shown to the student. The intervention group had free access to the UVc until complete application. HH practices were included in simulation sessions for the both groups. One year after (3rd degree), all the students were asked to hand rub with fluorescent-AHR. A tutor (blinded to the study group) assessed the completeness of hand application under UVc and the compliance with the WHO opportunities. Complete application of AHR was defined as fluorescence for all the surfaces of hands and wrists. 242 students participated (140 in the intervention group and 102 in the control group). One year after the initial training, the rate of complete application of AHR was doubled in the intervention group (60.0% vs. 30.4%, p < 0.001). In a multivariate analysis which included gender, additional HH or UVc training, surgical traineeship and regular use of AHR, the hazard ratio for the intervention was 3.84 (95%CI: 2.09–7.06). The compliance with the HH WHO’s opportunities was increased in the intervention group (58.1% vs. 42.4%, p < 0.018). Using UVc for undergraduate medical students education to hand hygiene improves their technique and compliance with WHO recommendations.

使用紫外线柜可以提高本科医学生对世界卫生组织手部卫生建议的依从性:一项随机对照试验。

适当的手部卫生 (HH) 是减少医疗保健获得性感染的关键。世界卫生组织 (WHO) 建议进行教育和培训,以提高 HH 知识和依从性。医生被列为所有医护人员中最不合规的搓手,其根源可能是在本科医学学习期间未能学会这种基本行为。该研究评估了在本科医学生培训期间将紫外线柜 (UVc) 用于荧光酒精洗手液 (AHR) 是否提高了对 WHO 手部卫生建议的遵守率(AHR 应用的完整性和 HH 机会)。这项随机试验将带有个人反馈(使用 UVc)的 HH 培训与对照组进行了比较。第一年,学生(第二学位)由 6-9 人的小组(集群)召集,以展示 WHO 程序的正确执行。在 HH 训练之前按集群进行随机化。在对照组中,学生在导师的视觉监督下搓手。在相同视觉监督后的干预组中,在 UVc 下记录荧光 AHR 手部应用的完整性并向学生展示。干预组可以免费使用 UVc,直到完成应用。HH 实践包括在两组的模拟课程中。一年后(第三学位),所有学生都被要求用荧光 AHR 进行手擦。一位导师(对研究小组不知情)评估了 UVc 下手工应用的完整性以及与 WHO 机会的合规性。AHR 的完整应用被定义为手和手腕所有表面的荧光。242 名学生参与(干预组 140 名,对照组 102 名)。初始培训一年后,干预组的 AHR 完全应用率翻了一番(60.0% 对 30.4%,p < 0.001)。在包括性别、额外的 HH 或 UVc 培训、外科培训和定期使用 AHR 的多变量分析中,干预的风险比为 3.84(95%CI:2.09-7.06)。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。242 名学生参与(干预组 140 名,对照组 102 名)。初始培训一年后,干预组的 AHR 完全应用率翻了一番(60.0% 对 30.4%,p < 0.001)。在包括性别、额外的 HH 或 UVc 培训、外科培训和定期使用 AHR 的多变量分析中,干预的风险比为 3.84(95%CI:2.09–7.06)。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。242 名学生参与(干预组 140 名,对照组 102 名)。初始培训一年后,干预组的 AHR 完全应用率翻了一番(60.0% 对 30.4%,p < 0.001)。在包括性别、额外的 HH 或 UVc 培训、外科培训和定期使用 AHR 的多变量分析中,干预的风险比为 3.84(95%CI:2.09–7.06)。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。AHR 的完全应用率在干预组中翻了一番(60.0% 对 30.4%,p < 0.001)。在包括性别、额外的 HH 或 UVc 培训、外科培训和定期使用 AHR 的多变量分析中,干预的风险比为 3.84(95%CI:2.09–7.06)。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。AHR 的完全应用率在干预组中翻了一番(60.0% 对 30.4%,p < 0.001)。在包括性别、额外的 HH 或 UVc 培训、外科培训和定期使用 AHR 的多变量分析中,干预的风险比为 3.84(95%CI:2.09–7.06)。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。干预组对 HH WHO 机会的依从性增加(58.1% 对 42.4%,p < 0.018)。使用 UVc 对本科医学生进行手部卫生教育可以提高他们的技术和对 WHO 建议的遵守。
