BACKGROUND
For effective prevention of nosocomial transmissions continuous training and motivation of health care workers (HCW) are essential to maintain and increase compliance with high rates of hand hygiene. The use of Virtual Reality (VR) seems to be a contemporary and interesting approach for hand hygiene training in HCW. Nevertheless, HCW should be asked for their preferences as intrinsic motivation is essential for compliance with hand hygiene and training success should be evaluated.
METHODS
A prospective, cross-controlled trial was conducted at two wards in a tertiary care hospital comparing a conventional lecture for hand hygiene to the use of VR. Both interventions were assigned at ward level. Primary outcome was HCW acceptance, which was verified in a third ward, secondary outcomes were hand rub consumption and compliance to indications for hand hygiene as proposed by WHO.
RESULTS
In summary, 81 trainings were conducted, 48 VR trainings and 33 trainings by lecture. VR training was well accepted by HCW with a mean score in all items from 3.9 to 4.3 (out of 5). While most HCW (69%) would prefer VR teaching rather than a lecture for hand hygiene education, only 4% preferred the traditional lecture. 400 observations of hand hygiene indications were made, 50 before intervention and 50 after each intervention at the three wards. Mean proportion of correct and indication-appropriate performances was 81% before intervention, 87% after VR training (p = 0.12), and 95% after lecture (p = 0.04). Hand rub consumption did not change significantly in any group.
CONCLUSIONS
Due to the high acceptance of VR technology among healthcare workers, it can be considered an interesting addition to conventional lectures for teaching hand hygiene. However, the hypothesis that VR teaching has a higher impact on hand rub use and hand hygiene compliance than a conventional lecture cannot be confirmed.
背景
为了有效预防医院感染，持续培训和激励医护人员（HCW）对于保持和提高高水平手卫生依从性至关重要。虚拟现实（VR）的使用似乎是一种针对 HCW 进行手卫生培训的现代且有趣的方法。然而，应该征求 HCW 的意见，因为内在动机对于手卫生依从性很重要，并且应该评估培训的成功。
方法
在一家三级护理医院的两个病房中进行了一项前瞻性、对照试验，将常规的手卫生讲座与 VR 的使用进行了比较。两种干预措施均在病房层面进行分配。主要结果是 HCW 的接受程度，在第三个病房进行了验证，次要结果是手消毒剂的消耗量和符合世界卫生组织（WHO）提出的手卫生指征的依从性。
结果
共进行了 81 次培训，其中 48 次为 VR 培训，33 次为讲座。VR 培训受到 HCW 的广泛认可，所有项目的平均得分为 3.9 到 4.3（满分 5 分）。尽管大多数 HCW（69%）更喜欢 VR 教学而不是讲座来进行手卫生教育，但只有 4%的人更喜欢传统讲座。在三个病房中，对 50 次干预前和 50 次干预后手卫生指征进行了 400 次观察。干预前，正确和指征适当表现的平均比例为 81%，VR 培训后为 87%（p=0.12），讲座后为 95%（p=0.04）。任何组的手消毒剂消耗量均无明显变化。
结论
由于 VR 技术在医护人员中得到高度认可，因此可以考虑将其作为传统讲座的补充，用于教授手卫生。然而，VR 教学在手消毒剂使用和手卫生依从性方面比传统讲座更有影响的假设无法得到证实。
