■很少有研究直接客观地衡量多方面的手卫生教育计划的个人和综合影响。
■为了评估教学视频和手扫描图像对洗手质量的个人和组合即时影响,去污,和知识的提高。
这项整群随机临床试验于2023年6月至7月在香港一所大学的一年级护理学生中进行。该研究使用了意向治疗分析。
■手部卫生教育课程以教学视频为特色,手扫描图像,或者两者兼而有之。
主要结果是干预前后洗手后残留在参与者手上的荧光洗剂残留物的变化。次要结果包括洗手质量和手卫生知识。
■280名学生中的270名(平均[SD]年龄,19[1]岁;182[67.4%]女性)参与试验(96.4%参与率)。参与者被随机分为对照组(66名参与者),手扫描图像组(68名参与者),教学视频组(67名参与者),和手扫描图像与教学视频组(69名参与者)。与对照组相比,所有干预组干预后残留减少幅度更大,虽然没有达到统计学意义(手扫描图像组:3.9[95%CI,2.0-5.8]个百分点;教学视频组:4.8[95%CI,2.9-6.7]个百分点;手扫描图像带教学视频组:3.5[95%CI,1.6-5.4]个百分点;对照组:3.2[95%CI,1.3-5.2]个百分点)。教学视频组显示他们的洗手性能有了显著提高,与对照组相比,正确执行所有7个步骤的参与者百分比更高(22.4%[95%CI,13.1%至31.6%]vs1.5%[-7.9%至10.9%];P<.001)。手部扫描图像显示手腕,指尖,手指网是洗手中最常被忽视的区域。
■在这项手卫生教育项目的整群随机临床试验中,洗手教学视频和手扫描图像并没有提高净化水平。干预组较对照组改善洗手技术,次要结果。

UNASSIGNED: Few studies have directly and objectively measured the individual and combined effects of multifaceted hand hygiene education programs.
UNASSIGNED: To evaluate the individual and combined immediate effects of an instructional video and hand scan images on handwashing quality, decontamination, and knowledge improvement.
UNASSIGNED: This cluster randomized clinical
trial was conducted in June to July 2023 among first-year nursing students at a university in Hong Kong. The
study used an intention-to-treat analysis.
UNASSIGNED: Hand hygiene education sessions featuring an instructional video, hand scan images, or both.
UNASSIGNED: The primary outcome was the change in residue from fluorescent lotion remaining on participants\' hands after handwashing before and after the intervention. The secondary outcomes included handwashing quality and knowledge of hand hygiene.
UNASSIGNED: A total of 270 of 280 students (mean [SD] age, 19 [1] years; 182 [67.4%] female) participated in the
trial (96.4% participation rate). Participants were randomized to a control group (66 participants), hand scan image group (68 participants), instructional video group (67 participants), and hand scan image with instructional video group (69 participants). All intervention groups had greater reductions in residue after the intervention compared with the control group, although none reached statistical significance (hand scan image group: 3.9 [95% CI, 2.0-5.8] percentage points; instructional video group: 4.8 [95% CI, 2.9-6.7] percentage points; hand scan image with instructional video: 3.5 [95% CI, 1.6-5.4] percentage points; control group: 3.2 [95% CI, 1.3-5.2] percentage points). The instructional video group showed a significant improvement in their handwashing performance, with a higher percentage of participants correctly performing all 7 steps compared with the control group (22.4% [95% CI, 13.1% to 31.6%] vs 1.5% [-7.9% to 10.9%]; P < .001). Hand scan images revealed that wrists, fingertips, and finger webs were the most commonly ignored areas in handwashing.
UNASSIGNED: In this cluster randomized clinical
trial of an education program for hand hygiene, a handwashing instructional video and hand scan images did not enhance the level of decontamination. The intervention group had improved handwashing techniques compared with the control group, a secondary outcome.
UNASSIGNED: ClinicalTrials.gov Identifier: NCT05872581.
