The authors developed a video-centred teaching program based on social learning principles to demonstrate hand-washing technique. A comparison was made between families who viewed the video and families who were taught the same techniques with the aid of an illustrated poster in terms of compliance and improvement in hand-washing skills.
Nosocomial infections are a significant cause of morbidity and mortality in paediatric intensive care unit patients. Hand hygiene is considered the most important preventive action against hospital-acquired infections. A number of studies have shown that increased compliance with hand-washing guidelines for health-care workers leads to decreases in nosocomial infection rates. Furthermore, recommendations have been made to ensure that parents who visit their children in intensive care units wash their hands first.
Quasi-experimental time series. Compliance and accuracy measurements were collected during one to five visits following the initial teaching intervention.
A total of 123 families, who visited paediatric intensive care units, were recruited and assigned to two groups - one experimental (61 families) and the other a comparison group (62). Participants in the comparison group were taught hand-washing skills using simple illustrations. A 20-item hand-washing checklist was used to examine hand-washing compliance and accuracy.
No significant differences were noted in terms of demographics between the two groups. Results from a general estimated equation analysis showed that families in the experimental group had higher compliance and accuracy scores at statistically significant levels.
The video-based teaching program was effective in increasing compliance and accuracy with a hand-washing policy among families with children in intensive care units.
The education program is a simple, low-cost, low technology intervention for substantially reducing the incidence of nosocomial infection.
作者基于社会学习原则开发了一个以视频为中心的教学项目，以演示洗手技术。比较观看视频的家庭和借助图文海报学习相同技术的家庭在洗手依从性和技能提升方面的情况。
医院感染是儿科重症监护病房患者发病和死亡的重要原因。手部卫生被认为是预防医院获得性感染最重要的预防措施。多项研究表明，医护人员洗手指南的依从性提高会导致医院感染率下降。此外，还建议确保在重症监护病房探视孩子的家长先洗手。
准实验时间序列。在初始教学干预后的一至五次探视期间收集依从性和准确性测量数据。
共招募了123名探视儿科重症监护病房的家庭，并将其分为两组——一组为实验组（61个家庭），另一组为对照组（62个家庭）。对照组的参与者通过简单图示学习洗手技能。使用一份包含20项内容的洗手检查表来检查洗手的依从性和准确性。
两组在人口统计学方面未发现显著差异。一般估计方程分析结果显示，实验组家庭在统计学显著水平上具有更高的依从性和准确性得分。
基于视频的教学项目对于提高重症监护病房患儿家庭对洗手政策的依从性和准确性是有效的。
该教育项目是一种简单、低成本、低技术含量的干预措施，可大幅降低医院感染的发生率。
