OBJECTIVE
To compare the effects of the simplified 5-step and the conventional 7-Step hand hygiene programme in a cluster randomized controlled trial among students with intellectual disabilities.
METHOD
A total of 472 Chinese students with intellectual disabilities were randomized to either simplified 5-step or conventional 7-step hand hygiene programme. Assessments included handwashing technique, cleanliness and sick leave days.
RESULTS
Handwashing technique scores (g = 0.25, 95% CI [0.18, 0.32]) and hand cleanliness scores (g = 0.33, 95% CI [0.26, 0.4]) in intervention group were significantly higher than those scores in control group at 6th month post-intervention although there were significant increases in the scores within both groups. The mean number of sick leave days decreased between baseline and 10 month in both groups according to descriptive statistics.
CONCLUSIONS
It is feasible and effective to adopt the simplified 5-step intervention as a standardized handwashing technique for the population group with intellectual disabilities.
目的
在一项智障学生的集群随机对照试验中，比较简化的 5 步与传统的 7 步手卫生方案的效果。
方法
共 472 名智障中国学生被随机分配到简化 5 步或传统 7 步手卫生方案组。评估包括洗手技术、清洁度和病假天数。
结果
干预组在第 6 个月的手卫生技术评分（g=0.25，95%置信区间[0.18，0.32]）和手部清洁度评分（g=0.33，95%置信区间[0.26，0.4]）明显高于对照组，尽管两组内的评分都有显著提高。根据描述性统计，两组的病假天数均在基线和 10 个月之间有所减少。
结论
采用简化的 5 步干预作为智障人群的标准化洗手技术是可行且有效的。
