A World Health Organization (WHO) guideline-based multimodal hand hygiene (HH) initiative was introduced hospital-wide to a nonteaching Japanese hospital for 5 years. The objective of this study was to assess the effect of this initiative in terms of changes in alcohol-based hand rub (ABHR) consumption and the Hand Hygiene Self-Assessment Framework (HHSAF) score. The consumption of monthly hospital-wide ABHR was calculated in L per 1000 patient days (PDs). The change in ABHR consumption was analysed by an interrupted time series analysis with a pre-implementation period of 36 months and an implementation period of 60 months. The correlation between annual ABHR consumption and the HHSAF score was estimated using Pearson’s correlation coefficients. The annual ABHR consumption was 4.0 (L/1000 PDs) to 4.4 in the pre-implementation period and 10.4 to 34.4 in the implementation period. The HHSAF score was 117.5 (out of 500) in the pre-implementation period and 267.5 to 445 in the implementation period. A statistically significant increase in the monthly ABHR consumption (change in slope: + 0.479 L/1000 PDs, p < 0.01) was observed with the implementation of the initiative. Annual ABHR consumption was strongly correlated with the annual HHSAF score (r = 0.971, p < 0.01). A 5-year WHO-based HH initiative significantly increased ABHR consumption. Our study suggested that the HHSAF assessment can be a good process measure to improve HH in a single facility, as ABHR consumption increased with the HHSAF score.

基于WHO多模式手部卫生改善策略的5年手部卫生计划的效果：时间序列研究中断。

一项基于世界卫生组织（WHO）指南的多模式手部卫生（HH）计划在全院范围内引入了一家无教学的日本医院，历时5年。这项研究的目的是评估基于酒精的手揉搓（ABHR）消耗量和手卫生自我评估框架（HHSAF）得分变化方面的这一举措的效果。每月医院范围内ABHR的消耗量以每1000患者日（PDs）的L来计算。通过中断时间序列分析来分析ABHR消耗量的变化，实施时间为36个月，实施时间为60个月。使用皮尔森相关系数估算年度ABHR消耗量与HHSAF评分之间的相关性。在实施前的期间，ABHR的年度消费为4.0（L / 1000 PD），至4.4，为10。实施期间为4至34.4。HHSAF评分在实施前为117.5分（满分500分），在实施期间为267.5分至445分。随着该计划的实施，观察到的每月ABHR消耗量有统计上的显着增加（斜率变化：+ 0.479 L / 1000 PD，p <0.01）。每年的ABHR消耗量与每年的HHSAF评分高度相关（r = 0.971，p <0.01）。一项基于WHO的为期5年的HH计划显着增加了ABHR消耗量。我们的研究表明，由于ABHR消耗随HHSAF分数的增加而增加，因此HHSAF评估可以是改善单个机构中HH的良好过程方法。随着该计划的实施，观察到的每月ABHR消耗量有统计上的显着增加（斜率变化：+ 0.479 L / 1000 PD，p <0.01）。每年的ABHR消耗量与每年的HHSAF评分高度相关（r = 0.971，p <0.01）。一项基于WHO的为期5年的HH计划显着增加了ABHR消耗量。我们的研究表明，由于ABHR消耗随HHSAF分数的增加而增加，因此HHSAF评估可以是改善单个机构中HH的良好过程方法。随着该计划的实施，观察到的每月ABHR消耗量有统计上的显着增加（斜率变化：+ 0.479 L / 1000 PD，p <0.01）。每年的ABHR消耗量与每年的HHSAF评分高度相关（r = 0.971，p <0.01）。一项基于WHO的为期5年的HH计划显着增加了ABHR消耗量。我们的研究表明，由于ABHR消耗随HHSAF分数的增加而增加，因此HHSAF评估可以成为改善单个机构中HH的有效过程。
