Abstract
Background:A World Health Organization (WHO) guideline-based multimodal hand hygiene (HH) initiative consisting of the 5 Components, the 5 Steps, and the HH Self-Assessment Framework (HHSAF) 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 HHSAF score.Methods:The consumption of monthly hospital-wide ABHR was calculated as ml per patient day (PD). The change in ABHR consumption was analysed by an interrupted time series analysis, with a preintervention period of 36 months and an intervention period of 60 months. The correlation between annual ABHR consumption and the HHSAF score was estimated using Pearson’s correlation coefficients.Results:A statistically significant increase was found in the monthly ABHR consumption (change in slope: + 0.479 ml/PD, p < 0.01). Annual ABHR consumption was strongly correlated with the annual HHSAF score (r = 0.971, p < 0.01).Conclusions:A 5-year, 5-step, WHO-based HH initiative significantly increased ABHR consumption. Our study suggested that the HHSAF score can be a good process measure to improve HH in a single facility, as ABHR consumption increased with the HHSAF score.
