背景：科学证据表明，手卫生是控制感染的最有效措施之一。为了促进良好的手卫生习惯，世界卫生组织将5月5日定为世界手卫生日（WHHD），国际利益相关者将10月15日定为全球洗手日（GHD）。然而，它对提高公众手部卫生意识的贡献尚不清楚。研究方法：本研究使用Google Trends中“Hand hygiene”的相对搜索量作为替代，评估了2016年至2020年日本、英国、美国和全球范围内WHHD和GHD对公众手部卫生意识的影响。为了确定趋势变化的统计学显著性时间点，我们进行了Joinpoint回归分析。结果如下：从2016年到2019年，全球范围内的相对搜索量以及连接点都在WHHD和GHD周围上升，但2020年在WHHD和GHD周围没有发现连接点。在此期间，在日本、英国和美国没有观察到这种变化。结论：虽然WHHD最初是为了提高医疗机构的手部卫生意识而建立的，但我们的研究结果表明，WHHD和GHD可能没有在国家一级向公众有效宣传手部卫生的重要性。有必要采取额外的政策措施向公众宣传手部卫生，以传达其好处。(c)2021感染控制和流行病学专业人员协会爱思唯尔公司出版All rights reserved.
Background: Scientific evidence suggest that hand hygiene as one of the most effective measures to control infection. To promote good hand hygiene practices, the World Health Organization introduced May 5 as World Hand Hygiene Day (WHHD), and international stakeholders established Global Handwashing Day (GHD) on October 15. However, its contributions to raising public awareness of hand hygiene is unclear. Methods: This study evaluates the impact of the WHHD and GHD on the public awareness of hand hygiene in Japan, the United Kingdom, the United States, and worldwide from 2016 to 2020, using the relative search volume of "Hand hygiene" in Google Trends as a surrogate. To identify a statistically significant timepoint of a trend change, we performed Joinpoint regression analysis. Results: Upticks of the relative search volumes as well as joinpoints were noted worldwide around the WHHD and GHD from 2016 to 2019, but no joinpoints were identified around the WHHD and GHD in 2020. No such changes were observed in Japan, the United Kingdom, and the United States during these periods. Conclusions: While the WHHD was originally established to raise awareness of hand hygiene in healthcare facilities, our result suggests that the WHHD and GHD may not have effectively disseminated the importance of hand hygiene to the general public at a country level. Additional policy measures to advocate hand hygiene to the public are necessary to communicate its benefits. (c) 2021 Association for Professionals in Infection Control and Epidemiology, Inc.
