BACKGROUND
Institutional hand hygiene (HH) behavior is difficult to monitor and improve consistently, especially over long periods. This study aimed to investigate the long-term effects of HH promotion activities.
METHOD
We launched the HH promotion team in 2010 and conducted interventions including goal setting, observation and feedback, education, reward incentives, and accountability. Optimal HH compliance rates were calculated based on adherence to all 6-step HH technique and appropriate time recommended by the World Health Organization. HH and optimal HH compliance were calculated over 12 years. Poisson regression analysis was used to determine the trend in HH compliance according to year.
RESULTS
In 2010, HH and optimal HH compliance were 59.7% and 15.6%, respectively. HH compliance increased by 83.9% in 2013 and remained over 75%. HH compliance increased significantly, with a relative risk (RR) of 1.014 (95% CI 1.002-1.025, P = .018). Optimal HH compliance increased by 67.8% in 2013 and remained over 60%, except in 2016 (58.8%) and 2019 (59.8%). Optimal HH compliance increased with RR 1.033 (95% CI 0.991-1.076, P = .123).
DISCUSSION
HH and optimal HH compliance increased significantly over the 12 years when subgroup analysis was performed by job category.
CONCLUSIONS
HH promotion team activities improved and maintained optimal HH compliance among HCWs.
背景
机构手卫生（HH）行为难以持续监测和改善，尤其是长期如此。本研究旨在调查 HH 促进活动的长期效果。
方法
我们于 2010 年成立 HH 促进小组，实施包括设定目标、观察和反馈、教育、奖励激励和责任制等干预措施。根据世界卫生组织（WHO）推荐的所有 6 步 HH 技术和适当时间，计算 HH 最佳依从率。在 12 年内计算 HH 和最佳 HH 依从率。采用泊松回归分析确定按年份 HH 依从率的趋势。
结果
2010 年，HH 和最佳 HH 依从率分别为 59.7%和 15.6%。2013 年 HH 依从率增加了 83.9%，并保持在 75%以上。HH 依从率显著增加，相对风险（RR）为 1.014（95%置信区间 1.002-1.025，P =.018）。最佳 HH 依从率在 2013 年增加了 67.8%，并保持在 60%以上，除 2016 年（58.8%）和 2019 年（59.8%）。最佳 HH 依从率随 RR 增加 1.033（95%置信区间 0.991-1.076，P =.123）。
讨论
按职业类别进行亚组分析时，12 年来 HH 和最佳 HH 依从率显著增加。
结论
HH 促进小组活动提高并维持了 HCW 最佳 HH 依从率。
