Information about the long-term effects of hand hygiene (HH) interventions is needed. We aimed to investigate the change in HH compliance (HHC) of healthcare workers (HCWs) once a data-driven feedback intervention was stopped, and to assess if the COVID-19 pandemic influenced the HH behavior.
We conducted an observational, extension trial in a surgical department between January 2019-December 2020. Doctors (n = 19) and nurses (n = 53) were included and their HHC was measured using an electronic HH monitoring system (EHHMS). We compared the changes in HHC during 3 phases: (1) Intervention (data presentation meetings), (2) Prepandemic follow-up and (3) Follow-up during COVID-19.
The HHC during phase 1 (intervention), phase 2 (prepandemic follow-up) and phase 3 (follow-up during COVID-19) was 58%, 46%, and 34%, respectively. Comparison analyses revealed that the HHC was significantly lower in the prepandemic follow-up period (46% vs 58%, P < .0001) and in the follow-up period during COVID-19 (34% vs 58%, P < .0001) compared with the intervention period (phase 1).
Despite the COVID-19 pandemic, the HHC of the HCWs significantly decreased over time once the data presentation meetings from management stopped. This study demonstrates that HCWs fall back into old HH routines once improvement initiatives are stopped.
需要了解手卫生（HH）干预措施的长期效果。我们旨在调查一旦停止数据驱动的反馈干预，医护人员（HCWs）的 HH 依从性（HHC）的变化，并评估 COVID-19 大流行是否影响 HH 行为。
我们在 2019 年 1 月至 2020 年 12 月期间在一个外科部门进行了一项观察性扩展试验。纳入了医生（n=19）和护士（n=53），并使用电子 HH 监测系统（EHHMS）测量他们的 HHC。我们比较了 3 个阶段的 HHC 变化：（1）干预（数据展示会议），（2）大流行前随访和（3）COVID-19 期间随访。
第 1 阶段（干预）、第 2 阶段（大流行前随访）和第 3 阶段（COVID-19 期间随访）的 HHC 分别为 58%、46%和 34%。对比分析显示，大流行前随访期间（46%与 58%，P<0.0001）和 COVID-19 期间随访期间（34%与 58%，P<0.0001）的 HHC 明显低于干预期（第 1 阶段）。
尽管发生了 COVID-19 大流行，但一旦管理层停止数据展示会议，HCWs 的 HHC 随着时间的推移显著下降。本研究表明，一旦改进措施停止，HCWs 就会恢复旧的 HH 常规。
