BACKGROUND Hand hygiene (HH) is a proven low-cost means to curtail the problem of hospital-acquired infection (HAI). However, a low HH compliance rate of 17.1% was found among surgical health workers at Ahmadu Bello University Teaching Hospital (ABUTH) in Zaria, Nigeria. METHODS This was an intervention study conducted utilizing mixed methods to investigate the effectiveness of the World Health Organization (WHO) multimodal strategy to improve the HH compliance rate of doctors at ABUTH Zaria. The study was conducted between June and August 2022 and included delivering a behavioural change HH workshop to doctors followed by data collection in the surgical wards that had received environmental modification through the provision of an alcohol-based hand rub (ABHR), HH posters and nurses for visual and/or verbal reminders. RESULTS The cumulative HH compliance rate was 69% (n=1774) and was significantly different from the baseline HH compliance rate of 17.1% (confidence interval 45.5 to 57.7, p<0.001). Observed HH was highest in the ward with both visual and verbal reminders (78%) and lowest (59%) where neither visual nor verbal reminders were provided (n=444 per ward). All respondents reported motivation to perform HH with the presence of ABHR. CONCLUSIONS The WHO multimodal strategy is good for enhancing HH among health workers in the context of low- and middle-income countries. More research is needed to understand how much of a reduction in HAI is directly associated with efficient HH by health workers.

一项干预研究调查了尼日利亚一家三级医院情境化多模式策略对改善手部卫生的有效性。

背景技术手部卫生(HH)是一种被证明是减少医院获得性感染(HAI)问题的低成本手段。然而，尼日利亚扎里亚艾哈迈杜贝洛大学教学医院 (ABUTH) 的外科医务人员的 HH 合规率较低，仅为 17.1%。方法 这是一项利用混合方法进行的干预研究，旨在调查世界卫生组织 (WHO) 多模式策略提高 ABUTH Zaria 医生 HH 依从率的有效性。该研究于 2022 年 6 月至 8 月期间进行，包括为医生举办行为改变 HH 研讨会，然后在通过提供酒精洗手液 (ABHR)、HH 海报和护士进行环境改造的外科病房收集数据用于视觉和/或口头提醒。结果 累积 HH 合规率为 69% (n=1774)，与基线 HH 合规率为 17.1% 显着不同（置信区间 45.5 至 57.7，p<0.001）。观察到的 HH 在同时提供视觉和口头提醒的病房中最高 (78%)，在既没有提供视觉也没有提供口头提醒的病房中观察到的 HH 最低 (59%)（每个病房 n=444）。所有受访者都报告了在 ABHR 存在的情况下执行 HH 的动机。结论 世卫组织多模式战略有利于提高低收入和中等收入国家卫生工作者的 HH。需要更多的研究来了解 HAI 的减少在多大程度上与卫生工作者的高效 HH 直接相关。
