We aimed to investigate whether the provision of water, sanitation, and hand hygiene (WASH) interventions were associated with changes in hand hygiene compliance and perceptions of healthcare workers towards infection control.
The study was conducted from June 2017 through February 2018 among healthcare workers in two Northern districts of Ghana. Using a pretest-posttest design, we performed hand hygiene observations and perception surveys at baseline (before the start of WASH interventions) and post-intervention (midline and endline). We assessed adherence to hand hygiene practice using the WHO direct observation tool. The perception study was conducted using the WHO perception survey for healthcare workers. Study outcomes were compared between baseline, midline and endline assessments.
The hand hygiene compliance significantly improved from 28.8% at baseline through 51.7% at midline (n = 726/1404; 95% CI: 49.1-54.2%) to 67.9% at endline (n = 1000/1471; 95% CI: 65.6-70.3%). The highest increase in compliance was to the WHO hand hygiene moment 5 after touching patients surrounding (relative increase, 205%; relative rate, 3.05; 95% CI: 2.23-4.04; p < 0.0001). Post-intervention, the top three policies deemed most effective at improving hand hygiene practice were: provision of water source (rated mean score, n = 6.1 ± 1.4), participation in educational activities (rated mean score 6.0 ± 1.5); and hand hygiene promotional campaign (6.0 ± 1.3).
Hand hygiene compliance significantly improved post-intervention. Sustaining good hand hygiene practices in low resource settings should include education, the provision of essential supplies, and regular hand hygiene audits and feedback.
我们旨在调查提供水、环境卫生和手部卫生(WASH)干预措施是否与手部卫生依从性的变化以及医护人员对感染控制的认知有关。
该研究于2017年6月至2018年2月在加纳北部两个地区的医护人员中进行。采用前测-后测设计,我们在基线(WASH干预开始前)和干预后(中期和末期)进行了手部卫生观察和认知调查。我们使用世界卫生组织直接观察工具评估手部卫生实践的依从性。认知研究使用世界卫生组织医护人员认知调查问卷进行。比较了基线、中期和末期评估的研究结果。
手部卫生依从性从基线时的28.8%显著提高到中期的51.7%(n = 726/1404;95%置信区间:49.1-54.2%),末期达到67.9%(n = 1000/1471;95%置信区间:65.6-70.3%)。依从性提高最多的是世界卫生组织手部卫生时刻5(接触患者周围环境后)(相对增幅,205%;相对率,3.05;95%置信区间:2.23-4.04;p < 0.0001)。干预后,被认为对改善手部卫生实践最有效的前三项政策是:提供水源(平均评分,n = 6.1 ± 1.4)、参与教育活动(平均评分6.0 ± 1.5);以及手部卫生宣传活动(6.0 ± 1.3)。
干预后手部卫生依从性显著提高。在资源匮乏地区维持良好的手部卫生实践应包括教育、提供基本用品以及定期进行手部卫生审核和反馈。
