We conducted a quasi-experimental study and compared hand hygiene behaviors at potential pathogen transmission events among outpatient visitors (according to structured observations a trained enumerator) before and after installation of 12 pedal-operated alcohol gel dispensers with behavioral nudges (signs attached to the dispensers) at a tertiary hospital in southern Thailand during the COVID-19 pandemic. The enumerator observed 243 events during the pre-intervention period and 223 events during the postintervention period. Prevalence of hand hygiene was significantly different between the pre-intervention and post-intervention periods (0 24 events, or 0% 11%, respectively; p-value <0.001). However, 21 of 24 hand hygiene events were of participants who came from outside the observation area, used the dispensers, then left. Nonetheless, the intervention might have helped to increase access to hand hygiene materials and created opportunities for hand hygiene among hospital visitors in general.
在新冠疫情期间，我们在泰国南部一家三级医院进行了一项准实验研究，比较了安装12个带行为助推措施（在洗手液分配器上张贴标识）的脚踏式酒精凝胶分配器前后，门诊访客在潜在病原体传播事件中的手部卫生行为（由经过培训的调查员根据结构化观察）。调查员在干预前阶段观察了243起事件，在干预后阶段观察了223起事件。干预前和干预后阶段的手部卫生普及率存在显著差异（分别为24起事件，即0%；11起事件，即0%；p值<0.001）。然而，24起手部卫生事件中有21起是来自观察区域外的参与者，他们使用了分配器，然后离开。尽管如此，该干预措施可能有助于增加手部卫生用品的可及性，并为一般医院访客创造了手部卫生的机会。
