BACKGROUND
Waterless alcohol-based hand sanitizers are an increasingly popular method of hand hygiene and help prevent hospital-acquired infection (HAI). Whether hand sanitizer dispensers (HSDs) may themselves harbor pathogens or act as fomites has not been reported.
METHODS
All HSDs in the surgical intensive care unit of an urban teaching hospital were cultured at three sites: The dispenser lever, the rear underside, and the area surrounding the dispensing nozzle.
RESULTS
All HSDs yielded one or more bacterial species, including commensal skin flora and enteric gram-negative bacilli. Colonization was greatest on the lever, where there is direct hand contact.
CONCLUSION
Hand sanitizer dispensers can become contaminated with pathogens that cause HAI and thus are potential fomites.
背景
无水酒精基洗手液是一种越来越受欢迎的手部卫生方法，有助于预防医院获得性感染（HAI）。洗手液分配器（HSD）本身是否可能携带病原体或充当传播媒介尚未报道。
方法
在城市教学医院的外科重症监护病房，对所有 HSD 在三个部位进行培养：分配器杆、背面下方和分配喷嘴周围区域。
结果
所有 HSD 均产生一种或多种细菌，包括共生皮肤菌群和肠道革兰氏阴性杆菌。杆上的定植最多，因为那里有直接的手部接触。
结论
洗手液分配器可能会被引起 HAI 的病原体污染，因此它们是潜在的传播媒介。
