Reduction of microbial contamination of the hospital environment is a challenge, yet has potential impacts on infection prevention efforts. Fumigation and UV light devices for environmental cleaning have expanded into the health care setting with the goal of decontamination of difficult to clean or overlooked surfaces. In an era of increased scrutiny of hospital-acquired infections, increasingly, health care centers are adopting these "touchless" cleaning techniques as adjuncts to traditional manual cleaning. The evidence for improved clinical outcomes is lacking; yet, the experience with these devices continues to accumulate in the literature. We review the recently published data related to the use of hydrogen peroxide and UV light-based decontamination systems for cleaning of hospital rooms. Touchless cleaning technologies may provide an incremental benefit to standard practices by limiting cross-transmission of pathogens via environmental surfaces, though evidence of prevention of infections remains limited.
减少医院环境中的微生物污染是一项挑战,但对感染预防工作具有潜在影响。熏蒸和紫外线设备已扩展到医疗保健环境中,目的是对难以清洁或被忽视的表面进行消毒。在对医院获得性感染进行越来越严格审查的时代,越来越多的医疗机构正在采用这些“无接触”清洁技术作为传统手动清洁的辅助手段。缺乏改善临床结果的证据;然而,这些设备的经验继续在文献中积累。我们回顾了最近发表的与使用过氧化氢和基于紫外线的去污系统清洁医院病房相关的数据。无接触清洁技术通过限制通过环境表面传播病原体,可能会对标准操作提供额外的益处,但预防感染的证据仍然有限。
