Abstract

Background: There is not yet a consensus regarding the in-use effectiveness of ultraviolet irradiation (UV-C) as a supplementary tool for terminal room disinfection.

Aims and objectives: To summarize and evaluate literature detailing the germicidal effectiveness of UV-C disinfection on high-touch surfaces in the patient environment.

Methods: A literature search was carried out utilizing PRISMA guidelines. Studies were included if intervention included UV-C after standard room disinfection in hospital rooms evaluated microbiologically by surface type.

Findings/results: Twelve records met our criteria for inclusion. Studies predominantly focused on terminal disinfection of patient rooms, including five reports carried out in isolation rooms and three studies including operating room (OR) surfaces. Bedrails, remote controls, phones, tray tables, assist rails, floors, and toilets were the most commonly reported surfaces. Across study designs, surfaces, and room types, flat surfaces tended to showcase UV-C effectiveness best, particularly isolation room floors. In contrast, handheld surfaces (i.e., bed controls and assist bars) tended to show reduced efficacies (81-93%). In the OR, complex surfaces similarly demonstrated reduced UV-C effectiveness. Bathroom surfaces demonstrated 83% UV-C effectiveness overall, with surface characteristics uniquely impacted depending on the room type. Isolation room studies tended to include effectiveness comparison with standard treatment, reporting UV-C superiority most of the time.

Discussion: This review highlights the enhanced effectiveness of UV-C surface disinfection over standard protocols across various study designs and surfaces. However, surface and room characteristics do appear to play a role in the level of bacterial reduction.

对患者直接接触的高接触表面进行紫外线消毒的杀菌效果进行系统回顾。
背景:关于紫外线照射(UV-C)作为终端病房消毒辅助工具的使用效果,目前尚未达成共识:目的:总结并评估有关紫外线-C 消毒对患者环境中高接触表面的杀菌效果的文献:方法:根据 PRISMA 指南进行文献检索。根据表面类型对病房进行微生物学评估后,如果干预措施包括紫外线-C消毒,则纳入研究:有 12 条记录符合我们的纳入标准。研究主要集中在病房的终端消毒,其中五项报告在隔离室进行,三项研究包括手术室(OR)表面。床栏、遥控器、电话、托盘桌、辅助扶手、地板和马桶是最常报告的表面。在各种研究设计、表面和房间类型中,平整的表面往往最能体现紫外线-C 的效果,尤其是隔离室的地板。相比之下,手持式表面(即床控制器和辅助杆)的紫外线照射效率往往较低(81-93%)。在手术室,复杂的表面同样显示出紫外线-C 效能降低。浴室表面的紫外线-C 有效率总体为 83%,根据房间类型的不同,表面特征也会受到独特的影响。隔离室的研究往往包括与标准治疗的效果比较,大多数情况下都报告紫外线-C 的优越性:讨论:本综述强调了在各种研究设计和表面中,紫外线-C 表面消毒比标准方案更有效。不过,表面和房间的特性似乎对细菌减少的程度有影响。
