背景：这项非随机对照观察研究评估了标准的人工化学消毒过程与采用聚焦多矢量紫外线（FMUV）光技术的自动化过程在手术室（OR）终端清洁中的性能。方法：修改围手术期注册护士协会的终末清洁方案，采用自动化FMUV技术，使工作人员在手术期间占据房间。将该改进方案与标准的手工化学清洁和消毒方案进行比较。在终端清洗前后对设备表面进行预采样。采用5点多方抽样法，每道工序共取样165个对象。结果：FMUV平行工艺的活性微生物负荷较基线降低96.5% (P < 0.0001)，优于标准工艺2.5倍以上。标准的终端人工化学消毒过程使采样对象的活性微生物负担比基线减少了38.4% （P < 0.0001）。结论：数据表明，即使在最理想的条件下，在现场临床环境中，标准手动化学消毒的性能也是可变的。相比之下，与平行过程相结合的自动化FMUV处理始终如一地在所有明显清洁的患者护理设备上产生彻底和显著的微生物污染水平降低。(C) 2019年美国感染控制与流行病学专业人员协会Elsevier Inc.出版。版权所有。
Background: This non-randomized comparative observational study evaluated the performance of a standard manual-chemical disinfection process with an automated process employing focused multivector ultraviolet (FMUV) light technology during operating room (OR) terminal cleaning.Methods: An Association of periOperative Registered Nurses terminal cleaning protocol was modified to incorporate the use of automated FMUV technology that allows workers to occupy the room during operation. This modified protocol was compared with a standard manual-chemical cleaning and disinfection protocol. Equipment surfaces were pre-sampled before and after terminal cleaning. A total of 165 objects were sampled in each process using a 5-point multisided sampling method.Results: The parallel process employing FMUV reduced the active microbial burden by 96.5% from baseline (P < .0001), which was over 2.5 times better than the standard process. The standard terminal manual-chemical disinfection process reduced the active microbial burden on sampled objects by 38.4% from baseline (P < .0001).Conclusions: The data demonstrates that the performance of standard manual-chemical disinfection alone is variable in a live clinical setting even under the most ideal conditions. By comparison, automated FMUV treatment incorporated in a parallel process consistently produced thorough and significant reductions of microbial contamination levels on all visibly clean patient care equipment.
