原文标题：Hospital surface disinfection using ultraviolet germicidal irradiation technology: A review

译文标题：紫外线杀菌照射技术在医院表面消毒中的应用研究进展

原文摘要：

Ultraviolet germicidal irradiation (UVGI) technologies have emerged as a promising alternative to biocides as a means of surface disinfection in hospitals and other healthcare settings. This paper reviews the methods used by researchers and clinicians in deploying and evaluating the efficacy of UVGI technology. The type of UVGI technology used, the clinical setting where the device was deployed, and the methods of environmental testing that the researchers followed are investigated. The findings suggest that clinical UVGI deployments have been growing steadily since 2010 and have increased dramatically since the start of the COVID-19 pandemic. Hardware platforms and operating procedures vary considerably between studies. Most studies measure efficacy of the technology based on the objective measurement of bacterial bioburden reduction; however, studies conducted over longer durations have examined the impact of UVGI on the reduction of healthcare associated infections (HCAIs). Future trends include increased automation and the use of UVGI technologies that are safer for use around people. Although existing evidence seems to support the efficacy of UVGI as a tool capable of reducing HCAIs, more research is needed to measure the magnitude of these effects and to establish recommended best practices.

译文摘要：

紫外线杀菌照射(UVGI)技术已成为一种很有前途的生物杀菌剂替代品，可作为医院和其他医疗机构的表面消毒手段。本文综述了研究人员和临床医生在部署和评估UVGI技术的有效性时使用的方法。使用的UVGI技术的类型，设备部署的临床环境，以及研究人员遵循的环境测试方法进行了调查。研究结果表明，自2010年以来，临床UVGI部署一直在稳步增长，自COVID-19大流行开始以来大幅增加。硬件平台和操作程序在不同的研究中差异很大。大多数研究基于对细菌生物负荷减少的客观测量来衡量该技术的有效性;然而，在较长时间内进行的研究检查了UVGI对减少医疗相关感染(HCAIs)的影响。未来的趋势包括提高自动化程度和使用更安全的UVGI技术。尽管现有证据似乎支持UVGI作为一种能够减少HCAIs的工具的有效性，但还需要更多的研究来衡量这些影响的程度，并建立推荐的最佳实践。
