“…However, the marketing of a variety of UV devices with different designs, capabilities, and costs has made selection of such devices problematic for healthcare institutions. 7,16 Determining the effectiveness of devices is complicated by lack of standard methods for testing UV-C devices, limited published data on the doses of UV delivered to various surfaces in patient rooms, and conflicting data on the UV dose (fluence) necessary to achieve desired reductions of various healthcare pathogens, including C. difficile. 12,[17][18][19][20][21][22][23][24] Healthcare personnel would benefit from a basic understanding of the characteristics of UV-C, the availability of more evidence on the UV-C doses delivered to surfaces in patient rooms, and knowledge of the UV-C doses required to reduce specific healthcare pathogens.…”

Ongoing challenges in maintaining optimum manual cleaning and disinfection of hospital rooms have created increased interest in “no-touch” decontamination technologies including the use of ultraviolet light (UV). Trials have shown that some UV devices can decrease surface contamination and reduce healthcare-associated infections. Despite substantial marketing of these devices for use in healthcare settings, few data are available regarding the doses of UV-C necessary to yield desired reductions in healthcare pathogens and the ability of mobile devices to deliver adequate doses to various surfaces in patient rooms. This review summarizes the physical aspects of UV that affect the doses delivered to surfaces, the UV-C doses needed to yield 3 log10 reductions of several important healthcare-associated pathogens, the doses of UV-C that can be achieved in various locations in patient rooms using mobile UV-C devices, and methods for measuring UV doses delivered to surfaces.

“…The key elements of a successful UV program are not well defined; they likely include deliberate program design and clinical staff acceptance. 14,19 By design, our rooms are released for admission following cleaning; no hold is placed for UV disinfection. We chose to avoid patient flow delays, and we gave staff a sense of control over room availability, accepting that we likely missed opportunities due to patient need.…”

Objective:To prevent environmental transmission of pathogens, hospital rooms housing patients on transmission-based precautions are cleaned extensively and disinfected with ultraviolet (UV) light. To do so consistently requires time and coordination, and these procedures must avoid patient flow delays and associated safety risks. We sought to improve room turnover efficiency to allow for UV disinfection.Design:A 60-day quality improvement and implementation project.Setting:A quaternary academic pediatric referral facility.Interventions:A multidisciplinary healthcare team participated in a 60-day before-and-after trial that followed the Toyota Production System Lean methodology. We used value-stream mapping and manual time studies to identify areas for improvement. Areas addressed included room breakdown, room cleaning, and wait time between cleaning and disinfection. Room turnover was measured as the time in minutes from a discharged patient exiting an isolation room to UV disinfection completion. Impact was measured using postintervention manual time studies.Results:Median room turnover decreased from 130 minutes (range, 93–294 minutes) to 65 minutes (range, 48–95 minutes; P < .0001). Other outcomes included decreased median time between room breakdown to cleaning start time (from 10 to 3 minutes; P = .004), room cleaning complete to UV disinfection start (from 36 to 8 minutes; P < .0001), and the duration of room cleaning and curtain changing (from 57 to 37 minutes; P < .0001).Conclusion:We decreased room turnover time by half in 60 days by decreasing times between and during routine tasks. Utilizing Lean methodology and manual time study can help teams understand and improve hospital processes and systems.

“…Several papers described the use of UVGI in clinical settings without describing the underlying technology that was used [21][22][23][24][25][26] and were not included in Tables 1 or 2. While [27] utilised a UV robot, the type of technology is unclear and was also omitted from Table 1.…”

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.
