Cleaning the places which manual disinfection may not reach
Although cleaning a flat surface is relatively straight-forward using traditional disinfection methods, the picture becomes more complicated when oddly shaped or smaller areas are considered.
Fixings and fixtures such as the side of pipes nearest the wall, door handles, leads, plug sockets and similar can all be overlooked using classic disinfection methods.
Small areas which are touched frequently (such as light switches or door handles) can present a particular challenge when it comes to infection control.
A 2017 study from the American Journal of Infection Control suggests that UVC cleaning could be the answer to this.
The study indicated that there is potential for UVC disinfection to be used on high-traffic, smaller surfaces with irregular contours that may not respond particularly well to standard cleaning, or which may be accidentally missed.
UVC Robots making a significant difference to terminal room cleaning
Once a patient is discharged or leaves the operating theatre, ensuring that a thorough clean is completed before admission of the next patient is an important part of any infection control strategy.
The “terminal clean” needs to be as rigorous as possible. UVC cleaning has been shown to be particularly useful in this respect, resulting in a higher level of cleanliness than when traditional disinfection agents alone were used.
A 2010 study in the Infection Control and Hospital Epidemiology journal showed not only that UVC cleaning made a significant impact on terminal room cleanliness: once the UVC radiation had been applied for fifteen minutes, the levels of bacteria in the surface samples taken had reduced by more than 99.9%.
In addition, the study examined concentrations of C.difficile before and after UVC cleaning. The results were impressive: after 50 minutes of UVC exposure, there was a 99.8% decrease in the numbers of C.difficile bacteria in the environment.
