Don’t just check off the box when it comes to enhanced UVC disinfection

Tru-D_2018 Device_noBkgWhen investing in enhanced UVC disinfection technology, it’s important to make smart purchasing decisions and understand the technology as well as the science behind its effectiveness. Some UVC disinfection methods rely on a fixed cycle time and/or multiple positions around the room which can lead to inefficient disinfection and missed areas. Similarly, some products rely on “data” that has been company-funded or does not have appropriate protocols in place.

Take the guesswork out of disinfection

Germs and pathogens can live anywhere which is why every surface should be a priority when it comes to cleaning and disinfection. Keep in mind that today’s superbugs—such as MRSA, C. diff and CRE—can live on surfaces for long periods of time. In fact, MRSA, VRE, and C. diff can survive for months on surfaces. These and other pathogens need a certain amount of UVC energy to deactivate/neutralize the DNA of the cells.

The Tru-D device’s Sensor360® technology minimizes that risk by calculating the time needed to react to room variables – such as size, geometry, surface reflectivity and the amount and location of equipment in the room. This ensures every pathogen receives the necessary dose needed deactivate its DNA, meaning these superbugs can no longer reproduce.

The science behind the technology

“Real-world” data should include usage in a health care setting without conflicts of interest from the manufacturer. The Tru-D technology was the only device chosen for the first and only randomized clinical trial on UVC disinfection which was funded by the Centers for Disease Control.

The Benefits of Enhanced Terminal Room-Disinfection (BETR-D) study, which was conducted throughout nine hospitals in the Duke Infection Control Outreach Network, showed that the Tru-D technology can reduce the relative risk of colonization and infection caused by epidemiologically important pathogens among patients admitted to the same room by a cumulative 30% in hospital settings with 93% compliance of standard disinfection protocols. Individual hospital results may vary.1

Watch out for UVC companies that bring in a device and hope it works – make sure to partner with a company that will ensure your success. Consider these points when making a choice with it comes to UVC disinfection:

  1. Does the device provide partial or complete room disinfection? Look to technology that not just disinfects a portion of a room but rather ensures thorough room disinfection.
  2. Does the device measure the UVC dose to ensure pathogen inactivation? Research which UVC technologies measure the UVC dose emitted by the device. Not every room is set up the same, and not every superbug requires the same amount of UVC energy for inactivation. A measured dose of UVC will ensure the room receives the precise, necessary dose of UVC disinfection to inactivate any pathogen in the space.
  3. Does the device have sound science behind its technology? Look for research that is conducted by third parties and not funded by the manufacturer. Also, be sure company representatives are not the authors behind the studies.
  4. Does the company provide ongoing support and training or is the device simply dropped off on site? Make sure when considering UVC manufacturers that you investigate ongoing support for the device, training and education for your team as well as reporting and data regarding usage.
