The Power of One Placement

This is the first of a blog series by Alice Brewer, Clinical Affairs Director for Tru-D SmartUVC.

If your facility is considering adding UVC disinfection to your cleaning protocols, the product should help complement your existing process and not make it more difficult.

Just like every hospital room is different, not all UVC disinfection devices are created equally. Tru-D is the only device of its kind with patented Sensor360 technology allowing it to measure the amount, or dose, of UVC reflected back to the robot to ensure complete room disinfection.

What does that really mean, though? With most devices, disinfection is limited by distance – how close the device is to the surface being disinfected. However, with Tru-D, it doesn’t matter how far away the surface is or how many objects are in the room. Tru-D takes room variables into account and dispenses UVC until all sensors have received an adequate, reflected dose.  This means that all surfaces in the room are thoroughly disinfected with only one placement. There’s no need to move Tru-D from location to location or tether the operator to the machine.

Tru-D’s technology has been shown by independent research to be effective. Nerandzic et al. conducted one of the first studies to evaluate Tru-D’s ability to disinfect a room from one position. They found that by placing Tru-D in the approximate center of the room, they were able to achieve at least a 2 log10 reduction of MRSA, C. difficile and VRE in direct and indirect line of site.

One placement UVC disinfection has been shown by several other independent studies to be effective as well– you can visit our Third-Party Validations page here.

In addition to ensuring complete room disinfection, the ability to disinfect a room from one position can significantly impact the productivity of environmental services (ES) staff. Tru-D eliminates the need for someone to be available to move the device to a new location every few minutes. ES staff can complete other tasks while Tru-D finishes disinfecting a room. That improves throughput as well – ES can get other rooms ready for patients while Tru-D runs in an isolation room.

“Last year, our hospital had 81 cases of hospital-acquired C. diff. We’re on pace to have about one-third fewer hospital-acquired infections of all kinds this year, a decrease I attribute to the whole-room disinfection technologies we’ve added to our manual cleaning.” – Randy Barnes, St. Charles Bend

The first-ever randomized clinical trial on UVC disinfection, the Benefits of Enhanced Terminal Room-Disinfection (BETR-Disinfection) study, showed that enhanced terminal room disinfection strategies using Tru-D decreased the relative risk of colonization and infection of target MDROs among patients admitted to the same room by a cumulative 30% in a hospital setting with 93% compliance of standard disinfection protocols. Individual hospital results may vary.
