CHATTANOOGA, TENN. — Erlanger Health System has taken a giant leap into the future with the addition of a germ-fighting robot that uses ultraviolet light to zap harmful bacteria from equipment and areas throughout the hospital.

Resembling R2D2 from Star Wars, Xenex Disinfection Services’ robot uses pulsed xenon ultraviolet (UV-C) light that is 25,000 times more powerful than sunlight to destroy harmful bacteria, viruses, fungi, and even bacterial spores. Studies show that the Xenex UV disinfectionsystem is consistently 20 times more effective than standard chemical cleaning practices and effective against a variety of the most dangerous superbugs, including Clostridium difficile endospores (C. diff), norovirus, influenza, and staph bacteria like methicillin-resistant staphylococcus aureus, better known as MRSA.

In just five to 10 minutes, the device can disinfect a patient room, patient bathroom or operating room (OR) by pulsing ultraviolet light, which washes over the surfaces where germs reside without leaving a chemical residue. To disinfect a room after standard cleaning procedures are complete, hospital team members wheel the Xenex robot into the room, begin the automated sequence, and then leave the room. For enhanced safety, a sign placed outside the door warns people not to enter, and a motion sensor automatically shuts off the machine if someone should enter.

Erlanger is the first hospital in Chattanooga and the second hospital in Tennessee to use the Xenex robot. 

"We already have a strong infection prevention program. The Xenex technology allows us to be even more proactive in protecting the health of our patients and staff," said Coretha Weaver, Erlanger infection prevention coordinator. "This technology is used in high risk areas, including operating rooms and patient rooms, in conjunction with the extensive cleaning services already provided by our environmental services team."
