Robot disinfects hospital rooms with a touch of a button

Imagine if you could hit a button and have a patient room disinfected within 10 minutes? Thanks to Mark Stibich, a Texas-based epidemiologist, that concept has become a reality. Stibich co-founded Xenex Healthcare Services and developed a germ-fighting robot that uses UV light to kill viruses, bacteria, and spores.

More than 100 hospitals have purchased or rented the robots, and for good reason. Studies have found that the robot cuts bacterial contamination by a factor of 20 and kills more than 75% of the pathogen C. difficile. Stibich told BusinessWeek [1] that he got the idea to sanitize hospital rooms with UV light several years ago while working in Russia, where he learned that a UV lamp was being used to kill airborne tuberculosis germs.

To use the robot, hospital housekeepers simply wheel it into the room, close the door, and use a remote to operate it. Each robot costs $125,000 or a monthly fee of $3,700. While it seems pricey, the average cost of a hospital-acquired infection can be close to $30,000, making the robot a worthwhile investment. Stibich notes that the robots can be used in staff areas as well as patient rooms, adding to their value in creating a safe hospital environment.
