A comparison of the efficacy of multiple ultraviolet light room decontamination devices in a radiology procedure room.

Objective: To evaluate the efficacy of multiple ultraviolet (UV) light decontamination devices in a radiology procedure room.

Design: Laboratory evaluation.

Methods: We compared the efficacy of 8 UV decontamination devices with a 4-minute UV exposure time in reducing recovery of methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), and Clostridium difficile spores on steel disk carriers placed at 5 sites on a computed tomography patient table.
