UV Angel Disinfection System Shows Pathogen Reduction on Hospital Computer Keyboards

American Journal of Infection Control (AJIC) has released an evaluation of the UV Angel disinfection system conducted by Dr. Curtis Donskey and his team at the Louis Stokes Cleveland VA Medical Center, Cleveland, Ohio. The study validates the efficacy and safety of low dose UV-C while disinfecting computer keyboards within patient rooms.


Livonia, MI., January 21, 2016 – Healthcare Information Technology (HIT) implementation has introduced many new devices and high-touch surfaces to the patient bedside. Contaminated computer keyboards and healthcare equipment are a potential source for transmission of healthcare–associated pathogens and respiratory viruses in healthcare facilities. A known concern, keyboards and many other high-touch devices are frequently contaminated with bacterial pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile (C. diff) spores.

UV Angel reduces pathogens like methicillin-resistant Staphylococcus aureus, carbapenem-resistant Escherichia coli, and C. diff spores within 1 cycle.

Dr. Donskey and his team observed that UV Angel reduces pathogens like methicillin-resistant Staphylococcus aureus, carbapenem-resistant Escherichia coli, and C. diff spores within 1 cycle. Donskey’s team also reports that the UV Angel system can potentially complete >100 cycles each day with no operator required. Daily disinfection of high-touch surfaces have been proven to be useful in the reduction of hand contamination by healthcare personnel providing care for their patients.

Some chemical disinfectants such as chlorhexidine lack sporicidal activity while others like sodium hypochlorite (bleach) damage costly medical equipment. UV Angel believes there is a need for new approaches that eliminate pathogens and also reduces the disinfection burden placed on caregivers. Ultraviolet-C (UV-C) is effective in killing a wide range of viral and bacterial pathogens, including C. diff spores. High-intensity UV-C devices are commonly used for patient room disinfection and cannot be used when people are present. The UV Angel disinfection system offers a different solution by incorporating small (17.8 cm tall × 30.5 cm wide) low-intensity UV-C lamps to multiple high-touch equipment within the patient room. All UV Angel devices require no technician to operate due to the use of software and PIR sensors that activate and deactivate equipment disinfection around the clock. Typical technology and equipment UV Angel mounts onto are:

  • Keyboards/Mice/Bar code Scanners
  • Mobile Computer Workstations
  • Touchscreens
  • Vital Sign Monitors
  • Dialysis Machines
  • Ventilators
  • IV and Infusion Pumps

While Donskey and his team report that the UV Angel device significantly reduces total bacterial counts they also evaluated its safety. Their findings suggest that because the device is intended to be used while personnel are in the same room, the potential for exposure of personnel to UV-C was a concern. However using UV-C indicator strips and a radiometric sensor, they did not find evidence that UV-C penetrated outside the safe area. In addition to the low-intensity UV-C the UV Angel system consistently aborted its cycles when movement into the area of the keyboard was detected.

This study was funded by a merit review grant from the U.S. Department of Veterans Affairs to Dr. Donskey.
