Healthcare associated infections (also referred to as HAIs 
      or hospital acquired infections) are the fourth leading cause of death 
      in the United States, costing more than $30 billion each year. Evidence 
      continues to mount that hospital cleanliness plays a role in the spread 
      of HAIs, which are caused by deadly pathogens such as C. diff, 
      MRSA, VRE and Acinetobacter. Hospital cleaning teams are not able 
      to disinfect all the surfaces in patient rooms in the allotted time, 
      with research showing that more than half of the surfaces remain 
      untouched. Additionally, deadly "superbugs" such as C. diff are 
      showing resistance to cleaning fluids, making them even more difficult 
      to remove and eliminate.

      Healthcare Services recently participated in a study conducted at 
      The University of Texas MD Anderson Cancer Center to evaluate the 
      efficacy of its pulsed 
      xenon UV light disinfection system versus bleach in a hospital 
      setting. Shashank Ghantoji, M.D., M.P.H., a postdoctoral fellow, 
      presented the poster, "Comparison of Pulsed Xenon UV to Bleach for the 
      Decontamination of C. difficile from Surfaces in the Patient 
      Environment" at the recent ICAAC conference in San Francisco. Sponsored 
      by the American Society for Microbiology, ICAAC showcases the 
      latest-breaking science and lectures from top researchers from around 
      the world.
    
    
      "The study showed a 95 percent reduction in C. diff when the 
      rooms were cleaned with the device(s)," said Roy 
      F. Chemaly, M.D., M.P.H., associate professor in MD Anderson's Department 
      of Infectious Diseases, Infection Control and Employee Health.
    
    
      In many hospitals, Clostridium difficile (C. diff) is a 
      primary pathogen of concern. Many patients, especially those on 
      antibiotics, are susceptible to C. diff, which can live for up to 
      five months on surfaces in the hospital. A person with C. diff 
      contaminates his or her hospital room and bathroom, leaving C. diff 
      spores on the walls, handles and other high-touch surfaces.
    
    
      "The results presented in this study are exciting - and consistent with 
      what we've seen from our customers around the U.S., some of whom have 
      seen drops in C. diff rates after using our pulsed xenon 
      technology," said Dr. Mark 
      Stibich, Chief Scientific Officer for Xenex. "Being able to 
      demonstrate that our device gets a room cleaner than bleach is a 
      milestone for Xenex - especially as hospitals are looking for 
      environmentally friendly ways to get their patient environments clean."
    
    
      The current standard for C. diff surface decontamination in the 
      healthcare setting is a bleach solution, which may damage hospital 
      materials and create a toxic environment for hospital workers. Xenex 
      Healthcare Services' pulsed xenon UV (PX-UV) light room disinfection 
      system has been repeatedly proven effective against C. diff in 
      the laboratory and in patient outcome results at hospitals utilizing 
      Xenex devices. The purpose of this study was to determine if Xenex's 
      pulsed xenon UV light technology is equivalent to bleach for the 
      decontamination of surfaces in C. diff isolation rooms at 
      discharge.
    
    
      High-touch surfaces in rooms previously occupied by C. diff-infected 
      patients were sampled after discharge but before and after cleaning 
      using bleach or non-bleach cleaning followed by 15 minutes of PX-UV 
      treatment. A total of 298 samples were collected using a moistened wipe 
      specifically designed for the removal of spores and the numbers of 
      colony forming units (CFU) of C. diff before and after each 
      decontamination method were compared. Recovered C. diff decreased 
      70 percent after the use of bleach while recovered C. diff 
      decreased a dramatic 95 percent after the use of PX-UV. In short, rooms 
      treated with Xenex PX-UV had six times fewer CFU of C. diff 
      recovered than the rooms treated with bleach.
