Effect of UV c for remove C.difficle in hospital

Ultraviolet C light disinfection to clean unoccupied patient rooms significantly reduced C. difficile infections (CDI) in high-risk patients who later occupied those rooms, according to a study published today in Infection Control & Hospital Epidemiology

 “UV light disinfection is a fast, safe, and effective technology to reduce the risk of C. difficile infection associated with the hospital environment. The success of this technology is dependent on Environmental Services employees as a critical partner in our ongoing efforts to eliminate hospital-acquired infections such as C. difficile and to improve patient safety.

The study was conducted in three hematology-oncology units at the Hospital of the University of Pennsylvania during a one-year period. Results showed that adding UV disinfection to typical disinfection protocols reduced the incidence of CDI by 25 percent among new patients in these units, compared to the prior year. At the same time, CDI rates increased 16 percent in the non-study units during this period. The team found that using the ultraviolet robot after a room cleaning by members of the Environmental Services team not only reduced the number of infections, but did so without adversely impacting room turnaround time. According to this study, room cleaning took only five minutes longer on average compared to non-study units.

CDI is one of the most common healthcare-acquired infections in the United States and is associated with serious complications. It is resistant to many surface disinfectants and can persist on surfaces, making it an ongoing risk for transmission to patients.

While the UV disinfection device proved to be effective at reducing CDI incidence, it showed no effect on other healthcare-associated infections, such as methicillin-resistant Staphylococcus aureus (MRSA).
