Results from a comprehensive multi-site clinical trial demonstrated that the use of antimicrobial copper surfaces in intensive care unit rooms reduced the amount of bacteria in the rooms by 97 percent and resulted in a 41 percent reduction in the hospital acquired infection rate. According to researchers, this study is one of the first to demonstrate the value of a passive infection control intervention, one that does not rely on staff or patients remembering to take action. The results will be presented on Friday, October 21 at the 2011 Annual Meeting of the Infectious Diseases Society of America in Boston.
Objects in hospital patient rooms are a potential breeding ground for bacteria that cause infections. According to Dr. Michael Schmidt, Vice Chairman of Microbiology and Immunology at the Medical University of South Carolina, and a researcher on this study, bacteria on ICU room surfaces are responsible for up to 80 percent of patient infections. The results of this study demonstrate that reducing the amount of bacteria in the patient's environment significantly lowers the risk of infection.
