Placement of copper objects in intensive care unit (ICU) hospital rooms reduced the number of healthcare-acquired infections (HAIs) in patients by more than half, according to a new study published in the May issue of Infection Control and Hospital Epidemiology, in a special topic issue focused on the role of the environment in infection prevention.
In the United States, HAIs result in 100,000 deaths annually and add an estimated $45 billion to healthcare costs. HAIs often contaminate items within hospital rooms, allowing bacteria to transfer from patient to patient. Common microbes include methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). While several strategies have been developed to decrease HAIs, few have been clinically proven to reduce the spread of these infections. The researchers tested the capability of copper surfaces to reduce environmental contamination of these germs and thereby decrease HAIs in patients. Copper surfaces have an inherent ability to continuously kill environmental microbes on these surfaces.
