Scientists devise method to help prevent hospital infections

On any given day, one in 31 hospital patients is diagnosed with an infection that developed as a result of care during their hospital stay, according to the Centers for Disease Control and Prevention. Medical devices such as catheters, stents, heart valves and pacemakers, whose surfaces can become covered with harmful bacterial films, account for about a quarter of such infections. To help prevent such infections, a research team led by Penn State and the University of California, Los Angeles, developed a novel surface treatment for these devices.
