A study, published in the American Journal of Infection Control, examined the effects of a type of ultraviolet (UV) light technology called PurpleSun. It has foldable partitions, which can surround equipment on all sides, and its light hits five surface points. It also uses high levels of UV intensity in 90-second intervals for optimum effect. This technology is designed for use in operating rooms, patient rooms, and other healthcare settings. The study shows that the device can help reduce the risk of infections acquired in the hospital. Researchers used over 3,000 microbiological samples from 100 different surgical cases at three hospitals in the New York area. They found that the technology eliminated most pathogens.
“UV light technology will not replace manual cleaning and disinfection with chemicals, but it has a place in healthcare settings,” says Donna Armellino, lead author of the study and Vice President of Infection Prevention at Northwell Health. “This technology can optimize environmental cleanliness, resulting in decreased pathogens that could potentially cause infection.”
