A recent study showed hand-hygiene compliance at one hospital doubled after flashing red lights were placed on hand-sanitizer dispensers, according to an article on the Becker's Hospital Review website.
The study was published in the American Journal of Infection Control.
The red-light intervention increased compliance to 23.5 percent in cold weather and to 27.1 percent during warm weather, the researchers found. Overall, the pooled compliance rate increased to 25.3 percent, the article said.
