“One surgeon may wash their hands five minutes with one agent, another may wash for one minute with another agent,” Dr. Parvizi explains, “so that’s why we had the world’s experts sit here and decide which of those practices were the right thing to do for the patients.”

More than 300 people agreed on the document that contains 246 different items.  The guidelines are already being sent around the world to become the standard of care for avoiding infection in joint replacement surgeries.
