In 1999, an Institute of Medicine study found that as many as 98,000 people die every year as the result of medical error in the U.S., incurring some $17 billion to $29 billion in hospital expenses. In 2009, the Safe Patient Project concluded that the situation may have gotten even worse in the decade that followed. That's a tragedy, which Dr. Andy Wright — a surgeon and one of the core faculty members at the Institute for Simulation and Interprofessional Studies (ISIS), a health-care education program based at the University of Washington — thinks can be helped by playing videogames.
