Early efforts addressed wrong-site surgery. Both the "Operate Through Your Initials" program9, introduced in 1993 by the Canadian Orthopaedic Association (COA), and the "Sign Your Site" initiative10,11, introduced in 1998 by the American Academy of Orthopaedic Surgeons (AAOS), predate the 2000 publication of To Err is Human: Building a Safer Health System by the Institute of Medicine12. That report estimated that between 44,000 and 98,000 patient deaths from medical errors occurred in the United States each year. Following that report and the associated media attention, there has been more widespread interest in patient safety and medical errors.
