When emergency medical services (EMS) providers respond to the scene of an injury, they must decide where to transport the injured patients for further evaluation and treatment. This is done through a process known as “field triage”, whereby a patient’s injuries are matched to the most appropriate hospital. In 2005–2006 the National Expert Panel on Field Triage, convened by the Centers for Disease Control and Prevention and the National Highway Traffic Safety Administration, revised the 1999 American College of Surgeons Committee on Trauma Field Triage Decision Scheme. This revision, the 2006 Field Triage Decision Scheme, was published in 2006.
