A new patient outcome based triage methodology has been developed by Dr. Bill Sacco, one of the world authorities on trauma management, which puts the patients’ survival outcome as the highest priority within the resources currently available in your EMS and Trauma System. The Sacco Triage Method (STM) utilizes sound science, is evidence based from beginning to end, and is used everyday on every trauma patient so the EMS provider obtains the mastery and skills required when they are called to a true mass casualty event.
