Emergency Healthcare Systems (EHS) describes the continuum of patient care from entry into the emergency medicine through 9-1-1 all the way through patient discharge. Participants in the EHS include first responder organizations, 9-1-1 and non-emergency EMS (ambulance) services, acute care receiving hospitals (including trauma, stroke, cardiac, and urgent care centers), rehabilitation facilities, and all of the support personnel, facilities, and services supporting these efforts. The mission of the EHS Department is to provide central support to weave together plans and efforts as well as navigation support to bolster regulatory requirements for all EHS participant NCTTRAC members. EHS staff also support each of the functional NCTTRAC committees in their efforts to develop required system plans for trauma, stroke, and cardiac care, as well as regional patient care guidelines. Additionally there is support for the regional patient care registry REG*E and the regional System Performance Improvement Committee and Physician Advisory Groups.
