Development of systems of care for ST-elevation myocardial infarction patients: the emergency medical services and emergency department perspective.

Current System of Care Emergency Medical Services System Design Prehospital EMS systems have 3 major components: emergency medical dispatch, public safety (fire and law enforcement) first response, and EMS ambulance response. Each of these operates within a broader emergency care system, which includes acute care facilities and regionalized healthcare services. In most states, an EMS regulatory entity within the state government oversees the emergency care system. Many states have regional EMS councils and advisory boards that function with varying levels of authority.
