 The result was the evolution of a type of emergency physician called a "Notarzt" who dealt primarily with providing emergency medical care in the out-of-hospital setting.The service delivery model that this approach describes is commonly referred to as the Franco-German model.In the late 1960s and early 1970s, advanced demands lead to the establishment of helicopter ambulance services, dispatch centers, radio communication and general better organization of EMS as well as scientific approaches to provide better emergency care.
