Emergency medical services are a system of emergency services committed to providing emergency and immediate medical care outside of a hospital, transportation to definitive care, in an effort to establish an efficient system through which people do not attempt to transport themselves or administer unprofessional medical care. The primary goal of most emergency medical services is to offer care to those in need of urgent medical attention, with the goal of either adequately treating the current condition or arranging for the person's prompt transportation to a hospital or place of greater care. Philosophically the term emergency medical service developed to represent a transition from a simplistic system of vehicles providing transportation only, to a system in which certified medical care is provided on site and during transportation. However, in some less developed regions, emergency vehicles are still basically a means of transportation to the medical facility that will provide care. Commonly in most countries of the world, citizens of the society at large establish the system for emergency medical services. In the event that the public is unwilling or unable to request such a service, the country often finds other emergency services, businesses or the government and authorities acting to use a system. In other parts of the world, the emergency medical service also takes on the role of transporting patients from one medical facility to an alternative one. This occurs with some frequency because once a patient is tested and provided care at the nearest hospital; may be more appropriate for a variety of reasons why the patient needs to transfer to another facility. As you can see, the relative... center of the document... the same model of Emergency Medical Services, have responded to the health problem of gunshot wounds in very similar ways. They each follow the methods described above to handle traumatic situations such as serious gunshot wounds. The difference, however, lies in the assessment that each doctor has of the injured person. It is up to the attending physician to decide the type of medical treatment on site and when the person is stable or ready for transport. There is no direct evidence to show that doctors in each country have been trained differently to assess these types of situations, so it is difficult to determine whether one country is more successful than another in its emergency medical services system. Each country is more likely to have a similar success rate because it uses a fundamentally similar care system.
