There is a rapidly growing interest in emergency medicine (EM) and emergency out-of-hospital care throughout the world. In most countries, the specialty of EM is either nonexistent or in an early stage of development. Many countries have recognized the need for, and value of, establishing a quality emergency health care system and are striving to create the specialty. These systems do not have to be high tech and expense but can focus on providing appropriate emergency training to physicians and other health care workers. Rather than repeatedly "reinventing the wheel" with the start of each new emergency care system, the preexisting knowledge base of EM can be shared with these countries. Since the United States has an advanced emergency health care system and the longest history of recognizing EM as a distinct medical specialty, lessons learned in the United States may benefit other countries. In order to provide appropriate advice to countries in the early phase of emergency health care development, careful assessment of national resources, governmental structure, population demographics, culture, and health care needs is necessary. This paper lists specific recommendations for EM organizations and physicians seeking to assist the development of the specialty of EM internationally.
