Focused research in emergency medical systems in Asia: a necessity for trauma system advancement

Abstract Since trauma is a growing health problem worldwide, emergency trauma care including emergency medical services (EMS) is becoming an integral part of the healthcare system. The optimal EMS which will improve access to trauma care, will be different in each country because of different healthcare systems, trauma etiology, and economic situations. To adopt models that have succeeded in developed countries is not always appropriate. In order to identify the optimal EMS model in developing countries, comparing the systems among many countries in detail and examining their advantages and disadvantages would be necessary. Therefore, this article tries to identify important elements of EMS to achieve mature EMS systems based on comparisons of 7 Asian countries, and discusses the need to conduct more detailed and extensive comparisons.
