The quality of emergency services is one of the indicators describing the health status of countries. Moreover, the specialization of services and targeted response to any accident or disease has been the priority of pre-hospital emergency operations in some leading countries. This study aimed to compare the special services provided in the emergency department of several selected countries. This was a comparative study that was done in Isfahan in 2022. Data were collected by reviewing the literature provided by libraries and emergency websites of selected countries. We selected countries based on the accessibility of information in two groups of developed countries and countries with the same income and population as Iran including Germany, France, The United States, Australia, Britain, Malaysia, and Turkey. Data were classified and compared based on staff, vehicles, and specialized services. Emergency staffs in most countries were of different skill and training levels. Ambulances varied in equipment types in various land, air, and sea forms and dimensions. Developed countries had more modern ambulances and equipment. France and Germany were operating more especially. Specialized teams are dispatched only in the United States and Germany. Existing studies have shown the adequacy and effectiveness of these teams in reducing complications and mortality and improving the prognosis of patients. The use of specialized teams appropriate to each emergency based on the specific and targeted response is effective in improving the prognosis of patients. The results of this study are suggested to beneficiaries to improve the quality of emergency care and reduce complications and potential causalities.
