Abstract: enior people need special emergency cares, which are not extremely compatible with the current services provided at emergency departments (ED). How important is this issue as a priority in the health care systems? The number of senior people, over 65 years old, is rapidly growing in the United States, as they represent 12% of the national population, that is projected to increase to 21% by 2050 [1-4]; moreover, the population of over 85 will be three folded in the next four decades [1-4]. Comparing to the other age groups, because of experiencing more serious and complicated health problems, seniors refer to EDs more than other age groups [5-8]. In other words, as people age, frequency of the visits per person at EDs increases [8]. In fact, the elderly admission rate has been increasing for the last ten years [5]. So a huge, realistic and crucial demand for supplying emergency services is facing that will noticeably increase in the future. The question is why the current emergency services providing in EDs are different from services in Geriatric Emergency Departments (GED).
Some critical and considerable differences between EDs and GEDs are related to the physiological changes occur in the elderly as a period of life, such as decrease physiological capacities in vital human body organs and systems, including immune system. The prevalence and languishing status of the chronic disorders are the important differences between seniors and other age groups. The other contrasts are to do with the design of ED buildings and services need to be compatible with these different needs.
