Health is one of the greatest blessings. It has always been a key factor in   the lives of individuals and societies. For this reason, the science of medicine has continuously maintained its importance throughout history. Today, medicine has also been shaped by the rapid advancements in socio-economic fields, and an ever-expanding spec- trum of new diseases and treatments has made continuous development essential. One of the most important indicators of a    country's level of development is the quality and accessibility of the healthcare services it provides to its people.
