Hospitals are extremely important, sensitive and strategic elements of the health system in any country. Reducing staffing level, streamlining and improving their management are major objectives of reforms. Like any institution, each hospital has a mission to perform and function. Therefore, a hospital can excuse its existence only insofar as it is effective; this is the only way to fulfill its mission. In other words, the mission of any hospital is to provide the specific medical services needed to solve the patients' (efictivly) health problems in the best (quality) and in most economic (efficiency) way as possible.
