The healthcare sector faces challenges which are constantly escalating. Populations are growing worldwide and so is the share of the elderly in society. There is a constant proliferation of new medications, diagnostic methods, medical procedures and equipment, and know-how. This huge progress greatly improves the quality of medical treatment but at the same time increases its costs. Governments and authorities are allocating ever growing budgets to healthcare systems but the increased budgets do not cover the increased costs of providing quality healthcare to the public.
