Healthcare systems in developed countries are facing new challenges that include defining the values, objectives and tasks of sustainable medicine. Near universal access to quality health care is one of the hallmarks of the "European model", but how can we ensure the sustainability of European healthcare systems in an era of aging populations and budget restriction? Even in wealthier countries, such as Switzerland, it has become a real public health problem, as 15% of Swiss citizens waive medical care for financial reasons even while being required to purchase mandatory insurance [1].
