Let's think of two countries artificially separated by political borders. Both have the same income per capita (~27,700 €) and belong to the EU. The first spends 11.1 % of GDP on health (5,513€ per capita, 77.7% public funding), while the second only 8% (3,898€ per capita, 65.8% públic funding).
Both countries have roughly the same life expectancy at birth. Healthy life expectancy at 65 is better in the country that spends less. The number of visits and hospitalizations is also less. Physicians are also paid less, 18% less in general practitioners income, up to 40% in specialists income.
There is only one border between them, an artificial border created by a treaty to end a war that lasted 30 years. This is the case of part of France and Catalonia. While the first can decide over the size of resources devoted to health, the second has no role on it, by now.
PS. Today at COMB, French health reform. I'll be there. #sanitatfrança
