Health is the most precious human value. It contributes to the economic potential of the country and therefore requires the interest of both the state and the public authorities. How can countries really influence the health of their inhabitants? No doubt, appropriate number of hospital beds and practising physicians are important. But what else does matter? Health expenditure has a significant role in national economies. We examine healthcare systems efficiency in 27 European countries using Data Envelopment Analysis (DEA). Then we compare the impact of health expenditure per capita and the health expenditure share of GDP to the efficiency scores of compared countries. We show that the share may be preferable to use in DEA calculations, because it takes into account the "country’s wealth".
