The key problem of the paper is the comparison of selected health financing models used in Croatia, Sweden and the United States of America. Each of the observed countries uses a specific health financing model. The paper analyzes secondary data collected from scientific and professional literature and publicly available databases. The research methods used in the paper are the method of analysis and synthesis, the method of deduction and the method of comparison. The main thesis is that the successful healthcare financing in a certain country does not depend only on the mere determination of the financing model, but also on the implementation quality, the amount of available resources, regulation, demographic factors and many other factors that influence the success of the healthcare financing system itself. According to its characteristics, the Croatian health care system is the closest to Bismarck's financing model, which is characterized by mandatory health insurance, and a high share of public financing. Sweden is most similar to Beveridge's model, which is characterized by tax financing and also has a high share of public financing, while the model used in the USA is most similar to the market model. The Swedish and Croatian model is characterized by universality, while this is not the case in the USA, also, the USA is the country that spends the most funds on healthcare, both in comparison to Croatia and Sweden, but also in comparison to all other countries in the world.
