The influence of system factors upon the macro-economic efficiency of health care: implications for the health policies of developing and developed countries.

This paper aims to clarify the global association of system factors with the attainment of health policy goals, through economic analyses of cross-country data. In the case of OECD (the Organization for Economic Co-operation and Development) data for 1990, the variation in total expenditure on health among 24 countries can be explained by various factors including Gross Domestic Product (GDP). Among these, the variables representing the level of public sector involvement through social protection or public-private mix within a health care system, such as the Public-to-Total Expenditure Ratio, Coverage Rate and Public Cost Sharing, are significantly negative when factors such as GDP are controlled. This suggests that countries attaining higher equity or accessibility are in a better position to gain higher cost-containment or macro-economic efficiency. The results of this study may be helpful for developing countries searching for a long-term health care system as well as for developed countries facing health care system reforms.
