Dysfunction of health care has been a hot issue recently. Financial and human resource problems have been perceived by many of us, although a pile of other interrelated problems also appears in this field. However, several of them could be improved with adequate management methods. In order to understand the changes previously carried out in health care, it is vital to get know the legislations documenting national and international tendencies. The multi-aspect research is based on documentations, comparative analysis and evaluation of statistics from the given field. Besides them, the financial system, the state’s participation, and the service systems also need to be taken into consideration. Due to former reorganizations of health care, many different types of organizational structures connect with one another, and for profit and non profit organizations are interwoven. The complicated situation suggests that our research into this topic is rather timely. By revealing the health care systems of different countries, two basic tendencies seem to prevail. There are systems, in several states, which make cooperation easier, while there are differences, caused by historical events, whose abolition would serve everybody’s interest.
