Abstract
Usually a frail aged has a various health and social problems and these problems correlated each other. Thus the highly aged society requires the systematized coordinating function. It requires a multidisciplinary team. Most of the developed countries introduced a network type of integrated care system recently. In this article, we have compared the French Health Network and the Onomichi Medical Association (OMA) system for integrated services as a prototype of future integrated care system in Japan. In the case of Japan, considering the historical and cultural background, it would be more plausible to develop the integrated care system based on the family doctor network system such as the OMA system. In order to facilitate the development of coordination, it would be useful that such a coordination system is financially evaluated in the official tariff table.
