The rise of the average age of the population in Shimane Prefecture has become more and more conspicuous in these years. According to the estimation of the future population the aging phenome-non in Shimane Prefecture is going about fifteen years ahead of the average of Japan. Therefore it is significant to perform a community experiment of the comprehensive health care for the elderly in this prefecture, in the sense that its results will offer many useful experiences to other districts of Japan, where the aging of the population is proceeding a little more slowly.
We carried out an experiment called “the Service Package System for the Bedridden Elderly”, in Sada-cho, Shimane Prefecture in cooperation with Sada-cho, Izumo Health Center and Izumo Medical Association. It is an improvement on the health care system for the bedridden elderly and their family, which has been performed in Scandinavian countries.
The results of our experiment obviously showed the existence of many problems stemming from the lack of integration among different fields such as health care, medical care, social welfare, working and cultural life. To establish the comprehensivehealth service system for the elderly and their family the integration of these fields is most urgently demanded.

In order to develop the health care system for the elderly we need to analyse fundamentally the phenomenon that the average age of population in each community is rapidly becoming older, as well as we have to grasp life conditions and health needs of old people. We investigated the rate of increase or decrease of population, rate of the elderly living by themselves and the index of the aging of population of each community, classified these communities into several types, and presented the points necessary to develop a community-based comprehensive health care for the elderly as to each type by considering the meanings the indices of health care, medical care and social welfare of the communities disclose.
