  Elder people are becoming a predominant aspect of our societies. As such,
solutions both efficacious and cost-effective need to be sought. The approach
pursued so far to solve this problem used to increase the number of people
working in the health sector, e.g. doctors, nurses, etc. This increases the
costs, which is becoming a big burden for countries. In this paper we propose a
new concept in the health management of elder people, which we name as
"participant". We propose the "participant" concept to encourage elder people
to participate in those group activities that they are able to. Their roles in
these activities are not passively requesting help, but actively participating
to some healthcare processes. Characteristics of the participant approach are
that medical resources are efficiently spared with this model, and the social
network of the elder people is kept. A "virtual community" for mutual
assistance is set up in this paper, and the simulations demonstrate that the
"participant" model could fully utilize the community resources. Furthermore,
the psychological health of the elder people will be improved.
