As the homeless elderly population is increasing in numbers, Australia is facing the challenge of caring for this group of individuals. The best intervention to assist these individuals is:
a) Identify therapeutic standards to which the health care community is held
b) Restrict access to costly procedures and providers
c) Provide homeless elderly persons with a comprehensive multiservice center, all under one roof
d) Develop health care resources for homeless elderly persons who find it difficult to find the money to supplement Medicare and PBS
