Community Care Access Centres (CCAC) were established by the Ministry of Health and Long-Term Care in 1996 to help the public access government-funded home and community services, and long-term care homes. Currently CCACs capture client utilization data and costs of direct home-care services received by each client, but not the amount of care coordination (CC) activity provided to each client. In the absence of measuring care coordination resource use by client, CCAC care coordination costs must be allocated to home care clients using a methodology which approximates the actual client use of care coordination resources.
