Data from the Manitoba Study of Health and Aging were used to compare the utilization and direct costs of formal community care services among the elderly diagnosed as persons with no cognitive impairment, with cognitive impairment/no dementia and with dementia. The results of the analyses indicate that, in addition to living arrangement and limitation on basic and instrumental activities of daily living, mental function diagnosis is an independent predictor of community care use. A diagnosis of dementia increases the likelihood of community care use over those with unimpaired mental functioning, whereas cognitive impairment without dementia does not. The three diagnostic groups differ in the type of services used. Standardization by age, sex and the other variables which significantly affect the need for community care can help a program improve its ability to project realistic cost estimates.
