The intent of this study was to examine the effect of cognitive status on the use of inhome services by caregivers and their elders. Data from the screening, clinical and community-caregiver phases of the Manitoba Study on Health and Aging (MSHA-1) were analysed utilizing a modified Andersen-Newman model. The findings indicated that those with dementia were more likely to use personal care services and use two or more inhome services than caregivers and their elders with no cognitive impairment and those with cognitive impairment but no dementia. Functional status of the elder and living arrangement of the caregiver and elder were strongly associated with the use of specific inhome services and with overall use. Policy and research implications of the findings including other significant factors such as caregiver employment, are presented.
