This study consists of a secondary analysis of data collected during the SIPA demonstration project. Its purpose is to identify the proportion of Adult Day Care (ADC) users as well as the determinants of use in this group of persons 65 years old and over receiving home care services in Montreal. Results show that 18.8% of the sample have at least one ADC presence during a 6 months study period. The following factors increase the probability of ADC use: being younger; not having a university degree; being born outside of Canada or for persons born in Canada, living with a caregiver; receiving help from the CLSC for daily life activities more than once a week; being in the catchment population of an ADC which fees are lower; and for men only, having had a stroke or presenting more functional incapacities.
