The effects of Quebec home aid services on the utilization profile of sociosanitory resources: a substitution study.

The development of home aid services in Quebec is based on the hypothesis that this new program will help to maintain at home people who would otherwise be institutionalized and also contribute to reducing costs in the health care sector. Accordingly, home aid services can be viewed as a substitute for conventional health care services. This study evaluates utilization modifications of health care services subsequent to the introduction of a home-aid program in October 1977. A modified, non-equivalent, control group design was used on a target population including all residents aged 65 or more in one region of Quebec. Multiple regression was used to explain variations in resources utilization in relation to population characteristics and different health care settings. Results for the utilization of hospitals are discussed. We discovered that the anticipated substitutive effects of a home-aid program on the use of health care services cannot be ascertained.
