Material and social deprivation and health and social services utilisation in Québec: a local-scale evaluation system

Very few studies have employed local-scale analyses to evaluate how well primary health care and social services reach the most socially and economically deprived individuals. This paper describes a project, conducted in close partnership with decision-makers and practitioners at selected local community service centres (in French, CLSCs) in Quebec, Canada, that developed a system for assessing primary care and social services utilisation by applying deprivation levels defined at the local scale (i.e., according to the distribution of deprivation in individual CLSC service areas). More than 25 years ago, Québec started setting up a province-wide network of publicly financed CLSCs whose mission was to offer first-line health and social services at the local level. Now approximately one Quebecer in four receives at least one service a year from a CLSC. The evaluation system presented in this article is built on deprivation profiles for each CLSC service area and comprises maps, relative indices of service utilisation, and an interpretation framework that facilitates the integration of new data into the decision-making and services planning processes. Study results show that deprivation levels, when defined using local perspectives, correspond more closely to decision-makers' perceptions, that relative indices are sensitive to key determinants of services provision and utilisation, and that the interpretation framework is useful for reassessing intervention strategies.
