Equitable access and distribution of health care services for rural and remote populations is a substantial challenge for health workforce planners and policy makers. Geospatial examination of access to health care considers both need and supply dimensions together to determine spatial access scores which contribute to a greater understanding of potential inequity in accessibility. This geospatial investigation explores geographic variation in accessibility to primary health care services utilizing combined access scores for family physicians and nurse practitioner services in urban and rural communities in the Canadian Prairie provinces of Saskatchewan and Alberta. An index of access scores was developed using a floating catchment area framework and a census subdivision geographic unit. Information about family physician and nurse practitioner practice locations and spatial population data were obtained …
