Pharmacy location and medical need: regional evidence from Canada

BACKGROUND: Pharmacists in Canada are assuming an increasingly important role in the provision of primary care services. This raises questions about access to pharmacy services among those with medical care needs. While there is evidence on proximity of residents of Ontario and Nova Scotia to community pharmacies, there is little evidence for the rest of Canada. I thus measured the availability of pharmacist services, both the number of community pharmacies and their hours of operation, at both the provincial and sub-provincial level in Canada. Next, I measured associations of indicators of medical need and the availability of pharmacist services across sub-provincial units. METHODS: I collected data, for each Forward Sortation Area (FSA), on medical need, measured using the fraction of residents aged 65 + and median household income, and pharmacist service availability (the number of community pharmacies and their hours of operation, divided by the FSA population). Linear regression methods were used to assess associations of FSA-level service availability and medical need. RESULTS: There are between 2.0 and 3.3 community pharmacies per 10,000 population, depending on the province. There are also provincial variations in the number of hours that pharmacies are open. Quebec pharmacies were open a median of 75 h a week. In Manitoba, pharmacies were open a median of 53 h a week. The per capita number of pharmacies and their total hours of operation at the FSA level tend to be higher in less affluent regions and in which the share of residents is aged 65 or older. Provincial differences in pharmacy availability were still evident after controlling for medical need. CONCLUSION: Community pharmacies in Canada tend to locate where indicators of health needs are greatest. The impact on patient health outcomes of these pharmacy locational patterns remains an area for future research.
