Location of community pharmacies: A rational approach using geographic information systems

Abstract

Abstract The role played by community pharmacies in primary and community care and the extent to which they meet patient and customer needs has come under close scrutiny in Great Britain recently following publication of reports from the National Audit Office and House of Commons Public Accounts Committee.1,2 Spatial variations in the provision of pharmaceutical services and their physical accessibility to different sections of the community are issues at the forefront of the current debate. This paper reports on recent research, being undertaken in the North West region, to develop a systematic approach to the analysis of community pharmacy location drawing on the fields of geodemographics (ie, neighbourhood classifications) and geographical information systems (GIS). Comprehensive information is being assembled about individual pharmacies, the services they provide, the types of residential neighbourhood in which they are located, their advice-giving role, and their proximity to general practitioners, other health care outlets and residential homes. Data sources include the pharmaceutical register, the family health services authorities (FHSAs) and surveys of pharmacists and health care professionals. This is being augmented with digitised boundary information including the road network and small area statistics on demographic structure, social conditions and deprivation. These data are being utilised within a computerised system to identify how well the current distribution of pharmacies accords with expectations and alternative resource deployment scenarios. Particular attention is being paid to the identification of gaps in provision and areas of over-provision.
