ItemThe role of GIS in the management of primary health care servicesESCOBAR, FRANCISCO ; WILLIAMSON, IAN ; WATERS, ELIZABETH ; GREEN, JULIE ; Hugo, Graeme ; Rudd, Chris ( 1997)The application of Geographic Information Systems with health has been relatively slow to develop in Australia. The aim of this paper is to show the role that a GIS can play in the management of Divisions of General Practice (GP). We are proposing to use GIS to allow data in General Practice to be analysed visually through desktop mapping as a way of developing a Practice profile. Most of the research projects in this area in western countries are at this stage of development. The favourable conditions in Victoria, Australia (due to the amount of complete digital data bases) allow us to be more ambitious. Thus the aim of the project presented through this paper is not only to reach a visual representation of the spatial health data but to explore the potential of GIS in the following issues: • the combination of health data with other data such as the location and characteristics of private services related with health, • spatial and thematic queries, • sophisticated spatial analyses related with the optimal distribution and location of the practitioners, • simulations regarding the actual and future demand, and • optimal routing Two Divisions of General Practice, one in rural Victoria and one in the metropolitan area of Melbourne, are being used in a pilot study. The data and results presented in this paper are related to these settings.
ItemAdding dimensions to information: GIS for the divisions of General Practice settingEscobar, Francisco J. ; Williamson, Ian P. ; WATERS, ELIZABETH ; Green, Julie B. ( 1998)With the rapid increase in uptake of information technologies in the health sector, and with concurrent trends in the need to be able to quantify health outcomes, the demands for access to information about a population and health services at a given location has increased. The Geographic Information Systems for General Practice Project was a pilot study in Victoria whereby a GIS was developed for use in the primary health care setting on whose areas the data was collected. This paper discusses the methodology adopted in the project and describes the implementation of the system on the Internet environment. Two different web sites have been prepared for use on the Internet, with access to data contingent on the user population. The practical application of the GIS in the field, and issues relating to evaluation of its utility in the primary care setting are detailed in this paper.
ItemUse of the Internet in the diffusion of GIS for General Practices in Victoria, AustraliaEscobar, Francisco J. ; Williamson, Ian P. ; GREEN, JULIE ; WATERS, ELIZABETH ( 1998)This paper describes the delivery of a Geographic Information System (GIS) product through the Internet for primary health care services provided at general medical practices in the State of Victoria, Australia. The paper details a collaborative research project whose principal aim was to develop a methodology for creating a GIS as a decision support system, for more effective use of information about population and health services at a given location. The methodology employed is based on the ability of a GIS to establish interrelationships between a combination of health, geographic and demographic data. An overview is given of GIS as a technology which allows geospatial data to be analysed, displayed and queried. The results of the project can be demonstrated through a live presentation, detailing specific and generic reasons for the choice of the Internet as the preferred delivery mechanism. The paper concludes with the identification of important issues related to the research and the use of the World Wide Web for Geographic Information Systems and Health.
ItemSpatial data infrastructure management: lessons from corporate GIS developmentChan, Tai On ; WILLIAMSON, IAN ( 1999)It is argued that a corporate GIS is the lowest level in a hierarchy of spatial data infrastructures (SDIs) worldwide. Therefore, SDI development can benefit from a good understanding of the nature and dynamics of development of a corporate GIS. To facilitate this cross-fertilisation, existing definitions of GIS are briefly reviewed in the context of the organisational setting of a corporate GIS. A high level perspective which describes a corporate GIS as making up of GIS modules that play the roles of either an infrastructure or a business process is presented in the paper. The modules are termed infrastructure GIS and business process GIS respectively, with the former supporting the latter. The patterns of GIS development and some long term characteristics of a corporate GIS are identified in a study of the dynamics of GIS development in the Department of Natural Resources and Environment in the State Government of Victoria. These two aspects of the nature of a corporate are also applicable to SDIs and their development. Based on the experience of SDI development in Australia, particularly Victoria, the implications of the observed nature of SDI relationships on SDI management are discussed
