Developing national health information in Australia.
Two significant developments in the past two years have given impetus to development of health information in Australia. In March 1993, the former National Minimum Data Set was revised and published as the National Health Data Dictionary. Second, establishment of an agreement in June 1993, between the Commonwealth and State/Territory government health authorities, the Australian Bureau of Statistics, and the Australian Institute of Health and Welfare initiated a process of working cooperatively to develop national health information. Australia, like many other countries, suffers from inconsistent health data definitions, lack of timely data, poor data quality, gaps in data coverage, and barriers to accessing the data. The National Health Information Agreement [1] came into effect on June 1, 1993 and seeks to provide a national framework and processes to improve national health information, that is, information on health of the population; determinants of the population's health; provision and utilization of health promotion and disease prevention programs and health services including: outcomes and outputs, resource use and costs, access by and distribution to population groups; relationships between these elements; and the language necessary to facilitate provision of services and collection of national health information. The major implementation mechanism of the Agreement is a rolling three-year National Health Information Work Program of national health information activities. The activities range from development work on standard hospital charts of accounts, on health outcome measures, and on new collections such as outpatients to improved definitions and the enhancement of existing collections such as mental health and vital statistics. The Work Program is published annually. A first priority is to improve the data collections available. This is being achieved through the setting of national data definitions and standards. The Agreement recognizes the National Health Data Dictionary (NHDD) as the authoritative set of national definitions and is a significant initiative aimed at improving Australia's health information. The dictionary is the repository of the agreed common language, use of the definitions facilities the description and comparison of health and health services nationally [2]. The National Health Data Dictionary currently covers institutionally provided health care, the national health labor force, and is expanding to cover other major areas, including outpatient services, community care, and mental health. The NHDD is reviewed and maintained by the National Health Data Committee and the overall coordination of definition development projects and publication is undertaken by the Institute. The placement of an agreed definition in the NHDD does not automatically mean that it has a place in a national data collection. The use of the dictionary definition will allow comparison by and between service providers. In order for a data item to be eligible for inclusion in a national minimum data set, the definition of that item must be contained in the NHDD. During the first three months of 1995, the Australian Institute of Health and Welfare will conduct a national project to develop a model for the health system in Australia. The model will provide a common vocabulary and information architecture in order to facilitate better quality health information, and consequently better health for Australians. It is expected that the development of the model will bring several benefits including facilitating the more rapid and accurate assembly of appropriate clinical information to support improved customer service and outcomes, provide a mechanism for achieving better quality information, reduce the costs of data collection; provide enabling mechanisms for the integration of systems via data standards and reduce the costs of acquiring information systems through reduced development and tailoring costs for suppliers.
