A number of the reports below focus on the historical technical development of information about data.

The national data dictionaries are a reference of standardised, accepted terms and protocols used for data collection in the Health, Community Services and Housing sectors. These terms reflect a vast array of health, community services, housing and research expertise.

National Health Data Dictionary version 14 

Publication |

The National Health Data Dictionary (the NHDD) is a national resource which health jurisdictions use to ensure the consistency and comparability of all data collected under the National Health Information Agreement. It is increasingly being used as a resource to standardise data collections that are not mandatory for national collection. It is vital that the health care community continues to standardise the meaning and representation of data used for both clinical purposes and statistical analysis. The use of the NHDD is an important step in this process. With the comparability of data collected based on definitions in the NHDD, information collected by jurisdictions throughout Australia can provide meaningful input to community discussion and public policy debate on health issues in Australia. The aim of such discussion is to improve the quality and safety of health care for all Australians. Version 14 has been downloaded from METeOR which is an internet registry for development, registration and dissemination of metadata based on the latest version of the international standard ISO/IEC 11179 Information technology-Metadata registries (MDR) in 2003.

Statistical data linkage in community services data collections 

Publication |

This report is the outcome of a major project conducted by the National Community Services Information Management Group with the financial support of the Community Services Ministers' Advisory Council. The potential benefits of statistical linkage for policy, research and planning purposes are of increasing interest across jurisdictions and in the health and community services sectors. The report raises key issues for wider consideration and discussion concerning the appropriate conduct of statistical linkage projects using community services data and the appropriate mechanisms for the protection of individual privacy.

Use of the Dictionary will help ensure that community services data in Australia are uniform and of high quality. The format for metadata items is based on international standards.

National Classifications of Community Services 

Publication |

The classifications of community services contained in this publication have the potential to improve the quality of Australian community service data and to contribute to policy development and planning within Australia.
