World Health Organization

The Australian Institute of Health and Welfare is designated as the World Health Organization Collaborating Centre for the Family of International Classifications (WHO-FIC) in Australia. The Australian Collaborating Centre (ACC) assists the WHO with their efforts to support national and international health information systems, statistics and evidence. The ACC is part of a Network of collaborating centres that contribute to the development, dissemination, maintenance and use of products that help categorise concepts in health and the health system.

WHO Family of International Classifications (WHO-FIC)

The WHO-FIC includes reference classifications, derived classifications, and related classifications. The reference classifications serve as the global standards for health data, clinical documentation and statistical aggregation. They enable capture of the following health areas: diseases, health problems, body function, body structure, activity, participation and interventions. They include:

• The International Statistical Classification of Diseases and Related Health Problems (ICD)
• The International Classification of Functioning, Disability and Health (ICF), and,
• The International Classification of Health Interventions (ICHI).

The other classifications are either based on (derived classifications) or separate to (related classifications) these three reference classifications. Together, the classifications are known as the Family of International Classifications and the network of collaborating centres is known as the WHO-FIC Network.

These products are used in different ways across different countries. Tables 1, 2 and 3 below describe how the different classifications of the WHO-FIC are used in Australia.

• Education and Implementation Committee (EIC)
• Family Development Committee (FDC)
• Informatics and Terminology Committee (ITC)
• Classification and Statistics Advisory Committee (CSAC)

• Functioning and Disability Reference Group (FDRG)
• Morbidity Reference Group (MbRG)
• Mortality Reference Group (MRG)
• Traditional Medicine Reference Group (TMRG)
