History of ICD

The International Classification of Diseases is the standard diagnostic tool for epidemiology, health management, and clinical purposes. This includes the analysis of the general health situation of population groups. It is used to monitor the incidence and prevalence of diseases and other health problems, providing a picture of the general health situation of countries and populations.

International Classification of Functioning, Disability and Health (ICF)

The International Classification of Functioning, Disability and Health, known more commonly as ICF, is a classification of health and health-related domains. As the functioning and disability of an individual occurs in a context, ICF also includes a list of environmental factors.

International Classification of Health Interventions (ICHI)

This International Classification of Health Interventions is currently under development. When completed, it will provide Member States, health care service providers and organizers, and researchers with a common tool for reporting and analysing the distribution and evolution of health interventions for statistical purposes. It will be structured with various degrees of specificity for use at the different levels of the health systems, and will use a commonly accepted terminology in order to permit comparison of data between countries and services.

Derived classifications are based on the reference classifications (i.e. ICD and ICF). Derived classifications may be prepared either by building on the reference classification structure and categories to provide additional detail beyond that provided by the reference classification, or they may be prepared through rearrangement or aggregation of items from one or more reference classifications. Links to the related and derived classifications are coming soon.

WHO has designated a number of Collaborating Centres to contribute to the work on the development, dissemination, maintenance and use of the WHO Family of International Classifications to support national and international health information systems, statistics and evidence.
