The Nordic Centre for Classifications in Health Care (NordClass) is a center for Nordic collaboration on health-related classifications established in 1987.

Goals and activities

NordClass works to promote the understanding of Nordic and international classifications, in particular health related classifications (ICD, ICF and ICHI) within the WHO Family of International Classifications (WHO-FIC).

The goal of NordClass is to inform the Nordic governments about the development of health and health-related classifications and terminologies that is used for statistical data and standards in the member countries. NordClass collaborate with WHO to promote correct use of concepts, content, terminology, and rules for reference.

NordClass organizes its activities in a yearly revised workplan in accordance with WHO terms of reference for WHO-FIC collaborating centres. As a WHO-CC work is performed by participation in WHO-FIC work groups, reference groups and committees.

In parallel, NordClass facilitates collaboration on Nordic issues related to health classifications, that often coincide with the interests of WHO. One example is the establishment of a Nordic information exchange group on the ICD-11 implementation in the Nordic countries, where all members participate and share their experiences.

As the code systems are used for reimbursement algorithms and collection of health data, NordClass also collaborates with the Casemix Centre in Helsinki, Finland and NOMESCO (Nordic Medico-Statistical Committee) in Copenhagen, Denmark. In addition, NordClass performs regular mortality coding comparisons between Canada, and the Baltic, and the Nordic countries.
