Revision of the International Classification of Diseases (ICD-11)

Chronic pain affects an estimated 20 percent of people worldwide and accounts for nearly one-fifth of physician visits. One way to ensure that chronic pain receives greater attention as a global health priority is to improve the International Classification of Diseases (ICD) diagnostic classification.

In response to this need, IASP created an international task force of pain experts headed by past President Rolf-Detlef Treede that, in close cooperation with the World Health Organization (WHO), has developed a proposal for a systematic and pragmatic classification of chronic pain. The goal is to create a classification system for the upcoming 11th revision of the ICD that is equally useful in primary care and specialized pain management settings.

We need your help! An important component in the submission of the chronic pain classification to WHO is field testing data. Your participation will help ensure the inclusion of the classification proposal in ICD-11, which will contribute to the improvement of the diagnosis and treatment of chronic pain. The field testing will occur in two parts – an introductory training material and knowledge test, followed by a study on the WHO ICD-FiT platform.
