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.
