ICD-11: Enhancing Global Health with Stronger Information

The Eleventh Revision of the International Classification of Diseases (ICD-11) has now taken effect as a basis for health reporting to the World Health Organization by WHO Member States (i.e., countries).

In the past decade, the Columbia University WHO Collaborating Centre for Capacity Building and Training in Global Mental Health has been leading collaborations to advance the development, testing, and implementation of the ICD-11 classification of Mental, Behavioural or Neurodevelopmental Disorders. The online version of the official 2022 ICD-11 for use by WHO Member States can be accessed here.

The ICD-11 brings several new advantages for improving health globally:

  • After rigorous scientific research and unprecedented participation of clinicians worldwide, the ICD-11 has been reformulated and expanded to include new categories and conditions that allow clinicians to capture patient health in comprehensive, detailed, and standardized ways.
  • There are numerous new digital features of the ICD-11 that can strengthen the collection and analysis of health information globally, as well as influence health resource allocation.
  • The integration of the Clinical Descriptions and Diagnostic Requirements (CDDR) into the ICD-11 has the potential to powerfully impact country-level mental health policies and practices.
