ICD-11 Revision of Mental Disorders: the Global Standard for Health Data, Clinical Documentation, and Statistical...

Mental health conditions in the World Health Organization (WHO) European Region affect more than 10% of the population, with 140,000 lives lost annually to suicide. Comorbidity with other diseases is high. However, basic mental health care is received by less than a third of patients. The COVID-19 pandemic has revealed the vulnerability of mental health services to disruptions and underscored the need to integrate mental health into response strategies. One of the flagship initiatives of the WHO European Programme of Work (EPW), 2020-2025: 'United Action for Better Health in Europe' is the establishment of a Mental Health Coalition at the European level. In this framework, reporting of health statistics using the International Classification of Diseases 11^th Revision (ICD-11) will begin on 1st January 2022. Clinical utility, scientific rigour and wider cultural applicability were all of prime importance in the development of the ICD-11. The 11th Revision was the end product of the most extensive global, multilingual, multidisciplinary and participative process ever undertaken for this task, involving more than 15,000 experts from 155 countries, representing approximately 80% of the world's population. With the adoption of the ICD-11 and the priority being given to mental health, new ideas based on the 30 years of research since the approval of the ICD-10 will be widely adopted and applied.
