Die Entwicklung der ICD-11 Kapitel über psychische Störungen wird von drei Gruppen von Feldstudien geleitet: Formative Studien, internetbasierte Studien und Klinik-basierte Studien. Formative Feldstudien zielten darauf ab Entscheidungen über die Grundstruktur der Klassifikation und eine Beurteilung der Konzeptualisierungen von Krankenhausärzten über die Beziehungen zwischen den Kategorien von p...

Background: Mental disorders are alterations in several functional domains of human beings that trigger greater morbidity and mortality if not adequately addressed. The International Classification Diseases 11th Revision (ICD11) is a recently approved global modern system to guide clinical practice faced with these other conditions. State the art: Despite imminent implementation this member sta...

Grief is a natural and expected reaction to the loss of a loved one. However, it has for long been observed that grief following a death can also lead to disease. Neither of the two classification systems for mental disorders, the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD), has so far included a separate diagnosis for grief....

Background The WHO International Classification of Diseases, 11th version (ICD11), has proposed two related diagnoses following exposure to traumatic events; Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD). We set out to explore whether the newly developed ICD-11 Trauma Questionnaire (ICD-TQ) can distinguish between classes of individuals according to the PTSD and CPTSD symptom pr...

Most rare diseases are absent in the International Classification of Diseases (ICD10) and those with a specific code are often misclassified. As a consequence, morbidity and mortality due to rare diseases is invisible in health information systems. To overcome this difficulty, Orphanet (http://www.orpha.net) has established a partnership with WHO to ensure a fair representation of rare diseases...

Having codes for each and every rare disease (RD) would help European and national health authorities obtain a better knowledge of healthcare pathways and of their impact on specialised health care services (centres of expertise for instance) and on budget. It would also allow having sound data on the epidemiology and natural history of RD, and provide data for clinical research which is critic...

The work by Kendler et al. (1) in this issue of Acta Psychiatrica Scandinavica replicates the phenotypic correlation between borderline personality disorder (BPD) and the trait of neuroticism from the fivefactor model of personality (FFM; 2) within a large twin sample. This study also extends previous work by using behavioural genetics to examine the underpinnings of the relationship between BP...

The World Health Organization (WHO) in collaboration with several international stakeholders have started recently the work on the International Classification of Traditional Medicine (ICTM), which will provide a standardized system for encoding and collecting health statistics data related to Traditional Medicine practice throughout the world. ICTM is represented in OWL, and is developed by Tr...

From the beginning, practicing psychiatrists and other mental health professionals around the globe have played an integral role in the development of the ICD-11 classification of mental and behavioural disorders by the World Health Organization (WHO) Department of Mental Health and Substance Abuse. A central aspect of practitioners’ contribution has been their participation in a series of deve...

Health information technology (HIT) standards are not new. Arguably, they date to the canonical list for causes of death in the London Bills of Mortality of 1528, which was later formalized during the middle of the 19th century into what we now recognize as the International Classifications of Diseases (ICD). Beginning in the middle of the 20th century, HIT standards evolved beyond vital statis...
