[Trends in primary health version of ICD-11].

The WHO recognizes the importance of a psychiatric diagnostic system in primary care. Regarding the revision of ICD-11 primary health care (ICD-11-PHC), a working group is organized and acts positively. The WG makes the draft of ICD-11-PHC. Some new and interesting disease names, such as ANXIOUS DEPRESSION and BODILY STRESS SYNDROME (BSS), are incorporated in ICD-11-PHC. Revision to ICD-11 continues, and an international Field Trial of ICD-11-PHC by the WHO is planned. Participation in the Field Trial of Japanese researchers is expected. We psychiatrists should closely follow trends in interesting new knowledge in ICD-11-PHC.
