The 11th Revision of the International Classification of Diseases and Related Health Problems was released as a version for implementation in June, 2018. The ICD-11 was finally approved at the World Health Assembly in May, 2019, which is after more than a decade since the International Advisory Group was established in 2008. If the clinicians, or the end users of the diagnostic classification system, find it more useful, it helps accumulate better health data in the long run. For the World Health Organization, which aims to reduce disease burden, good health information is critical in its decision making. This paper presents the attempt of the ICD-11 to reduce burden by addressing clinical utility, while introducing various field studies conducted to this date to inform the revision process. The revision process has taken up voices of clinicians from the very beginning, and the multi-cultural and multi-lingual perspective has been maintained throughout the process, including the design of the overarching architecture and assessment of utility. We expect that the ICD-11 will be well utilized, thereby contributing to reduction of disease burden.
