- The WHO’s ICD lists both mental and physical disorders.
What is International Classification of Diseases (ICD)?
ICD is the basis for identification of health trends and statistics globally and the international standard for reporting diseases and health conditions.
- It is maintained by WHO.
- It is revised periodically and is currently in its tenth revision.
Usages of ICD:
- It is used by medical practitioners around the world to diagnose conditions and by researchers to categorize conditions.
- This comprehensive list is intended to make it easier for scientists to share and compare health information between hospitals, regions and countries.
- It also enables health care workers to compare data in the same location over different time periods. Additionally, public health experts use the ICD to track the number of deaths and diseases.
Design of ICD
- The ICD contains a description of all known diseases and injuries.
- Each disease is detailed with diagnostic characteristics and given a unique identifier that is used to code mortality data on death certificates and morbidity data from patient and clinical records.
- The core of the ICD-10 uses one single list of four-alphanumeric-character codes from A00.0 to Z99.0.
- The first letter of the code designates a different chapter; there are 22 chapters in total (several letters are included in a single chapter together).
- Within each chapter, the four-character codes are divided so that they specify different classification axes. The fourth character (the number after the decimal) is not required for reporting and is used in various ways.
- A version of ICD-11 was released on 18 June 2018 to allow Member States to prepare for implementation, including translating ICD into their national languages.
- ICD-11 will be presented at the World Health Assembly in May 2019 for adoption by Member States, and will come into effect on 1 January 2022.
- This release is an advance preview that will allow countries to plan how to use the new version, prepare translations, and train health professionals all over the country.
