World Health Organization. (2018) ICD 11.

External website:

ICD is the foundation for the identification of health trends and statistics globally, and the international standard for reporting diseases and health conditions. It is the diagnostic classification standard for all clinical and research purposes. ICD defines the universe of diseases, disorders, injuries and other related health conditions, listed in a comprehensive, hierarchical fashion that allows for:

  • easy storage, retrieval and analysis of health information for evidenced-based decision-making;
  • sharing and comparing health information between hospitals, regions, settings and countries; and
  • data comparisons in the same location across different time periods. 

Uses include monitoring of the incidence and prevalence of diseases, observing reimbursements and resource allocation trends, and keeping track of safety and quality guidelines. They also include the counting of deaths as well as diseases, injuries, symptoms, reasons for encounter, factors that influence health status, and external causes of disease.
