The WHO Adverse Drug Reaction Terminology (WHO-ART) was developed and is maintained by the Uppsala Monitoring Centre, the World Health Organization (WHO) Collaborating Centre for International Drug Monitoring.
WHO-ART is used for coding clinical information related to adverse drug reactions.
WHO-ART is a four-level hierarchical terminology, which begins at the body system/organ level classes. These classes consist of broad grouping terms, which consist of more specific preferred terms. WHO also contains commonly used terms, called included terms, that act as entry terms for the preferred terms.
