The codes IBUI are related to the thesaurus developed in Belgium in support to General Practitioners. The thesaurus is built around medical concepts. A “concept” is a fixed unit, clearly defined, of clinical notions (“clinical thinking”), such as e.g. “acute bronchitis”. Those concepts are used as clinical definitions which can be used as text, symptoms description, procedure, diagnostic, risk factor, etc.. in the Electronic Health Record. They are furthermore translated in Dutch and French so that linguistically they can be considered as perfectly similar. Each concept is linked at least to one couple ICPC2-ICD10. A link with 2 or more couples is possible as a concept can be apprehended from different angles when dealing with medical classification. However codes related to procedures/interventions are not coupled to ICD but only to a single ICPC code. The link which unites the french and dutch concepts to their couple(s) of code(s) is created through an IBUI (Identifcateur Belge Unique / Belgische Unieke Identificator); this IBUI is thus a pure technical instrument without any scientific or analytical value. To each concept is attached a list of several “search terms”: the terms of the concept itself, the synonyms or other useful terms to search the concept.
The IBUI associates those key-words to the concepts for each term separately. French and Dutch search terms are independent from each other and thus do not match. They only determine the concept in the same language than the searched term.
We only provide here a small extract for illustration purpose. The thesaurus has been made available to users from January 2008 on. It can be downloaded from the FPS Health site . The IBUI thesaurus is now a part of 3BT.
