Professor of medical informatics, University of Rouen, France The International Classification of Primary Care (ICPC-2) is available in many languages and ranks the most common clinical problems encountered in primary care. The non-clinical concepts treated by family physicians were described following careful analysis of family physician communications at many congresses and referred to as Q-Codes. ICPC-2 in 22 languages including process codes and Q-Codes in 12 languages were published online on the Health Terminology/Ontology Portal (HeTOP, developed at the Rouen University Hospital) under the acronym 3CGP for “Core concept Classification in General Practice / Family Medicine”. The headings in both classifications have an Unique Resource Identifier (URI) and are available in both Excel and Web Ontology Language (OWL) formats. The topics and codes are linked to the large classifications existing through the HeTOP multi-terminology server. 20% of ICPC codes and all Q-Codes are related to corresponding MeSH concepts with automatic access to a bibliography on PubMed. New translations can be introduced directly from a standardized Excel file. They can also be edited online in an advanced mode. 3CGP is used as a resource for the teaching of family medicine in Belgium (French speaking), Portugal and Uruguay. The French-speaking doctors in training (ULB-ULg-UCL) and the students of the University of Coimbra in Portugal use it to index their work of end of study (master thesis). In Uruguay, the Department of General Medicine indexes a grey literature database with this system. The HeTOP application saves action logs which makes possible the analysis of the site traffic (excluding robots and scientists with edition permission). The poster, which gives access to the website and Uniform Resource Locators (URIs), shows available data at the end of September 2019. It is noted that ICPC was the subject of 1,253 individual searches with 3,949 views (surfing on the items) in August 2019, which is to this day the highlight of monthly attendance. The non-clinical concepts exposed in the Q-codes were the subject of 1,597 searches and 9,887 views in February 2019, during which time Belgian students are encouraged to find the research theme for their final work. Unsurprisingly, the most used language is French, followed by English, then Portuguese and Spanish. More than 500 different sections of ICPC-2 were consulted, including all procedure codes. All sections of the Q-Codes (i.e. 182) were consulted between 100 and 550 times. Although the use of 3CGP for teaching general medicine and the indexation of its work has not yet been the subject of a validation study, it is shown that the system enjoys factual validation.
