Conclusions: Electronic Health Record data may be effectively extracted from Entity-Attribute-Value based Electronic Health Record systems using the suggested approach. As a prerequisite for applying our approach, the internal data model of the Electronic Health Record system and the archetype must overlap in a way that a semantic mapping between them is possible. The system must further provide an XML interface which permits the export of the source documents in conventional format. The export must include data and metadata that are mandatorily postulated by the archetype and the ISO/EN 13606 Reference Model. (Source: International Journal of Medical Informatics).
