Health Data Management with an Archetype Driven EHR System in Low Ressource Environments (EHRFlex)

A semantically interoperable Electronic Health Record (EHR) is one of the most challenging research fields of health informatics. EHR standards that formally describe health data structures are a prerequisite for sharing medical records. CEN EN13606 is one of the most promising approaches to solve this problem since it covers the technical needs for semantic interoperability and, at the same time, incorporates a mechanism (archetype model), which allows clinical domain experts to participate in the definition of the medical content of an EHR system. In this paper we present EHRflex, a generic archetype driven system that provides a flexible EHR solution. The graphical user interface is generated on-the-fly and allows to capture data according to the archetype descriptions of the user. EHRflex shows that the dual model approach of CEN allows the separation of software development and definition of clinical concepts. This affords to satisfy the most diverse and constantly changing data requirements and to save cost-intensive software adjustments at the same time.
