Paper Abstract:	Appling evidence based medicine (EBM) and good clinical practice (GCP) in daily practice enhance the quality of health care enormously. Checklists and guidelines help reducing medical malpractice significantly. A way to use checklists and guidelines is to integrate this information into medical documentation. Although some hospital information systems already support physicians with interactive IT support the use of EBM, structured, standardized electronic medical documentation is still very limited. Electronic health records facilitate medical documentation. Electronic health records are designed for exchanging patient information between institutions and systems. The aim of this work is to show a way how electronic health records can be embedded into a comprehensive medical documentation for providing relations between patient information and decision- or treatment processes. Ambitious attempts have been done defining structures and models for electronic health records (EHR) facilitating semantic interoperability between electronic health records - and electronic patient record systems. One of them is the ISO 13606 EHR communication standard. The Web Ontology Language (OWL) was developed for defining and structuring data semantically. OWL enables higher levels of abstraction and expressiveness for defining models than relational database schemata can. Furthermore we used a transformation of the ISO 13606-archetype model to OWL. We introduce an ontology driven application model. The ontology driven application model describes how to derive functionality from ontology knowledge dynamically and using it for application behavior. Furthermore we introduce an application layout that implements the ontology driven application model. We realized a generic implementation being compliant with the ISO 13606 EHR communication standard, to capture standardized electronic health records. This work demonstrates how to use ontologies for developing a semantic web application, and finally proves the introduced models and methods through presenting a prototype.
