A Model-Driven Approach for the German Health Telematics Architectural Framework and the Related Security Infrastructure
Shared care concepts such as managed care and continuity of care are based oil extended communication and co-operation either between different health professionals, or between them and the patient. Health information systems and their components, which are very different in their structure, their behaviour, the respective data, and their semantics as well as regarding implementation details used in different environments for different purposes, have to provide intelligent interoperability. Therefore, flexibility, portability, and future-orientation must be guaranteed using the newest development of model driven architecture. The ongoing work for the German health telematics platform based on an architectural framework and a security infrastructure is described in some detail. This concept of future-proof health information networks with virtual Electronic Health Records as core application starts with multifunctional Electronic Health Cards. It fits into developments currently performed by many other developed countries in Europe and beyond.
