The Danish National eHealth Authority has published a number of national reference architectures describing how interoperability can be achieved between eHealth systems in Denmark by recommending a range of architectural frameworks, standards, and profiles.
The scope of this reference architecture document is the sharing of patient related documents and images across administrative domains/sectors and IT systems.
The main recommendation of this document is to design systems according to IHE profiles, in particular the XDS (Cross-Enterprise Document Sharing) specification.
The Document Sharing page offers an introduction to XDS and the implementation of document sharing mechanisms in 4S software.
The scope of this reference architecture document is the transfer of health data collected by the citizens themselves from their homes using personal devices (PCs, smartphones, blood pressure monitors, exercise bikes etc.) to the clinical IT systems used at hospitals and general practitioners.
The main recommendation of this document is to design systems according to the Continua Design Guidelines.
The Continua Guidelines 101 page offers the beginner's guide to understanding the Continua Design Guidelines.
The scope of this reference architecture document (which is only available in Danish) is information security in health IT systems. The document lists a number of overall principles and trust models and proposes different architectures to support this.
