Short Description: The objective of the HANSA project was the specification, implementation and evaluation of the Distributed Healthcare Environment (DHE) as a European Middleware architecture for shared care health information systems.
Applicable for both legacy and newly developed systems, the architecture was based on the entity-relationship paradigm defining process-related components (managers) to realise complex services. Such managers are, e.g., the patient manager, the activity manager as the basic component, the health data manager, the users and authorisation manager, the resources manager and the cost and performance manager. The DHE approach implemented the CEN TC 251 Health Information Systems Architecture (HISA) standard. The DHE components provided services to the application layer and needed services from an underlying Bitways layer. This layer consisted of the Network Independent Communication Environment (NICE) and the network.
The first comparison of the different concepts for shared care health information systems including DHE, CORBA and HL7 was published in: B.Blobel; M.Holena: Comparing middleware concepts for advanced healthcare system architectures. International Journal of Medical Informatics 46 (1997) pp. 69-85.
