Abstract:
Enterprise Application Integration (EAI) and HL7 (Health Level Seven) messaging are well established technologies in healthcare environments. Due to the widely adoption of HL7 messaging, especially the version 2, in the healthcare domain and its flexibility, many vendor specific implementations exist. To integrate these systems, messages have to be adapted to the vendor specific requirements, even if the functionality is nearly the same. This leads to an increasing number of special interfaces and decreased maintainability. This paper shows a generic architecture for reusable interfaces for HL7 messaging by considering reusability at data level and interface level and the results when applied to a real production EAI environment of an austrian healthcare provider.
