"Modeling and Implementing Medical e-services";
Report No. TUV-1841-2004-14, 2004; 36 pages.

On the one hand Web services are gaining increasing attention. A lot
of standardization has improved their stability and range of application.
Composition and coordination techniques forWeb services enable an application
integration effort beyond loosely coupled systems. On the other hand
medical e-services are covered by the DICOM and HL7 communication
protocols and profiled by the IHE (Integrating the Healthcare Enterprise)
technical framework. Standardization is more extensive, most workflows
are well defined and integration is tighter than in most other domains. Nevertheless,
standardization focused on conventional workflow systems. In
an Internet-based medical environment with high security standards communication
is strongly restricted and conventional systems fail to deliver.
This paper proposes a modeling process for medical Web services. The
IHE patient administration process flow serves as a well defined example.
Furthermore, the paper defines requirements of a Web service based middleware
for the execution of medical e-services by investigating currently
relevantWeb service protocols. The technique should enable building medical
applications for Internet-based workflow execution. Finally, Biztalk
2004 is used to evaluate the implementation of the analyzed sample functionality.
