In order to take the full advantage of telemedicine applications, they must seamlessly be integrated into healthcare services and their information systems (e.g. HIS, POS, RIS). In our approach an HL7/XML-based integration module is used 1) to exchange documents with information systems; 2) to generate and administer documents internally; 3) to present documents. The module fills in pre-defined CDA-conforming XML templates with data from HL7 V2 messages. The approach is first applied to the teleconsultation service EST in the project ENDOTEL.
