Greg, Interfacing with existing systems using messaging such as HL7 is something I have been doing for some time now and we have a considerable amount of infrastructure to make it happen. Ocean Informatics was involved in an Interoperability Demonstration (similar to the IHE Demonstration at HIMMS) at the recent MedInfo international health informatics conference in Brisbane. We demonstrated accepting HL7 V2 lab, ADT and referral messages from other vendor system and stored them as openEHR compositions using both base and specialised archetypes. The process involved building a template of those archetypes for each message type and mapping the HL7 into those templates. We also demonstrated converting an openEHR composition directly committed in an openEHR repository to HL7 CDA. The original creation of the composition utilised a template but the actual conversion to CDA simply utilised the knowledge in the archetype models to understand and develop the transformation to the associated HL7 clinical statements within the CDA. This CDA document was then submitted to another vendors IHE XDS repository. This same process can be used to create HL7 v2 messages or any other format you wish.
