This one I presented at the HINZ conference 7-9 Nov 2012 at Rotorua, New Zealand.
As we are moving into new paradigms of care, sharing of health information becomes crucial. We need new systems and more interconnectivity to support this. The regional approach to eHealth solutions in New Zealand hinges on establishing trusted and interoperable systems. The Interoperability Reference Architecture is a first step towards providing overall principles and standards to reach this goal. A core group from the Sector Architects Group was formed and prepared the first draft of this document. After initial internal feedback it went through wider consultation – including public. Good feedback was received, including international. It then went through formal HISO processes and was approved as a national interim standard. The Reference Architecture comprises three pillars which define: 1) XDS based access to clinical data repositories, 2) a common content model underpinned by CCR and openEHR Archetypes to which all health information exchange should conform, and 3) use of CDA as common currency for payload. A trial implementation is yet to be conducted, however we used the Content Model to align ePrescribing data model with the Australian model in order to validate the methodology. The Reference Architecture will provide an incremental step-by-step implementation approach to interoperability and thus minimise risk.
