PCEHR-InformationArchitecture

PCEHR Information Architecture The fact that it is to be updated by Templates based around CDA Technology (as different to CDA Principles, HL7 V3 Principles or RIM) means that the information will have severe limitations aroung searching, retrieval and identification of what being sought.

The document obviously acknowledges that there is likely to need to be some level of flexibly in the beginning until processes are bedded down. This is probably a reasonable approach in terms of getting an appropriate level of buy in. However, that said, it is very difficult to unscramble the proverbial egg once there is a variety of customisation out there. Maybe this process needs a little more consideration has to how non-standardisation is going to be phased once in place. I suspect that this is much easier said than done. I would also like to see more detail on how the PCEHR will integrate with existing systems both in primary health and in the hospital sector. Who will determine and how will data be shared between these systems. Is their duplication of effort involved? I am aware that the Victorian government is about to look at electronic medical records for the public hospital sector; I would hate to think that think occurs in isolation of, PCEHR and vice versa.

DM Right now there is no detail and the Standards to be used have not been determined. We need to be very clear the PCEHR is intended to be a secondary system which aggregates data from actual live systems used by providers. Not also the linking of all this up is said not to be done by the DoHA CIO before 2020. See my blog for links.
