multiple questions: database, archetypes, templates

Personally I suspect of more immediate value is not necessarily the
exchange of interoperable data but perhaps if an organization defined
all their clinical documentation in terms of archetypes and templates,
then wanted to switch EHR’s, they would not lose all that ‘build’ work
which would save significant cost in implementation time of the second
EHR.

True! And interoperable data exchange (in terms of full semantic interoperability rather than just freetaxt plus coded diagnoses) will follow from that IF THERE IS A USE CASE. The openEHR framework provides the ability (can cover the whole spectrum: no, partial, full semantic interoperability), the clincians and other stakeholder have to figure out where it is useful, realistic, wanted, payable… and align their archetypes +/- templates accordingly. There probably won’t be full semantic interoperability on an national or even international level besides maybe emergency data. But it can be very useful in regional health networks. As I said openEHR provides the technology that can make it possible, the users (clinicians) have to figure out where they want it and reach consensus. Thus, openEHR could make it possible for interoperability to evolve organically.

Hi Thomas,

Back to the data captured based on a archetype… part of the data was specified by the
archetype kind (say, INSTRUCTION, EVALUATION or whatever CARE_ENTRY), and part of the
data comes from the archetype specification itself…

I was just wondering if that doesn’t naturally imply a relational approach to the RM, and a XML-BLOB-approach
the the rest of the data captured by an archetype…

all data captured by the use of an archetype is defined by the reference model - there is only reference model data.
Archetypes just define legal arrangements of said data.

XML blobbing is indeed a fairly typical approach to object data like that found in openEHR, and can be done at different levels of granularity, as described in the link below.

Ok, I guess that this is the key part that I did’nt understand/see til now!

Thanks for enlightening me on this…
