Actually, my e-mail was more of a hello. I didn't think you were giving
Duke a hard time. Our approach is similiar to what you are doing, however,
we are focusing at the atomic level. Building from that is simply a
construct. It will be i nteresting to find out what stays packaged and
what breaks out. My approach is to make the data independent of the
construction. If the data element is never dealth with without thw full
structure we will keep it packaged; else not. I think we let our
experiences influence how we move forward. But as you know, I try to pay
attention to what everyone is doin g so I can use the best approaches.

Hi Ed,
I didn't say it was bad (it is probably very good) - I said it was 'fixed'.
Like CCR - which as far as I understand is very good domain modelling - but
also pretty fixed. The debate here is about 'how' not 'what'. If I was
working on the vMR in HL7 right now, the first thing I would do would be to
copy exactly the content you have modelled in the diagram I referred to -
in to archetypes and templates. Then I would get for free:
the ability to change it with no changes to any reference model
(information remains valid)
the ability to add completely new things, also without requiring any
changes in the underlying information model
the ability to query everything in a generic fashion using queries
based directly on the domain models
This argument is the same as with all the *MIMs in HL7 - as a technology I
don't think they work, but I don't question their content (in most cases I
am not competent to do that). I would really love the opportunity to show
you how nice this model could be if modelled in archetypes in an openEHR
system. You would get just what you want with much greater flexibility.
Please don't think I would seriously question Duke's clinical work. I just
think you are working with the wrong IT;-)

Hi Thomas,
I am now back at Duke in a full time capacity. The work within HL7
is
being lead by Ken Kawamoto from Duke, a colleague of mine. Duke has
one fo
the best clinical research enterprises in the world - the Duke
Clinical
Research Institute and the new Duke Translational Medical Institute,
where
the Duke Center for Health Informatics is based. We have
asignificant
weffort committed to defining detailed clinical content. I'd say
let's
postpone the decision (as ever) for a couple of years and see if we
are as
bad as you think.
Actullay, we have an effort similar to Evelyn's and look forward to
working
with her.
