Ian,
Your suggestion that a GUI be closely wedded to the EHR makes me
shiver. How about a design-pattern approach of having a decoupled
program layer that interacts with the data?
This layer can be accessible by an (independent) GUI layer.
I agree with your need for a common set of fields. How about a library
of abstract classes to match your data?

That's what I was thinking of when Horst made his suggestion. I'd love it.
I would never be blamed because of my choice of program (although I haven't
had any for more than a year)
One of the things I've learnt from trying to write an EHR is that the GUI and
the backend are inevitably wedded fairly closely in term of behaviour. You
can move things around, change fonts, colour etc. very easily, but to
implement a particular workflow on the GUI, you need a matching database
structure.
This is also why a 'common set of fields' to make EHR data portable is very
hard, unless you make it very simple, and then the imported data won't be
as 'rich' as the EHRs own data. For example, you won't be able to do
automatic repeats scripts from the old data, as it's just a free
string "Amoxil 500mg tabs" which the new EHR can't make sense of. You can
read it though, so it's still useful.
This is not absolute, I think it is possible to have the two interfaces
demonstrated by Richard and Horst talk to the same backend, (and an MD-style
one as 'lowest comon denominator') however it would need very careful
thought, and there would be limits, certain areas were all the clients would
have the same or similar behaviour.
