Thanks. I agree that things are moving ahead. I wish we could remove some
of the animosity (maybe I am reading it worng) towards HL7 (not from you),
and close the gap between the two efforts.
best Regards.

*Ed,
I should stress that these are pure openEHR systems; systems based on
archetypes of some kind include Systematic (SSE) in Aarhus, Denmark, and
Obstet in Australia. Both companies have expressed serious interest in
'going official', and I happen to know that their architectures are
sufficiently close to the archetype / template idea that it is feasible.
I dont have any numbers on EHRs in these systems but I would expect in
the hundreds of thousands, based on the catchment areas they serve.
Although I said at the beginning that I don't think it is that useful a
statistic, it's not a bad brut measure of uptake, so let's see if we can
gather some better numbers, for interest's sake.
One reason for success of at least our own EHR server (Ocean
Informatics) is that its performance is good - sub-0.5 second for
everything so far, with a typical concurrent load equivalent to about a
1,000 bed hospital. I don't yet have performance numbers for harder
population queries, but mundane population queries across 10,000 -
250,000 EHRs are fast.
This isn't the place to advertise, but I think it is reasonable to at
least allow the community to know that real performance is indeed
possible and feasible to implement in openEHR. If others agree, it may
be the time to do a bit of a poll and start putting harder data on the
'who is using it' webpage.
