Re LOINC adoption in US vs READ codes: I can understand why, it is more
logical/comprehensive/systematic...you name it...however LOINC is not
perfect at all: eg it is not object oriented at present. But at risk of
misrepresenting history, I understood that one of the influences the
European/UK views brought to the SNOMED collaboration was the object
orientation that SNOMED CT adopted. A similar influence may come about with
more collaboration in this area....
I'll check out OpenEHR

Just a little clarification - my understanding was that the Read codes for
tests were offered to SNOMED but the US insisted in going with LOINC and
hence initially isolating Pathology.
In the end there will be one global code scheme - complex I know but
necessary. OpenEHR is worth a view as it's based on open architecture and is
object orientated. Problems with early code systems were that they were too
rigid and lacked the ability to deal with the rapidly changing world. It's
noteworthy that SNOMED is beginning to emerge into the new world of open
standards - see also Microsofts open source moves with the common user
interface.
In the new world it pays more to collaborate than compete - sadly we are
still paying the price for previously mis-guided attempts to corner the
market in codes.
As to who's in charge of UK pathology coding - I'd love to find out.

Hi Arden,
I think this call for a collaborative effort is very commendable. There is
just one problem with it: the US have decided a few years ago that they are
adopting the LOINC database for the names/codes of laboratory tests and
other clinical observations, and whoever in the UK is in charge of these
things seem to view it with antipathy or at least indifference. As I
understand it there is collaboration with SNOMED CT so that the domains will
be complementary. Several other countries in Europe has also agreed to adopt
the standard.
http://www.clinchem.org/cgi/content/full/49/4/624
Nobody is saying it is yet the complete package, but it is a damn sight more
comprehensive and systematic with potential for improvement (eg in
describing ordering panels) than anything else I have seen. The issue of
developing a single framework for standard units of measurement is one which
should also tie in to that (and in the US I guess it does??).
For my part I have never understood why we in the UK cannot see the sense of
joining the collaborative and influencing the changes one might want to see
from the UK perspective, just like the situation was with READ codes (UK)
and SNOMED RT (US). Then the NHS and College of American Pathologists joined
hands and SNOMED CT hasn't looked back since. Instead there is constantly
new little initiatives here in the UK bubbling up under various
organizations uncluding the Southern cluster in NPfIT which seems keeps
re-inventing the wheel (yawn!)
The point I am making is: if the UK is not even part of the broader
collaborative of agreeing names and codes for test results, then the issue
of agreement on SI units is almost moot, as there is unlikely to be any
universal exhange standard.
I would be very interested if someone could enlighten me why this is
happening (or not happening!)

I would like to urge that the UK clinical laboratorians dvelop a
collaborative effort with those in the US with respect to the common units
and their representations (whether in messages or in data structures
such as the EHR). The IFCC/IUPAC SI represerntations are those recommended
both by national and international groups. The educational challenge for
the health professional (useers and producers of measurments/observations)
has been a majo one over the 16 years that work of the US with the EU
CEN TC 251 groups has been pursued. Much more could and should be done
collbaoraively and synergistically. AACC LISMID Chair Al Jekelis is a key
contact and he is working with LISMID memeber pam Banning on a
terminology program for the AACC 2008 Annual meeting in July in Washington
DC. There is still time to develop a joint effort with ACB to address this
specific challenge and have useful information by the time of that
presentation. I invite those interested to contact these individuals on
this subject.
