So if it is serum sodium, the range will still depend on all of these things, and cannot be archetyped. The intention is not to use archetypes to standardise these values, but to provide a place for labs to put the specific normal range values that applied for each analyte, for the particular patient, and remembering that each lab has slightly different instrument settings.
Probably what you are looking for is the normal range reference data - like what you see in a pathology book, or what any physician knows for all of the main vital signs and other measurable things. We consider this to be reference information, like terminology, but for quantified values. While much of it is published in paper form, as far as I know there is no recognised way to represent quantitative range data in a standard computable form (i.e. in the way that you can get Snomed or ICD10 in a computable format). This is needed. But archetypes are not the place to standardise this - archetypes are about defining content structures, not domain reference knowledge. - thomas beale > Or should a decission support module be responsible for this? > > thank you > > _______________________________________________ > openEHR-technical mailing list > openEHR-technical at openehr.org > http://www.chime.ucl.ac.uk/mailman/listinfo/openehr-technical > > > -- ___________________________________________________________________________________ CTO Ocean Informatics (http://www.OceanInformatics.biz) Research Fellow, University College London (http://www.chime.ucl.ac.uk) Chair Architectural Review Board, openEHR (http://www.openEHR.org)
