I agree Ian - though they are always triggers in reality. Australia made more progress on Lipids when it changed labs from reporting actual norms to target norms. Suddenly everyone had high cholesterols and down they have come!

I have suggested that if Pablo is trying to set trigger conditions e;g a series of BPs over a particular level, then this properly belongs in the guideline/pathway space, rather than as ref ranges?

A Quantity data type has a normal range and other reference ranges built in. We do not set the reference ranges in archetypes as these vary and archetypes are the absolute statement about things (what could possibly be true ever, anywhere). So it is in the form or data that you will get access to the reference range. You could set it in a template (not possible in our tools as yet). Generally the reference ranges come with the results from the lab or a dynamic depending on gender, age etc. I hope this is helpful - have a look at the data type specs for clarification. The UML is at: http://www.openehr.org/uml/release-1.0.1/Browsable/_9_0_76d0249_110959933787 7_94556_1510Report.html You will see an optional normal_range and 0..* other reference ranges as part of a root abstract class DV_ORDERED Cheers, Sam From: [email protected] [mailto:openehr-technical-bounces at openehr.org] On Behalf Of pablo pazos Sent: Tuesday, 13 October 2009 8:02 AM To: openehr-clinical at openehr.org; openehr-technical at openehr.org Subject: Modeling reference ranges Hi, I'm playing around with archetypes trying to model an observation and its reference ranges, I mean something like "blood pressure" and some range to define what is "hypertension", but I can't found an archetype that defines a reference range for an observation. Any one has experience in modeling something like this? An archetype is the correct place to define a reference range for an observation value? Any ideas? Thak you!
