Including reference range in archetypes

Hi Dileep,

This is a common scenario, that right now is mostly handled in application
code.

My understanding of normal_range/reference_ranges (part of the quantity
model) is that these are intended to carry the normal ranges that apply to
a biological observation such as lab_test or perhaps imaging_ exam, rather
than (as in your case) a sort of rule that is applied to caclulate or
categorise risk.

The most high profile comparable example I know of , is the NEWS score.

Archetype at NEWS (UK RCP), Published archetype [Internet]. openEHR
Foundation, openEHR Clinical Knowledge Manager [cited: 2017-04-13].
Available from: http://openehr.org/ckm/#showArchetype_1013.1.2423

Rules at https://www.mdcalc.com/national-early-warning-score-news

I would expect a UI to colour-code each component in a similar fashion, to
indicate potential risk.

You might want to explore GDL, which is an extension to openEHR that acts
as a glue layer between archetypes and those sort of rules.

http://www.openehr.org/releases/CDS/latest/docs/GDL/GDL.html

There is also some interest in folding aspects of GDL inside archetypes as
part of the 'rules' aspect of ADL. One of the barriers to getting this
working at scale, is deciding what 'vendor-neutral' rules definition
language to use. Not everyone is a fan of javascript but I do see some
potential in this space given its ubiquity in the market.

I'm not sure I have answered your question!!

Regards,

Ian
