Clinical building blocs & allergies

Hi,

In the allergy models document, I didn't see the Clinical Building Blocks (CBB) information model for allergies. NICTIZ has made a CBB model for the capture of clinical information around allergies/intolerences. The CBBs have been adopted as standard in Belgium where the e-Health authority plans to make their use mandatory for the transmission of this type of clinical information by the hospitals to the official state registries. https://www.healthdata.be/doc/cbb/index.php5/The_Clinical_Building_Blocks_%28Belgian_version%29

It's not that easy to match the meanings captured in the CBB format and what is found in precoordinated SCT concepts. Does anyone have experience with the implementation of the CBBs or a similiarly "dissected" model of allergy/intolerence capture separating the reaction type from the substance and the manifestation of the allergy and on how to reconcile identical information recorded with precoordinated concepts "allergy to x" with info that would be recorded with the CBB so the two would be logically equivalent?

Thx.
