For those in the community wondering what the US does for 'clinical modelling', here is  one effort that is currently running - [USCDI](https://www.healthit.gov/isa/united-states-core-data-interoperability-uscdi#uscdi-v2), under the auspices of the US Gov ISA (Interoperability Standards Advisory).

It varies between the basic (what we would consider 'reference model') e.g. [Encounter information](https://www.healthit.gov/isa/uscdi-data-class/encounter-information), to various kinds of [clinical notes](https://www.healthit.gov/isa/uscdi-data-class/clinical-notes), [patient demographics](https://www.healthit.gov/isa/uscdi-data-class/patient-demographics), and a few clinical items (e.g. [allergy/intolerance](https://www.healthit.gov/isa/uscdi-data-class/allergies-and-intolerances)).

I would guess it has no more than about 5% of the structured data points of openEHR archetypes, but it's always worth knowing how modelling is happening elsewhere.
