Description
I agree, it's an useless source of mistakes.
So:
- cardinalities of manufacturedMaterial/ingredient/quantity/numerator and manufacturedMaterial/ingredient/quantity/denominator have been set to 1...1 and nullFlavors are disallowed.
- cardinalities of @value and @unit are not modified (1...1).

Description
Note: in CH FHIR, cardinalities 1...1 were chosen for numerator AND denominator, see  CH.FHIR.IG.CH-EMED\CH EMED Ratio with units - FHIR v4.0.1
Reason: omittance of units or interpretation as "if absent it is the unit of medication" is too unclear and dangerous, see example of conversion at Projectathon 2020
Therefore, I would leave the denominator as it is now.

denominator: @unit was set to required (1...1) but should be optional (0...1) -> issue reopened

Description

After discussion with Stéphane, we are proposing the following changes to the ingredient quantity:

The ingredient quantity (pharm:ingredient/pharm:quantity) is represented as a ratio, it does not make sense to only have the numerator or the denominator and the IHE PRE profile does not explain how to process an incomplete ratio. The cardinalities of hl7:numerator and hl7:denominator should then be set to 1…1; if it's unknown, the whole pharm:quantity can be omitted.

To improve the template, the following changes can also be made:

  • In hl7:numerator:
  • The @value attribute is required (1…1) and is a strictly positive number (integer?).
  • The @unit attribute is required (1…1) and can be restricted to a specific value set (UCUM or UnitsOfPresentation?).
  • The null flavor is forbidden.
  • In hl7:denominator:
  • The @value attribute is required (1…1) and is a strictly positive number (integer?).
  • The @unit attribute is optional (0…1) and can be restricted to a specific value set (UCUM or UnitsOfPresentation?). If absent, the denominator unit is the unit of medication.
  • The null flavor is forbidden.
      What do you think?
