Topic: Ratio + Comparator

Glory Kim (Feb 04 2020 at 02:03):

I'm curious about how the the Ratio Data type (https://www.hl7.org/fhir/datatypes.html#Ratio) is operates when the Quantity in the numerator/denominator has a comparator.

In the case that the numerator is a quantity with a value of
  const qtyNumerator = {
    value: 0,
    comparator: "<=",
    unit: "mg",
    system: "abc",
    code: "MG"
  };

  const qtyDenominator = {
    value: 3,
    comparator: "<=",
    unit: "ml",
    system: "abc",
    code: "ML"
  };

would the ratio be "0 mg / 3ml" or should the comparators be included to display "<= 0mg / <= 3ml" ?

the denominator should not allow a comparator

can you create a task to make a rule about that?

Will do - thanks

I had wondered about that. (>=10)/(>=20) as a ratio makes no sense. Woukd it be enough to just redefine the denominator as a SimpleQuantity, as SQs don't allow comparators.

possibly, yes
