Topic: Best practice for answerValueSet + enableWhen

Vadim Peretokin (Nov 22 2021 at 16:52):

Q1 is a #choice with an answerValueSet, Q2 needs an enableWhen on Q1. Is it best practice to use a enableWhen.answerString or enableWhen.Coding?

Lloyd McKenzie (Nov 22 2021 at 18:06):

Coding, if you're matching on coded values. In theory you could have an enableWhen based on a string, but given that equality is going to consider differences in case, whitespace, spelling, accents, punctuation, etc. as significant, using enableWhen with 'string' is pretty unwise

Got it thanks. I take it it's normal the publisher just renders Enable When: and doesn't actually show the invariant when I have this:

      "enableWhen" : [
        {
          "question" : "ComorbiditiesSACQ",
          "operator" : "=",
          "answerCoding" : {
            "system" : "http://snomed.info/sct",
            "code" : "56265001"
          }
        }

That expression looks right to me.

Thanks for checking!
