Topic: Observations: "other, please specify"

Josh Mandel (Nov 21 2016 at 22:52):

Does anybody have best practices for mapping LOINC answer lists that include "other, please specify" into a FHIR Observation? For example, http://r.details.loinc.org/AnswerList/LL2654-3.html — the question is where you'd put the specified "other" answer. Some possibilities include:

a .text on the same CodeableConcept
a second Coding in the same CodeableConcept
a .component
a .related
an extension

... but none of these sounds ideal, and I feel like I may be reinventing the wheel

Eric Haas (Nov 21 2016 at 22:59):

I'd narrow to my first choice would be .text
"... or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source."
second choice an"Other" .extension

.text yes

Josh Mandel (Nov 22 2016 at 05:34):

So you'd provide the LOINC Answer code for "Other" in s Coding, and supplied value in CodeableConcept.text?

Grahame Grieve (Nov 22 2016 at 06:12):

yes

Josh Mandel (Nov 22 2016 at 13:45):

OK. For anyone following along, that's something like:

{
  "resourceType": "Observation",
  "code": {
    "coding": [{
      "system": "http://loinc.org",
      "code": "74076-1",
      "display": "Medication or substance involved"
    }]
  },
  "valueCodeableConcept": {
    "coding": [{
      "system": "http://loinc.org",
      "code": " LA20343-2",
      "display": "Other substance: PLEASE SPECIFY"
    }],
    "text": "Other substance: Blue pills I found under my couch"
  }
}

Thanks, I was just wondering how to model a similar case. Since this is such a common use case, might it be an idea to Put @Josh Mandel 's example straight in http://build.fhir.org/observation.html? (Though I think "text": "Other: Blue pills I found under my couch" might be better.)

Robert McClure (Nov 22 2016 at 16:45):

FWIW, I agree!
