@Eric Haas do you know of any work around representing blood group and Rh Status in Observation?

Grahame Grieve (Mar 01 2018 at 02:12):

this would be a good example to add, right?

Grahame Grieve (Mar 01 2018 at 02:19):

how about this:

Grahame Grieve (Mar 01 2018 at 02:19):

{
  "resourceType" : "Observation",
  "subject" : {
    "reference" : "Patient/<patient-id>"
  },
  "code" : [
    "coding" : [{
      "system" : "http://loinc.org",
      "code" : "34532-2"
    }],
    "text" : "Blood Group Panel"
  ],
  "component" : [{
    "code" : [
      "coding" : [{
        "system" : "http://loinc.org",
        "code" : "883-9"
      }],
    "text" : "Blood Group"
    ],
    "valueString" : "<A.ABO>"
  },{
    "code" : [
      "coding" : [{
        "system" : "http://loinc.org",
        "code" : "10331-7"
      }],
    "text" : "Rh Status"
    ],
    "valueString" : "<A.Rh>"
  }]
}

Eric Haas (Mar 01 2018 at 02:26):

nope

Grahame Grieve (Mar 01 2018 at 02:27):

ok why not

Eric Haas (Mar 01 2018 at 02:32):

nope to the first question I created this a while back...

Grahame Grieve (Mar 01 2018 at 02:36):

ok. so I made a few mistakes, so this:

Grahame Grieve (Mar 01 2018 at 02:36):

{
  "resourceType" : "Observation",
  "status" : "final",
  "subject" : {
    "reference" : "Patient/<patient-id>"
  },
  "code" : [
    "coding" : [{
      "system" : "http://loinc.org",
      "code" : "34532-2"
    }],
    "text" : "Blood Group Panel"
  ],
  "component" : [{
    "code" : {
      "coding" : [{
        "system" : "http://loinc.org",
        "code" : "883-9"
      }],
    "text" : "Blood Group"
    },
    "valueString" : "<A.ABO>"
  },{
    "code" : {
      "coding" : [{
        "system" : "http://loinc.org",
        "code" : "10331-7"
      }],
    "text" : "Rh Status"
    },
    "valueString" : "<A.Rh>"
  }]
}

Eric Haas (Mar 01 2018 at 02:40):

Eric Haas (Mar 01 2018 at 02:41):

to which this kind of aligns. never got the blood typing panel though just noodling a bit

Grahame Grieve (Mar 01 2018 at 02:49):

k. so there's a question about the panel/component thing. And also which data type to use. LOINC is silent about this

Eric Haas (Mar 01 2018 at 04:03):

They are stand alone measures and I think should be individual Observations.

Rob Hausam (Mar 01 2018 at 16:23):

I agree with Eric that these should be individual observations - this is a panel, and the individual observations can be used independently.

Grahame Grieve (Mar 01 2018 at 21:01):

and which data type?

Rob Hausam (Mar 01 2018 at 21:22):

any reason it shouldn't be valueCodeableConcept?

Grahame Grieve (Mar 01 2018 at 21:37):

is there a code system suitable for use? Other than SNOMED?

Rob Hausam (Mar 01 2018 at 21:49):

there may be LOINC answers for it - I haven't looked to be sure
