If I generate an Observation that contains a vital sign but it is following the PHD profile, am I required to have a category element? In particular populated with the vital signs code from
http://terminology.hl7.org/CodeSystem/observation-category?
Grahame Grieve (Nov 11 2018 at 22:46):
yes it must, according to the spec
Brian Reinhold (Nov 11 2018 at 22:48):
yes it must, according to the spec
I knew it had to have the Loinc code but the other requirements of the Vital Sign profile seem quite heavy. Does it actually mean I have to SATISFY the vital signs profile?
Grahame Grieve (Nov 11 2018 at 22:54):
what's heavy about it?

If I have to implement everything else required in the Vital Signs profile (in addition to the PHD observation profiles) even though that is not the intent.

what's not whose intent? What's heavy about it?

Implementing a profile requires populating certain elements with certain fields. To satisfy the vital signs profile I have to populate elements I don't populate in the PHD Observation profiles and make additional entries in the meta profile and code elements, for example.
Grahame Grieve (Nov 11 2018 at 22:59):
yes, that's the intent. Here's the rules:
- a status
- a category code of 'vital-signs'
- a "magic value" which tells you what is being measured
- a patient
- a time indicating when the measurement was taken
- a numeric result value and standard UCUM unit which is taken from the Unit Code column in the table below. note: if there is no numeric result then you have to supply a reason

nothing there about meta profile....
Brian Reinhold (Nov 11 2018 at 23:52):
yes, that's the intent. Here's the rules:
* a status
* a category code of 'vital-signs'
* a "magic value" which tells you what is being measured
* a patient
* a time indicating when the measurement was taken
* a numeric result value and standard UCUM unit which is taken from the Unit Code column in the table below. note: if there is no numeric result then you have to supply a reason
Well, that's not too bad then. THe PHD profile has everything but the category. The additional Loinc code is already required if a vital sign. That we knew we had to do. So the only extra burden is the category.
Grahame Grieve (Nov 11 2018 at 23:58):
so I think that's reasonable - the category has real useful functionality
