The lab results in BC CA include the HL7 message segment OBR 004
"Universal Service ID" of the form "Test code^Test name" for example
As an aside: note how code isn't a code but rather an arbitrary
abbreviation. I'll consider adding a field "abbreviation" to
clin.test_type to differentiate codes from pseudocodes. The "code"
can still be pre-set with the abbreviation if so desired.
Wait, actually, that's what "test_type_unified" is for.
The thing to note is that a *single test code* can represent
*multiple results* that will be received.
That's the difference in meaning: test as in "one measurement" vs
test as in "a proceeding upon a material to establish data about it".
IOW this OBR can be followed, in the same message, by multiple OBX
records for example
I expect the test code would be useful for grouping the display of
results within GNUmed, think also "Liver ennzymes" or else
"Hematology Panel" which would include Hemoglobin, White Blood cell
count, platelets and there are also related tests like the white
blood cell differential and peripheral blood film ("smear") which
could be usefully grouped together under the broader classifier which
is carried in the OBR 024 "Diagnostic Service Section" (Laboratory
Section Codes) for example "HAEM", "CHEM", "MICRO".
Correct. Liz did some work on (clinical) profiles back in the days.
I gather there is already a recognition of this but maybe just not
yet provision in the schema, because under the schema specification
for the table clin.test_type_unified there is a disclaimer
this is not intended to be used for aggregating semantically
different test types into "profiles"
So we are probably talking here about these same profiles.
Even though I understand it will take some time for the display
widgets to catch up with the potential display options, I am
reluctant to "lose" data that [may be] ... impossible to repopulate.
That is the single best argument you could have made for inclusion
of test_panel :-)
Maybe this means we need, in clin.test_type
Will put it on the TODO even for the first iteration.
One basic design paradigm in GNUmed is: Never lose patient data. No
release will happen in which we *know* about data loss issues.
