Dave,
the solution to this situation is not yet 100% clear in ADL2 (it is in
ADL1.4, as others have described). We are trying to define a cleaner way
to represent it in ADL2, but I'm still not clear on the requirements. It
appears that the scenario you have is that since SNOMED CT, READ and
CTV3 are extant in the UK, coding should be allowed using any of those,
but not by other means.
Does this apply across the whole HSCIC model library? Or do you want
some more fine-grained control, e.g.:
* do you want to designate certain terminologies for specific
templates ? E.g. template A can only use SCT, but template B can use
any of the three?
* do you need to say on a node-by-node basis in a single template,
e.g. this node must be coded by SCT, but this other node by say
SCT-or-READ, and this third node, any of the 3 are allowed?
If others can clarify requirements in this area as well, it would be
very helpful.
See here in the ADL2 draft spec
<http://www.openehr.org/releases/AM/latest/docs/ADL2/ADL2.html#_terminology_integration>for
current thinking on this.
thanks

I have a modelling issue where I’m trying to bind a single data point
or an archetype to a choice of terminology & code systems.
The actual use case is that I’m modelling a new-born hips examination,
and the result may be given as either a SNOMED CT concept, a Read 2
code or a CTV3 code (for those unfamiliar with Read 2 & CTV3, they are
code systems used (mostly) in primary care in the UK). In the actual
instance, each code/concept will have a code system identifier to
distinguish the actual code system used
For example, a result of “no abnormalities and no risk factors” can be
represented as either
*SNOMED CT*
*Read2*
*CTV3*
ID
FSN
ID
Term
ID
Term
985701000000100
Newborn and Infant Physical Examination Screening Programme, hip
examination done, no abnormality and no risk factor
9OqJ1
NIPE hip, no abnor&no rsk fctr
XadAN
NIPE hip, no abnor&no rsk fctr
In the modelling tools I see you can have a choice, but I can’t see
how the choice supports multiple terminologies. I see that it does
support a choice of a terminology & Free text.
Is there a “standard” way of saying a data point may be represented by
one of 3 terminologies/codes systems? Or is this something the tooling
deliberately stops you doing?
Thanks in advance
