Hi,
We have an example of an Observation that should contain multiple body sites. The Observation describes the tumor invasion into multiple different organs that are adjacent to the tumor.
Can this be represented in a single observation with multiple codings, with each for for a particular organ that the tumor is invading (e.g. Tumor Invasion into Adjacent Organs: Kidney, Liver, Spleen. )???
Thanks,
Joel, @Alex Goel

BodyStructure can give you more information about where the tumor was found. The Specimen itself would point to the tumor as the site.

@Lloyd McKenzie Thanks Lloyd, but the issue is that we have multiple bodySites that we want in a single Observation pasted image is this allowed?
Lloyd McKenzie (Aug 28 2019 at 18:10):
No. All codings need to refer to the same concept.
Lloyd McKenzie (Aug 28 2019 at 18:13):
The fact that the tumor has invaded multiple organs would be observations about the tumor. If you were doing radiology imaging, your body site would simply be upper torso or something like that. If you were doing a specimen, then your specimen would be drawn either from 'tumor' or from a specific organ that the tumor had invaded. You wouldn't typically have a specimen that was drawn from both lung and liver, I don't think
Alex Goel (Aug 28 2019 at 18:28):
@Lloyd McKenzie OK that works! For our example the bodySite can be adrenal gland, then then tumor invasion sites can be components of Observation. The specimen then has a specific bodySite it came from, but descriptive observation of what sites it is invading.
Lloyd McKenzie (Aug 28 2019 at 18:31):
They might not even be components - components are generally things not interpretable on their own. An assertion that "tumor invades lung" can be understood independently from "tumor invades liver". Both Observations would be made about the same BodyStructure (which represents the tumor).

That makes sense to use separate observations in some use cases
