Hi, since Observation.bodySite is 0…1, how would you represent “numbness in left arm and right hand”? Use two separate observations?
Yes. (Each location might have other differing characteristics too, such as severity, duration, onset, etc.)
yes, but they also might not.
Sure, but the model needs to allow for that. I guess the alternative would be to use the extension to point to BodyStructure and have the BodyStructure describe the full area.
