Treatment identifier not always available in PML Observation #66

Open qligier opened 4 months ago

In an Observation, only one reference is allowed to MTP, PRE or DIS entry and document identifiers. The targeted entry is the one from the reference. It's perfectly clear that way in a PADV, but has one drawback: in a PML, it's the only entry that may not have the treatment info (if it targets a PRE or DIS). I'm not sure how to nicely solve that, since CH-EMED prevents having two references at the same time (MTP + PRE or DIS).

But the medication request changed resource has the treatment plan extension. In a PML, the observation (CHANGE) itself might not contain the treatment plan reference, but resolving the changed resource would allow you to get the treatment plan reference. Is there a use case for which this would not be enough?
