I am trying to map a relationship code for 21-day cycle for 6 cycles with or without subsequent radiation, I dont see any ActionRelationshipType that match this "with or without subsequent radiation"?
Jose Costa Teixeira (Jul 30 2019 at 13:59):
what resource are you using for the cycle?
Jefferson (Jul 30 2019 at 14:03):
ActivityDefinition
<relationship value="concurrent-with-end">
<extension url="/radiationTherapyRelationship">
<valueCode value="with or without subsequent radiation" />
</extension>
</relationship>
Jose Costa Teixeira (Jul 30 2019 at 14:11):
if you just want to indicate the "with or without subsequent radiation" perhaps such an extension is ok (i am not so sure but can't pinpoint why).
if you want to consider that subsequent radiation as an activity, and be able to describe it ... then I think it may be interesting to look at PlanDefinition?
Jefferson (Jul 30 2019 at 14:15):
Ok but what if the the codes that are define will not fit? http://hl7.org/fhir/codesystem-action-relationship-type.html
Lloyd McKenzie (Jul 30 2019 at 14:42):
So radiation may or may not be going on in parallel with the 6 21-day cycles? In that case I'd have an optional action for radiation therapy and define it as happening in parallel with the medication activity
Lloyd McKenzie (Jul 30 2019 at 14:42):
Putting an extension inside the relationship would be rather odd - the extension is defining the type of relationship, not what the relationship is to (that's handled by the mandatory activity id)
Jefferson (Jul 30 2019 at 16:16):
So you wouldn't use the extension just use a different type of relationship?
Lloyd McKenzie (Jul 30 2019 at 16:18):
"Giving radiation" should be expressed as an activity. The relationship is that it's happening in parallel (so relationship.type would be 'concurrent').
Lloyd McKenzie (Jul 30 2019 at 16:19):
requiredBehavior on the radiation would be 'could' (to indicate that that piece is optional)
Jefferson (Jul 30 2019 at 16:21):
Great Thanks @Lloyd McKenzie
