@Bryn Rhodes what should we do with GF#6255?
Bryn Rhodes (Feb 15 2018 at 22:16):
@Grahame Grieve on GF#6255, I believe the use case that drove that tracker ended up resolving a different way. For the Chemotherapy regimen representation, we use the timing-daysOfCycle extension, and for offset from some action, we use the relatedAction element in PlanDefinition or RequestGroup to specify the source of the offset. @Lloyd McKenzie , do you have any additional unmet use cases that would require an extension as described in this tracker?
Grahame Grieve (Feb 15 2018 at 22:19):
that's a much better way to solve this problem.
Lloyd McKenzie (Feb 15 2018 at 22:40):
Yes. I need it in events, not definitions. So "This blood pressure occurred on day 10 of the study" or "This adverse event occurred 2 weeks after administration of the test substance"
Lloyd McKenzie (Feb 15 2018 at 22:41):
Clinical trials reporting have the notion of capturing offsets from day of study and from start of treatment on a whole bunch of different things. (And when reporting these may be sent instead of or in addition to actual dateTimes)
Lloyd McKenzie (Feb 15 2018 at 22:42):
Purpose is to make it easier to link when events actually occurred to when they were supposed to occur (events are scheduled based on study day/study day range) as well as relating things to start of treatment to help evaluate causation.
Grahame Grieve (Feb 15 2018 at 22:52):
I'm not sure which side you are speaking on here
Lloyd McKenzie (Feb 15 2018 at 23:59):
I'm saying that relatedAction in PlanDefinition and RequestGroup doesn't help my usecase
Grahame Grieve (Feb 16 2018 at 00:11):
would a similar approach solve it?
Lloyd McKenzie (Feb 16 2018 at 01:03):
Not really. There isn't an all-encompassing grouper that can point to every single Observation that gets created against the study and indicates the relative offset. An Observation just gets posted and one of the data elements in it is "what study day did this occur on?"
Grahame Grieve (Feb 16 2018 at 01:26):
so the's a study specific thing, no?
Lloyd McKenzie (Feb 16 2018 at 02:37):
Yes, but the study can't point to every observation (in every clinic in every organization) that's related to the study. It's not the same as a plan definition or a complex order where everything gets created at once and is pre-organized at creation time.
Bryn Rhodes (Feb 16 2018 at 18:15):
Okay, so a "relatedEvent" extension with the same structure as "relatedAction" but that could be applied to a resource, right?
