Topic: Modifiers on reverse chaining

Is there a way to use the :not operator with a reverse chain _has query?
For example:
Patient?_has:Condition:patient:code:not=X,Y,Z
Effectively, this would return any patients that do NOT have a condition of X, Y or Z?

I wouldn't know why not? (pun intended - the spec does seem to allow it)
James Agnew (Apr 17 2020 at 12:18):
I don't think the spec disallows that, but I bet it's not widely supported...
Grahame Grieve (Apr 17 2020 at 12:39):
I don't think the spec says anything either way

Sounds like a change request to clarify would be a good idea @Sean McIlvenna :)

Hello, are there any updates regarding the use of modifiers on reverse chaining?
Lloyd McKenzie (Feb 15 2022 at 15:25):
I'm not sure a change request was ever submitted. @Sean McIlvenna?
Sean McIlvenna (Feb 15 2022 at 15:29):
Nope. I never submitted a change request. While it would be nice to have, it's not a priority for me.
Sean McIlvenna (Feb 15 2022 at 15:29):
Furthermore, even if I were to submit a change request, I doubt it would be very commonly implemented, so I wouldn't see the benefit of it for quite some time...
