I was wondering if there’s any way in ATLAS to obtain the reverse effect of the Source Concept attribute. For example, I’d like to have a criterion that selects all patients with occurrences that map to a given concept set but which do not have a given source concept.
If this were a feature, I’d picture it as a toggle between “is” and “is not” here:
Is there a recommended way to achieve this effect currently in ATLAS? Would this be a feature you think would be worth requesting?
