Hi, I'm currently working in a group that has been evaluating archetypes and they found out that there in archetypes may be needed to add external nodes from other archetypes instead of only adding complete archetypes as slots. Does the current ADL specification allow that external parts from other archetypes can be included? I think the openEHR templates allow to cut off parts in a slot, but I'm not sure if they can exclude everything except a single item.
The group also found out that there is a need to deduct certain answers depending on previously answered questions. For example if we previously answered that the blood pressure was above 160, then another question about hypertension should be answered automatically. Is this possible to do in archetypes? Another issue is about computation. For example we could want a quantifiable magnitude to be the result of two previously entered values. Is this possible to do in archetypes? Perhaps in the declaration section or the invariant section? I've seen that these sections should contain some kind of first-order predicate logic, but I'm not sure of the scope and limitations/possibilities of these ADL sections. Also, the declaration section is actually not even described in the ADL 1.4 document, it is only shown in an example overview figure. Another feature is value reporting, which should work when we use several archetypes in an openEHR template. For example if some question was answered in one archetype, then another archetype that has the same question should get the value reported from the previous archetype. Is this possible? I guess this has to do with external references as I mentioned in my first question. We would also like to ask if there is a way of specifying validity for questions depending on previously answered questions. E.g. if a certain answer was given from a multiple alternative question (coded_text), then and only then, some other group of questions will be valid. Is this possible to do in archetypes? Perhaps it's possible with invariants? Finally is there a way of specifying the relevance of answers in archetypes. Say for example that if some laboratory results are too old, could an archetype contain some restrictions that make it illegal to answer certain questions because the material that the answers are based upon is too old? I'm not sure if this is related to DSS or something else. Regards, Mattias, via the Link?ping Team. -------------- next part -------------- An HTML attachment was scrubbed...
