NB! This is a new e-mail on the same subject since I didn’t see any mail on the mailing list. Just to check if it is working
We are currently developing a module for Careplan based on openEHR Archetypes. We are using INSTRUCTION/ACTIVITY/ACTION archetypes to model the clinical process.
One issue we are facing is the need to define which transitions that are allowed for a given Careflow Step.
To explain I will use openEHR-EHR-ACTION.medication.v1 as example. This ACTION archetype have Review medication as an possible ISM_TRANSITION. This is an transition that ends in ACTIVE state.
What we want to express is that this careflow step is only allowed for an active step (openehr::543). This means that is it not allowed to do this careflow step as a start transition (openehr::540).
A proposed ADL definition for this is given below:
ISM_TRANSITION[at0005] matches { – Review medication
current_state matches {
DV_CODED_TEXT matches {
defining_code matches {[openehr::245]}
}
}
transition matches{
DV_CODED_TEXT matches {
defining_code matches {[openehr::543] } – only allow transition 543 (active)
}
}
careflow_step matches {
DV_CODED_TEXT matches {
defining_code matches {[local::at0005]} – Review medication
}
}
}
To expand this example we want to allow only two transitions, i.e. “active step” (openehr::543) and “resume” (openehr::546).
A proposed ADL definition for this is given below:
ISM_TRANSITION[at0005] matches { – Review medication
current_state matches {
DV_CODED_TEXT matches {
defining_code matches {[openehr::245]}
}
}
transition matches{
DV_CODED_TEXT matches {
defining_code matches {[openehr::543],[openehr::546] }
}
}
careflow_step matches {
DV_CODED_TEXT matches {
defining_code matches {[local::at0005]} – Review medication
}
}
}
And then the questions:
-
Is the first example allowed?
(defining the allowed transition) -
Is the second example allowed?
(defining two allowed transitions)
