Hi Thomas,
In our implementation of a Trauma EHR, we don't have an explicit state machine
with the status of the action to work with, we only have a record of what was
done.
Trauma is a quick care act, and the physicians only want to check what actions
they do on the patient, and in this case the description of the care act is
enough for our record detaile level.
I understand in something like give medication in an ICU has to follow a state
machine for what was planned, active, suspended, etc, but in trauma a
medication is given without a plan and is a one time thing, so it can't be
suspended or cancelled.
I also want to know the experience of other people modeling their "action" care
entries.
Best regards,Pablo Pazos Gutierrez

Hi,
In the specs I see that ACTION has a mandatory relationship to ISM_TRANSITION.
In my project I
only use the "description" field of ACTION to record information about
the ACTION and I don't have information to fill the ISM_TRANSITION.
My question is: why
the ISM_TRANSITION of the ACTION is mandatory instead of optional?
the idea is that all Actions follow a state machine model (documented
in the EHR IM spec). Even the simplest one will do this, and it is
always useful to know whether the Action puts the relevant Instruction
into a new state. If you know the state, you can query for all
Instructions that are currently Active, Suspended, Completed etc etc.
If you don't know the state, it is probably 'Active'.
If we make this optional, many implementers are likely to ignore the
state, but it is the single most important thing for clinical users -
some people would argue that this is the most important attirbute in
the whole model in fact.
I am certainly interested to hear other views on this.
