Yes! this is really clear and has been a great help.
Thanks a lot.
Just to give info that may help other in the future: in our case, the
instruction is a recommendation to do some exercise, and we need to know if the
activity (the exercise) is completed. We consider a completed activity to be
one exercise instance, e.g. one walk in the park. But the recommendation is
something like "walk 30 min/day for 2 weeks", so I think a good approach is to
create one ACTIVITY for each day, and let the patient change the state of each
day's ACTIVITY (scheduled, started, completed).
In this case, if the day passes and the activity was never "active", we'll mark
it as "expired".
Of course, any comments about this scenario are very welcome.

Hi Thomas,
I agree with that, but I think we are talking about
different scenarios. I understand we can have various ACTIONs
for "active" states (and reschedule or suspend/resume
transitions).
My question is: if an ACTIVITY is "completed" (or "aborted"
or "expired", i.e. a terminated state)
is it possible or valid
to start another execution cycle for that ACTIVITY
instance? or,
should I create another
ACTIVITY instance with the same info in order to execute
it? i.e. create another ACTION with state "scheduled" or
"active" for the same ACTIVITY that is "completed".
Ah - good question (sorry, didn't read your earlier post properly!)
The current model is designed is that once an ACTIVITY is completed
by an ACTION putting it into a terminal state, then that's it. So
for things like long term asthma medication, contraceptive pill, or
any chronic condition medication, where the intent of the
prescription (or hospital order) is to be more or less indefinite,
with the patient just getting repeats then the ACTIVITY is always
active or suspended, and never terminated. But even if it is
terminated, e.g. the asthma patient gets better (it does happen!),
it just means that if it has to be restarted, it will be a new
order, which reflects what happens in real life.
The key to this is that what is recorded (in terms of
INSTRUCTION+ACTIVITY, and ACTIONs) should reflect real life of
orders/prescriptions, repeats, not just the taking of the drugs
themselves.
hope this is clearer.
