Sam,

I do not know the openehr rm well so I spend some time  
this week to read the documentation.  
I would like to get involved in the detailed debate  
about order entry. From my point of view there are two  
different requirements/types for an order entry  
instruction in general:  
1. This is the ususal order entry process which is  
concerned with process execution (laboratory order  
entry). You send an order and get a result.  
2. This is the scheduling process of order entry. This  
process is more patient centered. You send an order  
and you get an appointment (e.g. radiololgy  
department).  
Both concepts are quite general, so I am not sure if  
there have to exist a separate instruction for each of  
them.  
What I am concerned with is the clinical information  
which should go along/ or should be available with an  
order of type 2. In the past months I tried to model  
this information for specific orders (CT, Left heart  
catheterization) with the aim to give the clincian  
performing the investigation the information already  
gathered by the ordering physician. (The main purpose  
of this modeling was to give the clinican executing  
the order the possibility to verify the indication of  
the requested investigation and to make the report  
more comprehensible and contextual to the order... )  
I am not sure how such a model could be integrated in  
the openEHR model and at what level this could happen.

I would be glad to hear from you why I keep on reading  
the documentation..  
Regards  
Dirk
