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
