This is correct: semantic notions are expressed as archetypes. But what is the EHR? Answer: the record that documents what the healthcare provider received as data, his thoughts, his professional opinion, the plan, the orders, and what he wants exchanges with others. The EHR is a document that documents. Then the EHR is the record of what happened. In that context it records that an order was given to dispense medication. But this is not the same as the medication order itself. When this information is sent to the pharmacist he will interpret it as an instruction for him to dispense. When the same piece of information is sent to the patient it means that this is the record of what he was advised to do, or is the meaning that this is an prescription he must bring to the pharmacist, In other words. An EHR with a record of something (e.g. an instruction) needs something extra that indicates what the purpose is. A record of an order is not the same as the order itself. My question was: how will OpenEHR (EHRcom) indicate what the purpose of the order is? Will we indicate this inside the EHRextract? Will we indicate this in the envelope? Will we leave this completely to the HL7 machinery of messages.
