(I split this question off from a previous thread since it did not really match the overall topic there, hope that is OK - Lloyd McKenzie Melva Peters FYI)

A possible status for MedicationStatements (MedicationUsage in R5) is "intended", i.e. such resources can make the statement that a patient will be taking a given medication in the future. It seems that such a statement follows automatically from a MedicationRequest/-Dispense resources (supposing they have a appropriate status values) - an fresh prescription implies that the patient should be taking the prescribed medication in the future etc.. That, in turn, would mean that one could automatically generate MedicationStatements from (certain) MedicationRequest/-Dispense instances.

Specifically, suppose I have a MedicationRequest with the following properties (something similar would work with MedicationDispense):

• status = "active" (or "completed")
• intent = "order"
• requester = Doctor X
• authoredOn = date D
• medication = medication M

Then it seems one can automatically derive a MediationStatement/-Usage with the following properties:

• status = "intended"
• basedOn = [medication request above]
• dateAsserted = date D
• informationSource = Doctor X
• medication = medication M

Would this be considered legitimate or would such a conversion violate the semantics of the involved resources? Rob Hausam Christof Gessner I am curious if there has been explicit discussion of this in the community of IPS implementers, given that the IPS IG explicitly acknowledges that the IPS medication summary can be build from prescription or dispense lists.

The notion of "MedicationUsage deriving from a prescription" seems your own business logic. I actually want to do the same, because I need to capture a "snapshot" of medication usage, whether this is from a patient statement or something else.

1. is it a valid mapping? I think so.
2. is this mapping a standard approach? I don't think so. You can also derive snapshots from other artifacts, like Dispenses.
