3. US-Core
The US Core implementation guide is a set of profiles every US-Realm based EHR FHIR server must support.
The IG provides the data elements, extensions, and terminology to implement the ONC 2015 Edition Common Clinical Data Set (CCDS) and Argonaut requirements. It evolved from the broader Data Access Framework (DAF) initiative. Future US FHIR projects focused on patient and provider access are encouraged to build on US core.

7. Our Big Question
How does a client access the patient medication list?

8. MedicationStatement

9. Queries nailed down Get ‘All’ Meds Get ‘Active’ Meds

Get ‘Active’ Meds
/MedicationStatement?status=active&subject=[id]
Get Active Orders

10. Patient Medication List Query
If I query for MedicationStatement, I will get all patient medications.
If I query for MedicationStatement and MedicationRequest I will get all patient medications, and medication requests which are a subset of the patient medications. This list will include duplicate medications. Clients can dedepulicate by…link (DSTU2-supporting information) and STU3 …‘basedOn’or derived from’)
MedicationAdministration – will have link to MedicationRequest which is duplicated by a MedicationStatement
and MedicationDispense…future
