Resource Profile: IE MPD MedicationStatement

What a patient is taking, has taken or will take, as reported by the patient, a carer or a clinician (a medication use statement), derived from the HL7 Europe Base MedicationStatement (medicationStatement-eu-core). Traced to the HIQA draft Patient Summary Section 6.3 (Medication). Aligned with the Xt-EHR EHDSMedicationUse logical model v1.0.0; the R5 equivalent is MedicationUsage.
