Resource Profile: IE MPD MedicationRequest (ePrescription)

An Irish electronic prescription (eP): one prescribed medication (HIQA EP 3.5 prescription item), derived from the HL7 Europe MPD MedicationRequest. One or more eP issued together as part of the same request form an Electronic Prescription Group (IEMpdElectronicPrescriptionGroup): they share the prescription group identifier in groupIdentifier and are exchanged with the patient, prescriber, facility, allergy statement, eDispensations and provenance.
