subject
A reference to the patient.
Within a FHIR Messaging or FHIR Document implementation, include a Profile UKCore-Patient resource within the Bundle with at least the minimum dataset populated as defined within the UK Core standard. The MedicationStatement.subject.reference
points to the resource in the Bundle.
Within a RESTful implementation a MedicationStatement.subject.reference
and/or MedicationStatement.subject.identifier
SHALL be provided that allows the consumer system to query another API if they need to access the complete Profile UKCore-Patient resource.
For implementations within England and Wales, the MedicationStatement.subject.identifier
could be the patient's NHS Number, allowing a consumer system to use the NHS England Personal Demographics Service FHIR API to return a Patient resource.
For implementations within Scotland, the MedicationStatement.subject.identifier
could be the patient's CHI Number.
