Functional Workflow

1. Prescription Creation: A healthcare provider creates a MedicationRequest during a patient encounter.
2. Review and Approval: The prescription is reviewed and approved as per facility protocols.
3. Dispensing: The pharmacy dispenses the medication as per the prescription details.
4. Administration and Monitoring: The patient administers the medication, and adherence is monitored.
5. Status Updates: The status of the MedicationRequest is updated based on the medication's lifecycle (e.g., completed, stopped).
