MediRecords used the patient's IHI Number (Individual Healthcare Identifier) to detect whether or not the patient has registered for My Health Record. The system will automatically populate the patient's IHI number (where available) when OPV is run for the first time.
This is found in the patient profile > Details Tab > Settings.
My Health Record is located within Clinical in the patient record. When you open a patient's clinical record, the system will automatically check whether or not My Health Record is active, and the MHR Icon will appear in either Blue, Orange or Green (depending on your level of access to the record).
