statusReason

A coded reason for why an administration was not performed.

SHOULD only be populated when the MedicationAdministration.status is either stopped, not-done or on-hold.

Example scenarios for the use of status and statusReason.

Some medication was taken, but not all that was intended, for whatever reason, e.g. an infusion that was started, and finished prematurely.

• status = stopped
  
• status reason = 416093006 | Allergic reaction to drug
  
• dosage = Should reflect how much was actually administered, e.g. 150ml (instead of 200ml requested)

Note: For this example it would be expected that the originating MedicationRequest would be updated with a status of stopped which should prevent the system from scheduling an administration or delete any that have been scheduled. Where administration records are retained, use the status of stopped.

Patient refused to take the medication.

• status = not-done
  
• statusReason = 182895007 | Drug declined by patient (finding) - or a child concept of the above

Where required use MedicationAdministration.note to capture additional notes for why the patient refused the medication.

Patient not available, e.g. on home leave for a couple of days, moved ward, location unknown, etc. and not recorded as on-hold.

• status = not-done
  
• statusReason = 398090008 | Patient unavailable (finding)
  
  

Medication was taken but patient then vomited all/some of the medication.

• status = on-hold or stopped
  
• statusReason = 419219000 | Drug-induced nausea and vomiting

Use MedicationAdministration.note for additional notes for what happened, provided the administration record can be amended after the vomiting episode.

An infusion for the patient is paused for a period based on blood test results. Or, a nutrition feed is paused for clinical reasons, to restart again later.

• status = on-hold
  
• statusReason = Optional. Any valid SNOMED term.
  
• dosage = The dosage would either be recorded with a zero rateRatio or rateQuantity or may be fully omitted. Both must be interpreted as a zero medication administration.
