The Electronic Medicine Administration Record (eMAR); barcode scanning of medications at the time of administration.

emar

The EMAR table is used to record administrations of a given medicine to an individual patient.
Records in this table are populated by bedside nursing staff scanning barcodes associated with the medicine and the patient.

Links to

• emar_detail on emar_id
• pharmacy on pharmacy_id
• prescriptions on pharmacy_id
• poe on poe_id

Important considerations

• The eMAR system was implemented during 2011-2013. As a result, eMAR data is not available for all patients.
