eMAR (Medication Administration)

February 2026 · 5 min

Overview

The Electronic Medication Administration Record (eMAR) tracks every medication dose given to an inpatient -- from the doctor's order through pharmacy verification to bedside administration by the nurse. It closes the medication safety loop with barcode verification and real-time documentation.

Medication Administration Workflow

The eMAR workflow follows five rights of medication administration:

1. Right Patient -- Barcode scan of patient wristband
2. Right Drug -- Barcode scan of medication package
3. Right Dose -- System confirms dose matches the active order
4. Right Route -- Route displayed and confirmed (oral, IV, IM, SC, etc.)
5. Right Time -- Time window validation (early, on-time, late)

The nurse scans the patient wristband, scans the medication, the system validates all five rights, and the nurse confirms administration. Any mismatch triggers an alert.

MAR Grid View

The MAR grid shows a patient's complete medication schedule:

• Rows = medications, Columns = time slots
• Color-coded cells: Green (given), Yellow (due), Red (overdue), Gray (held/discontinued)
• Click a cell to record administration with notes
• PRN (as-needed) medications shown in a separate section
• Running IV fluids with rate and remaining volume display
• Cumulative dose tracking for dose-limited medications (e.g., acetaminophen daily max)

Alerts & Safety

The eMAR generates real-time safety alerts:

• Overdue medication alerts (configurable threshold, e.g., 30 min past due)
• Missed dose notifications to the charge nurse
• High-alert medication warnings (e.g., insulin, heparin, chemotherapy)
• Allergic reaction flag if medication matches patient allergy
• Maximum dose exceeded warning
• Duplicate administration prevention (same drug given twice in the time window)

Reporting

eMAR reports include:

• Medication administration compliance rate (% of doses given on time)
• Missed dose report by ward, nurse, or medication
• Near-miss event log (wrong drug scanned, wrong patient scanned)
• High-alert medication administration audit
• Controlled substance administration log with witness documentation
• Nurse workload analysis (administrations per shift)
