A Medication Administration Record (MAR) is a legal healthcare document, maintained within an Electronic Health Record, that details all medications prescribed to a patient. It lists drug names, dosages, administration routes, scheduled delivery times, and records the exact time and nurse signature for every dose administered.
Key components of an electronic MAR
An electronic MAR serves as the primary communication tool between prescribers, pharmacists, and bedside nurses regarding drug therapy:
- Prescription Details Displays the official medication order, including active drugs, dosages, routes (e.g., IV, oral), and frequency.
- Scheduling Grid Highlights upcoming scheduled doses, PRN (as-needed) medications, and overdue administrations.
- Administration History Logs timestamps, dosage calculations, nurse signatures, and rationales for held or refused doses.
- Safety Alerts Flags potential allergy conflicts, drug-drug interactions, and required lab verifications prior to administration.
The role of the MAR in patient safety
Proper use of the MAR enforces the core rights of medication administration: right patient, right drug, right dose, right route, and right time. Learning to navigate an electronic MAR accurately is essential for reducing clinical medication errors.
