A Medication Administration Record (MAR) is a formal, legal document used in healthcare settings to track every medication dose given to a patient. It serves as a continuous, chronological account of a patient’s medication regimen, ensuring providers have a clear history of what has been administered. Accurate documentation provided by the MAR prevents potential medication errors and ensures safe patient care. This record is a permanent part of the patient’s medical chart, holding clinicians accountable and supporting continuity of care across shifts and different providers.
Defining the Medication Administration Record
The primary function of the Medication Administration Record is to act as the official proof that a prescribed medication order was carried out as intended. It links the prescribing doctor’s orders with the hands-on administration by nurses or other authorized staff. This documentation process is structured around the “Five Rights” of medication administration: Right Patient, Right Drug, Right Dose, Right Route, and Right Time. By diligently recording each administration, the MAR allows healthcare teams to monitor adherence and track patient response. For example, the record of an as-needed (PRN) medication includes the reason for administration and the patient’s resulting outcome, which informs future care decisions. Because it is a legal document, the MAR is subject to audits and must be maintained with precise detail to comply with health regulations.
Critical Information Recorded on the MAR
A complete Medication Administration Record must contain specific, detailed information to ensure the correct medication process is followed and documented. This begins with clear patient identification, including the patient’s full name, date of birth, and a unique medical record number. A detailed list of all known patient allergies must also be prominently displayed. The MAR documents the prescription itself, listing the generic or brand name of the medication, its strength, and the exact dosage. It specifies the intended route of administration (e.g., oral, intravenous, or topical) and the scheduled frequency or administration time. For every dose administered, the clinician must document the exact date and time, along with their initials or signature, creating a clear audit trail. If a medication is not administered, the MAR must record the omission, noting the specific reason, such as a patient refusal.
How Electronic MAR Systems Enhance Safety
The transition from traditional paper charts to Electronic Medication Administration Records (eMARs) has significantly improved safety by mitigating the risks inherent in manual systems. Electronic systems eliminate common issues like illegible handwriting, which is a frequent source of transcription errors. The eMAR provides a real-time, instantly accessible record that is automatically synchronized with the patient’s Electronic Health Record (EHR) and the pharmacy’s dispensing system.
A major safety enhancement is the integration of Barcode Medication Administration (BCMA) technology. This process requires the clinician to use a handheld scanner to verify the barcode on the patient’s wristband and the barcode on the medication package immediately before administration. This dual-scanning procedure automatically checks all “Five Rights” by confirming the patient, drug, dose, route, and time against the electronic order, creating a closed-loop system. Studies have shown that the implementation of eMAR and BCMA can lead to significant reductions in overall medication error rates.
Electronic systems also incorporate clinical decision support features. The eMAR can generate immediate alerts for potential drug-allergy contraindications or harmful drug-drug interactions based on the patient’s current profile. These automated safeguards intervene at the point of care, providing a final electronic verification layer that supports the clinician in making safe administration decisions. This technological approach improves efficiency by streamlining documentation while simultaneously enforcing safety protocols.
