How does barcode patient identification contribute to safety?

• A. Increases medication potency
• B. Reduces need for MAR checks
• C. Verifies patient identity against orders, reducing wrong-patient administration
• D. Eliminates pharmacist review

Answer: (C)

Barcode patient identification centers on confirming that the person receiving the medication is the correct patient for the ordered drug. By scanning the patient’s wristband barcode and the medication’s barcode, the system verifies that the medication order on the MAR belongs to that patient and matches the intended drug, dose, route, and time. If anything doesn’t align, an alert blocks administration, preventing a wrong-patient error. This directly supports the right-patient principle of safe medication administration and provides an electronic trail of what was given, to whom, and when.

This safety step does not change the drug’s potency; potency is a pharmacologic property, not a function of barcode scanning. It does not eliminate the need for MAR checks—barcode verification is an additional safeguard that complements, rather than replaces, MAR review. It also does not eliminate pharmacist review; pharmacists still assess orders for accuracy, allergies, interactions, and appropriateness. The value of barcoding lies in reducing wrong-patient administration by ensuring linkage between the patient, the order, and the medication at the point of care.
