What is one documented benefit of using barcode scanning in medication administration?

• A. Reduces incorrect patient/med pairing
• B. Increases time to administer
• C. Eliminates the need for MAR
• D. Replaces patient identification

Answer: (A)

Barcode scanning enhances patient safety by electronically verifying that the right drug is given to the right patient. The system reads the patient’s identification from their ID band and the medication’s barcode, then cross-checks this against the MAR entry for that patient. If everything matches, administration proceeds; if not, the system alerts and blocks the order. This direct check reduces the chance of incorrect patient/med pairing, a common source of medication errors.

The MAR remains the formal record and is still used, so barcode scanning does not eliminate it. It also does not replace patient identification; it reinforces proper identification rather than removing it. While the process adds a step, the significant safety benefit is preventing wrong-patient and wrong-drug administration.
