How does barcode scanning contribute to medication safety, and what steps when scanning is unavailable?

• A. Scanning verifies patient and drug before administration; if down, follow a documented downtime protocol with manual verification and supervisor checks.
• B. Scanning ensures dosing accuracy.
• C. Scanning replaces patient verification.
• D. Scanning only checks inventory.

Answer: (A)

Barcode scanning acts as a safety check that links the patient’s identity with the medication being prepared or given, helping ensure the right patient receives the right drug, at the right dose, by the right route and at the right time. It also helps catch mismatches and can flag issues such as incorrect labeling or expired medications, creating an electronic record of the verification that supports accountability and traceability.

When scanning is unavailable, follow a documented downtime protocol. This means switching to manual verification steps defined by policy, including confirming the patient’s identity with two identifiers and verifying the medication against the order, checking the drug name, strength, expiration date, and route, and ensuring the timing is correct. For high‑alert or high‑risk medications, a second qualified clinician should perform a double-check before administration. Document the downtime actions, who performed them, and any manual verifications, and ensure the medication administration is recorded appropriately. Once systems are back online, reconcile manual records with the electronic system and resume scanning.
