Which statement best describes error-proofing relative to other safety interventions in medication administration?

• A. It relies on post-event analysis to prevent future errors
• B. It prevents or detects errors by design, reducing reliance on memory
• C. It delays care to verify every step
• D. It ignores system design in favor of individual vigilance

Answer: (B)

Error-proofing in medication safety means building safeguards into the process so errors are prevented or caught at the point of care, reducing the need to rely on memory or individual vigilance. It focuses on designing the system so the correct action is the easy or automatic action, and potential mistakes are flagged or blocked before they reach the patient. Examples include barcode verification before administration, unit-dose packaging, standardized drug libraries with decision support in computerized order entry, and other design features that require the right steps or reveal mismatches immediately. This proactive, design-driven approach is why it’s the best description: it prevents or detects errors by design rather than waiting to react after an error occurs. In contrast, post-event analysis looks backward at what happened after an error to prevent recurrence, which is not about preventing the error in the moment. Delaying care to verify every step mischaracterizes safety measures as cumbersome or time-wasting, whereas effective error-proofing aims to be efficient while reducing mistakes. Ignoring system design in favor of individual vigilance contradicts the whole idea of building safety into the workflow.
