What is a key human factors principle in patient safety?

• A. Avoid reliance on memory
• B. Rely on memory to speed up processes
• C. Use complex automation without testing
• D. Maximize multitasking

Answer: (A)

In patient safety, systems are designed to reduce the chances that a human mistake due to memory lapses will cause harm. Relying on memory is risky because recall can falter under stress, fatigue, or interruptions. The best principle is to provide external supports and standardized processes that guide actions and catch omissions. This includes tools like checklists, standardized order sets, defined handoff protocols, and safeguards such as barcode scanning, all aimed at ensuring critical steps are completed even if someone momentarily forgets. Using memory to speed up processes increases error risk because faster isn’t safer if it means skipping essential steps. Complex automation without thorough testing can introduce new failure modes if people don’t understand how it behaves or if it doesn’t align with real clinical workflows. Maximizing multitasking raises cognitive load and makes it easier to miss important steps or lose situational awareness. Keeping the workload structured and supported by design reduces these risks and supports safer care.
