Which option best describes an example of cognitive ergonomics in healthcare IT?

• A. Designing a decision-support interface to support clinician reasoning
• B. Scheduling shifts to prevent fatigue
• C. Adjusting chair height to reduce discomfort
• D. Providing better lighting

Answer: (A)

Cognitive ergonomics in healthcare IT focuses on how information and interfaces shape clinicians’ thinking, memory, and decision making. The best example is designing a decision-support interface that guides clinician reasoning by presenting relevant data, highlighting important trends, and providing evidence-based recommendations at the point of care. This directly supports the cognitive work of diagnosing and choosing treatments, reducing mental workload and the potential for misinterpretation.

The other options target physical or organizational aspects rather than the mental processes involved in using an information system: scheduling shifts to prevent fatigue relates to workload management and fatigue, not how information is processed; adjusting chair height and providing better lighting affect physical comfort and environmental conditions, not cognitive information processing.
