Summary
Visual cues significantly improve nurses' prospective memory (PM) for future tasks in critical care settings. Enhancing cue visibility can support nurses in managing essential patient care duties.
Area of Science:
- Healthcare simulation
- Cognitive psychology
- Nursing practice
Background:
- Prospective memory (PM) is crucial for patient safety in healthcare, involving remembering future tasks.
- Limited research exists on PM in clinical settings, despite potential dangers of forgotten tasks.
- Visual cues are known to aid prospective memory performance.
Purpose of the Study:
- To investigate the impact of visual cues on nurses' prospective memory for future tasks.
- To explore how nurses manage prospective memory demands in a simulated critical care environment.
Main Methods:
- Utilized an intensive care unit simulator for a 40-minute morning shift scenario.
- Included eight prospective memory tasks with manipulated presence or absence of visual cues.
- Assessed the performance of 24 participating nurses.
Main Results:
- Nurses demonstrated improved recall with visual cues present (64%) compared to no cues (50%).
- The presence of visual cues significantly enhanced task execution (p = 0.03 one-tailed, η(p)(2) = 0.15).
- Nurses employed deliberate reminders to manage prospective memory demands.
Conclusions:
- Visual cues enhance nurses' prospective memory performance in simulated critical care settings.
- Increasing the visibility of task-related cues may support nurses in managing prospective memory.
- Findings suggest practical strategies for improving patient safety through enhanced memory support systems.
