Summary
Expert clinicians in paediatric emergencies focus on critical areas like the chest and airway. This gaze behavior, observed using eye-tracking, mirrors findings in other high-stakes fields like aviation and surgery.
Area of Science:
- Medical Education
- Clinical Skills Assessment
- Human Factors in Medicine
Background:
- Expert-novice differences in gaze behavior are established in aviation and surgery.
- Understanding gaze patterns in medical emergencies can reveal expertise-related insights.
Purpose of the Study:
- To describe and compare the gaze behavior of clinicians with diverse training backgrounds during a simulated pediatric emergency.
- To identify differences in visual attention strategies among clinicians during critical care scenarios.
Main Methods:
- Utilized eye-tracking glasses (SMI) to record gaze behavior in clinicians from four different clinical areas during a simulated pediatric emergency.
- Measured fixation count, dwell time on predefined areas of interest, and time to critical interventions.
Main Results:
- Pediatric Intensive Care Unit (PICU) consultants demonstrated superior performance, focusing longer on the chest and airway.
- Pediatric consultants and trainees spent more time viewing the defibrillator and algorithm compared to PICU and pediatric emergency medicine consultants.
Conclusions:
- This study is the first to document gaze behavior differences between experts and novices in a resuscitation setting.
- Observed gaze patterns align with those previously reported in aviation and surgery, suggesting transferable expertise principles.
- Eye-tracking technology shows potential as an educational tool for improving clinical skills and decision-making in emergency medicine.
