Motion Analysis-Based Skills Training and Assessment in Pediatric Laparoscopy: Construct, Concurrent, and Content...

Area of Science:

• Surgical Simulation
• Medical Education Technology
• Pediatric Surgery

Background:

• Pediatric laparoscopy requires specialized training.
• Objective assessment tools are crucial for surgical skill development.
• The eoSim simulator offers a potential platform for laparoscopic training.

Purpose of the Study:

• To validate the eoSim simulator for pediatric laparoscopy training.
• To assess the simulator's ability to measure surgical skills.
• To compare eoSim performance with existing assessment methods.

Main Methods:

• 28 participants (experts, intermediates, novices) were stratified by experience.
• Three tasks were performed on eoSim and Pediatric Laparoscopic Surgery (PLS) simulators.
• Skill assessment used motion analysis for eoSim and a validated scoring system for PLS.

Main Results:

• eoSim demonstrated favorable content validity.
• Motion analysis parameters (path length, speed, acceleration, smoothness) showed construct validity.
• Significant differences in task completion times and scores were observed across experience levels for both simulators.

Conclusions:

• The adapted eoSim simulator is a valid tool for pediatric laparoscopy training.
• Future work should focus on proficiency-based training curricula using derived metrics.
• eoSim shows promise for enhancing surgical education in pediatric laparoscopy.
