This study validates nine robotic surgery training exercises. Experts showed superior performance, with similar workload and low frustration for both experts and novices, confirming their suitability for proficiency-based robotic training.

Area of Science:

  • Robotic Surgery
  • Surgical Education
  • Medical Simulation

Background:

  • Nine inanimate training exercises were developed for a comprehensive, proficiency-based robotic surgery curriculum.
  • These exercises target 23 unique skills identified through task deconstruction of robotic procedures.

Purpose of the Study:

  • To evaluate the construct validity of the nine robotic training exercises.
  • To assess workload levels experienced by trainees and experts during these exercises.
  • To establish expert performance benchmarks for the training modules.

Main Methods:

  • Eight expert robotic surgeons and four novice trainees performed nine standardized exercises.
  • Performance was measured using modified Fundamentals of Laparoscopic Surgery (FLS) metrics for time and accuracy.

  • Participants completed the NASA-TLX Workload Scale after each exercise to assess perceived effort and difficulty.

    • Main Results:

    • Experts demonstrated significantly higher performance scores across all nine tasks and the composite score compared to novices (P < 0.001).
    • No significant differences in overall workload were detected between expert and novice groups.
    • Frustration levels were reported as low for both participant groups, indicating good task acceptance.

    Conclusions:

    • The nine structured exercises exhibit construct validity, as evidenced by objective performance metrics.
    • The exercises are suitable for proficiency-based robotic training due to demonstrated construct validity and acceptable workload.
    • These findings support the integration of these exercises into robotic surgery curricula to enhance surgical skill acquisition.
