Developing expert performance benchmarks for surgical simulation training is feasible. These benchmarks are challenging for novices but attainable for experienced trainees, optimizing surgical skills curriculum.

Area of Science:

  • Surgical Education
  • Medical Simulation
  • Laparoscopic Skills Training

Background:

  • Basic video-trainer curricula require defined training endpoints.
  • Establishing objective expert performance levels is crucial for skill acquisition.

Purpose of the Study:

  • To develop and validate expert performance benchmarks for a basic laparoscopic skills curriculum.
  • To assess the suitability of these benchmarks as training endpoints.

Main Methods:

  • Fifty subjects (medical students, surgical residents) performed 5 validated video-trainer tasks.
  • Expert surgeons (n=4) established competency levels based on trimmed mean scores.
  • Baseline performance was compared against established expert levels.

Main Results:

  • Only 6% of subjects reached the competency level by the third trial.
  • Chief residents (73%) were more likely to achieve the expert level than medical students.
  • The expert benchmark proved challenging for novices but achievable for experienced trainees.

Conclusions:

  • The developed expert levels are suitable training endpoints for basic laparoscopic skills.
  • Implementing these performance criteria can optimize training efficiency and trainee benefit.
  • This approach helps minimize unnecessary training for surgical residents.
