Area of Science:

  • Medical Simulation
  • Surgical Skill Assessment
  • Medical Education Technology

Background:

  • Traditional metrics for simulator performance may not adequately assess complex procedures like laparoscopic suturing.
  • Objective assessment of surgical trainees is crucial for skill development and patient safety.

Purpose of the Study:

  • To develop and validate a novel metric for objectively assessing laparoscopic suturing skills in a simulated environment.
  • To evaluate the correlation of the new metric with traditional performance measures and expert subjective assessments.

Main Methods:

  • A software program was created to calculate the percentage of time spent operating within predefined
  • zones
  • on the ProMIS III simulator.
  • Twenty-five participants (medical students, surgical residents, laparoscopic experts) performed a laparoscopic suturing task.
  • New
  • in-zone
  • and
  • out-zone
  • scores were generated alongside traditional metrics (time, path length, smoothness) and compared with blinded observer ratings (OSATS, FLS).

Main Results:

  • Significant differences in
  • in-zone
  • and
  • out-zone
  • scores were observed across all experience groups (p < 0.05).
  • The new zone metric scores showed significant correlation with blinded observer assessments (OSATS, FLS; p = 0.0001).
  • The zone metric scores also correlated significantly with traditional metrics like path length, time, and smoothness (p < 0.05).

Conclusions:

  • The novel
  • in-zone
  • /
  • out-zone
  • metric is a valid and objective tool for assessing laparoscopic suturing performance in simulators.
  • This metric can be integrated into competency-based curricula to monitor resident skill progression.
