Summary
This summary is machine-generated.

Objective performance indicators (OPIs) from robotic lobectomy (RL) data revealed significant differences in technical skill between surgical trainees and attending surgeons. This data-driven approach can establish objective competency benchmarks for surgical training.

Area of Science:

  • Robotic Surgery
  • Surgical Education
  • Surgical Skill Assessment

Background:

  • Current surgical performance assessments are subjective and biased.
  • Objective performance indicators (OPIs) derived from robotic surgical systems can objectively differentiate technical skill.
  • Robotic lobectomy (RL) offers a platform for evaluating these OPIs.

Purpose of the Study:

  • To compare OPIs between surgical trainees and attending surgeons during robotic lobectomy.
  • To assess the ability of OPIs to differentiate technical skill levels in robotic surgery.
  • To evaluate the utility of a novel data recorder for capturing surgical performance metrics.

Main Methods:

  • Fifty cardiothoracic surgery residents and 7 attending surgeons performed RL on a perfused ex vivo model.
  • A novel recorder captured simultaneous video and system/instrument data.
  • OPIs were analyzed for both hands across 6 discrete tasks, including exposure and stapling.

Main Results:

  • Significant differences in OPIs were observed between attendings and trainees across all tasks.
  • Trainees showed significant differences in 52% of left-hand and 70% of right-hand OPIs during exposure tasks.
  • Trainees demonstrated significant differences in 47% of stapling-hand and 25% of non-stapling hand OPIs during stapling tasks.

Conclusions:

  • A novel data and video recorder effectively generated OPIs, revealing significant differences in operative gestures between trainees and attendings during RL.
  • This objective assessment method shows potential for establishing competency benchmarks in robotic surgery.
  • OPIs can be utilized for tracking surgical skill progression in trainees.
