Setting expert performance standards for virtual reality laparoscopic training can improve surgical skill acquisition. The challenging "EXP-1" expert level, unlike the lenient "EXP-C" level, appears most effective for proficiency.

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Virtual Reality Training

Background:

  • Virtual reality (VR) simulation is effective for laparoscopic training.
  • Skill acquisition rates in VR laparoscopic training vary significantly.
  • Establishing expert performance benchmarks may enhance training efficiency.

Purpose of the Study:

  • To define expert performance levels for virtual reality-based laparoscopic skills training.
  • To evaluate the impact of different expert benchmark levels on resident skill acquisition.

Main Methods:

  • Four expert laparoscopic surgeons performed 12 tasks multiple times to establish expert performance benchmarks (EXP-1 and EXP-C).
  • Thirty-seven surgery residents and two research residents completed the same tasks to assess baseline performance.

  • Participant scores were compared against established expert levels.

    • Main Results:

    • Only 19% of residents reached the composite expert level (EXP-C), while just 3% reached the highest expert level (EXP-1).
    • The EXP-1 level was achieved by both research residents, indicating its challenging nature.
    • The EXP-C level was found to be too lenient for assessing proficiency.

    Conclusions:

    • The EXP-1 expert performance standard is a more rigorous benchmark for virtual reality laparoscopic training.
    • Implementing challenging, expert-defined performance standards like EXP-1 is crucial for ensuring adequate skill acquisition in surgical residents.
    • Further development and integration of such standards into surgical curricula are recommended.
