Computer-based video training (CBVT) effectively teaches surgical skills to novices in a self-directed setting. Trainees improved performance regardless of additional practice, supporting digital learning integration.

Area of Science:

  • Surgical Education
  • Medical Simulation
  • Digital Learning

Background:

  • Computer-based video training (CBVT) offers flexible surgical skill acquisition.
  • Self-directed practice with CBVT may be limited by poor trainee self-assessment.
  • This study investigates CBVT efficacy in a self-directed novice environment.

Purpose of the Study:

  • To evaluate the effectiveness of CBVT for novice surgical trainees in a self-directed learning context.
  • To determine if additional practice beyond self-assessed proficiency impacts skill acquisition.
  • To assess the impact of self-assessment accuracy on learning outcomes.

Main Methods:

  • Thirty novice trainees utilized CBVT to learn the 1-handed square knot, self-assessing every 3 minutes.

  • Participants were randomized to either stop practice upon reaching self-assessed proficiency or continue practicing.
  • Performance was measured using computer and expert evaluations during practice and on retention tests.

    • Main Results:

    • Both groups demonstrated significant performance improvements across all skill assessments (P < .05).
    • No significant differences in performance were observed between the groups that ceased practice and those that continued (P > .05).
    • Skill retention was maintained at 1 week for all participants.

    Conclusions:

    • Computer-based video training is an effective method for teaching the 1-handed square knot to novice surgeons in a self-directed learning environment.
    • The findings support the integration of self-directed, digital media-based learning modules into surgical training curricula.
    • Self-assessment within CBVT appears sufficient for novice skill acquisition without mandatory additional practice.
