Summary

Medical trainees improved technical skills and self-assessment accuracy with simulation practice. Repeated practice enhanced their ability to estimate errors, supporting self-directed skills training in residency programs.

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Skill Acquisition

Background:

  • Simulation-based training offers limited feedback, necessitating reliance on self-assessment.
  • Medical trainees exhibit deficits in accurately self-assessing their technical skills.
  • Existing simulation technologies require further investigation for their efficacy in self-assessment training.

Purpose of the Study:

  • To evaluate the capability of medical trainees to self-assess technical skills during simulation-based training.
  • To determine if repeated practice with a simulation-trainer improves self-assessment accuracy.
  • To compare trainee self-assessment of performance with objective simulator data.

Main Methods:

  • Twenty-one medical students completed 10 repetitions of a simulated surgical task.

  • After each task repetition, students estimated their completion time and number of errors.
  • Self-estimated performance data were compared against objective data recorded by the simulator.

    • Main Results:

    • Task performance, measured by time and errors, significantly improved with task repetition (P < 0.0001).
    • Trainees' self-assessment curves mirrored their actual performance improvement curves (P < 0.0001).
    • While self-assessed time accuracy did not improve (P = 0.26), error estimation accuracy significantly increased with practice (P = 0.01).

    Conclusions:

    • Simulation-based practice facilitates skill acquisition and improves self-assessment accuracy in novice medical trainees.
    • Enhanced accuracy in error estimation suggests that practice refines self-monitoring capabilities.
    • These findings support the integration of self-directed learning and simulation into residency training curricula.
