Operative product quality and time to completion effectively measure surgical technical skill in residents. These metrics offer efficient alternatives for assessing competence in bench model examinations.

Area of Science:

  • Surgical Education
  • Medical Simulation
  • Assessment of Technical Skills

Background:

  • Evaluating technical skill in surgery is crucial for resident training.
  • Traditional assessment methods can be time-consuming and subjective.
  • Objective measures are needed to complement existing evaluation techniques.

Purpose of the Study:

  • To determine if operative product and time to completion can serve as valid measures of technical skill in general surgery residents.
  • To compare the effectiveness of these metrics against traditional scoring methods.

Main Methods:

  • A 6-station bench model examination was conducted with 20 general surgery residents (11 PGY4, 9 PGY5).
  • Time to completion for each station was recorded.
  • Faculty surgeons evaluated the quality of the final operative product using a 5-point scale.

Main Results:

  • Higher-level residents (PGY5) achieved significantly better product quality scores and shorter completion times than junior residents (PGY4).
  • Interrater reliability for product quality was 0.59, and for time to completion, it was 0.72.
  • There was substantial agreement between faculty ratings and the objective measures of product quality (63%) and time (78%).

Conclusions:

  • Operative end product analysis and time to completion are efficient and reliable measures of technical competence.
  • These objective metrics provide valuable alternatives to on-line examiner scoring in surgical bench model examinations.
  • The findings support the use of these measures for assessing surgical skill development in residency programs.
