Area of Science:

  • Surgical Education
  • Medical Simulation
  • Performance Assessment

Background:

  • Interpreting surgical performance assessment scores requires established standards.
  • Lack of defined benchmarks hinders accurate evaluation of surgical skills.

Purpose of the Study:

  • To establish technical and nontechnical performance standards for laparoscopic cholecystectomy.
  • To assess the accuracy and credibility of these standards.
  • To determine factors predicting trainee acquisition of these surgical skills.

Main Methods:

  • General Surgery residents' laparoscopic cholecystectomies were observed using Objective Structured Assessment of Technical Skill (OSATS) and Objective Structured Assessment of Non-Technical Skills (OSANTS).
  • Trained raters provided global competent/noncompetent decisions.
  • Statistical analyses, including receiver operator characteristic (ROC) curves, were used to determine standards and predictive factors.

Main Results:

  • Defensible technical (OSATS: 21.04/35.00) and nontechnical (OSANTS: 22.49/35.00) performance standards were established.
  • These standards accurately discriminated competent/noncompetent trainees (94% technical, 95% nontechnical).
  • Trainee level and case experience significantly predicted standard acquisition (AUC 0.83–0.96).

Conclusions:

  • This study provides essential, defensible standards for technical and nontechnical surgical performance.
  • These standards are critical for implementing effective summative assessments in surgical training programs.
  • Establishing clear benchmarks enhances the reliability and validity of evaluating surgical competency.
