Area of Science:

  • Medical Education
  • Surgical Training
  • Assessment Methodology

Background:

  • Current surgical resident evaluations lack objectivity and reliability.
  • Subjectivity in technical skill assessment can hinder effective training.
  • Need for standardized tools to measure surgical competence.

Purpose of the Study:

  • To assess the reliability and construct validity of the Structured Technical Skills Assessment Form (STSAF).
  • To introduce a novel, structured method for evaluating surgical technical ability.
  • To improve the objectivity of surgical resident assessments.

Main Methods:

  • Utilized a two-part Structured Technical Skills Assessment Form (STSAF).
  • Part I: Assessed ~120 procedural components during surgery.

  • Part II: Employed a 10-point global rating post-surgery.
  • Evaluated 41 operations with multiple observers in 26.

    • Main Results:

    • High inter-rater reliability for both STSAF parts (Part I: .78, Part II: .73).
    • Demonstrated construct validity through significant performance differences between junior and senior residents.
    • Structured assessment guidelines enhance reliability and validity.

    Conclusions:

    • The STSAF provides a reliable and valid method for assessing surgical technical skills.
    • Structured assessment improves the reproducibility of surgical trainee evaluations.
    • This tool can lead to enhanced and consistent feedback for surgical residents.
