The PAR-Diagonal Operating Matrix (PAR-DOM) offers objective surgical skill assessment for vascular anastomosis. This structured training model identifies trainee strengths and weaknesses, addressing reduced training durations.

Area of Science:

  • Surgical Education
  • Medical Training Assessment
  • Vascular Surgery Skills

Background:

  • Reduced surgical training duration necessitates structured assessment methods.
  • The European Working Time Directive (EWTD) impacts resident training hours.
  • Objective evaluation of surgical skills is crucial for competency development.

Purpose of the Study:

  • To introduce the PAR-Diagonal Operating Matrix (PAR-DOM) for objective skill assessment in vascular anastomosis.
  • To provide a structured framework for evaluating surgical trainees.
  • To identify individual strengths and weaknesses in surgical technique.

Main Methods:

  • Development of the PAR-Diagonal Operating Matrix (PAR-DOM), a 3x5 table.
  • Defining progress along x-axis (PAR - three skills per level) and y-axis (four skill levels).

  • Grading each skill from 1-3 (below average, average, above average).

    • Main Results:

    • The PAR-DOM breaks down vascular anastomosis into 15 distinct skills across four levels.
    • Skills assessed include Posture, Pick-up, Placing, Precision, and Pace.
    • The matrix visually represents trainee progress and highlights areas for improvement.

    Conclusions:

    • The PAR-DOM provides a graphic representation of trainee progress.
    • It facilitates identification of individual strengths and weaknesses in surgical skills.
    • This model supports structured surgical training and assessment in the context of reduced training durations.
