Development and Validation of a Surgical Performance Assessment Scale for Lung Lobectomy and Lymph Node Dissection.

Area of Science:

• Thoracic Surgery
• Surgical Education
• Medical Device Development

Background:

• Objective assessment tools are crucial for surgical trainee evaluation.
• Current methods may lack objectivity, reliability, and validation for lung lobectomy procedures.

Purpose of the Study:

• To develop and validate the Lung Lobectomy Performance Assessment Scale Score (LOB-PASS).
• To provide an objective tool for assessing lung lobectomy performance, including lymph node dissection, across various surgical approaches.

Main Methods:

• The LOB-PASS was developed using the Delphi method and response process testing in simulations.
• Validation involved 48 residents assessed by independent observers using simulation-based testing.
• Internal structure and inter-observer reliability were statistically analyzed.

Main Results:

• The LOB-PASS comprises 52 items across seven domains, totaling 104 points.
• High internal consistency (Cronbach's alpha=0.89) and reliability (ICC=0.92) were demonstrated.
• No significant inter-observer differences were found, indicating consistent scoring.

Conclusions:

• LOB-PASS is a valid and reliable instrument for evaluating lung lobectomy performance, including lymph node dissection.
• Incorporating LOB-PASS into training can standardize competency assessment and improve technical skill acquisition in thoracic surgery.
