Development of assessing generic and specific technical skills in laparoscopic surgery

Area of Science:

• Surgical Education
• Medical Assessment
• Minimally Invasive Surgery

Background:

• Objective assessment of live laparoscopic surgery skills is underdeveloped.
• Structured methodology can reduce bias and subjectivity in surgical skill evaluation.
• Critique of a novel assessment tool for laparoscopic surgery technical skills.

Purpose of the Study:

• To develop and evaluate a new assessment tool for technical skills in live laparoscopic surgery.
• To assess the validity and reliability of the tool for both generic and specific skills.
• To address the need for objective performance metrics in surgical training.

Main Methods:

• Hierarchical task analysis of laparoscopic cholecystectomy (LC).
• Development of a global assessment tool for generic and specific LC technical skills.
• Blind and independent assessment of 50 LC operations by two experienced surgeons.

Main Results:

• High interrater reliability (k=0.86 for generic, k=0.84 for specific skills).
• Significant differences in operative time between consultant (32 min) and registrar (53 min) surgeons (P < .05).
• Significant differences in generic and specific technical skills between surgeon groups (P < .05).

Conclusions:

• The developed assessment tool shows potential for face, content, concurrent, construct, and predictive validity.
• The tool is reliable for assessing both generic and specific technical skills in live laparoscopic surgery.
• Further studies will expand the tool's application to other surgical techniques.
