Summary
This study evaluated a new competency assessment tool for laparoscopic cholecystectomy, finding it objective and reliable between live and video raters. The tool aids in surgical skill evaluation for residents.
Area of Science:
- Surgical Education
- Medical Simulation
- Competency-Based Assessment
Background:
- Surgical training requires robust methods to assess proficiency.
- Laparoscopic cholecystectomy is a common procedure for resident training.
- Evaluating surgical skills objectively is crucial for patient safety.
Purpose of the Study:
- To assess the inter-rater reliability of a novel competency assessment tool for laparoscopic cholecystectomy.
- To compare live surgical assessments with video-recorded assessments.
- To determine the objectivity of the assessment tool in a residency program.
Main Methods:
- A competency assessment tool was applied to residents performing laparoscopic cholecystectomies.
- Supervising surgeons (live reviewers) and blinded independent reviewers (video) assessed resident performance.
- Assessments included a specific tool (LCAT), Objective Structured Assessment of Technical Skills (OSATS), and Visual Analogue Scale (VAS).
Main Results:
- Scoring was comparable between live and video reviewers, with exceptions in OSATS and VAS components.
- Significant differences were noted in OSATS and VAS scores between live reviewers and video reviewer B, and between video reviewers A and B.
- These variations highlight potential areas for refinement in the assessment tool's application.
Conclusions:
- The developed competency assessment tool demonstrates objectivity and comparability across different raters (live vs. video).
- The tool effectively evaluates surgical skills specific to laparoscopic cholecystectomy.
- Further analysis of OSATS and VAS components may enhance inter-rater reliability.
