Summary
Video replay in simulation-based vascular anastomosis training significantly improves surgical residents' technical skills. Residents tend to underestimate their performance compared to faculty evaluations, and this method may reduce gender bias in assessments.
Area of Science:
- Medical Education
- Surgical Skills Training
- Vascular Surgery
Background:
- Simulation-based training is crucial for developing surgical skills.
- Objective evaluation of technical proficiency and potential biases in assessment are critical areas in surgical education.
Purpose of the Study:
- To assess the impact of video replay in simulation-based vascular anastomosis training.
- To evaluate technical skill acquisition, self-assessment versus faculty evaluation alignment, and evaluator bias reduction.
Main Methods:
- 31 general surgery residents underwent a 7-week vascular anastomosis training program with video-recorded pre- and post-tests.
- Performance was evaluated by blinded faculty using modified MOSAT and GRS, alongside resident self-assessments.
- Paired and unpaired t-tests were used for statistical analysis.
Main Results:
- Significant improvements in both self-assessed and faculty-assessed technical scores were observed (p < 0.0001).
- Mean leak volume decreased significantly (p < 0.0001), while completion time showed no significant change.
- Post-training, faculty rated residents higher than self-assessments, and initial gender-based evaluation bias was reduced post-training.
Conclusions:
- Blinded video replay in simulation-based vascular training enhances technical skills.
- Residents tend to underestimate their abilities, highlighting a discrepancy between self and faculty assessments.
- This training modality shows potential for reducing gender-based evaluation bias in surgical training.
