Background

Methods of surgical training that do not put patients at risk are desirable. A high‐fidelity simulation of carotid endarterectomy under local anaesthesia was tested as a tool for assessment of vascular surgical competence, as an adjunct to training.

Method

Sixty procedures were performed by 30 vascular surgeons (ten junior trainees, ten senior trainees and ten consultants) in a simulated operating theatre. Each performed in a non‐crisis scenario followed by a crisis scenario. Performance was assessed live by means of rating scales for technical and non‐technical skills.

Results

There was a significant difference in technical skills with ascending grade for both generic and procedure‐specific technical skill scores in both scenarios (P < 0·001 for all comparisons). Similarly, there was also a significant difference in non‐technical skill with ascending grade for both scenarios (P < 0·001). There was a highly significant correlation between technical and non‐technical performance in both scenarios (non‐crisis: rs = 0·80, P < 0·001; crisis: rs = 0·85, P < 0·001). Inter‐rater reliability was high (α≥ 0·80 for all scales).

Conclusion

High‐fidelity simulation offers competency‐based assessment for all grades and may provide a useful training environment for junior trainees and more experienced surgeons. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
