Abstract

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.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.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: r(s) = 0.80, P < 0.001; crisis: r(s) = 0.85, P < 0.001). Inter-rater reliability was high (alpha > or = 0.80 for all scales).High-fidelity simulation offers competency-based assessment for all grades and may provide a useful training environment for junior trainees and more experienced surgeons.
