ObjectivesHealthcare evolution requires optimisation of surgical training to provide safe patient care. Operating room performance after completion of proficiency based training in vascular surgery has not been investigated.DesignA randomised controlled trial evaluated the impact of a Proficiency based Stepwise Endovascular Curricular Training program (PROSPECT) on the acquisition of endovascular skills and the transferability of these skills to real life interventions.MaterialsAll subjects performed two endovascular interventions treating patients with symptomatic iliac and/or superficial femoral artery stenosis under supervision. Primary outcomes were technical performances (Global Rating Scale [GRS]; Examiner Checklist), operative metrics, and patient outcomes, adjusted for case difficulty and trainee experience. Secondary outcomes included knowledge and technical performance after 6 weeks and 3 months.MethodsThirty-two general surgical trainees were randomised into three groups. Besides traditional training, the first group (n = 11) received e-learning and simulation training (PROSPECT), the second group (n = 10) only had access to e-learning, while controls (n = 11) did not receive supplementary training.ResultsTwenty-nine trainees (3 dropouts) performed 58 procedures. Trainees who completed PROSPECT showed superior technical performance (GRS 39.36 ± 2.05; Checklist 63.51 ± 3.18) in real life with significantly fewer supervisor takeovers compared with trainees receiving e-learning alone (GRS 28.42 ± 2.15; p = .001; Checklist 53.63 ± 3.34; p = .027) or traditional education (GRS 23.09 ± 2.18; p = .001; Checklist 38.72 ± 3.38; p = .001). Supervisors felt more confident in allowing PROSPECT trained physicians to perform basic (p = .006) and complex (p = .003) procedures. No differences were detected in procedural parameters (such as fluoroscopy time, DAP, procedure time, etc.) or complications. Proficiency levels were maintained up to 3 months.ConclusionsA structured, stepwise, proficiency based endovascular curriculum including e-learning and simulation based training should be integrated early into training programs to enhance trainee performance.
