Remote training and evaluation of asimulator-based training course for complex endovascular procedures.

Abstract

Intimate knowledge of the materials used in endovascular aortic interventions is essential for trainees and supporting staff taking part in an endovascular intervention. Training courses can help to familiarize trainees with the equipment. However, the pandemic has changed the landscape of hands-on training courses significantly. Therefore, we developed atraining course including an educational recording of the procedure to transfer knowledge about the materials used during endovascular interventions and radiation exposure reduction. We produced avideo depicting cannulation of the left renal artery in asilicon cast of an aorta and its major side branches under C‑arm fluoroscopy. Apresentation using the video was given to the trainees. The trainees were randomized into acontrol and an intervention group. Their performance was filmed and rated on astandardized five-point scale in the style of the OSATS global rating scale. The intervention group was remeasured after additional training time. In total, 23trainees participated in the training and agreed to have their performance recorded. The control and intervention groups showed no difference in the assessed performance metrics during their initial attempt. However, after receiving additional training, the intervention group significantly improved in all evaluated metrics. Our data add to the growing evidence that simulator-based training can help to increase trainees' understanding and performance of relevant skills. Astandardized and evidence-based validation process for simulators could improve their acceptance in the medical field.
