Abstract
In a changing learning environment where young neurointerventionalists spend less time in the operating room, computer simulators have been established as a new training model. Our aim was the comparison of silicone models and computer simulators, and the evaluation of their influence on subjective self-confidence of operators. Pre- and postquestionnaires of 27 participants and 9 tutors were evaluated after the participation in a three-days interventional stroke course using silicone models and computer simulators. Training on computer simulators was considered as more realistic and important before patient contact than training on silicone models. Participants rated their own abilities as significantly better after participation in the course and felt significantly better prepared for patient care. Training on computer simulators can increase the subjective self-confidence of trainees. We suggest a stepwise training program, comprising both ex-vivo and the porcine in-vivo model, finished by conventional operating room teaching, to prepare neuroradiologists for optimal patient care when performing interventions.
Highlights
Ischaemic stroke is one of the most frequent causes of death worldwide [1]
We found a significant difference within the group of participants (p = 0.008), when we compared how important they assessed the training on silicone models or computer simulators before doing thrombectomies in humans
Our results show that training on silicone models and computer simulators is considered to be useful before patient care
Summary
Ischaemic stroke is one of the most frequent causes of death worldwide [1]. Endovascular stroke therapy has been established as the standard treatment option for emergent large vessel occlusion stroke. Treatment has become more effective, and more complex, necessitating more efficient training. Practical training of young neurointerventionalists took place in the operating room. The aim of increasing patient safety and increased complexity of neurointerventional procedures have led to the development of new training methods [2,3,4]. A major advantage of ex-vivo models is patient safety, as mistakes remain without clinical consequence [5,6,7]. The most common training programs for neurointerventionalists consist of training on silicone and animal models.
