To test the feasibility of an online, simulator-based comprehensive interventional radiology (IR) training curriculum in times of COVID-19-induced travel restrictions. A network of six VIST simulators (Mentice, Gothenburg, Sweden) was installed in six geographically different radiology departments. Two courses with six sessions each took place. 43 participants were recruited on a voluntary basis among local residents. The training sessions were conducted in real time with interconnected simulation devices and were led by experts in the field of IR on a rotational basis.
Endovascular simulation is a validated training method, allowing residents to improve technical skills with interventional equipment in a risk-free environment. The purpose of this study was to assess the utility and efficacy of supplementing the IR/DR Integrated Residency training program with a dedicated 2-year endovascular simulation curriculum.
To explore whether simulation-based endovascular training with focus on radiation safety could improve correct behavior without jeopardizing the learning of procedural skills.
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potentially life-saving procedure for bleeding trauma patients. Being a rare and complex procedure performed in extreme situations, repetitive training of REBOA teams is critical. Evidence-based guidelines on how to train REBOA are missing, although simulation-based training has been shown to be effective but can be costly and complex. We aimed to determine the feasibility and acceptance of REBOA training using a fully immersive virtual reality (VR) REBOA simulation, as well as assess the confidence in conducting the REBOA procedure before and after the training.
Purpose: To identify the impact of endovascular simulator training and shadowing in interventional radiology on medical students’ self-assessed IR knowledge. Moreover, the sequence of the teaching methods and its influence on the self-assessed IR knowledge is investigated. Materials and Methods A total of 19 fourth-year medical students participated in this study. Eleven students completed shadowing live cases first and endovascular simulator training the following day. Eight students completed the teaching in reversed order. Questionnaires were completed before and after each teaching method. The students assessed their knowledge of instruments and materials, steps of the Seldinger technique, and aortography on a Likert scale (1 = ‘‘I do not agree at all,’’ 5 = ‘‘I fully agree’’). Results After simulator training, the students stated a significant increase in perceived knowledge compared with baseline (p\0.001). Shadowing led to a significant improvement regarding the items ‘‘knowledge of instruments and materials’’ (3.2 vs. 3.8, p = 0.008) and ‘‘steps of the Seldinger technique’’ (3.7 vs. 3.9, p = 0.046). Selfassessed knowledge after simulator training increased significantly more regarding Seldinger technique compared with shadowing (? 1.2 vs. ? 0.2, p\0.001). Simulator training before shadowing was significantly more effective regarding the increase in ‘‘knowledge of the steps of aortography’’ compared with the reverse sequence (? 2.0 vs. ? 0.9, p = 0.041). Conclusion Endovascular simulator training and shadowing are both feasible tools to improve medical students’ perceived knowledge of interventional radiology. When organizing teaching, simulator training before shadowing can have a positive impact on self-assessed knowledge.
Rehearsing endovascular aortic aneurysm repair on patient-specific data is recent within virtual reality simulation and opens up new possibilities for operators to prepare for complex procedures. This study evaluated the feasibility of patient-specific rehearsal (PsR) and assessed operators' appraisal of the VIST-LAB simulator from Mentice.
This study evaluates a fully immersive simulated angiosuite for training and assessment of technical endovascular and human factor skills during a crisis scenario.
Interventional radiology (IR) is a growing field but is underrepresented in most medical school curricula. We tested whether endovascular simulator training improves medical students' attitudes towards IR.
Simulator-based endovascular skills training measurably improves performance in catheter-based image-guided interventions. The purpose of this study was to determine whether structured global performance assessment during endovascular simulation correlated well with trainee-reported procedural skill and prior experience level.
Many aspects of medical training take place on real patients in a live environment thus incurring risk. Apart from the obvious risks to patients there is the issue of X-ray exposure to both staff and trainees. Image quality used during interventional procedures is low to ensure minimum X-ray radiation dose. A virtual interventional system may be used to simulate the interventional cardiology training environment therefore reducing overall risk.
To compare objective fellow and expert efficiency indices for an interventional radiology renal artery stenosis skill set with the use of a high-fidelity simulator.
Virtual reality (VR) simulation has been suggested to objectively assess endovascular skills. The aim of this study was to determine the impact of cognitive training on technical performance of inexperienced subjects on a commercially available VR simulator (VIST, Vascular Intervention Simulation Trainer, Mentice, Gothenburg, Sweden).
To determine the value of an angioplasty simulation to differentiate the users based on their level of experience. To determine the perceived usefulness of an angioplasty simulation program.
Patient-specific rehearsal (PsR) is a new concept whereby a procedure can be rehearsed virtually using the exact patient’s anatomical data prior to performing the real procedure. The aim of this study was to ascertain if endovascular virtual-reality PsR simulation enhanced performance in real life. This was done by performing a systematic review following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines.
