• Training is required for all doctors new to REBOA regardless of existing vascular access skills and simpler catheter systems. • Doctors skilled in vascular access benefit from an initial inter-procedural transfer of skills effect when first learning REBOA. • However, novice doctors perform equally well after a focussed simulation-based training, indicating that either group can learn the technical aspects of inserting REBOA. • A time-fixed simulation-based training program does not ensure technical proficiency of doctors learning REBOA, despite vast experience. • Individual skills assessment should be used to ensure proficiency following training for all doctors regardless of previous experience. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging and potentially life-saving procedure, necessitating qualified operators in an increasing number of centres. The procedure shares technical elements with other vascular access procedures using the Seldinger technique, which is mastered by doctors not only in endovascular specialties but also in trauma surgery, emergency medicine, and anaesthesiology. We hypothesised that doctors mastering the Seldinger technique (experienced anaesthesiologist) would learn the technical aspects of REBOA with limited training and remain technically superior to doctors unfamiliar with the Seldinger technique (novice residents) given similar training. This was a prospective trial of an educational intervention. Three groups of doctors were enroled: novice residents, experienced anaesthesiologists, and endovascular experts. The novices and the anaesthesiologists completed 2.5 h of simulation-based REBOA training. Their skills were tested before and 8–12 weeks after training using a standardised simulated scenario. The endovascular experts, constituting a reference group, were equivalently tested. All performances were video recorded and rated by three blinded experts using a validated assessment tool for REBOA (REBOA-RATE). Performances were compared between groups and with a previously published pass/fail cutoff. Sixteen novices, 13 board-certified specialists in anaesthesiology, and 13 endovascular experts participated. Before training, the anaesthesiologists outperformed the novices by 30 percentage points of the maximum REBOA-RATE score (56% (SD 14.0) vs 26% (SD 17%), p <0.01). After training, there was no difference in skills between the two groups (78% (SD 11%) vs 78 (SD 14%), p = 0.93). Neither group reached the endovascular experts' skill level (89% (SD 7%), p <0.05). For doctors mastering the Seldinger technique, there was an initial inter-procedural transfer of skills advantage when performing REBOA. However, after identical simulation-based training, novices performed equally well to anaesthesiologists, indicating that vascular access experience is not a prerequisite to learning the technical aspects of REBOA. Both groups would need more training to reach technical proficiency. [ABSTRACT FROM AUTHOR]

Summary: Trauma accounts for approximately 1 in 10 deaths worldwide. The presence of a pelvic fracture increases this mortality risk. Successful management depends on accurate diagnostic staging and control of fracture-related haemorrhage. From the standpoint of the trauma surgeon, this necessitates thorough compression and stabilisation of the fracture using external compression, combined with retroperitoneal or preperitoneal packing. However, vascular injury in many parts of the body can preferentially and effectively be treated on an emergency basis with angiographic procedures, using superselective embolisation in combination with other interventional techniques. The option of combining open surgery and angiographic methods should be kept in mind, but there are no uniform guidelines. In the literature, numerous studies and reports have documented the feasibility of interventional radiological procedures in trauma cases with pelvic fracture. Thus all level I trauma centres should be able to provide this service on a 24h basis. [Copyright &y& Elsevier]

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potentially life-saving but high-risk emergency procedure in patients with haemorrhagic shock. Lack of physicians with competence in the procedure is a barrier to implementation of REBOA. It is currently unclear how training and assessment of competence should be done.Objectives: To report and evaluate research in training and assessment of competence in REBOA and femoral arterial access with the aim to investigate the effect of simulation-based training in the procedure and to provide suggestions for the future design of training programs and assessment tools.Methods: Following PRISMA guidelines, PubMed, Embase, and Cochrane Library databases were searched for studies on training or assessment of competence in REBOA and femoral arterial access. Bias assessment was done using the Medical Education Research Study Quality Instrument. Evidence level was assessed using GRADE.Results: Sixteen studies were included, six of them published as abstracts. Full-text studies included 189 trainees ranging in experience level from military medics to surgical specialists. Outcome measures were heterogenous; the most used were rater checklists, knowledge testing, and procedure time. All studies confirmed an effect of training of REBOA on procedural competence in a simulation setting but had a high degree of bias. No study developed or used an assessment tool supported by validity evidence and no study investigated mid and long-term outcomes.Conclusion: Simulation-based training of REBOA improves skills, however, the evidence level is very low and data cannot answer important questions on effect size, skill transfer and retention, and optimal course design. To advance research and training programmes, an assessment tool supported by validity evidence with broad applicability is needed. [ABSTRACT FROM AUTHOR]
