PurposeSurgical trainees are exposed to less procedures with increasing need for simulation. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has become increasingly implemented for hemorrhage control, yet most courses are catered to faculty level with little data on trainees. We propose that routine training in this critical procedure will improve trainee performance over time.MethodsThis is a prospective, observational study at a level I trauma center involving a monthly trauma procedural program. Early in the month, trainees received hands-on REBOA training; at the end, trainees underwent standardized, class-based evaluation on a perfused trainer. Score percentages were recorded (0-100%). Endpoints included early, mid and late performance (2-12 months). Paired T-test and Pearson's coefficient were used to evaluate differences and strength of association between time between training and performance.Results25 trainees participated with 5 and 11 repeat learners in the PGY-2 and PGY-3 classes, respectively. Median early performance score was 62.5% (IQR 56-81) for PGY-2s and 91.6% (IQR 75-100) in PGY-3s. Pearson's coefficient between time between and training and score demonstrated a weak correlation in the PGY-2s (r2 = - 0.13), but was more pronounced in the PGY-3s (r2 = - 0.44) with an inflection point at 5 months.ConclusionsRoutine REBOA training in trainees is associated with improvement in performance within a short period of time. Skill degradation was most pronounced in trainees who did not receive training for more than 5 months. Trainees can be successfully trained in REBOA; however, this should be done at shorter intervals to prevent skill degradation.© 2021.
