BackgroundAs end-stage renal disease becomes more prevalent in the United States, the number of Americans with arteriovenous (AV) fistulas continues to increase. One of the most feared complications of AV fistulas is life-threatening hemorrhage, as patients can exsanguinate within minutes.ObjectivesAs frontline healthcare workers, emergency medicine (EM) providers need to be able to provide rapid and effective treatment for this rare presentation. We developed a task trainer model to simulate AV fistula hemorrhage to prepare and train EM residents.MethodsThis task trainer model was constructed with readily available materials and takes about 30 minutes to make. Twenty-one EM residents participated in the training session. The session consisted of a brief didactic on AV fistula hemorrhage control followed by hands on usage of the task-trainer model. The participants filled out an anonymous survey afterwards rating the model.ResultsResidents completed anonymous postcourse surveys rating the session on a five-point Likert scale. Both the overall teaching session and the task trainer were rated very highly. Compared to precourse ratings, residents reported statistically significant postcourse improvements in their level of confidence in managing AV fistula hemorrhage.ConclusionsTo our knowledge, this is the first published task trainer model to simulate a bleeding AV fistula for EM residents. The model was well received by our trainees, is relatively inexpensive, and made from easily sourced materials. We believe this model can be used for trainees of all disciplines to prepare them for this potentially catastrophic patient presentation.Copyright © 2024 Elsevier Inc. All rights reserved.
