The following is a summary of “Development of a bleeding arteriovenous fistula task trainer,” published in the November 2024 issue of Emergency Medicine by Pauw and Walsh.
The increasing prevalence of end-stage renal disease in the United States led to a rise in arteriovenous (AV) fistulas, which posed a significant risk of life-threatening hemorrhage due to rapid exsanguination.
Researchers conducted a retrospective study to assess the use of a task trainer model to prepare emergency medicine (EM) residents to manage AV fistula hemorrhage.
They constructed the task trainer model using easily accessible materials, requiring approximately 30 minutes to complete, 21 EM residents participated in the session, which began with a brief didactic on AV fistula hemorrhage control. Following the lecture, participants engaged in hands-on practice using the model. After the session was completed, an anonymous survey was done to evaluate the task trainer.
The results showed that residents completed anonymous post-course surveys, rating the session and task trainer using a five-point Likert scale. The overall teaching session and the task trainer received high ratings while the post-course ratings indicated significant improvements in confidence levels for managing AV fistula hemorrhage compared to pre-course assessments.
Investigators concluded the novel task trainer model effectively simulated a bleeding AV fistula, offering a valuable training tool for EM residents and potentially other healthcare professionals.
