The impact of peer-assisted learning combined with scenario simulation on the trauma first aid skills and comprehensive abilities of emergency department interns

Background This study aims to investigate the efficacy of peer-assisted learning amalgamated with scenario simulation in enhancing the trauma first aid competencies and holistic abilities of emergency department interns. Methods Ninety interns received blended training integrating peer-assisted learning with scenario simulation (experimental group), while 90 interns from the previous year underwent traditional instructor-led training (control group). Both groups completed 10 sessions over 4 weeks, with equivalent total instructional time. Trauma first aid performance and clinical comprehensive abilities were compared between groups and within the experimental group before and after training. Results Before training, no significant differences were observed between the two groups in any assessment items ( p > 0.05). After training, the experimental group achieved significantly higher scores in hemostatic bandaging, fracture fixation, spinal injury management, and team cooperation (all p < 0.05), while differences in cardiopulmonary resuscitation and defibrillation remained non-significant. Within the experimental group, all procedure scores improved markedly after training ( p < 0.05). Clinical comprehensive ability scores, including critical, systemic, and evidence-based thinking, were also higher than those of the control group ( p < 0.05). Conclusion Integrating peer-assisted learning with scenario simulation enhances trauma first aid performance and clinical reasoning among emergency department interns. This blended approach promotes teamwork, communication, and decision-making, providing a practical and effective framework for emergency medical education.
