Trauma is one of the most important issues and problems considered in most countries in today's modern and industrial society. Since pre-hospital care is the first component of a trauma care system, if done properly, it can reduce the problems associated with long-term disability and death due to trauma. Therefore, the present study was conducted to determine the impact of training based on a modified team-based learning (TBL) method on the skills of medical emergency personnel in managing trauma patients in 2022. The present study was a two-group clinical before/after study in which 96 technicians were selected using a stratified random sampling method. The sample members were randomly divided into an intervention group and a control group. In the intervention group, skills for dealing with trauma patients were taught through a modified team-based learning method. The results were analyzed using SPSS software version 21. The results of the repeated measures analysis of variance showed a significant difference between the intervention and control groups in learning skills for dealing with trauma patients (P<0.001), which were determined by examining the effect of test repetition and the effect of interaction. The changes in the studied variables in the TBL groups were significantly greater than those in the control group (P<0.001). The results indicate that training based on the modified team-based learning method is effective for the management of trauma patients by medical emergency personnel and improves the readiness of personnel in this field.
