A structured simulation-based curriculum significantly boosts surgical residents’ confidence in trauma procedures, addressing gaps in traditional training.

• 364 residents showed notable improvements in self-reported confidence across six trauma procedures, with p < .001 indicating strong statistical significance.
• The incorporation of an iterative curriculum refinement process based on feedback ensured consistent positive training outcomes.

Surgeons should consider the benefits of simulation training in enhancing resident preparedness for trauma scenarios, which may translate to better performance in real-world situations.
