High-fidelity trauma simulation significantly boosts communication and teamwork among surgical teams, impacting patient safety and outcomes.

• Confidence in communication improved from 3.67 to 4.51 (p < .001) across two scenarios.
• 88% of participants stated simulation influenced their future communication practices, focusing on active listening and status updates.

Integrating these simulations into training may enhance OR efficiency and quality of care.

• Perceived role importance rose notably for nurses (59%) and anesthesiologists (49%).
