Higher procedural volume predicts better trauma care outcomes.

• High-volume trauma centers (3.7% mortality) significantly outperform low-volume centers (5.4%) on mortality, p<0.001.
• Major complication rates are also lower in high-volume centers (3.1%) compared to low-volume (8.1%), p<0.001.

Surgeons should focus on procedural volume for better patient outcomes.

• Centers grouped by total trauma volume showed the opposite trends for mortality and complications, indicating a need to revise trauma center verification criteria.
