Age impacts the explanatory power of trauma mortality models.

Findings indicate that the explanatory power of trauma mortality models decreases linearly with age, significantly affecting objective comparisons of outcomes. Among 317,136 patients analyzed, the relative utility of covariates like Glasgow Coma Scale and Injury Severity Score varies across age groups, highlighting limitations in current adjustment models for older adults. Researchers emphasize the need for additional studies to identify effective covariates that improve model performance for all age groups.
