Retrospective analysis shows rising mortality in trauma patients with ARDS on mechanical ventilation, indicating key risk factors to address.

To characterize trends in ARDS frequency and its impact on mortality in trauma patients on mechanical ventilation from 2007 to 2019.
Retrospective cohort study of patients from the American College of Surgeons National Trauma Data Bank.
Included trauma patients aged 18+ on mechanical ventilation for ≥2 days from 2007 to 2019.
Logistic regression models adjusted for demographics and center characteristics to assess ARDS diagnosis and 30-day mortality.
ARDS was noted in 29,359 of 384,032 patients on MV (8%).
Mortality of ARDS patients rose from 15.1% in 2007 to 29.7% in 2019, p < 0.001.
Key risk factors for ARDS included blunt injury, severe sepsis, and ventilator-associated pneumonia.
