Overview

Retrospective analysis shows BMI affects outcomes in trauma patients, suggesting a need for careful assessment in ICU.

Key Points

  • This research investigates how body mass index (BMI) influences intensive care outcomes for severely injured patients.
  • Retrospective matched 1:2:1 analysis using data from the TraumaRegister DGU®
  • Included 5,766 patients categorized into underweight, normal weight/overweight, and obese groups
  • Subgroup analysis of 272 polytraumatized patients
  • Measured outcomes included duration of mechanical ventilation, ICU stay, organ failure, and in-hospital mortality
  • Higher BMI was linked to increased organ failure, particularly cardiac and pulmonary (p = 0.001)
  • Obese patients had a mortality rate of 10.4%, compared to 5.2% in underweight patients (p = 0.025)
  • Mechanical ventilation time significantly increased with higher BMI (p = 0.012)
