Subcutaneous Adipose Tissue Radiation Attenuation Is Associated With Increased 1-Year Mortality in Polytrauma Patients.

ABSTRACT:

Background

Polytrauma patients with an Injury Severity Score (ISS) ≥ 16 have a high mortality rate. Early identification of patients at risk of mortality is key. Different risk stratification models are available; however, body composition on third lumbar computed tomography (L3 CT) is not routinely used. The aim of this study is to determine the effect of CT body composition on 1-year mortality in adult polytrauma patients.

Methods

Body composition analysis (L3 CT) was performed on 593 adult polytrauma patients. The associations with 1-year mortality were assessed using uni- and multivariable logistic regression analysis. As a sensitivity analysis, 1-year mortality was analysed using Kaplan-Meier survival curves, log-rank tests and Cox regression.
