Abstract

The De Ritis ratio is widely used to differentiate various causes of liver disease and serves as an independent prognostic predictor for different malignancies and non-malignant illnesses. This retrospective study aimed to identify the association between the De Ritis ratio on admission and mortality outcomes in adult thoracoabdominal trauma patients. A total of 2248 hospitalized adult trauma patients with thoracoabdominal injury, defined as an abbreviated injury scale (AIS) score ≥ 1 in the thoracic and abdominal regions, between 1 January 2009, and 31 December 2019, were included. They were categorized into three tertile groups according to the De Ritis ratio. A 1:1 propensity score-matched study group was established to attenuate the confounding effect of patient characteristics on the mortality outcome assessment. The AST levels of the tertile 1, 2, and 3 groups were 115.8 ± 174.9, 115.7 ± 262.0, and 140.5 ± 209.7 U/L, respectively. Patients in the tertile 3 group had a significantly higher level of AST than those in the tertile 1 group (p = 0.032). In addition, patients in the tertile 1 group had a significantly higher level of ALT than those in the tertile 2 and 3 groups (115.9 ± 158.1 U/L vs. 74.5 ± 107.0 U/L and 61.9 ± 86.0 U/L, p < 0.001). The increased De Ritis ratio in trauma patients with thoracoabdominal injuries was mainly attributed to elevated AST levels. The propensity score-matched patient cohorts revealed that the patients in the tertile 3 group presented a 3.89-fold higher risk of mortality than the patients in the tertile 2 group. In contrast, the patients in the tertile 1 group did not have a significantly different mortality rate than those in the tertile 2 group. This study suggests that a De Ritis ratio > 1.64 may be a useful biomarker to identify patients with a higher risk for mortality.
