Traumatic Brain Injury Research Reveals Prognostic Marker for Mortality

Strategic Insights

— 1 min read

Research from Chang Gung University, published in the journal Diagnostics, has identified a predictive indicator for mortality in patients with moderate-to-severe traumatic brain injury. The study analyzed data from 4,415 patients and found that an initial De Ritis ratio of 1.64, a measure of liver enzyme levels, was associated with a significantly higher mortality rate compared to patients with a De Ritis ratio of 1.2. The research suggests that the De Ritis ratio could serve as an independent predictor of mortality in TBI patients, providing valuable prognostic information for early risk stratification.

Key Takeaways:

  • The study analyzed data from 4,415 adult patients with moderate-to-severe TBI (head/neck AIS 3) from January 2009 to December 2020.
  • Patients were categorized into three groups based on De Ritis ratios: 1.2 (n = 1296), 1.2-1.64 (n = 1620), and 1.64 (n = 799).
  • Propensity score matching was performed to adjust for baseline characteristics, including age, sex, comorbidities, Glasgow Coma Scale, and Injury Severity Score.
  • Higher De Ritis ratios were associated with increased intensive care unit admission rates and longer hospital stays.
  • Patients with De Ritis ratio 1.64 showed significantly higher mortality rates compared to the control group (10.3% vs. 7.9%, odds ratio (OR) = 1.33, 95% confidence interval (CI) 1.01-1.77, p = 0.046).
  • The study's findings suggest that the De Ritis ratio could serve as an independent predictor of mortality in moderate-to-severe TBI patients.

Statistics:

  • 4,415 adult patients with moderate-to-severe TBI were analyzed in the study.
  • 1296 patients had a De Ritis ratio of 1.2.
  • 1620 patients had a De Ritis ratio of 1.2-1.64.
  • 799 patients had a De Ritis ratio of 1.64.
  • Mortality rate for patients with De Ritis ratio 1.64 was 10.3% compared to 7.9% in the control group.
  • Odds ratio (OR) for mortality with De Ritis ratio 1.64 was 1.33 (95% CI 1.01-1.77, p = 0.046).
