Predicting Traumatic Brain Injury Outcomes: The Intersection of Clinical Signs, Laboratory Indicators and Radiology

Area of Science:

• Neuroscience
• Critical Care Medicine
• Trauma Surgery

Background:

• Traumatic brain injury (TBI) is a leading cause of death and disability worldwide.
• Identifying prognostic factors in TBI is essential for effective patient management and resource allocation.

Purpose of the Study:

• To evaluate clinical, radiological, and laboratory factors associated with poor outcomes in TBI patients.
• To determine the predictive value of various parameters for mortality and functional recovery in TBI.

Main Methods:

• Prospective observational study of 80 TBI patients followed for 6 months.
• Assessment of admission parameters including vital signs, Glasgow Coma Scale (GCS), pupillary reactivity, CT findings (Marshall grade), and laboratory tests.
• Statistical analysis using chi-squared test and Haldane-Anscombe correction to correlate factors with outcome (ICU mortality, Glasgow Outcome Scale).

Main Results:

• Univariate analysis identified hypoxemia, tachycardia, low GCS, non-reactive pupils, hypernatremia, and Marshall grade IV as associated with poor outcomes (p<0.05).
• Multivariate analysis revealed low GCS, non-reactive pupils, and hypoxemia as significant independent predictors of poor outcome.
• Low GCS also correlated with prolonged hospital stay and unfavorable Glasgow Outcome Scale (GOS) scores (I-III).

Conclusions:

• Low GCS, hypoxemia, non-reactive pupils, tachycardia, hypernatremia, and Marshall grade IV are critical indicators of poor prognosis in TBI.
• These findings emphasize the importance of preventing secondary brain injury and optimizing triage strategies for TBI patients.
• Timely recognition of these factors can guide clinical decision-making and potentially improve patient outcomes.
