Multicenter Cohort Study to Evaluate the Relationship between Radiological Findings and Disability in Moderate and...

Area of Science:

• Neurosurgery
• Traumatology
• Radiology

Background:

• Head injuries present a significant global health challenge, with varying outcomes.
• Radiological findings are crucial for classifying head injury severity and type.
• Understanding the relationship between imaging and patient prognosis is vital for effective management.

Purpose of the Study:

• To investigate the correlation between radiological findings and patient disability after moderate to severe head injuries.
• To compare outcomes across different classifications of traumatic brain injury based on imaging.
• To assess the impact of injury patterns on patient recovery and mortality.

Main Methods:

• A multicenter cohort study involving 104 patients over 36 months.
• Participants were categorized into three groups based on radiological findings: diffused traumatic brain injury (arm-1), focal traumatic brain injury (arm-2), and combined diffused and focal traumatic brain injury (arm-3).
• Patient outcomes were evaluated using the modified Rankin Score (mRS), assessing improvement, lack of improvement, and mortality.

Main Results:

• The overall mean age of participants was 40.28 years, with a higher mean age observed in females.
• A significantly higher proportion of patients showed improvement compared to those who did not improve or died (p<0.00001).
• Improved outcomes were significantly more frequent in patients with diffused (arm-1) and focal (arm-2) traumatic brain injuries. Mortality rates were significantly higher in the combined injury group (arm-3) (p<0.00001).

Conclusions:

• Radiological classification of traumatic brain injury is strongly associated with patient outcomes.
• Patients with isolated diffused or focal brain injuries tend to have better prognoses than those with combined injuries.
• Early identification and management strategies tailored to injury patterns can potentially reduce mortality in severe head injury patients.
