Acute predictors for mortality after severe TBI in Spain: Gender differences and clinical data

Area of Science:

• Neuroscience
• Trauma Care
• Public Health

Background:

• Severe traumatic brain injury (TBI) is a significant cause of mortality and long-term disability.
• Understanding factors influencing TBI outcomes is crucial for improving patient care and prognosis.
• Previous research has yielded conflicting results regarding the impact of gender on TBI outcomes.

Purpose of the Study:

• To investigate the influence of gender on global mortality and functional outcomes in patients with severe traumatic brain injury (TBI).
• To identify potential gender-specific differences in TBI patient characteristics and outcomes.

Main Methods:

• A retrospective cohort study of 629 patients with severe TBI admitted to an intensive care unit (ICU).
• Patients were analyzed based on gender, comparing mortality and functional outcomes (using the Glasgow Outcome Scale) at ICU discharge and 6 months post-trauma.
• Variables analyzed included injury severity, secondary brain injury factors, and demographic data.

Main Results:

• Women exhibited higher APACHE II scores and increased incidence of pre-hospital hypotension and anemia.
• Higher mortality rates were observed in women at the ICU and 6-month follow-up, but gender was not an independent predictor in multivariate analysis.
• No significant differences in functional outcomes were found between genders at ICU discharge or 6 months post-injury.

Conclusions:

• Gender was not identified as an independent predictor of poorer outcomes in severe traumatic brain injury (TBI).
• Despite observed differences in initial severity and mortality, functional recovery did not significantly differ by gender.
• Further research may explore other factors contributing to TBI outcomes beyond gender.
