Letter to the editor: Effect of low fibrinogen level on in-hospital mortality and 6-month functional outcome of TBI patients, a single center experience, the retrospective cohort study.

This retrospective cohort study aimed to investigate the impact of low fibrinogen levels on in-hospital mortality and 6-month functional outcomes in patients with traumatic brain injury (TBI) within a single center,focusing on the strengths, weaknesses, and suggestions for future research. Patients were followed up to assess in-hospital mortality and functional outcomes at six months post-injury using standardized scales. Statistical analyses, including multivariable regression models, were employed to evaluate the association between low fibrinogen levels and outcomes, adjusting for potential confounders, and revealed a significant association between low fibrinogen levels and increased in-hospital mortality rates among patients with TBI (p < 0.05). Additionally, patients with low fibrinogen levels exhibited poorer functional outcomes at the 6-month follow-up, as evidenced by lower scores on functional assessment scales than those with normal fibrinogen levels, suggesting that low fibrinogen levels upon admission may serve as a prognostic indicator for adverse outcomes in patients with TBI, including higher in-hospital mortality rates and impaired functional recovery at 6 months post-injury. Furthermore, this study explored conservative and surgical management approaches, offering valuable insights into treatment decision-making and outcomes. Future research should prioritize prospective, multicenter studies with standardized protocols, collaborative efforts among institutions, and innovative techniques to advance our understanding and management.
