SDH >8 mm Has Highest Association With In-Hospital Mortality

Background: Traumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide, but only limited studies have examined how specific TBI subtypes, including subdural hematoma (SDH), subarachnoid hemorrhage (SAH), epidural hemorrhage (EDH), diffuse axonal injury (DAI), and contusions—affect important outcomes such as in-hospital mortality, ICU length of stay (LOS), and ventilation duration. Objective: To evaluate the impact of TBI subtype and size on clinical outcomes, including in-hospital mortality, ICU LOS, and ventilation days, in adult patients with isolated blunt TBI and skull fractures. Design: Retrospective cohort study. Participants/Methods: The study analyzed 64,111 patients TBI subtype, size, demographics, comorbidities, and injury characteristics in patients aged ≥ 15 years with isolated blunt TBI and skull fractures at a single institution. Polytrauma cases were excluded. Results: SDH >8 mm had the highest association with in-hospital mortality. Larger S more...
