Abstract
Background and objectives: Some reports suggest that older patients with traumatic brain injury (TBI) are more likely to experience acute intracranial hemorrhage, resulting in poor outcomes. However, the association between precise chronological age and use of antithrombotic agents with acute intracranial hemorrhage in these patients remains unknown. The aim of this study was to determine factors associated with acute intracranial hemorrhage and poor outcomes in patients with TBI, including chronological age and use of antithrombotic agents.
Methods: Patients hospitalized for TBI between January 2006 and December 2021 were included. Patients were categorized by age groups of <65 years, 65 to 74 years, 75 to 84 years, and ≥85 years. Associations between each age group and acute intracranial hemorrhage, a poor outcome at discharge, and in-hospital mortality were evaluated.
Results: The cohort included 1086 patients, with 713 (65.7%) in the ≥65 age group. Although chronological age was associated with acute intracranial hemorrhage in patients aged <65 years (odds ratio [OR] 1.02; 95% CI 1.01-1.03), it was not associated with patients aged ≥65 years. None of the antithrombotic agents investigated were associated with acute intracranial hemorrhage in the group aged ≥65 years. Although chronological age was associated with a poor outcome in patients aged <65 years (OR 1.03; 95% CI 1.01-1.07), it was not associated in those aged ≥65 years. The ≥85 year age group (OR 2.30; 95% CI 1.18-4.51) compared with <65 years were significantly associated with a poor outcome. None of the antithrombotic agents investigated were associated with a poor outcome in the group aged ≥65 years.
Conclusion: Our findings confirmed the lack of an association of chronological age and antithrombotic agents with acute intracranial hemorrhage in the group of older adults with TBI. Our findings suggest that antithrombotic agents may be safely used, even in older adults.
