Methods
This was a single-center, retrospective chart review of 661 patients. Inclusion criteria were consecutive patients with hemorrhagic mild TBI. Exclusion criteria were any other acute traumatic injury and significant comorbidities. Variables recorded included neurosurgical intervention and timing, mortality, emergency room disposition, intensive care unit (ICU) length of stay (LOS), discharge disposition, repeat computed tomography head (CTH) indications and results, neurologic exam, age, sex, Glasgow Coma Scale (GCS) score, and hemorrhage type.
Results
Overall intervention and unexpected delayed intervention rates were 9.4% and 1.5%, respectively. The mortality rate was 2.4%. A 10-year age increase had 26% greater odds of intervention (95% CI, 9.6-45%; P<. 001) and 53% greater odds of mortality (95% CI, 11-110%; P=. 009). A one-point GCS increase had 49% lower odds of intervention (95% CI, 25-66%; P<. 001) and 50% lower odds of mortality (95% CI, 1-75%; P=. 047). Subdural and epidural hemorrhages were more likely to require intervention (P=. 02). ICU admission was associated with discharge to an acute care facility (OR, 2.9; 95% CI, 1.4-6.0; P=. 003). Neurologic exam changes were associated with a worsened CTH scan (OR, 12.3; 95% CI, 7.0-21.4; P<. 001) and intervention (OR, 15.1; 95% CI, 8.4-27.2; P<. 001).
Conclusions
Isolated hemorrhagic mild TBI patients are at a low, but not clinically insignificant, risk of intervention and mortality.
