Insights
Children with bleeding disorders had higher computerized tomography (CT) use after head trauma, but traumatic intracranial hemorrhage (ICH) was rare (1.1%). Routine CT may not be necessary for asymptomatic children with bleeding disorders.
Area of Science:
- Pediatric Emergency Medicine
- Neurotrauma
- Hematology
Background:
- Blunt head trauma in children necessitates careful evaluation for traumatic intracranial hemorrhage (ICH).
- Children with congenital and acquired bleeding disorders may be at increased risk for ICH, influencing diagnostic decisions.
Purpose of the Study:
- To compare computerized tomography (CT) utilization and the prevalence of traumatic intracranial hemorrhage (ICH) in pediatric patients with and without bleeding disorders following blunt head trauma.
Main Methods:
- A multicenter cohort study included 43,904 children under 18 years old with blunt head trauma evaluated in 25 emergency departments.
- CT use and ICH prevalence were compared between children with (n=230) and without bleeding disorders, controlling for Glasgow Coma Scale (GCS) scores.
Main Results:
- Children with bleeding disorders had significantly higher CT rates (Risk Ratio 2.29) compared to those without bleeding disorders, even with similar GCS scores (14-15).
- ICH prevalence was low in both groups: 1.1% in children with bleeding disorders versus 4.4% in children without bleeding disorders.
- No children with bleeding disorders and ICH required neurosurgery, and all presented with symptoms.
Conclusions:
- Despite increased CT utilization in children with bleeding disorders, traumatic intracranial hemorrhage is uncommon (1.1%) and associated with symptoms.
- Routine CT imaging may not be indicated for asymptomatic children with congenital or acquired bleeding disorders presenting after head trauma.
Objective:
To determine computerized tomography (CT) use and prevalence of traumatic intracranial hemorrhage (ICH) in children with and without congenital and acquired bleeding disorders.
Study Design:
We compared CT use and ICH prevalence in children with and without bleeding disorders in a multicenter cohort study of 43 904 children <18 years old with blunt head trauma evaluated in 25 emergency departments.
Results:
A total of 230 children had bleeding disorders; all had Glasgow Coma Scale (GCS) scores of 14 to 15. These children had higher CT rates than children without bleeding disorders and GCS scores of 14 to 15 (risk ratio, 2.29; 95% CI, 2.15 to 2.44). Of the children who underwent imaging with CT, 2 of 186 children with bleeding disorders had ICH (1.1%; 95% CI, 0.1 to 3.8) , compared with 655 of 14 969 children without bleeding disorders (4.4%; 95% CI, 4.1-4.7; rate ratio, 0.25; 95% CI, 0.06 to 0.98). Both children with bleeding disorders and ICHs had symptoms; none of the children required neurosurgery.
Conclusion:
In children with head trauma, CTs are obtained twice as often in children with bleeding disorders, although ICHs occurred in only 1.1%, and these patients had symptoms. Routine CT imaging after head trauma may not be required in children without symptoms who have congenital and acquired bleeding disorders.
