Emergency Department Evaluation of Young Infants With Head Injury

Area of Science:

• Pediatric Emergency Medicine
• Neurotrauma Research
• Public Health

Background:

• Head injuries in young children require careful evaluation in emergency departments (EDs).
• Infants, particularly those under 3 months, represent a vulnerable population with unique physiological considerations.

Purpose of the Study:

• To compare the emergency department (ED) evaluation and outcomes of young head-injured infants (<3 months) with those of older children (3-24 months).
• To identify disparities in diagnostic imaging utilization, traumatic brain injury (TBI) diagnosis, and mortality rates between these age groups.

Main Methods:

• Retrospective, cross-sectional analysis of the Pediatric Health Information Systems database (2015-2019).
• Inclusion of children under 2 years old with isolated head injuries across 47 EDs.
• Primary outcome: diagnostic cranial imaging. Secondary outcomes: TBI diagnosis, clinically important TBI, and mortality.

Main Results:

• Youngest infants (<3 months) were significantly more likely to undergo cranial imaging (50.3% vs 18.3%) compared to older children (12-23 months).
• Infants <3 months had higher rates of TBI diagnosis (17.5% vs 2.7%), clinically important TBI (4.6% vs 0.5%), and mortality (0.3% vs 0.1%).
• Among those with imaging, TBI was more common in the youngest infants (26.4% vs 8.8%).

Conclusions:

• Young infants with head injuries exhibit significantly higher rates of cranial imaging, TBI diagnosis, and mortality.
• These findings underscore the critical need for specialized evaluation and management protocols for head-injured infants.
• Further research into age-specific risk factors and optimal diagnostic strategies is warranted.
