A Novel Approach to Assessing Head Injury Severity in Pediatric Patient Falls

Area of Science:

• Biomedical Engineering
• Pediatric Safety
• Injury Biomechanics

Background:

• Pediatric patient falls, especially those with head-to-floor impact, pose a significant risk for injury.
• Objective measurement of head injury severity is crucial for accurate assessment and management.

Purpose of the Study:

• To calculate the Head Injury Criterion (HIC₁₅) for pediatric falls using anthropometric and biomechanical data.
• To compare HIC₁₅ values with the hospital's subjective harm level assignments.

Main Methods:

• Utilized adverse event reports from 49 pediatric falls (ages 11 months to 17 years).
• Calculated HIC₁₅ based on fall height, contact velocity, and acceleration.
• Correlated HIC₁₅ levels with hospital-assigned harm levels (1-9 scale).

Main Results:

• HIC₁₅ levels ranged from 26.4 to 1,330.0.
• Seven (14.3%) children exceeded age-specific HIC₁₅ thresholds, with no follow-up indicated.
• Hospital-assigned harm levels showed no significant correlation with HIC₁₅ (r = .23, p = .12).

Conclusions:

• Objective HIC₁₅ assessment is vital for pediatric fall injuries.
• Current subjective harm level assignments do not accurately reflect objective injury severity.
• A point-of-care HIC₁₅ algorithm could improve diagnostic and follow-up decisions for pediatric head injuries.
