BACKGROUND/AIMS: Mild traumatic brain injury (mTBI) in young children is a growing public health concern. This study aimed to document the epidemiology of injury circumstances, mechanisms and products implicated in unintentional mTBI among children aged 0-5 years presenting to Canadian emergency departments.
METHODS: A retrospective observational study was conducted using data from the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) for all children aged 0-5 years old who experienced mTBI from 2012 to 2022.
RESULTS: A total of 79 345 unintentional mTBI cases were recorded in CHIRPP across the study period. The most frequent mechanisms of injury were falls (n=67 599, 85.2%), being struck by/against an object (n=10 240, 12.9%) and transport-related injuries (n=1478, 1.9%). The prevalence of falls was 21% higher in infants (<1 year, prevalence risk ratios (PRR)=1.21, 95% CI=1.19 to 1.23, p<0.001) and 17% higher in toddlers (1-2 years, PRR=1.17, 1.15-1.19, p<0.001) compared with preschoolers (3-5 years). Children primarily fell from beds (n=11 208, 16.6%). Falls from beds were 3.49 (PRR=3.49, 95% CI=3.29 to 3.72, p<0.001) times more common in infants and 1.34 (PRR=1.34, 95% CI=1.25 to 1.44, p<0.001) times more common in toddlers versus preschoolers. Floors were the main surface fallen onto (n=35 577, 52.6%).
CONCLUSIONS: This is the first large-scale study on injury circumstances among young children who sustain mTBI in Canada. These findings are critical to inform mTBI prevention initiatives.
