Objective:

To estimate the incidence rates (IR) of paediatric traumatic brain injury (TBI) in Denmark using national health registry data, providing updated epidemiological insights for targeted prevention efforts and clinical management.

Key Findings:
  • The incidence rates of paediatric TBI varied significantly over the study period, with a notable increase in reported cases.
  • Falls were identified as the most common cause of TBI in children, consistent with global patterns.
  • The study highlights the importance of accurate reporting and the potential underestimation of mild TBI cases, which may affect overall incidence rates.
Interpretation:

The findings underscore the need for enhanced surveillance and prevention strategies for paediatric TBI, particularly in light of the increasing incidence rates observed, which could inform public health initiatives.

Limitations:
  • The study may not capture all mild TBI cases due to underreporting of non-hospitalized injuries, potentially skewing incidence rates.
  • Variability in TBI severity classification could lead to misclassification in some cases.
Conclusion:

This study provides critical insights into the incidence of paediatric TBI in Denmark, emphasizing the necessity for targeted prevention initiatives and resource allocation in healthcare to address this growing concern.
