Abstract

Traumatic brain injury is a major cause of death and disability worldwide, with almost half of new cases occurring in children, adolescents, and young adults. However, data on injury characteristics stratified by social determinants of health are scarce.

Introduction

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide (1). In 2016, there were over 27 million new cases of TBI globally, with approximately 47% of new cases occurring in those <30 years of age [1]. A population-based birth cohort of individuals born in Ontario, Canada found that 36% of individuals in this cohort sustained a TBI that required medical attention by the age of 25 years.

Methods

Research ethics approval was obtained from the University Health Network. Informed consent was not obtained because only de-identified patient data was accessed for this study on July 30, 2021.

Results

Over 90% of index TBI-related healthcare visits to the ED or acute care occurred before the age of 20 years. The majority (56.4%) of visits were among males and those living in an urban neighbourhood (81.6%) at the time of TBI.

Discussion

This population-based birth cohort study explored the injury characteristics for individuals who experienced a TBI-related healthcare visit to the ED or hospital. Findings from this study identified opportunities for targeted prevention of TBI and early intervention for TBI care across SDoH. In particular, current prevention and education measures are often focused on sport-related injuries [30] and may not be applicable to the general population.

Conclusions

This population-based birth cohort study addressed existing gaps in knowledge and research on TBI to provide foundational data to inform the co-creation of targeted prevention of TBI at the community-level. Findings showed a minority of females, children younger than age 10 years.
