Prevalence of traumatic brain injury amongst children admitted to hospital in one health district: a population-based study.

There is a dearth of information regarding the prevalence of brain injury, serious enough to require hospital admission, amongst children in UK. In North Staffordshire, a register of all children admitted with traumatic brain injury (TBI) has been maintained since 1992 presenting an opportunity to investigate the incidence of TBI within the region in terms of age, cause of injury, injury severity and social deprivation. The register contains details of 1553 children with TBI, two-thirds of whom are male. This population-based study shows that TBI is most prevalent amongst children from families living in more deprived areas, however, social deprivation was not related to the cause of injury. Each year, 280 per 100,000 children are admitted for >or=24h with a TBI, of these 232 will have a mild brain injury, 25 moderate, 17 severe, and 2 will die. The incidence of moderate and severe injuries is higher than previous estimates. Children under 2 years of age account for 18.5% of all TBIs, usually due to falls, being dropped or non-accidental injuries (NAIs). Falls account for 60% of TBIs in the under 5 years. In the 10-15 age group road traffic accidents (RTAs) were the most common cause (185, 36.7%). These findings will help to plan health services and target accident prevention initiatives more accurately.
