TBI IN FIGURES
In Spain, there are around 200 cases of TBI per 100,000 population. Approximately 10% are serious, 10% are moderate, and 80% are mild.
TBI is three times more common in men than in women, and the most commonly affected age group is 15–35 year olds.
In Spain, road traffic accidents are the most common causes of TBI, causing around 75% of instances of TBI. The second most common cause of TBI is falls (20%), and sporting injuries cause the remaining 5% of cases. There are age and gender differences in the number of cases of TBI. Accidents and falls are more common in children and in adults aged 65 or over, whereas motorcycle accidents mostly affect people aged 25 or under, and car accidents mostly affect adults.
Around one in five survivors of TBI develops a moderate or severe disability.
Overall, mortality from TBI occurs in 11% of cases, and the annual mortality rate per 100,000 population is 15. TBI is the principal cause of death or disability in individuals younger than 45 years old.
Severe TBI is particularly relevant because of the high rate of mortality and sequelae. Nevertheless, mild and moderate cases of TBI represent a challenge for emergency services. This pathology has a high incidence, and establishing the severity of the TBI is paramount because of the potential risk of complications or an unfavourable clinical course in the hours directly following the TBI.
