Mild traumatic brain injury epidemiology
see Mild traumatic brain injury epidemiology in USA.
The incidence worldwide is approximately 600/100,000 pop. per year, with the incidence requiring hospitalization in the range of 100 to 300/100,000 pop. per year.
It occurs in men twice as often as in the female population, with the age group at highest risk being those aged 15-24 years.
The main causes of MBI are traffic accidents and falls 1).
Mild Traumatic brain injury (mTBI) is a signature wound in military personnel, and repetitive mTBI has been linked to age-related neurodegenerative diseases that affect white matter (WM) in the brain 2).
Saudi Arabia
The incidence of traumatic brain injury (TBI) in Saudi Arabia has been estimated to be 116 per 1,00,000 population as the incidence of TBI continues to rise. Al-Shareef et al. aimed to study the demographics, mortality predictors, and factors influencing the outcome of TBI cases in a tertiary care center in Jeddah, Saudi Arabia. They retrospectively collected data from all consecutive patients treated at the Emergency Department of King Abdulaziz Medical City including all acute TBI adult cases (>18 years) from 2016 to 2019. Logistic regression models were used to identify significant predictors of mortality. A total of 423 individuals with TBI were enrolled in the study. Nearly, half of them were in age group of 18 to 29 (40.77). Most patients were males (76.83%). Results Injuries were most commonly mild traumatic brain injury -to-moderate TBI (73.83%). A road traffic accident was the most common mechanism of injury (49.7%) followed by fall (39.5%). The most common mode of transportation was private cars (47.57%). Most patient required less than or equal to24hours of admission (61.23%). A total of 30 (7%) died in the hospital all of which were male with no death cases reported among females. Conclusion In conclusion, this study reports a mortality rate related to TBI that is among the lowest in the region. Injuries were male predominant with more balanced male to female ratio. Patients who were delivered to the hospital via private cars had an improved survival. These finding should be interpreted in the context of retrospective noncontrolled study design, and further future studies are encouraged to consolidate these findings 3).
