Introduction: Traumatic brain injury (TBI) is a global problem and the biggest cause of mortality and disability of all trauma cases. This study aimed to determine the characteristics and relationship between risk factors for TBI and its impact on mortality and also to provide epidemiological data related to TBI in Belitung regency. Methods: A retrospective study was conducted using secondary data from the medical records of participants who met the inclusion and exclusion criteria at dr. H. Marsidi Judono General Hospital Belitung from January to December 2019. Data were analyzed as univariate, bivariate, and multivariate using binary logistic regression. Results: Two hundred and seventy patients were included in this study. Men were more likely to have a TBI than women in all categories (65.9%). The adolescent age group (33.7%) followed by adults (31.5%) were the largest contributors to TBI. Road traffic accident cases (86.7%) dominated the incidence of TBI. The use of headgear was still lacking (36.7%) while cases of road traffic accidents were high. The use of ambulances was lacking (10.4%) compared to other vehicles. A total of 119 patients (44%) were hospitalized in either the general ward or ICU with an average length of hospitalization was 3 days. Of all TBI cases, the mortality rate was 11.9%. People with older age have a higher mortality rate compared to other age categories (OR 1.052; 95% CI: 1.001 – 1.106). Conclusion: The mortality rate due to TBI reaches 11.9% in this region, with age as a statistically significant predictor of mortality due to TBI. Older patients tend to have a higher likelihood of death due to TBI.
