<![CDATA[Background: Road traffic accidents remain a significant global health problem and are among the leading causes of trauma-related mortality, particularly in developing countries. Head injury is one of the most serious consequences of road traffic accidents and contributes substantially to death and disability. Several factors, including age, sex, and type of intracranial haemorrhage, have been reported to affect mortality among patients with head injuries; however, studies in Indonesia have generally examined these factors separately. Evidence regarding the simultaneous relationship of these variables with mortality remains limited. Therefore, this study aimed to analyze the relationship between age, sex, and type of haemorrhage and mortality in patients with head injuries following road traffic accidents. Subjects and Method: This cross-sectional study included 1,355 patients with head injuries due to road traffic accidents treated at Rumah Sakit Umum Daerah dr. Moewardi, Surakarta. Data on mortality, age, sex, and type of hemorrhage were collected from medical records (January 2023–January 2026) and analyzed using multiple logistic regression. Results: Older adults had a significantly higher risk of mortality than adults (OR= 2.03; 95% CI= 1.66 to 2.47; p<0.05). No significant association was found between sex and mortality (p>0.05). Mortality was significantly associated with the type of hemorrhage (p<0.05), with subdural hemorrhage showing the highest mortality rate (26.5%). Multivariate analysis demonstrated that age (aOR= 2.34; 95% CI= 1.77 to 3.08; p<0.05) and type of hemorrhage (aOR= 1.44; 95% CI= 1.22 to 1.71; p<0.05) were independent predictors of mortality, with age contributing more strongly to the model. Conclusion: Advanced age and subdural haemorrhage significantly associated with increased mortality in patients with head injuries following road traffic accidents, whilst gender was not found to be a significant factor.]]>
