Background: Thoracic trauma is defined as a trauma that hits the chest wall directly or indirectly, either as a result of blunt or penetrating trauma. Thoracic trauma can occurred in any age or genders, and become a life-threatening if the treatment isn’t immediate and  appropriate. Methods: This research was an observational study with a cohort retrospective design using secondary data in the form of thoracic trauma patients at The Zainoel Abidin General Hospital, Banda Aceh, Indonesia in the period January 2019- December 2020. The statistical analysis used were chi square for bivariate and  multivariate analysis, spesifically logistic regression analysis was conducted to know which risk factor influences the most. Result:  There were 141 medical records used in this study, thoracic trauma was more common in men compared to women. The age group of 46-55 is the age group with the highest percentage of thoracic trauma patients, road traffic are the leading cause of thoracic trauma where the most common diagnosis is rib fractures. Significant factors that associated with the short outcome of thoracic trauma are thoracic trauma diagnosis (p=0,00), management of thoracic trauma (p=0,00), ventilator (p=0,04), duration of ventilator (p=0.01), sepsis (p=0,00), qSOFA score (p=0,00) and  injury severity score (p=0,00). Conclusions: Motorbike accidents contributed to a considerable number of traumatic chest injuries in this study. Diagnosis, management of trauma, days of ventilation, qSOFA score, injury severity score, and development of sepsis were associated with the short-term outcome among thoracic trauma patients.  Injury severity score seems to be the most influential variable in this study, the lower the better it is. Road safety intervention is urgently needed to control the underlying problems in this study.
