Abstract

Introduction: traumatic brain injury is a global public health problem due to its severity and high rates of morbimortality worldwide. Identifying predictors associated with increased mortality and unfavorable functional outcomes after the traumatic brain injury event is crucial for minimizing morbidity and mortality rates. Therefore, this study aims to establish a protocol to investigate the predictors of mortality and functional recovery after severe traumatic brain injury in Brazil. Methods: The study will include all patients admitted for severe traumatic brain injury (Glasgow Coma Scale ≤ 8) at the State Hospital of Urgency and Emergency, which is the referral trauma hospital of Espirito Santo. The outcomes of interest are hospital mortality and functional recovery 24 months after hospital discharge. Subjects will be followed up at seventy-two hours, three months, six months, twelve months, and twenty-four months after the trauma. Morbidity will be determined by assessing: 1) the level of motor and cognitive disability, 2) functional impairment and quality of life, and 3) aspects of rehabilitation treatment. Additionally, the traumatic brain injury load, estimated by the years of life lost, will be calculated. Discussion: the results of this study will help identify variables that can predict morbidity and mortality, as well as diagnostic and therapeutic targets for patients with severe traumatic brain injury. Furthermore, the findings will have practical implications for: 1) the development of public policies, 2) investments in hospital infrastructure 3) understanding the socioeconomic impact of functional loss in the individuals. Study registration: the study received approval from the Ethics Committee of the Federal University of Espirito Santo under protocol number 4.222.002 on August 18, 2020.
