Morbidity and Mortality of Traumatic Brain Injury in Hospitalized Patients in Brazil Between 2010 and 2020: An Ecological Study

Background: Traumatic Brain Injury (TBI) is defined as any traumatic injury causing an anatomical lesion or functional impairment of the scalp, skull, meninges, brain or its vessels. Hospitalization of this patient, depending on the severity, can result in irreversible sequelae or death. Objective: To report the morbidity and mortality rates of patients suffering from TBI hospitalized in Brazilian hospitals between 2010 and 2020. Methods: Descriptive ecological study of the data collected at the Informatics Department of the Unified Health System (DATASUS). Results: There were 1,143,187 admissions due to TBI. There was a predominance of males with 871,999 (76.28%) cases and the age group between 20 and 29 years old 199,857 (17.48%). Brown patients were the ones with the highest hospitalization rate: 370,639 (32.42%). The mortality rate in the period was 9.52/100 hospitalizations, with the Southeast region occupying the first place (10.44 per 100 hospitalizations). In total, 108,853 deaths were recorded, of which 50,013 occurred in the Southeast, the region with the highest rate. Although the number of deaths was higher in people between 20 and 29 years old (16,687), the age group with the highest mortality rate was over 80 years old (19.84 per 100 hospitalizations). Conclusion: In the last 10 years, TBI has caused 1,143,187 hospitalizations in Brazil, with a predominance of males and the age group between 20 and 29 years. Brown patients had the highest rate of hospitalization. The region with the highest mortality was the Southeast and the smallest was the South.
