Perfil epidemiológico dos internamentos por traumatismo cranioencefálico no Brasil (2010 – 2019).

Abstract

Head trauma is characterized as an injury to the brain parenchyma, which can lead to permanent or temporary impairment of cognitive, physical and psychosocial functions. Thus, it is possible to characterize traumatic brain injury as a public health problem. Objective: To analyze the epidemiological profile of admissions for traumatic brain injury due to external causes in Brazil, from 2010 to 2019. Method: Ecological time series study, with data from the Hospitalar Information System. A descriptive analysis of the data was performed using absolute, relative and accumulated frequencies associated with measures of central tendency, mainly the mean, and dispersion measures, highlighting the standard deviation. In the inferential analysis, time trend data were processed using simple linear regression. Results: Among the years investigated, 1,045,092 hospitalizations for traumatic brain injury were registered, predominantly in the Southeast and Northeast regions. The cases stood out in young adults, caucasians and browns (62%) and males (76.2%). The highest rates of admissions occurred between the years 2014 and 2016, and the average hospital stay was 6.2 days in general. The national hospital mortality rate was 9.49 deaths per 100 admissions. Conclusion: The study allowed us to confirm the epidemiological profile of hospitalizations for traumatic brain injury diagnosed in Brazil, elucidating sociodemographic characteristics of the notified cases at the regional level.
