Objective To analyze the temporal trend of TBI incidence in Brazil between 2008 and 2019, according to age group and gender. Methods An ecological study, based on secondary data from hospital admissions for TBI in all Brazilian states between 2008 and 2019. The numbers were collected using the hospital information system of the Unified Health System in Brazil. We performed a descriptive analysis using the data obtained. Linear regression models were used to measure the incidence trend of TBI in the period adopted. Results The state of Piauí had the highest increase in the incidence of TBI in the country in the last 10 years (coefficient β ¼ 63.43 e p ¼ 0.002). The main concern, though, is the increase in the incidence of TBI amongst children (0–4yearsold)inthe states of Ceará (β ¼ 31.22 and p < 0.001 for boys; β ¼ 42.20 and p < 0.001 for girls), Paraná (β ¼ 37.26 and p ¼ 0.011 for boys; β ¼ 25.90 and p ¼ 0.015 for girls), Pernam- buco (β ¼ 20.08 and p ¼ 0.016 for girls), Mato Grosso (β ¼ 18.76 and p ¼ 0.005 for boys; Keywords β ¼ 16.11 and p ¼ 0.035 for girls), and Distrito Federal (β ¼ 48.87 and p ¼ 0.004 for ► traumatic brain injury girls; β ¼ 48.28 and p ¼ 0.006 for boys). ► trauma Conclusion The analysis of the results is able to point out improvements that can be ► incidence made.

Resumo Introdução O traumatismo cranioencefálico (TCE) é um problema de saúde pública com alto impacto econômico, além de uma importante causa de morte e sequela em pacientes politraumatizados, afetando principalmente adultos jovens. Objetivo Analisar a tendência temporal da incidência de TCE no Brasil entre 2008 e 2019, segundo faixa etária e sexo. Método Estudo ecológico, baseado em dados secundários de internações hospita- lares por TCE em todos os estados brasileiros entre 2008 e 2019. Os números foram coletados por meio do sistema de informações hospitalares do Sistema Único de Saúde do Brasil. Realizamos uma análise descritiva a partir dos dados obtidos. Modelos de regressão linear foram utilizados para medir a tendência da incidência de TCE no período adotado. Resultados O estado do Piauí apresentou o maior aumento na incidência de TCE no país nos últimos dez anos (coeficiente β ¼ 63,43 e p ¼ 0,002). A principal preocupação, porém, é o aumento da incidência de TCE entre crianças (0-4 anos) nos estados do Ceará (β ¼ 31,22 e p < 0,001 para meninos; β ¼ 42,20 e p < 0,001 para meninas), Paraná (β ¼ 37,26 e p ¼ 0,011 para meninos; β ¼ 25,90 e p ¼ 0,015 para meninas), Palavras-chave Pernambuco (β ¼ 20,08 e p ¼ 0,016 para meninas), Mato Grosso (β ¼ 18,76 e p ¼ 0,005 ► traumatismo para meninos; β ¼ 16,11 e p ¼ 0,035 para meninas) e Distrito Federal (β ¼ 48,87 e cranioencefálico p ¼ 0,004 para meninas; β ¼ 48,28 e p ¼ 0,006 para meninos). ► trauma Conclusão A análise dos resultados é capaz de apontar melhorias que podem ser ► incidência feitas. Além disso, é extremamente importante redirecionar as políticas públicas para a ► epidemiologia medicina preventiva, uma vez que muitas das causas doTCE são evitáveis por meio da ► Brasil conscientização e educação da população. 1 1,2 Introduction scalp, occurring due to physical impact.

Methods The North Region (Acre, Amapá, Amazonas, Pará, Rondônia, Roraima, Tocantins) This ecological study was conducted based on secondary data In Acre, there was a statistically significant reduction in the from hospital admissions for TBI in all Brazilian states between incidence of hospital admissions for both female and male 2008 and 2019. Data was collected from the Department of patients (β coefficient: -2.09 e -0.86, respectively). The Informatics of the Unified Health System (DATASUS). The largest reduction was observed in men in the 30 to 40 years Department of Informatics of the Unified Health System is old age group (β coefficient: -51.15). the official database of the Brazilian Health Ministryandcan be In Amazonas, the total incidence of admissions increased visited for free on the website www.datasus.gov.br. in the female gender (β coefficient: 0.66), mainly in the age We searched DATASUS for the number of hospital admis- extremes (0–4and 75 years old). In the male gender, the sions between 2008 and 2019, including female/male global increase of the incidence of TBI in 2.5 times (β patients in different age groups, from 0 to 80 years old, all coefficient: 2.53) was a result of the higher number of cases identified by the ICD 10-S09.
