Background: Intracranial trauma (IT) is an injury inside of the cranial box resulting from external forces, usually caused by automotive accidents, falls and violence, sometimes leading to permanent damage or death. Objectives: Describe hospital admissions for IT in the metropolitan region of São Paulo (SP), based on ICD-10 morbidity list. Design and settings: Epidemiological, descriptive and retrospective study. Methods: Data provided from the Hospital Morbidity System (SIH-SUS) of the Ministry of Health, from January 2015 to December 2020. Results: There were 65.455 cases of hospitalizations by IT registered in the metropolitan region of SP, which surpassed the cases of the North and Midwest regions. In 2020, there was a 5% reduction in cases compared to 2019. The amount spent represented 10.5% of the total spent in Brazil. Most of the hospitalization patients were male, and the most affected age group was 40- 49 years. The lethality was 11.05% and higher in patients over 80 years-old. Conclusions: It is essential to control IT’s causing factors, since it engenders high costs, and it is a serious problem for the public health and economy, and for the victim’s psychosocial context. The metropolitan region of SP requires special attention, once it shows higher rates of hospitalizations, morbidity, and mortality than any other brazilian state. Despite the social isolation in 2020, there were no significant differences between this year’s records comparing to the other ones.
