Traumatic brain injury in Brazil: an epidemiological study and systematic review of the literature

Abstract

Background: Traumatic brain injury (TBI) is a serious public health problem worldwide. Although TBI is common in developing countries, there are few epidemiological studies. Objective: To investigate the sociodemographic and clinical features of patients with TBI at the Hospital João XXIII, a public reference center for trauma in Belo Horizonte, Brazil, and to systematically review the available literature on TBI in Brazil. Methods: Clinical and sociodemographic data were collected from electronic medical records for the entire month of July 2016. The literature on epidemiology of TBI in Brazil was systematically reviewed using MeSH/DeCS descriptors in the PubMed and Lilacs databases. Results: Most patients admitted with TBI were male and under 60 years of age. Mild TBI was the most prevalent form and the most common cause of TBI was falls. A Glasgow Coma Scale score below 12, neuroimaging changes on computer tomography, and presence of any medical conditions were significantly associated with longer hospital stay. Brazilian studies showed that TBI affected mainly men and young adults. In addition, mild TBI was the most common TBI severity reported and the most common causes were motor vehicle accidents and falls. Conclusions: Overall, the profile of TBI in this center reflects the data from other Brazilian studies.

Predictors of In-Hospital Mortality and Years of Life Lost in Patients with Severe Traumatic Brain Injury: A Retrospective Study in the Metropolitan Region of Vitória, Brazil

“…Traumatic brain injury (TBI) is de ned as any incidence of external force to the head resulting in anatomical injury to the skull followed by brain damage (MAGALHÃES et al, 2022). The type of TBI can predict the severity of the event.…”

“…In other countries, such as the USA, the direct medical care cost was estimated to be approximately US$95 million, equivalent to US$1.67 million per 100,000 people. In Europe, traumatic injuries represent 37% of all deaths from traumatic injuries, resulting in a nancial impact of €22,907 million in 2010 (MAGALHÃES et al, 2022). In Brazil, the nancial impact of healthcare costs exceeded US$43,000,000.00, with an average cost per admission of US$327.68 (CARTERI et al, 2020).…”

Arguição Do Perfil Epidemiológico Dos Casos Confirmados Por Traumatismo Cranioencefálico No Brasil De 2014 a 2023

“…Este desequilíbrio no movimento pode causar ruptura das veias cerebrais que drenam para as cavidades durais e impacto e ruptura do parênquima contra as estruturas rígidas do crânio. 1,2,10,11,12,13 As lesões secundárias decorrem de agressões que se iniciam após o momento do acidente, resultantes da interação de fatores intra e extracerebrais, que se somam para inviabilizar a sobrevivência de células encefálicas poupadas pelo trauma inicial. No local do acidente complicações clínicas como hipotensão arterial, hipoglicemia, hipercapnia, hipóxia respiratória, hipóxia anêmica e distúrbios hidroeletrolíticos são os principais fatores de lesões secundárias.…”

“…Acrescentam-se então outros distúrbios metabólicos sistêmicos e infeções, além da presença de substâncias neurotóxicas, hidrocefalia e alterações hemodinâmicas no espaço intracraniano. 1,2,10,11,12,13 Manejo TCE grave.…”

Dosage of Alcohol, Cocaine and Marijuana in Patients with Moderate and Severe Traumatic Brain Trauma Attended at the Hospital of Clinics of the Federal University of Uberlândia

“…Young men are more involved in most statistics, perhaps because they take more risks in traffic and are more likely to use alcohol and illicit drugs. 1 2 TBI is considered a major public health problem worldwide, as it incurs high socioeconomic costs, requiring prolonged hospitalizations and specialized treatments. 3 It is estimated that in Brazil the annual costs of hospitalization for patients suffering from traumatic brain injury are US$ 70,960.0004 or 376,698,256.00 reais (US dollar exchange rate as on 08/07/2022; source: Web site of the Central Bank of Brazil – bcb.gov.br).…”
