ABSTRACT
Traumatic subdural hemorrhage (TSH) is an injury between the meningeal membranes, caused by traumas, especially traffic accidents. OBJECTIVE: To describe the mortality rate (MR) due to TSH in the period 2018-2022 in Chile. MATERIALS AND METHODS: Descriptive, observational, and cross-sectional study on MR due to TSH in the period 2018-2022 in Chile, according to gender, age group, regional distribution, place of death, and month of death. Anonymous and public databases were used. No ethics committee approval was required. RESULTS: The average MR due to TSH in Chile from 2018 to 2022 was 0.45/100,000 inhabitants, with a peak in 2018 (0.75) and a minimum in 2021 (0.31). Men had higher rates. Mortality increased with age, especially in those over 80 years. The Metropolitan Region accounted for 35.2% of TSH-related deaths. Hospitals and clinics were the main places of death (67.1%), with more deaths in March, July, and August. DISCUSSION: The MR due to TSH progressively decreased due to medical improvements. Men have higher rates, possibly due to risk factors or biological differences. The reduction in MR in hospitals is linked to changes in the severity and categorization of the place of death. The connection with traffic accidents is significant, especially between March and August, due to the return to academic activities and weather conditions. Additionally, TSH-related deaths are concentrated in densely populated regions with more traffic accidents.

Introducción: La hemorragia subdural aguda no traumática (HSDNT) es una patología relacionada a factores de riesgo cardiovascular (RCV). Por falta de estudios epidemiológicos nacionales, se plantea estudiar la tasa de mortalidad (TM) y defunciones por HSDNT entre los años 2017-2021 en Chile. Metodología: Estudio descriptivo, transversal, sobre defunciones por HSDNT entre los años 2017-2021 en Chile (N=878), según grupo etario, sexo y lugar de defunción, usando datos obtenidos del departamento de estadística e información en salud. Se utilizó estadística descriptiva y cálculo de TM. No requirió aprobación por comité de ética. Resultados: Se calculó una TM de 0,99/100.000 habitantes entre los años 2017-2021, siendo la mayor los años 2017-2019 y 2020 con TM de 1/100.000. El sexo masculino presentó TM de 1,27/100.000, el grupo etario mayor a 80 años presentó una TM de 19,28/100.000 habitantes. Según lugar de defunción, el año 2020 un 83% (148) de las defunciones fue en hospital o clínica. Discusión: La prevalencia del RCV hace relevante el estudio de mortalidad por HSDNT, donde la principal hipótesis de su mortalidad en Chile estaría basada en estos factores riesgo latentes. Según lugar de defunción, se podría suponer dadas mayores complicaciones en aquellos pacientes hospitalizados por HSDNT. Conclusión: Dada la nula existencia de datos sobre esta patología en Chile, se realizó una caracterización epidemiológica en conjunto a un análisis de defunciones según el lugar, aportando una perspectiva nacional de mortalidad sobre este cuadro en particular.
Introduction: Non-traumatic acute subdural hemorrhage (NTSDH) is related to cardiovascular risk factors (CVR). Due to lack of national epidemiological studies, it is proposed to study mortality rate (MR) and deaths from HSD between the years 2017-2021 in Chile. Methodology: Descriptive, observational, cross-sectional study on deaths due to SDH between the years 2017-2021 in Chile (N=878), in a population older than 15 years, according to age group, sex and place of death, using data obtained from Departamento de estadísticas e información en salud. Descriptive statistics and MR calculation were used. It did not require approval by an ethics committee. Results: A MR of 0.99/100,000 inhabitants was calculated between the years 2017-2021, the year being the highest in the years 2017-2019 and 2020 with MR of 1/100,000. Male sex presented a MR of 1.27/100,000, the age group over 80 years presented a MR of 19.28/100,000 inhabitants. By place of death, in 2020 there were 148 deaths in hospitals or clinics. Discussion: The prevalence of CVR makes the study of mortality from NTSDH relevant, where the hypothesis of its mortality in Chile would be based on these risk factors. Depending on the place of death, it could be assumed that there are greater complications in those patients hospitalized for NTSDH. Conclusion: Given the null existence of data on this pathology in Chile, an epidemiological characterization was carried out together with an analysis of deaths according to the place, providing a national perspective of mortality about this disease.
