Introduction: Brain tumors have an increasing mortality rate; however, the national epidemiological situation remains unknown. Objective: To determine the hospital discharge rate for malignant brain tumors during the period 2019-2022 in Chile. Methodology: Descriptive observational study based on data from the Department of Statistics and Health Information from the Chilean Ministry of Health on Hospital discharges due to malignant brain tumors. Results: The average hospital discharge rate was determined to be 7,88 cases per 100.000 inhabitants, with a male predominance and patients aged 65 to 79 years. The most frequent location was "Malignant Brain Tumor, Except for Lobes and Ventricles." The average hospital stay was estimated to be 13,3 days (DE 0,8 days), with longer stays for "Malignant Brain Stem Tumors." Discussion: Local discharge rate is similar to the global incidence. The predominance in males could be attributed to secondary tumors, mainly of pulmonary origin, as lung cancer has higher incidence than primary tumors. The predominance in extreme age populations could be due to a higher risk of complications and recurrence, as well as prolonged exposure to carcinogens. The average hospital stay in Chile is longer than in other countries, and the length of stay by tumor location may be related to the complexity of surgical interventions. Conclusion: The study highlighted variations in hospitalizations for malignant brain tumors, emphasizing the importance of continuous medical training and specialist review of diagnoses. It is recommended to improve record-keeping, adopt international protocols, and implement ERAS to optimize care and reduce costs.
