Abstract WP288: Epidemiological Analysis of Incidence, Treatment, Mortality and Costs of Cerebrovascular Diseases in Brazil Between 2017 and 2022

Abstract

Background: Cerebrovascular diseases (CVD) represent a Global Health concern, being the first cause of disability worldwide and second cause of mortality (first in Brazil). Despite that, detailed data from Brazil was scarce and this study found alarming results. Aims: The study aims to analyze incidence, mortality, treatment, procedures and costs related to the three most common cerebrovascular diseases: Subarachnoid Hemorrhage (SAH), Intracerebral Hemorrhage (ICH) and Ischemic Stroke in Brazil. Methods: This is an epidemiological study. Data was obtained through DataSUS, a public database. For the search, we utilized the CID-10 notification system from I60 until I64, including admissions, deaths, treatments and costs related to each CID-10. Results: Between 2017 and 2022, 1,283,435 CVD cases were notified (SAH=4,7%; ICH= 8.8%; and ischemic stroke=86.5%). 52.4% were Male and 47.6% were Female. Mortality percentages were: SAH=20.2%, ICH=25.3%, Ischemic Stroke=15.3%. Rates of Thrombolysis were alarming, but with an increasing tendency: 22969 were performed, from 1.6% in 2017 to 2.3% in 2022 of all ischemic strokes. 8290 aneurysms embolizations were performed (13.5% of all SAH cases). 4.9% of SAH cases were treated with neurosurgical clipping, demonstrating a decrease tendency after 2020, as well other procedures, such as Craniectomy and Angioplastia. Yearly costs related to these diseases increased steeply, from R$ 360,710,749.92 in 2017 to R$ 537,511,793.62 in 2022 (around US$107,502,358.00). Conclusions: This study has found increasing incidence and costs associated with low rates of thrombolysis and procedures in Brazil The results can direct Public Health policies in developing countries, and similar research in other low- and middle-income-countries are encouraged.
