Custo das Internações por Acidente Vascular Cerebral no estado do Mato Grosso do Sul no período de 2014 a 2024.

Abstract

Introduction: Stroke is one of the leading causes of mortality and disability, imposing a significant financial burden on the Unified Health System. In Mato Grosso do Sul, a detailed understanding of the costs and patient profile is essential for health policy planning. Methodology: A cross-sectional study of partial economic evaluation from the perspective of the SUS, with macro-cost analysis for stroke hospitalizations in MS from 2014 to 2024. With secondary data from the SIH in DATASUS's reduced AIH. TabWin was used for collection and extraction. The coded variables were processed in VBScript and statistically analyzed in Jamovi. Results: The database totaled 28,384 records, with total costs (SUS billing) of R$ 68,936,294.49. There was an upward trend in the number of cases (2,127 in 2014 to 3,152 in 2024) and costs. The overall average cost per hospitalization was R$ 2,428.70. The most frequent diagnostic categories were unspecified stroke (72.9%), hemorrhagic stroke (18.0%), and ischemic stroke (9.1%). Stroke predominantly affected the elderly (average age 64.2 years). Spearman's correlation showed positive associations between total cost and total days in the ICU (ρ = 0.730; p < 0.001) and moderate associations with patient length of stay (ρ = 0.576; p < 0.001). The multiple linear regression model (R²=0.81) identified the total number of days in the ICU (β = R$ 600.60 per day), admission to the Surgical Clinic (β = R$ 4,480.40), use of the ICU (β = R$ 383.80), and length of stay (β = R$ 57.50 per day). Conclusion: The analysis points to a scenario of continuous increase in stroke cases and associated costs. The expenditure profile is strongly influenced by the need for intensive care, complex interventions, and length of stay, which emerged as the main predictors in the regression model. The high frequency of unspecified diagnoses limits epidemiological analysis by stroke subtype. The billing values found suggest potential underfunding when compared to actual cost studies, reinforcing the importance of strengthening prevention policies to contain the financial and social burden of the disease in the state. Further studies are recommended to assess the impact of specific lines of care on resource optimization and outcome improvement.
