Impacto da estrutura etária nos custos hospitalares das doenças cerebrovasculares

Abstract

Characterize the clinical-epidemiological profile and analyze the temporal trend of hospitalizations for cerebrovascular diseases (CVD), as well as SUS reimbursement values for hospital care provided at a public hospital in Uberlândia-MG, Brazil, from 2014 to 2024.Methods:Retrospective observational study using SIH/SUS time series data, comprising 3,519 CVD hospitalizations (ICD-10 I60-I64, I67.3-9, I69.0-4,8). Demographic (gender, race, age), care-related (length of stay, ICU admission, mortality), and financial (SUS reimbursement) variables were stratified by etiological subtype and age group. Analyses included Mann-Kendall and Dickey-Fuller trend tests, Mann-Whitney and chi-square independence tests, performed in Python 3.14.Results:Older adults (≥60 years) accounted for 57.9% (n=2,038) of cases, predominating in DCBVNE (67.4%) and DCBVI (63.6%). Hemorrhagic CVD (DCBVH) exhibited greatest severity: mortality 24.9% (n=357), mean length of stay 14.74 days, ICU stay 6.03 days. Temporal trends were more pronounced among elderly (τ=0.6456; p<0.001) versus adults (τ=0.4863; p<0.001). SUS reimbursements increased 150% (R$85.9 million to R$215.8 million), concentrated in elderly patients (R$798.6 million; 47.4%) and DCBVH (R$1.11 billion; 66.1%).Conclusion:Population aging drives exponential increases in CVD hospitalizations and SUS costs, particularly for severe hemorrhagic events, necessitating preventive care planning and targeted public health policies.
