Temporal trend of hospitalization for chronic venous disease in Brazil from 2014 to 2023.

Abstract

Background: Chronic Venous Disease (CVD) of the lower extremities (LEs) is a condition with significant prevalence and hospital admission rates.

Objectives: To analyze temporal trends in hospitalization due to CVD from 2014 to 2023 in Brazil.

Methods: An ecological time series study of CVD-related hospitalization using data from the Brazilian Unified Health System. Data were analyzed using simple linear regression with annual variation (β) and percentage changes, with significance set at p < 0.05.

Results: A total of 1,091,733 CVD-related hospital admissions were recorded for the period assessed. The overall rate showed a stable trend (β = -3.233; p = 0.060), with an average of 73.98 hospital admissions per 100,000 inhabitants. Statistically significant reductions were observed in the Northeast (β = -1.275; p = 0.042), Southeast (β = -4.262; p = 0.044), and South (β = -7.282; p = 0.012) regions of Brazil. The North and Midwest regions had stable rates. Both sexes showed stable trends, although hospital admission rates were higher among women. Significant reductions were found among men aged 20 and older and among women aged 20 - 49 and 70 and older. Stable rates were observed in women aged 50-69.

Conclusions: Overall hospital admission rates for CVD in Brazil remained stable between 2014 and 2023. However, regional and age-specific differences highlight the need for targeted public health strategies, particularly for women aged 50-69 and residents of the North and Midwest regions.
