The economic impact of stroke in Brazil, 2010-2019: Increase in public expenses of Unified Health System

Abstract

Objectives: To economically analyze the impact that outpatient and inpatient spending of the Unified Health System and social security expenses of the General Regime of Social Security generated to the Brazilian public system, between 2010 and 2019.

Materials and methods: Observational research, in which public data from the SUS Department of Informatics and the Social Security Historical Database were used, according to 10ª International Classification of Diseases code, I-64 (Stroke, not specified if hemorrhagic or ischemic). The Kruskal-Wallis test, complemented by Dunn's post-hoc test, and Spearman's bivariate correlation test were used to check for differences and correlations between variables. The expenditures were adjusted for inflation for the year 2019 and presented in american dollar s(U$).

Results: Stroke public spending impacted an average of 120 million dollars per year and increased 15% during the historical series. Eighty-nine percent of these expenditures originated from hospital spending (p<0.05). On average, stroke accounted for 7.3% of spending on cardiovascular diseases and 0.72% of spending on the other codes of 10ª International Classification of Diseases. Total spending showed a positive correlation with the historical series (r=.702; p<0.05), with the increase in the elderly population (over 60 years of age) (r=.676; p<0.05) and with Gross Domestic Product per capita (r=.784; p<0,05).

Conclusions: The impact that stroke generated on public spending increased over the historical series, mainly due to hospital spending and by the prospect of increasing elderly population in Brazil, public spending tends to rise.
