Public expenditure on hospitalizations for COVID-19 treatment in 2020, in Brazil.

Hospitalizations for clinical treatment of coronavirus infection were more costly compared to those for treatment of acute respiratory failure and pneumonia or influenza. Our results show the disparities in hospitalization expenditure for similar procedures between the regions of Brazil, underlining the vulnerability and the need for strategies to reduce the differences in access, use, and distribution of SUS resources, ensuring equanimity, and considering the unfair inequalities between the country's regions.
