Sponsor's own description
This descriptive study aims to describe the Brazilian scenario of patients hospitalized due to COVID-19 and to analyze the impact of COVID-19 on the Brazilian public health system. Data will be extracted from the largest secondary database of the Brazilian public health system, DATASUS ("Departamento de Informática do Sistema Único de Saúde"), responsible for collecting, processing, analyzing and disseminating health information and statistics in the country. The analysis, performed only on patients hospitalized during the hospitalization episode, will also evaluate the impact of vaccination against COVID-19 on the immunocompromised population compared to the general population.
