Official Title
Covid-19 Data Analyses in Brazil. Retrospective Study Using an Open Data Plataform (DataSUS) to Describe and Analyze Patient Characteristics and Covid-19 Outcomes in Brazil.
Brief Summary

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

Detailed Description

This is an observational, retrospective, descriptive study based on a secondary database
from the Brazilian public health system. Data were collected from three public databases
in a large system (DATASUS). These databases are SRAG ("Síndrome Respiratória Acuta"),
SIH ("Sistema de Informação Hospitalar"). All data collected are de-identified, which
does not allow the identification of sensitive data of participants. The population of
this study would be representative of a significant sample of individuals present in the
health records system registered with COVID-19. The data included in this study were
acquired between January 2021 and December 2023. This analysis will not include data from
specific vaccine brands. The data described refer only to the episode of hospitalization
related to COVID-19. The primary objective is to describe the demographic and clinical
characteristics of individuals hospitalized for COVID-19 between January 2021 and
December 2023, stratified by underlying CI, number of vaccine doses received, age, and
period of the predominant variant.

As a secondary objective, it is to describe in-hospital mortality due to COVID-19 among
individuals hospitalized for COVID-19 between January 2021 and December 2023, stratified
by underlying CI, number of non-CI comorbidities, number of vaccine doses received, age,
and period of the predominant variant. And also as an exploratory objective, it is
expected to describe the use of hospital healthcare resources (HCRU) and the costs
associated with hospitalizations related to COVID-19 between January 2021 and December
2023.
