Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
