This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Objective:
To describe in-hospital and intensive care unit (ICU) case fatality rates due to COVID-19 in four Brazilian state capitals, during the months of epidemic peaks and previous months.Methods:
This was an ecological study using monthly data from the Influenza Epidemiological Surveillance Information System, between 2020-2021, in individuals aged 20 years or older. Case fatality rate and mortality were estimated with 95% confidence intervals.Results:
In Manaus, the capital city of the state of Amazonas, ICU case fatality rate among those >59 years old was lower in December/2020 (80.9% 95%CI 78.4;83.3) and during the peak in January/2021 (79.9% 95%CI 77.4;82.5), compared to the peak in April/2020 (88.2% 95%CI 86.1;90.3). In São Paulo, the capital city of the state of São Paulo, Curitiba, the capital city of the state of Paraná, and Porto Alegre, the capital city of the state of Rio Grande do Sul, there was a decrease or stability in ICU and in-hospital case fatality rate in January/2021, compared to the reference month in 2020.Conclusion:
In January/2021, in-hospital and ICU case fatality rates decreased or remained stable in the four state capitals, especially in Manaus, and during the epidemic peak with the prevalence of the Gamma variant.RESUMO
Objetivo:
Descrever letalidade por COVID-19 hospitalar e em unidade de terapia intensiva (UTI) em quatro capitais brasileiras, em meses de picos epidêmicos e nos meses anteriores.Métodos:
Estudo ecológico com dados mensais de 2020-2021 do Sistema de Informação da Vigilância Epidemiológica da Gripe, em indivíduos com 20 anos ou mais. Estimou-se letalidade e mortalidade, com intervalos de confiança de 95%.Resultados:
Em Manaus, a letalidade em UTI nos >59 anos foi menor em dezembro/2020 (80,9% IC95% 78,4;83,3) e no pico de janeiro/2021 (79,9% IC95% 77,4;82,5), em comparação ao pico de abril/2020 (88,2% IC95% 86,1;90,3). Em São Paulo, Curitiba e Porto Alegre, observou-se queda ou estabilidade na letalidade hospitalar e em UTI, em janeiro/2021, em comparação ao mês de referência de 2020.Conclusão:
Em janeiro/2021, a letalidade hospitalar e em UTI caiu ou manteve-se estável nas quatro capitais, especialmente em Manaus e durante o pico epidêmico com predomínio da variante Gama.
