Study of COVID-19 Prognostic Factors in Hospitalized Patients

Severe COVID-19 prognostic factors have been studied worldwide throughout the pandemic, but there is considerable variability. Therefore, the investigators will summarize the identified prognostic factors in the international literature and will conduct a retrospective cohort study to identify the prognostic factors of severe COVID-19 in hospitalized patients of the Hospital de la Santa Creu i Sant Pau in Barcelona (Spain) between March 2020 and February 2021, compare them with those mentioned in the international literature and establish those most adequate to our population.
