Mortality risk model validation in a prospective cohort of patients from the sixth wave of the COVID-19 pandemic in a hospital emergency department.

Objectives: To validate risk factors for mortality in patients treated for COVID-19 in a hospital emergency department during the sixth wave of the pandemic.

Material And Methods: Prospective observational noninterventional study. We included patients over the age of 18 years with a confirmed diagnosis of COVID-19 between December 1, 2021, and February 28, 2022.

Risk score for mortality due to COVID-19: a prospective temporal validation cohort study in the emergency department of a tertiary care hospital.

Objectives: To validate a previously described hospital emergency department risk model to predict mortality in patients with COVID-19.

Material And Methods: Prospective observational noninterventional study. Patients aged over 18 years diagnosed with COVID-19 were included between December 1, 2020, and February 28, 2021.

Mortality in patients treated for COVID-19 in the emergency department of a tertiary care hospital during the first phase of the pandemic: Derivation of a risk model for emergency departments.

Objectives: To develop a risk model to predict 30-day mortality after emergency department treatment for COVID-19.

Material And Methods: Observational retrospective cohort study including 2511 patients with COVID-19 who came to our emergency department between March 1 and April 30, 2020. We analyzed variables with Kaplan Meier survival and Cox regression analyses.

Factors associated with revisits by patients with SARS-CoV-2 infection discharged from a hospital emergency department.

Objectives: To analyze emergency department (ED) revisits from patients discharged with possible coronavirus disease 2019 (COVID-19).

Material And Methods: Retrospective observational study of consecutive patients who came to the ED over a period of 2 months and were diagnosed with possible COVID-19. We analyzed clinical and epidemiologic variables, treatments given in the ED, discharge destination, need to revisit, and reasons for revisits.
