Procalcitonin concentration in the emergency department predicts 30-day mortality in COVID-19 better than the lymphocyte count, the neutrophil-tolymphocyte ratio, or the C-reactive protein level.

Objectives: Although many demographic and clinical predictors of mortality have been studied in relation to COVID-19, little has been reported about the prognostic utility of inflammatory biomarkers.

Material And Methods: Retrospective cohort study. All patients with laboratory-confirmed COVID-19 treated in a hospital emergency department were included consecutively if baseline measurements of the following biomarkers were on record: lymphocyte counts, neutrophil-to-lymphocyte ratio NRL, and C-reactive protein (CRP) and procalcitonin (PCT) levels.

Diagnostic groups and short-term outcomes in suspected COVID-19 cases treated in an emergency department.

Objectives: The primary objective was to describe the clinical characteristics and 30-day mortality rates in emergency department patients with coronavirus disease 2019 (COVID-19) in different diagnostic groupings.

Material And Methods: Secondary analysis of the COVID-19 registry compiled by the emergency department of Hospital Clínico San Carlos in Madrid, Spain. We selected suspected COVID-19 cases treated in the emergency department between February 28 and March 31, 2020.

Clinical presentation and outcome across age categories among patients with COVID-19 admitted to a Spanish Emergency Department.

Purpose: To determine the differences by age-dependent categories in the clinical profile, presentation, management, and short-term outcomes of patients with laboratory-confirmed COVID-19 admitted to a Spanish Emergency Department (ED).

Methods: Secondary analysis of COVID-19_URG-HCSC registry. We included all consecutive patients with laboratory-confirmed COVID-19 admitted to the ED of the University Hospital Clinico San Carlos (Madrid, Spain).

Physical frailty and its impact on long-term outcomes in older patients with acute heart failure after discharge from an emergency department.

Objectives: To study the frequency of physical frailty and explore whether its presence in older patients with acute heart failure (AHF) is associated with adverse outcomes in the year after discharge from a emergency department (ED).

Material And Methods: Prospective observational cohort study in patients with AHF aged 75 years or older who were discharged from our ED. Physical frailty was defined by a score of 7 or less on the Short Physical Performance Battery.
