Multicenter Study
A 4C mortality score based dichotomic rule supports Emergency Department discharge of COVID-19 patients.
For COVID-19 patients evaluated in the Emergency Department (ED), decision on hospital admission vs. home discharge is challenging. The 4C mortality score (4CMS) is a prognostication tool integrating key demographic/clinical/biochemical data validated for COVID-19 inpatients. We sought to derive and validate a dichotomic rule based on 4CMS identifying patients with mild outcomes, suitable for safe ED discharge. ⋯ COVID-19 outpatients with 4CMS≤8 have mild outcomes and can be safely discharged from the ED.
