Novel Use of Home Pulse Oximetry Monitoring in COVID‐19 Patients Discharged From the Emergency Department Identifies Need for Hospitalization

Objectives Our objective was to evaluate patient‐reported oxygen saturation (SpO2) using pulse oximetry as a home monitoring tool for patients with initially nonsevere COVID‐19 to identify need for hospitalization. Methods Patients were enrolled at the emergency department (ED) and outpatient testing centers. Each patient was given a home pulse oximeter and instructed to record their SpO2 every 8 hours. Patients were instructed to return to the ED for sustained home SpO2
