Evaluation of the Outcome of COVID-19 Patients Discharged Home on Oxygen Therapy

The COVID-19 pandemic was responsible for an unprecedented hospital tension with multiple consequences (medical, economic, social...). The first scientific responses were found with unprecedented speed. Very quickly, innovative solutions and a complete reorganization of the health system were necessary to manage this crisis. In order to limit the number of patients hospitalized and/or the length of their hospitalization, most hospitals quickly set up systems to organize the early return of patients to their homes on oxygen. Studies evaluating telemedicine as a tool for monitoring oxygen-requiring patients at home have shown that it is effective and safe for monitoring these patients. Another retrospective study estimated the 30-day rehospitalization rate for patients with SARS-CoV-2 pneumonia after return home on oxygen with telephone monitoring by a nurse to be 8.5% (95% confidence interval, 6.2%-10.7%) and all-cause mortality to be 1.3% (95% confidence interval, 0.6%-2.5%).

The René Dubos Hospital in Pontoise has set up a home discharge system for oxygen-requiring patients in collaboration with PRADO, a health insurance organization, and a private provider. These organizations coordinate the care to be implemented at home based on the city/hospital link (oxygen provider, private nurse for the injection of anticoagulants and sometimes insulin and monitoring of vital parameters). These organizations were also in charge of scheduling a follow-up consultation between 7 and 14 days after hospital discharge, with the attending physician or, failing that, in the infectious diseases department of the Pontoise Hospital.
