We assessed the efficacy of outpatient management for patients with SARS-CoV-2 related pneumonia at risk of progression after discharge from the emergency department.Methods This was a single-center prospective study. We enrolled patients with confirmed SARS-CoV-2 pneumonia, without hypoxemic respiratory failure, and at least one of the following: age \u226565 years or the presence of relevant comorbidities or pneumonia extension &gt;25% on high resolution computed tomography. Patients with pneumonia extension &gt;50% were excluded. An ambulatory visit was performed after at least 48 hours, when patients were either discharged, admitted, or deferred for a further visit. As a control, we evaluated a comparable historical cohort of hospitalized patients.Results A total of 84 patients were enrolled (51 male patients; mean age, 62.8 years). Two-thirds of the patients had at least one comorbidity and 41.6% had a lung involvement &gt;25% on high resolution computed tomography; the mean duration of symptoms was 8.0\u00b13.0 days, and the mean PaO2\/FiO2 ratio was 357.5\u00b138.6. At the end of the follow-up period, 69 patients had been discharged, and 15 were hospitalized (mean stay of 6 days). Older age and higher National Early Warning Score 2 were significant predictors of hospitalization at the first follow-up visit. One hospitalized patient died of septic shock. In the control group, the mean hospital stay was 8 days.Conclusion Adopting a \u201cdischarge and early revaluation\u201d strategy appears to be safe, feasible, and may optimize hospital resources during the SARS-CoV-2 pandemic.<\/jats:p>","DOI":"10.15441\/ceem.21.131","type":"journal-article","created":{"date-parts":[[2022,3,30]],"date-time":"2022-03-30T23:37:47Z","timestamp":1648683467000},"page":"10-17","update-policy":"https:\/\/doi.org\/10.15441\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Discharge
