AB  - Background A knowledge gap exists in understanding the beneficial use and duration of domiciliary supplemental oxygen (DSO) therapy among survivors of coronavirus disease 2019 (COVID-19) hospitalisations with persistent hypoxaemia upon discharge. The purpose of this single centre study was to begin to address this issue.Methods In this retrospective study we report features of US military veterans residing in metropolitan Chicago with no prior DSO therapy who survived COVID-19 hospitalisation, were discharged on DSO and were followed for 6 months.Results We found that the majority of the 65 elderly patients (median age, 70 years), predominantly obese Black males, who survived COVID-19 hospitalisations at the Jesse Brown VA Medical Center and were discharged on DSO did not undergo a formal 6-min walk test (6MWT) to re-assess ongoing ambulatory supplemental oxygen requirements (46 patients or 71%). Nonetheless, DSO therapy was discontinued in most patients predominantly within 8 weeks of hospital discharge (34 patients, 52%). In addition, a large proportion of patients, obese Black people in particular, who survived COVID-19 hospitalisations and were treated with DSO for at least 8 weeks thereafter developed post-acute sequelae of COVID-19 infection (PASC) (30 patients, 46%).Conclusions Given these findings, we recommend that healthcare providers be appraised about proper monitoring and evaluation, including timely performance of 6MWT, of patients who survived COVID-19 hospitalisations and were treated with DSO for persistent hypoxaemia upon discharge. Whether obese Black males who survived COVID-19 hospitalisations and are treated with DSO thereafter have an elevated risk in developing PASC remains to be determined in larger, prospective studies.A knowledge gap exists in understanding the beneficial use and duration of domiciliary supplemental O2 therapy among survivors of #COVID19 hospitalisation with persistent hypoxaemia upon discharge; hence, proper monitoring and evaluation are recommended https://bit.ly/3HRlfxE
