“…At 8 weeks after hospital discharge, 52% of patients no longer required supplemental oxygen. 11 According to followup reports at 60 days after hospital discharge in another study in the United States, 2.6% of patients required supplemental oxygen. In that study, 13.2% of the included patients had been admitted to the ICU.…”

Objective We aimed to describe the prevalence and factors associated with the need for supplemental oxygen and persistent symptoms 1 year after severe SARS-CoV-2 infection. Methods In this historical cohort and nested case–control study, we included adults with severe COVID-19 (requiring admission to the intensive care unit or invasive mechanical ventilation). We evaluated factors associated with a need for supplemental oxygen and persistent symptoms 1 year after severe infection. Results We included 135 patients (median age 62 years, 30% women). At 1-year follow-up, the main symptoms were dyspnea (32%), myalgia (9%), cough (7%), anxiety (4%), and depression (5%); 12.59% of patients had prolonged requirement for supplemental oxygen. Factors associated with a persistent requirement for supplemental oxygen were female sex (odds ratio 3.15, 95% confidence interval 1.11–8.90) and Charlson Comorbidity Index > 4 (odds ratio 1.60, 95% confidence interval 1.20–2.12). Conclusions We found that a high prevalence of supplemental oxygen requirement 1 year after severe COVID infection was associated with female sex and a baseline high rate of comorbidities. It is unknown whether this prevalence was related to other factors, such as the altitude at which patients lived. More than half of patients had prolonged post-COVID syndrome.

“…As approximately 15% of hospitalized patients need oxygen, clinically stable patients with ongoing oxygen requirements are discharged with an oxygen concentrator. 4,5 While many studies explore factors associated with the need for oxygen concentrators, there's a limited number of studies assessing the availability of the device and its long-term usage. 4,5 This study aimed to identify factors associated with the necessity for oxygen concentrators upon discharge of COVID-19 patients, alongside investigating device acquisition and mortality rates.…”

Aims: The COVID-19 pandemic has severely burdened healthcare systems worldwide due to the rapid rise in cases, often resulting in respiratory distress requiring oxygen therapy. However, research on the availability and long-term usage of oxygen concentrators upon discharge is limited. This study aimed to identify factors associated with the need for oxygen concentrators in discharged COVID-19 patients, as well as device acquisition and mortality rates. Methods: This study, conducted at a single center, comprised retrospective and prospective phases. Data were gathered from hospitalized COVID-19 patients, with follow-up conducted one year later for those prescribed oxygen concentrators at discharge. Sociodemographic and clinical variables were recorded, and statistical analyses were conducted to determine factors associated with oxygen concentrator need and duration of use. Results: Among 229 patients, 15.7% required oxygen concentrators at discharge. Factors associated with this need included older age, asthma, bilateral lung lesions, and the severity of lesions detected on thoracic computed tomography scans. Patients with corticosteroid use and hypertension required oxygen concentrators for over three months. Economic limitations impeded the acquisition of devices for 22.2% of patients who were prescribed them. Two to three months post-discharge, 72.2% of patients still used oxygen concentrators. Mortality analysis showed a 16.6% fatality rate among oxygen concentrator prescribed patients within one year, with shorter survival observed in those unable to obtain the device. Conclusion: This study highlights the significance of assessing factors impacting oxygen concentrator requirement in COVID-19 patients and their long-term prognosis. These findings should inform healthcare providers and policymakers in pandemic preparedness efforts, emphasizing tailored treatment approaches based on individual patient characteristics. Ensuring device accessibility and regular patient follow-up are crucial for optimizing healthcare delivery during similar crises.

“…Therefore, medical oxygen is a critical element in the treatment of patients with COVID-19 (Saadatmand et al, 2022 ), as active oxygen therapy to treat hypoxia is important for positive patient outcomes. Moreover, patients who survived hospitalization due to COVID-19 received additional oxygen treatment at home to treat persistent hypoxemia after discharge (Kaul et al, 2022 ). Consequently, to date, no long-term comparative study on the quality of life in post-COVID-19 subjects with different disease severity at hospital admission has been conducted.…”

Comparative study of quality of life 9 months post-COVID-19 infection with SARS-CoV-2 of varying degrees of severity: impact of hospitalization vs. outpatient treatment

PurposeThis experimental study was conducted during the post-COVID-19 period to investigate the relationship between the quality of life 9 months after and the severity of the SARS-CoV-2 infection in two scenarios: hospitalization (with/without medical oxygen) and outpatient treatment.MethodsWe employed the EQ-5D-5L Quality of Life tests and the PSQI as a survey to evaluate respondents' quality of life 9 months after a previous SARS-CoV-2 infection of varying severity.ResultsWe identified a clear difference in the quality of life of respondents, as measured on the 100-point scale of the EQ-5D-5L test, which was significantly lower 9 months after a previous SARS-CoV-2 infection for Group 1 (n = 14), respondents who had received medical attention for SARS-CoV-2 infection in a hospital with oxygen treatment, compared to those with the SARS-CoV-2 infection who were treated without oxygen treatment (Group 2) (n = 12) and those who were treated on an outpatient basis (Group 3) (n = 13) (H = 7.08 p = 0.029). There were no intergroup differences in quality of life indicators between hospitalized patients (Group 2) and groups 1 and 3. PSQI survey results showed that “mobility,” “self-care,” “daily activities,” “pain/discomfort,” and “anxiety/ depression” did not differ significantly between the groups, indicating that these factors were not associated with the severity of the SARS-CoV-2 infection. On the contrary, the respondents demonstrated significant inter-group differences (H = 7.51 p = 0.023) and the interdependence of respiratory difficulties with the severity of clinically diagnosed SARS-CoV-2 infection. This study also demonstrated significant differences in the values of sleep duration, sleep disorders, and daytime sleepiness indicators between the three groups of respondents, which indicate the influence of the severity of the infection. The PSQI test results revealed significant differences in “bedtime” (H = 6.00 p = 0.050) and “wake-up time” (H = 11.17 p = 0.004) between Groups 1 and 3 of respondents. At 9 months after COVID-19, respondents in Group 1 went to bed at a later time (pp = 0.02727) and woke up later (p = 0.003) than the respondents in Group 3.ConclusionThis study is the first of its kind in the current literature to report on the quality of life of respondents 9 months after being diagnosed with COVID-19 and to draw comparisons between cohorts of hospitalized patients who were treated with medical oxygen vs. the cohorts of outpatient patients. The study's findings regarding post-COVID-19 quality of life indicators and their correlation with the severity of the SARS-CoV-2 infection can be used to categorize patients for targeted post-COVID-19 rehabilitation programs.
