“…In addition, the intubation periods in survivors and nonsurvivors were 12.1 days and 10 days, respectively. In contrast, previously reported intubation periods in ICU patients, including postoperative patients, chronic obstructive pulmonary disease (COPD) patients, pneumocystis pneumonia survivors, acute respiratory distress syndrome (ARDS) patients, communityacquired pneumonia patients, and SARS-CoV-1 pneumonia survivors, were 3.3 ± 3 days (mortality 24.3%) (119), 6.8 ± 4.9 days (mortality 13%) (120), 7.7 ± 8.2 days (121), 8.8 (± 6) days ( 122), 10-11 days (123), 12.1 ± 6.1 days (124), and 7.3-15 days (mean days are calculated from each original datum) (125)(126)(127), respectively. One study comparing COVID-19 with influenza found that the intubation period in COVID-19 patients was longer than that in influenza patients (16.2 vs. 7.3 days) (127).…”

Purpose: There is no clear consensus on the clinical course of critical COVID-19 patients. We examined the clinical course among intubated survivors, non-survivors, and extracorporeal membrane oxygenation (ECMO) patients to reveal the standard clinical course and the difference among critical COVID-19 patients.Methods: In this systematic review and meta-analysis, we searched PubMed, Web of Science, and Scopus for original studies published until December 11, 2020, including case accumulation and clinical course reporting. Pregnant patients and children were excluded. We followed PRISMA guidelines and registered them with PROSPERO (CRD42021235534).Results: Of the 11,716 studies identified, 94 met the selection criteria, and 2,549 cases were included in this meta-analysis. The times from intubation to extubation and death were 12.07 days (95% confidence interval 9.80–14.33 days) and 10.14 days (8.18–12.10 days), respectively, and the ECMO duration was 14.72 days (10.57–18.87 days). The time from symptom onset to hospitalization (prehospitalization period) of intubated survivors, non-survivors, and ECMO patients was 6.15 (4.61–7.69 days), 6.45 (4.55–8.34 days), and 7.15 days (6.48–7.81 days), and that from symptom onset to intubation (preintubation period) was 8.58 (7.36–9.80 days), 9.14 (7.26–11.01 days), and 10.54 days (9.18–11.90 days), respectively. Sensitivity analysis showed that the time from intubation to extubation and death was longer in the US and Europe than in East Asia.Conclusion: For COVID-19, we hypothesize that prehospitalization and preintubation periods are longer in intubated non-survivors and ECMO patients than in intubated survivors. These periods may serve as a predictor of disease severity or death and support therapeutic strategy determination.
