The awake prone position (AP) strategy for patients with acute respiratory distress syndrome (ARDS) is a safe, simple, and cost-effective technique used to improve hypoxemia. We aimed to evaluate intubation and mortality risk in patients with coronavirus disease (COVID-19) who underwent AP during hospitalisation.In this retrospective, multicentre observational study conducted between May 1 and June 12, 2020 in 27 hospitals in Mexico and Ecuador, non-intubated patients with COVID-19 managed with AP or supine positioning were included to evaluate intubation and mortality risk through logistic regression models; multivariable and centre adjustment, propensity score analyses, and E-values were calculated to limit confounding. This study was registered at https://clinicaltrials.gov/ct2/show/NCT04407468827 non-intubated patients with COVID-19 in the AP (n=505) and supine (n=322) groups were included for analysis. Less patients in the AP group required endotracheal intubation (23.6% versus 40.4%) or died (20% versus 37.9%). AP was a protective factor for intubation even after multivariable adjustment (OR=0.39, 95%CI: 0.28–0.56, p<0.0001, E-value=2.01), which prevailed after propensity score analysis (OR=0.32, 95%CI: 0.21–0.49, p<0.0001, E-value=2.21), and mortality (adjusted OR=0.38, 95%CI: 0.25–0.57, p<0.0001, E-value=1.98). The main variables associated with intubation amongst AP patients were increasing age, lower baseline SpO2/FiO2, and management with a non-rebreather mask.AP in hospitalised non-intubated patients with COVID-19 is associated with a lower risk of intubation and mortality.

PurposeThe awake prone position (PP) strategy for patients with acute respiratory distress syndrome (ARDS) is a safe, simple, and cost-effective technique used to improve hypoxemia. We aimed to evaluate the relationship between awake PP (AP) and endotracheal intubation in patients with coronavirus disease (COVID-19).MethodsIn this retrospective, multicentre observational study conducted between 1 May and 12 June 2020 in 27 hospitals in Mexico and Ecuador, non-intubated patients with COVID-19 managed with AP or awake supine positioning (AS) were included to evaluate intubation and mortality risk in AP patients through logistic regression models; multivariable adjustment, propensity score analyses, and E-values were calculated to limit confounding. A CART model with cross-validation was also built. This study was registered at https://clinicaltrials.gov/ct2/show/NCT04407468Results827 non-intubated patients with COVID-19 in the AP (n=505) and AS (n=322) groups were included for analysis. Less patients in the AP group required endotracheal intubation (23.6% vs 40.4%) or died (20% vs 37.9%). AP was a protective factor for intubation even after multivariable adjustment (OR=0.39, 95%CI:0.28-0.56, p<0.0001, E-value=2.01), which prevailed after propensity score analysis (OR=0.32, 95%CI:0.21-0.49, p<0.0001, E-value=2.21), and mortality (adjusted OR=0.38, 95%CI:0.25-0.57, p<0.0001, E-value=1.98). The main variables associated with PP failure in AP patients were age, lower SpO2/FiO2, and management with a non-rebreather mask. In the CART model, only two variables were used: SpO2/FiO2 (F 97.7, p<0.001) and PP (X2 50.5, p<0.001), with an overall percentage of 75.2%.ConclusionPP in awake hospitalised patients with COVID-19 is associated with a lower risk of intubation and mortality.

Objective: Determine whether the levels of glycated hemoglobin (HbA1c) measured on admission to the intensive care unit (ICU) are associated with mortality in patients with severe SARS-CoV-2 pneumonia with invasive mechanical ventilation. Design: Cohort study, retrospective, observational. A single center. Place: ICU of a second-level care hospital. Patients: Severe SARS-CoV-2 pneumonia confirmed with IMV since admission to the ICU. Interventions: none. Results: A total of 56 patients with severe pneumonia, confirmed with SARS-CoV-2, all with IMV. The group with HbA1c <6.5% included 32 (57.14%) patients and the group with HbA1c ≥6.5% included 24 (42.86%) patients and the mortality rate in ICU was 43.8% and 70.8%, respectively, with p = 0.04. Predictors of mortality at 28 days in ICU were DHL >500 U/L, OR 3.65 (95% CI 1.18-11.29), HbA1c ≥6.5%, OR 3.12 (95% CI 1.01-9.6), SAH, OR 3.12 (95% CI 1.01-9.5), use of vasopressor, OR 0.2 (95% CI 0.05-0.73), diabetes was not statistically significant. Conclusion:The 28-day probability of survival in patients with severe SARS-CoV-2 pneumonia with IMV in the ICU is lower when the HbA1c level is ≥6.5% on admission.
