PURPOSE: Optimal timing of intubation is controversial. We attempted to investigate the association between timing of intubation and clinical outcomes of critically ill patients. METHODS: PubMed was systematically searched for studies reporting on mortality of critically ill patients undergoing early versus late intubation. Studies involving patients with new coronavirus disease (COVID-19) were excluded because a relevant meta-analysis has been published. "Early" intubation was defined according to the authors of the included studies. All-cause mortality was the primary outcome. Pooled risk ratio (RR) and 95% confidence intervals (CI) were calculated using a random effects model. The meta-analysis was registered with PROSPERO (CRD42021284850). RESULTS: In total, 27 studies involving 15,441 intubated patients (11,943 early, 3498 late) were included. All-cause mortality was lower in patients undergoing early versus late intubation (7338 deaths; 45.8% versus 53.5%; RR 0.92, 95% CI 0.87-0.97; p = 0.001). This was also the case in the sensitivity analysis of studies defining "early" as intubation within 24 h from admission in the intensive care unit (6279 deaths; 45.8% versus 53.6%; RR 0.93, 95% CI 0.89-0.98; p = 0.005). CONCLUSION: Avoiding late intubation may be associated with lower mortality in critically ill patients without COVID-19.

BACKGROUND: Although older adults aret ahigh risk for severe coronavirus disease 2019 (COVID-19) requiring intensive care unit (ICU) admission, age is often used as a selection criterion in case of ICU beds scarcity. We sought to compare the proportion, clinical features and mortality between patients ≥70 years old and younger ICU patients with COVID-19. METHODS: All patients, consecutively admitted to our COVID ICU, where age was not used as an admission criterion, from March 2020 through April 2021, were included. Demographics, clinical and laboratory characteristics were recorded. Illness severity and Charlson comorbidity índex (CCI) were calculated. Patients≥70 years old were compared to youngers. RESULTS: Of 458 patients [68 (59-76) years, 70% males], 206 (45%) were≥70 years old. Compared to younger, older patients had higher illness severity scores [APACHE II 18 (14-23) versus 12 (9-16), p<0.001, SOFA 8 (6-10) versus 6 (2-8), p<0.001, CCI 5 (4-6) versus 2 (1-3), p <0.001], increased need for mechanical ventilation (92% vs 72%, p<0.001) and ICU mortality (74% versus. 29%, p<0.001). Age (HR: 1.045, CI: 1.02-1.07, p=0.001), CCI (HR: 1.135, CI: 1.037-1.243, p=0.006) and APACHE I I (HR: 1.070, CI: 1.013-1.130, p=0.015) were independently associated with mortality. Among comorbidities, obesity, chronic pulmonary disease and chronic kidney disease were independent risk factors for death. CONCLUSIONS: When age is not used as criterion for admission to COVID ICU, patients≥70 years old represent a considerable proportion and, compared to younger ones, they have higher mortality. Age, severity of illness and CCI, and certain comorbidities are independent risk factors for mortality.
