The goal of this systematic review and meta-analysis was to assess whether there is a difference in mortality rates between COVID-19 patients in the ICU who receive early intubation versus those who receive it later. The study also considered potential factors that could affect the results, such as patient characteristics and the length of time that mechanical ventilation was needed. A total of 18 studies were included in the final analysis, comprising a total of 11,228 patients. The meta-analysis did not find a statistically significant difference between the mortality in early versus late intubation, with a risk ratio of 0.97 (95% CI: 0.87-1.07). Subgroup analysis revealed that this result was consistent across various subgroups, including patient age and severity of illness. However, the included studies had moderate to high risk of bias and the possibility of publication bias cannot be ruled out. Further high-quality studies are needed to confirm these findings.
