Abstract
Background: We attempted to investigate the change in mortality of intubated patients with coronavirus disease (COVID-19) from first to subsequent waves across several countries.
Methods: We pre-registered our meta-analysis with PROSPERO [Anonymized]. We searched PubMed, Scopus and grey literature for observational studies reporting data on all-cause mortality of intubated patients with COVID-19 recruited both during first and subsequent waves of the pandemic. We considered studies published after August 31[SUP]st[/SUP], 2020 up to July 12[SUP]th[/SUP], 2021. The primary outcome of the meta-analysis was all-cause mortality. We used a random effects model to calculate pooled risk ratio (RR) and 95% confidence intervals (CI).
Results: : By incorporating data of 363660 patients from 43 countries included in 28 studies, we found that all-cause mortality of intubated patients with COVID-19 increased from first to subsequent waves (from 62.2% to 72.6%; RR 0.90, 95% CI 0.85-0.94, p <0.00001). This finding was independent of the geo-economic variation of the included studies and persisted in several pre-specified subgroup and sensitivity analyses.
Conclusions: : The robust finding of this meta-analysis suggests that mortality of intubated patients with COVID-19 did not improve over time. Future research should target this group of patients to further optimize their management.
