Question and Methods: Systematic review and meta-analysis evaluating if checklist use during endotracheal intubation leads to improved patient outcomes.
Findings: The authors found no difference in their primary outcome of mortality or any secondary outcomes when assessing studies with low risk of bias.
Limitations: The major limitation of this review is the poor quality of the included studies – with most being of before-after observational design at high risk of bias.
Interpretation: Due to the high risk of bias of included studies, the results of this review should not alter our practice at this time. Absence of evidence does not equal a lack of benefit, and further RCTs are required to further investigate checklist utility.
