Intubation checklists have been widely adopted for use during endotracheal intubation in hopes of increasing the safety of this high-risk procedure, but their effect on outcomes is not clear. These researchers performed a systematic review and meta-analysis of 11 heterogenous studies (3261 patients) that assessed the effect of various intubation checklists, with or without additional interventions, on mortality and other outcomes. Only one study was randomized.
Use of a checklist was not associated with decreased mortality in the five studies that assessed this outcome (relative risk, 0.97). In the eight studies that assessed hypoxic events, checklist use was associated with reduced risk for hypoxia (RR, 0.75); however, when the authors pool…
