To the Editor In the recent study by Dr Lascarrou and colleagues1 comparing successful first-pass orotracheal intubation with video laryngoscopy vs direct laryngoscopy in patients in the ICU, we note several issues that were not well addressed.

First, defining physicians performing intubation as experts vs nonexperts based on the duration of work in the ICU was not a good way to compare their competence with the 2 studied devices because physicians are more likely to use direct laryngoscopy in routine practice, and experience with direct laryngoscopy does not equate to skill with video laryngoscopy.2 For results of a comparative study to be valid, physicians must be equally proficient with each device to avoid bias. We are concerned that the learning curves of physicians for the 2 devices might have contributed to the findings.
