To the Editor Dr Andersen and colleagues reported that tracheal intubation vs no intubation among children with in-hospital cardiac arrest was associated with decreased survival.1 The data were drawn from the American Heart Association’s Get With the Guidelines—Resuscitation (GWTG-R) registry. However, the time-interval data were of poor quality.
Figure 2 in the article shows that 7% of the intubations were recorded as having occurred at 0 minutes. The authors explained that 0 minutes meant within 60 seconds of the start of cardiopulmonary resuscitation, but that does not seem plausible.2
