Eye-tracking during simulated endotracheal newborn intubation: a prospective, observational multi-center study.

BACKGROUND: The aim was to assess health care providers' (HCPs) visual attention (VA) by using eye-tracking glasses during a simulated neonatal intubation. METHODS: HCPs from three pediatric and neonatal departments (Feldkirch and Vienna, Austria, and Edmonton, Canada) completed a simulated neonatal intubation scenario while wearing eye-tracking glasses (Tobii Pro Glasses 2®, Tobii, Stockholm, Sweden) to record their VA. Main outcomes included duration of intubation, success rate, and VA. We further compared orotracheal and nasotracheal intubations. RESULTS: 30 participants were included. 50% completed the intubation within 30 s (M = 35.40, SD = 16.01). Mostly nasotracheal intubations exceeded the limit. Experience was an important factor in reducing intubation time. VA differed between more and less experienced HCPs as well as between orotracheal and nasotracheal intubations. Participants also focused on different areas of interest (AOIs) depending on the intubator's experience. More experience was associated with a higher situational awareness (SA) and fewer distractions, which, however, did not transfer to significantly better intubation performance. CONCLUSION: Half of the intubations exceeded the recommended time limit. Differences in intubation duration depending on type of intubation were revealed. VA differed between HCPs with different levels of experience and depended on duration and type of intubation. IMPACT: Simulated neonatal intubation duration differs between orotracheal and nasotracheal intubation. Visual attention during simulated neonatal intubation shows differences depending on intubation duration, intubator experience, type of intubation, and level of distraction. Intubator experience is a vital parameter for reducing intubation duration and improving intubator focus on task-relevant stimuli.
