Abstract
AIM
To assess visual attention of neonatal team leaders during delivery room resuscitation of preterm infants using eye tracking glasses.
METHODS
Prospective observational eye tracking study. Gaze fixations and sequences were captured, categorized, and mapped during the first 5 min of the resuscitations. Gaze fixation metrics of total gaze duration, visit count, and visit duration were summarized and compared based on interventions performed and provider training level. Fixation sequences were compared between attending neonatologists and fellows.
RESULTS
During 18 eye tracking recordings, practitioners focused most of their cumulative visual attention on the infant (median total gaze duration 57%, interquartile range [IQR] 38-61%), followed by monitors (24%, IQR 13-46%), clinical staff (5%, IQR 1-8%), other physical objects (4%, IQR 3-6%), T-piece resuscitator (2%, IQR 0-4%) and the Apgar timer (1%, IQR 0-2%). Visual attention parameters varied according to intervention, with higher visit counts on the infant during corrective ventilation steps than during Continuous Positive Airway Pressure (CPAP) or Positive Pressure Ventilation (PPV), and longer visit durations on monitors during PPV. Time and frequency-based measures of visual attention did not significantly differ by provider training level, but patterned fixation sequences were identified among attending neonatologists that were not observed in fellows.
CONCLUSION
Team leaders predominantly gazed upon the infant and monitors during resuscitation, and visual attention parameters varied depending on the respiratory interventions performed. Attending neonatologists exhibited patterned fixation sequences that were not observed in fellows. Study results may have implications for optimizing delivery room design and training novice providers.
