Brief Summary

Eye tracking is the process of measuring an individual's eye movements in order to reflect their attentional behavior by using a device called an eye- tracker.

This study uses eye-tracking methodology to observe the gaze patterns of participants to a high fidelity simulation scenario of postpartum hemorrhage acting in the role of leader to evaluate the relationship between eye-tracking patterns and leadership and team behavioral and technical skills.

Detailed Description

This study will include 5 groups of anesthesia trainees consisting of 5 participants each. Each group will practice a standardized high-fidelity scenario on postpartum hemorrhage (PPH) which will be repeated for four times. All the scenarios will be video recorded.

All groups will receive a technical briefing on the PPH guidelines before the scenario, and after having assigned to each participant a role (leader anesthesiologist, junior anesthesiologist, obstetrician, and midwife) they will practice a standardized 15 minutes scenario with a high fidelity manikin. A debriefing with an expert debriefer will be performed after each scenario.

The participant acting as the leader will practice the scenario while wearing a pair of eye-tracking glasses (Tobii Pro Glasses 50 Hz wearable wireless eye-tracker). All the eye-tracking video-recordings will be stored and analyzed by using a Tobii Pro Lab Software. Specific areas of interest (AOI), to define regions of a displayed stimulus, and to extract metrics specifically for those regions will be selected. Number and duration of fixations, visit counts and their duration for each area of interest and for each scenario will be examined. Eye-tracking metrics will be mapped as gaze plots and heat maps. Two independent observers will review the scenario video recordings and will assing a score to the leader and team behavioral and technical skills. These scores will be correlated to eye tracking metrics.

Interventions

Tobii Pro Glasses 50 Hz wearable wireless eye tracker

This system can measure eye movements using cameras integrated into the eyeglasses which record the corneal reflection of infrared lighting to track pupil position, mapping the subject's focus of attention on video recordings of the subject's field of vision (gaze).
