“…The answer to each question was always a specific location on the cognitive aid, defined as the AOI. The five MH cognitive aids selected were freely available [ 1 ] and previously published by the following groups: 1) The Association of Anaesthetists of Great Britain and Ireland (AAGBI) [ 13 , 14 ]; 2) Ariadne Labs [ 5 ]; 3) the Malignant Hyperthermia Association of the United States (MHAUS) [ 9 ]; 4) the Society for Pediatric Anesthesia (SPA) [ 3 ]; and 5) Stanford Anesthesia Cognitive Aid Group [ 4 ]. The sequence of slides (cognitive aids and questions) were ordered randomly using an online tool ( http://www.randomizer.org ).…”

BackgroundMalignant hyperthermia is a rare but potentially fatal complication of anesthesia, and several different cognitive aids designed to facilitate a timely and accurate response to this crisis currently exist. Eye tracking technology can measure voluntary and involuntary eye movements, gaze fixation within an area of interest, and speed of visual response and has been used to a limited extent in anesthesiology.MethodsWith eye tracking technology, we compared the accessibility of five malignant hyperthermia cognitive aids by collecting gaze data from twelve volunteer participants. Recordings were reviewed and annotated to measure the time required for participants to locate objects on the cognitive aid to provide an answer; cumulative time to answer was the primary outcome.ResultsFor the primary outcome, there were differences detected between cumulative time to answer survival curves (P < 0.001). Participants demonstrated the shortest cumulative time to answer when viewing the Society for Pediatric Anesthesia (SPA) cognitive aid compared to four other publicly available cognitive aids for malignant hyperthermia, and this outcome was not influenced by the anesthesiologists’ years of experience.ConclusionsThis is the first study to utilize eye tracking technology in a comparative evaluation of cognitive aid design, and our experience suggests that there may be additional applications of eye tracking technology in healthcare and medical education. Potentially advantageous design features of the SPA cognitive aid include a single page, linear layout, and simple typescript with minimal use of single color blocking.
