        Implementation of clinical practice changes by experienced anesthesiologists after simulationbased ultrasound-guided regional anesthesia training

        T. Edward Kim,Edward R. Mariano,Toni Ganaway,T. Kyle Harrison,Steven K. Howard,Cynthia Shum,Alex Kuo 대한마취통증의학회 2017 Korean Journal of Anesthesiology Vol.70 No.3

        Background: Anesthesiologists who have finished formal training and want to learn ultrasound-guided regional anesthesia (UGRA) commonly attend 1 day workshops. However, it is unclear whether participation actually changes clinical practice. We assessed change implementation after completion of a 1 day simulation-based UGRA workshop. Methods: Practicing anesthesiologists who participated in a 1 day UGRA course from January 2012 through May 2014 were surveyed. The course consisted of clinical observation of UGRA procedures, didactic lectures, ultrasound scanning, hands-on perineural catheter placement, and mannequin simulation. The primary outcome was the average number of UGRA blocks per month reported at follow-up versus baseline. Secondary outcomes included preference for ultrasound as the nerve localization technique, ratings of UGRA teaching methods, and obstacles to performing UGRA. Results: Survey data from 46 course participants (60% response rate) were included for analysis. Participants were (median [10th–90th percentile]) 50 (37–63) years old, had been in practice for 17 (5–30) years, and were surveyed 27 (10–34) months after their UGRA training. Participants reported performing 24 (4–90) blocks per month at follow-up compared to 10 (2–24) blocks at baseline (P < 0.001). Compared to baseline, more participants at follow-up preferred ultrasound for nerve localization. The major obstacle to implementing UGRA in clinical practice was time pressure. Conclusions: Participation in a 1 day simulation-based UGRA course may increase UGRA procedural volume by practicing anesthesiologists.

        Using eye tracking technology to compare the effectiveness of malignant hyperthermia cognitive aid design

        Roderick King,Jaber Hanhan,T. Kyle Harrison,Alex Kou,Steven K. Howard,Lindsay K. Borg,Cynthia Shum,Ankeet D. Udani,Edward R. Mariano 대한마취통증의학회 2018 Korean Journal of Anesthesiology Vol.71 No.4

        Background: Malignant 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. Methods: With 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. Results: For 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. Conclusions: This 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.
