Description
Background: POCUS education and competency milestones are required for emergency medicine residency graduation. Currently, POCUS competency is assessed using OSCEs. This approach is non-standardized, subjective, and resource intensive. In this pilot study we determine the ability of head motion analysis to differentiate between novice-and-expert-level POCUS performance. Methods: Fifteen emergency medicine physicians, eight novice POCUS users and nine experts, performed cardiac and FAST exams. Head motion was tracked using Muse2-headband with accelerometer and gyroscope sensors. Fellowship-trained experts observed all exams and independently recorded OSCE scores. Results: Experts scored higher in OSCEs than novices in both examinations (p<0.00001). Experts demonstrated less head motion distribution in the X,Y and Z-directions, with significant differences (p<0.001) between expert and novice groups. Conclusions: Head-motion metrics can differentiate novice-and expert-level ultrasonographers, which could offer objective competency assessments for new POCUS learners. Additional studies are needed to identify minimum threshold values for defining competency based on these metrics.
