| dc.description.abstract | Introduction: No protocol for assessing ultrasound imaging skill has been validated. We sought to develop and validate an assessment protocol for ultrasound imaging for the Focused Assessment with Sonography for Trauma. Methods: Our assessment tool consisted of task checklists, a global rating scale, and hand-motion analysis and was developed by a modified Delphi technique. Novice and expert cohorts were recruited to perform a FAST exam on a volunteer for assessment under the protocol. Results: Experts scored higher on static image acquisition (11.58 of 16 versus 6.63, p<0.0001), dynamic image acquisition (17.21 of 24 versus 11.08, p=0.0005), and our global rating scale (29.79 of 40 versus 18.42, p<0.0001); experts used fewer movements (263.0 movements versus 452.4, p=0.0216) and a shorter path length than novices (60.097 m versus 32.777 m, p=0.0041). Conclusion: Our protocol for assessing ultrasound imaging skill has criterion validity in assessing expertise and may lead to improvements to training and credentialing programs. | en_US |
