Observed standardized clinical exams (OSCE) are essential to ensure skills are sufficiently learned. However this is time consuming and hard to do for large groups of learners. To address this problem we developed an ultrasound image acquisition OSCE with asynchronous but timely feedback via cloud stored images and a standardized grading rubric that greatly reduced the time needed. We did so by having 129 students complete an ultrasound OSCE in a test environment and submit images to the cloud. Images were graded asynchronously by a single faculty member using a standardized rating system with narrative feedback from images scoring less than full points. Faculty time to evaluate all student images was 10.5 hours. The average score was 25.8 out of 28. Only 3 images out of the 903 total images had to be remediated. All three students obtained adequate remediation images using only the narrative feedback from faculty and their own self study. An ultrasound OSCE with asynchronous feedback made performing the assessment feasible from a faculty standpoint by reducing the time required to perform a large scale ultrasound OSCE by 83%. More than 99.9% of images were performed sufficiently using this method, making it feasible for students also.
