A study published in the Journal of the American Society of Echocardiography suggests that an educational discussion about echocardiograms in which visual ejection fraction estimations vary can decrease interobserver variability and improve the accuracy of subsequent evaluations. When a group of sonographers and cardiologists met to discuss the results of echo EF measurements, they focused on the cases with high interobserver variability and talked about ways to improve image reading. A month later, the same group demonstrated greater agreement and accuracy, and estimates were better when both cardiologists and sonographers made estimates.
