Interactive online learning tools have revolutionized graduate medical education and can impart echocardiographic image interpretive skills. We created self-paced, interactive online training modules using a repository of echocardiography videos of normal and various degrees of abnormal left ventricles. In this study, we tested the feasibility of this learning tool. Thirteen anesthesia interns took a pre-test and then had 3 weeks to complete the training modules on their own time before taking a post-test. The average score on the post-test (74.6% ± 11.08%) was higher than the average score on the pre-test (57.7% ± 9.27%) ( < 0.001). Scores did not differ between extreme function (severe dysfunction or hyperdynamic function) and non-extreme function (normal function or mild or moderate dysfunction) questions on both the pre-test ( = 0.278) and post-test ( = 0.093). The interns scored higher on the post-test than the pre-test on both extreme ( = 0.0062) and non-extreme ( = 0.0083) questions. After using an online educational tool that allowed learning on their own time and pace, trainees improved their ability to correctly categorize left ventricular systolic function. Left ventricular systolic function is often a key echocardiographic question that can be difficult to master. The promising performance of this educational resource may lead to more time- and cost-effective methods for improving diagnostic accuracy among learners.
交互式在线学习工具彻底改变了研究生医学教育，并能传授超声心动图图像解读技能。我们利用正常及不同程度异常左心室的超声心动图视频库创建了自主学习的交互式在线培训模块。在本研究中，我们测试了这种学习工具的可行性。13名麻醉科实习生进行了一次预测试，然后有3周时间在自己方便的时间完成培训模块，之后再进行一次后测试。后测试的平均成绩（74.6%±11.08%）高于预测试的平均成绩（57.7%±9.27%）（<0.001）。在预测试（=0.278）和后测试（=0.093）中，极端功能（严重功能障碍或高动力功能）和非极端功能（正常功能或轻度或中度功能障碍）问题的得分没有差异。实习生在极端（=0.0062）和非极端（=0.0083）问题的后测试中得分均高于预测试。在使用了一个允许按照自己的时间和节奏进行学习的在线教育工具后，学员们提高了正确分类左心室收缩功能的能力。左心室收缩功能常常是一个关键的超声心动图问题，可能难以掌握。这种教育资源的良好表现可能会带来更具时间和成本效益的方法，以提高学习者的诊断准确性。
