Video clip training improved emergency medicine residents’ interpretation ability of visual ejection fraction:

Background:Information on cardiac contractility is very important in resuscitation of critically ill patients. However, the measurement of ejection fractions by echocardiography is very difficult to perform for non-cardiologists. We developed a video clip to train emergency medicine residents to measure visual ejection fraction and compared the improvement in their interpretation ability with that following the conventional training method.Objectives:Improvement of interpreting ability of vEF in short period.Methods:A total of 27 multicentre emergency medicine residents were recruited and divided into conventional training group (N = 13) and video clip training group (N = 14). Self-training was done for 1 week. Pre-test and post-test comprising 20 questions were used for evaluation, and scores and interpretation time were recorded.Results:The score of the video clip training group showed a statistically significant improvement in contrast to the conventional training group (the score of pre- and post-test...
