This study aimed to determine whether a focused 2-day cardiac ultrasound training course could enable physicians to obtain and interpret focused cardiac ultrasound (FCU) images from critically ill patients. We retrospectively reviewed the FCU images submitted by the physicians who attended a 2-day FCU training courses. Three experienced trainers reviewed the images separately. They determined whether the images were assessable and scored the images on an 8-point scale. They also decided whether the physicians provided correct responses for visual estimations of the left ventricular ejection fraction (LVEF) and right ventricle (RV) dilatation and septal motion. Among the 327 physicians, 291 obtained images that were considered assessable (89%). The scores for parasternal short-axis view were lower than those obtained for other transthoracic echocardiographic views, p < 0.001. More physicians provided incorrect appraisals of LVEF than of RV dilatation and septal motion (19.9% vs. 3.1%, p < 0.001). The percentages of incorrect answers by LVEF category were as follows: 34.8% on images of LVEF < 30, 24.7% on images of LVEF 30–54, and 16.4% on images of LVEF ≥55%, p < 0.001. A logistic regression analysis showed that patients with abnormal LVEF were associated with physicians’ incorrect assessment of LVEF, with an odds ratio of 1.923 (95% confidence interval (CI):1.071–3.456, p = 0.029). A large proportion of physicians could obtain and interpret FCU images from critically ill patients after a 2-day training course. However, they still scored low on the parasternal short-axis view and were more likely to make an incorrect assessment of LVEF in patients with abnormal left ventricular systolic function.

经过为期2天的培训课程，医师能够从重症患者获得并解释聚焦的心脏超声图像

这项研究旨在确定为期2天的重点心脏超声培训课程是否可以使医生从危重患者中获取和解释重点心脏超声（FCU）图像。我们回顾了参加为期2天的FCU培训课程的医生提交的FCU图像。三位经验丰富的培训师分别审查了图像。他们确定图像是否可评估，并以8分制对图像评分。他们还决定医生是否为视觉估计左心室射血分数（LVEF）和右心室（RV）扩张和间隔运动提供正确的反应。在327位医生中，有291位获得了可评估的图像（89％）。胸骨旁短轴视野评分低于其他经胸超声心动图视野评分，p <0.001。相对于RV扩张和间隔运动，更多的医生对LVEF进行了错误的评估（19.9％对3.1％，p <0.001）。LVEF类别的错误答案百分比如下：LVEF <30的图像为34.8％，LVEF 30-54的图像为24.7％，LVEF≥55％的图像为16.4％，p <0.001。Logistic回归分析显示，LVEF异常的患者与医师对LVEF的错误评估有关，优势比为1.923（95％置信区间（CI）：1.071-3.456，p = 0.029）。经过为期2天的培训课程，大部分医师可以从重症患者获得并解释FCU图像。然而，
