To assess the chest computed tomography (CT) imaging interpreting skills of emergency department (ED) doctors and to study the effect of a CT chest imaging interpretation lecture on these skills.
Sixty doctors in two EDs were randomized, using computerized randomization, to either attend a chest CT interpretation lecture or not to attend this lecture. Within 2 weeks of the lecture, the participants completed a questionnaire on demographic variables, anatomical knowledge, and diagnostic interpretation of 10 chest CT studies. Outcome measures included anatomical knowledge score, diagnosis score, and the combined overall score, all expressed as a percentage of correctly answered questions (0-100).
Data on 58 doctors were analyzed, of which 27 were randomized to attend the lecture. The CT interpretation lecture did not have an effect on anatomy knowledge scores (72.9 vs. 70.2%), diagnosis scores (71.2 vs. 69.2%), or overall scores (71.4 vs. 69.5%). Twenty-nine percent of doctors stated that they had a systematic approach to chest CT interpretation. Overall self-perceived competency for interpreting CT imaging (brain, chest, abdomen) was low (between 3.2 and 5.2 on a 10-point Visual Analogue Scale).
A single chest CT interpretation lecture did not improve chest CT interpretation by ED doctors. Less than one-third of doctors had a systematic approach to chest CT interpretation. A standardized systematic approach may improve interpretation skills.
评估急诊科（ED）医生的胸部计算机断层扫描（CT）影像解读技能，并研究 CT 胸部影像解读讲座对这些技能的影响。
使用计算机随机化，将两家急诊科的 60 名医生随机分为参加或不参加胸部 CT 解读讲座两组。在讲座后的 2 周内，参与者完成了一份关于人口统计学变量、解剖学知识和 10 项胸部 CT 研究的诊断解读的问卷。主要结局指标包括解剖学知识得分、诊断得分和综合总得分，均表示为正确回答问题的百分比（0-100）。
对 58 名医生的数据进行了分析，其中 27 名随机参加了讲座。CT 解读讲座对解剖学知识得分（72.9%对 70.2%）、诊断得分（71.2%对 69.2%）或总体得分（71.4%对 69.5%）均无影响。29%的医生表示他们对胸部 CT 解读有系统的方法。整体自我感知的 CT 影像解读能力（大脑、胸部、腹部）较低（10 分制视觉模拟评分在 3.2 到 5.2 之间）。
单次胸部 CT 解读讲座并未提高急诊科医生的胸部 CT 解读能力。不到三分之一的医生对胸部 CT 有系统的解读方法。标准化的系统方法可能会提高解读技能。
