-
摘要:
目的 评估应用标准化甲状腺结节超声培训-考核系统的短期教学效果。 方法 2017年12月, 面向北京协和医院超声医学科培训学员, 先采用标准化甲状腺结节超声培训-考核系统中的考核系统对学员进行考核, 考察内容为甲状腺结节超声特征识别及恶性风险分级, 然后采用该系统的培训部分对其进行相应培训, 培训后12 h和1个月分别再次采用该系统对所有学员进行考核, 系统自动记录考核得分情况, 比较培训前后得分差异。 结果 共12名学员进入本研究, 既往均接受过甲状腺疾病超声诊断的专业培训。在接受甲状腺结节超声培训后12 h及1个月, 学员考核成绩均较培训前显著提高[(80.7±7.3)分比(69.9±4.0)分, P < 0.01;(78.0±9.2)分比(69.9±4.0)分, P < 0.05], 且培训后12 h甲状腺结节各项超声特征及分级的诊断得分均较培训前显著提高(P < 0.05)。与培训后12 h相比, 培训后1个月学员考核成绩未明显下降(P > 0.05)。 结论 标准化甲状腺结节超声培训-考核系统可在短期内提高学员甲状腺结节超声诊断能力, 为推动甲状腺结节超声诊断的规范化教学提供了新思路。 Abstract:Objective The purpose of this study was to explore the value of short-term training in the standardized training and examining system of thyroid nodule ultrasound. Methods We prospectively recruited trainees who were trained in the Department of Ultrasound, Peking Union Medical College Hospital in December 2017, and then assessed using the standardized training and examining system of thyroid nodule ultrasound. The ultrasonic characteristics and malignant risk classification of thyroid nodules were investigated. The scores were automatically recorded by the system. The training part of the system was then used for corresponding training. After twelve hours and one month, the system was used again to evaluate all participants, and the differences in scores before and after training were compared. Results A total of 12 participants were enrolled in this study, and all had received professional training in the ultrasonic diagnosis of thyroid diseases. The results of thyroid nodule reading were significantly improved after 12 hours and one month(80.7±7.3 vs. 69.9±4.0, P < 0.01;78.0±9.2 vs. 69.9±4.0, P < 0.05). The diagnostic ability of recognition of ultrasonic features and thyroid node classification was improved (P < 0.05). Compared with the results 12 hours after training, the diagnostic level of thyroid nodule ultrasound did not drop significantly one month later (P> 0.05). Conclusions The standardized training and examining system of thyroid nodule ultrasound can improve trainees' ability to diagnose thyroid nodules with ultrasound in a short time, and at the same time, it provides new teaching methods for the standardization process of thyroid ultrasound in the future. -
