The expertise of medicians in clinical decision-making is very important since it improves the quality of medical services provided to patients. This study analyzed the characteristics of the decision-making process and confirmed clinicians' electroencephalography (EEG) characteristics by measuring their cerebral activity during clinical decision-making. This study aims to present learning directions for brain-based clinical decision-making to develop medical experts.
This study was performed in the following two projects: (1) a qualitative study of clinical decision-making in a clinical scenario and (2) an analysis of differences in cortical activity of experts and novices through EEG.
In the 1st study, this study found that "confirmation of the patient's chief complaints," "physical examination," and "radiography reading" steps, which showed the most prominent differences in the experts' and novices' decision making, were set as the significant steps of dentists' clinical decision making. In the 2nd study, the experts' and novices' cortical activities were measured through a 32-channel EEG. In task 6, which had the lowest accuracy of diagnoses made by the experts, the brain activities in both groups were higher than in other tasks.
This study developed and suggested a model of the decision-making process for experts and novices and suggested the basic directions for brain-based learning needed to raise experts based on brain activity.
医生在临床决策中的专业知识非常重要，因为它可以提高为患者提供的医疗服务质量。本研究通过测量临床决策过程中大脑的活动，分析决策过程的特征，并证实临床医生的脑电图（EEG）特征。本研究旨在为基于大脑的临床决策提供学习方向，以培养医学专家。
本研究分两个项目进行：（1）在临床场景中进行临床决策的定性研究，（2）通过脑电图分析专家和新手的皮质活动差异。
在第 1 项研究中，本研究发现，在专家和新手决策中差异最明显的步骤是“确认患者的主要主诉”、“体检”和“阅读 X 光片”，这些步骤被确定为牙医临床决策的重要步骤。在第 2 项研究中，通过 32 通道脑电图测量了专家和新手的皮质活动。在专家诊断准确率最低的任务 6 中，两组的大脑活动都高于其他任务。
本研究开发并提出了专家和新手决策过程的模型，并根据大脑活动提出了培养专家所需的基于大脑的学习的基本方向。
