Outline of Final Research Achievements

In this study, we conducted emotion analyses with biometric data using a wearable device on initial clinical residents. It was found that the emotional factors varied depending on the time of day and the period of observation.
Regarding the relationship between emotions and the occurrence of human errors, the self-administered survey revealed that the emotional factors such as impatience and overstress were observed before the occurrence of errors. However, the emotion analysis did not reveal any differences between the before and after errors. Since there was some bias in the content of the errors recorded in this study, it is necessary to accumulate data on various types of errors and examine them in more detail in the future.

Academic Significance and Societal Importance of the Research Achievements

疲労やストレス、感情などの心身の状態はヒューマンエラーの要因となることが指摘されているが、客観的に検証することは非常に困難である。本研究では、ウェアラブルデバイスを用いた生体データによる感情分析と自記式調査を併用し、初期臨床研修医の勤務中の感情因子とヒューマンエラーの発生状況を分析した。今後、対象者および観察期間を広げ、様々な状況下のデータを蓄積することで、将来の医療安全対策における新たな指標となる可能性がある。
