Outline of Final Research Achievements

We constructed the classification methods for patient data in hospital information system combined with order information and text information which is processed by latent topic model in order to obtain the characteristics for patient in each cluster. The classification results show that it is easy to explain the background of each patient based on the feature of input text information.

Academic Significance and Societal Importance of the Research Achievements

本研究により、病院情報システムに蓄積されているテキストデータを適切に利用し、検査オーダ情報などの構造化データと組み合わせることで、これまでより精度よく解析が行うことが可能となった。また、医師の意図を反映させた解析を行うことが可能となった。このことにより、病院情報システムデータに対する解析がより進捗し、知見も得られやすくなり、患者への医学的な知見を反映させやすくなったと考える。
