| Outline of Final Research Achievements |
We aimed to obtain reliability of disease name from data of hospital information system.
For the definite disease name of the hospital information system, the proportion of examination, prescription and treatment being conducted in the case group and the control group was obtained, the item with the large value was selected, and the rule was obtained by the decision tree model. In addition, it was possible to identify the true disease name by finding the ratio of what kind of item taken in the model to the name of disease and classifying it by the cluster method as the characteristic quantity characterizing the item . Moreover, we applied the obtained rule to the verification data and found that some degree of accuracy can be obtained only with the order entry data. To use the narrative part of the electronic medical record as information, it turned out that applying a latent topic model is effective.
