| Outline of Final Research Achievements |
This project proposes automated construction of clinical pathways from the service logs stored in a hospital information system (HIS) in the following five steps. First, service logs and discharge summaries are extracted from HIS. Then, EM clustering applies all the cases with the same DPC code and decomposes them into subgroups. Third, to each subgroup, construction of clinical pathways based on dual clustering is applied. Fourth, classifiers are constructed by using combination of correspondence analysis and classification learning methods, such as decision tree, random forest, SVM and neural networks. Then,finally classifiers and clinical pathways are linked together,The proposed method was evaluated on HIS in Shimane University Hospital, whose results show that the proposed method generate more accuratebclinical pathways.
