Data-oriented maintenance of clinical pathway using clustering and multidimensional scaling

Since hospital data include temporal trends of clinical symptoms and medical services, we can discover not only knowledge about temporal evolution of disease, but also one about medical practice from hospital information system, which will lead to data-oriented hospital management. This paper proposes temporal data mining process and applied the method to construction and revision of clinincal pathway by using temporal knowledge obtained from data. The results show that the reuse of stored data will give a powerful tool for maintenance and construction of clinincal pathway, which can be viewed as dataorientd management of nursing schedule.
