| Research Abstract |
The purpose of this research is to establish a method of extracting prediction rules on outbreak of hospital-acquired diseases from medical test data-base which are stored in hospitals, and to construct a decision support system for preventing hospital-acquired diseases. We have performed the research by setting the following sub-themes :
(1)Establishing a method of extracting rules from medical test data-bases.
(2)Construction of a decision support system for preventing hospital-acquired diseases
For the former, we investigated two methods to extract rules of the style "if_then_else" based on the data-mining approach, one is the decision tree construction and the other is the association rule extraction. Especially, we discussed the prediction rules concerning to MRSA which is serious in present hospital-acquired infection. Furthermore, it is important for making clear the relation between medical treatment and hospital-acquired infection to analyze the characteristics such as the change

of drug resistance. From this viewpoint, we have also discussed the sequential pattern mining. We used the medical test data which are stored in a certain hospital from 1994 to 1999 (8MB) as the object data. Medical staffs examined the obtained results and evaluated that some valuable rules are included though the majority were predictable ones.
For the latter, we investigated the construction of decision support system for preventing hospital-acquired diseases for persons engaging to medical institutions from the data warehouse viewpoint. We have developed the system in the server & client style by using JAVA language to use it in the network environment. The developed system consists of the rule extraction tool and the rule examination tool. The rule extraction tool works under SQL circumstance. The rule examination rule has the function to judge the significance of any given rules, and to display the analyzed statistical data in the forms of graphs or tables so that medical staffs can understand the situation.
