We have proposed a new type of Hospital Information System (HIS) which can be utilized as an effective system of collecting and storing data in a suitable way for various kinds of medical process analyses. In this new system, data are extracted from HIS at the time of medical act order entry, and stored in the form of “medical process tag,” which has information terms of “Who”, “to Whom”, “Where”, “When”, “Why”, “What”, “How” (6W1H) with link information to detailed data. The term “Why” is linked to other 5W1H terms by selecting a purpose before making medical act order entry. Each medical process tag is stored as one record, and all medical process tags for all patients and all kinds of processes are stored in a single table. In this way, retrieval of necessary data for various analyses of medical processes involving many kinds of medical act orders from a large amount of data can be performed efficiently and flexible. “Medical process management system” based on this idea has been implemented as a part of new integrated medical information system at Kochi University Hospital since 2002.
