Construction of Outpatient Clinical Pathway from Order Histories

Abstract

Hospital information system starts from introduction of order-entry system and has been developed into the system storing almost all information about clinical actions, where users can browse them through the window system. The most important characteristics is that each stored event is linked with time stamp, which can be used for temporal data mining to extract useful information about hospital managemnt. In this paper, we focus on waiting time that is defined as the difference between reservation and actual inspection by doctors, and attributes related with waiting time. The results shows that groups of doctors, reservation time and divisions contributes to the length of waiting time.
