This paper reports the research findings in the design of an intelligent multimedia patients information systems (IMPIS). The system is aimed to be used by medical professionals at different organizational levels within a hospital, as well as hospital administrative executives for management support purposes. The data transmitted could be in the form of text, graphics such as electronic diagnostic images, sound such as voice annotation notes, or video such as critical moments during an operative procedure. These data are used for helping practitioners in the diagnostic process, conducting research in medical areas, and archiving of medical information for future references and medical legal purposes. In addition, statistical results can be generated for facilitating resources planning in hospitals. This paper presents an integrated object interface-scenario modeling approach to designing such a system. The problems found, with the illustration of a prototype, and the proposed solution to the identified problems are discussed.
