Many successful applications of information systems have been introduced and implemented in hospitals. However, the integration of these applications into a cohesive hospital-wide information system has proved to be more complicated to develop and difficult to accomplish than expected. This paper introduces HIS/BUI, a framework for bottom-up integration of hospital information systems, and demonstrates its application through a real-life case scenario. The scope of the proposed framework is the integration of heterogeneous clinical, administrative, and financial information elements of a hospital into a unified system environment. Under the integrated architecture, all existing local applications are preserved and interconnected to an information hub that serves as a central medical and administrative data warehouse.
