Abstract

The proliferation of advanced information technology into hospitals has enhanced the development of a wide variety of applications in a hospital environment. One of the pitfalls of this trend is the fragmentation of a hospital's applications portfolio among separate, stand-alone systems in different computing environments. This usually results in a heterogeneous data base environment that limits the ability to share data among various users in a hospital. This paper describes the problem of heterogeneous data bases, discusses the need for an integrated hospital information system and provides a five-step methodology for integrating heterogeneous data bases in a hospital environment. Its goal is to provide data base integators with a systematic approach and an understanding of the issues involved for successful integration. The scope of this methodology facilitates bottom-up integration of medical, administrative, and fiscal information elements of a hospital into a unified environment.
