Abstract

It has been widely recognized that one of the keys to cost reduction and service improvement in national health care lies in the integration of medical information system. Integration of information can not only improve care delivery today, but it can also help build research bases to enhance future care delivery. The question is how to achieve such integration? Imposing a single client software solution or common clinical terminology does not appear likely to happen. That lack of single software solutions and common terminologies means that solutions to integrate medical information will have to use, and somehow solve, the many heterogeneous data sources that currently exist. We believe the GRID computing paradigm has the potential to provide viable solutions to this problem. In collaboration with researchers in Health Information Science and practitioners in Health Care, we have developed a prototype for the Health Information Grid, a middleware technology that supports inexpensive mediation of medical information among rapidly evolving, heterogeneous medical information sources. This paper makes three main contributions: (1) it discusses issues and requirements arising from constructing a global health information network in Canada from a software engineering point of view, (2) it presents the concepts of a technology developed to address these issues, and (3) it presents a prototype of this technology along with a case study developed in collaboration with domain experts and practitioners.
