The use of an information system architecture modeling tool in the development of disease management systems.

Abstract

A Disease Management System (DMS) refers to an integrated healthcare delivery system that provides patient centered care throughout the course of the disease independent of delivery site. A fundamental barrier for the development, implementation and monitoring of a DMS is lack of an appreciation by care providers of the complexity of these systems, and what is required for their maintenance. Foremost in the development of these systems is the presence of information systems that attempt to deal with the temporal, spatial and information needs of the DMS. The Zachman Framework for Information Systems Architecture is used in many industries in the development of information systems. Its choice is based on the recognition of a need for a methodology in the conceptualization and modeling of complex information systems. This paper provides a brief overview of the Zachman Framework and its potential application in DMS development. In particular it will be the focus on the need for "perspective" clarification as the first step in the development of such complex systems. This paper reviews DMS and their potential information needs. The clarification of "perspectives" provides a method toward team building and unification of purpose by decreasing conflict and recognizing the unique contributions that each perspective holder makes.
