Reminders of To-Do’s-II: Workflow Agents for Reengineering Health Care Enterprises

Barry Silverman and Christo Andoyadis

This paper describes efforts to develop and field an adaptive health planner and parallel agents that securely connect distributed users and data sets in a collaborative approach able to anticipate health ToDo items and to remind and alert about these items over the web. The planner and agents, reasoning temporally and non-monotonically, are able to handle changing health conditions, unknown health facts, user wellness and lifestyle preferences, and updates about each user’s situations. A set of robust, open standards-based client server approaches (e.g., CORBA, ODBC, Java, and ANSI HL7 Common Object Model) are used to encapsulate and plug all these components into the web, and to handle the distributed agent and object communications. Extensions to these emerging standards are at times made due to engineering and domain considerations, however, the goal is to maximize reuse of published guidelines and integration of R2Do2 by any patient record system that also adheres to the standards. From this perspective, R2Do2 is an experiment in an open standards framework for middleware in the healthcare field. This research also tries to reflect lessons learned about the extensions needed in these standards if healthcare middleware frameworks are to transparently support users over the web.
