Using a web-based prototype and human-computer interaction concepts to develop a vision for a next generation patient care management system.

This paper describes the novel use of two tools to develop requirements for a new generation patient care system: a web-based prototype and a human-computer interaction framework. These tools allowed a development team to crystallize new requirements for a patient care system, illustrate to clinicians a radical change in care process models, and begin the change management process in a large enterprise.
