User metaphors for health care professional workstations.
The problem encountered by health care professionals and software developers has been a lack of demonstrable visions (prototypes) for Computer-based Patient Record (CPR) and Clinical Information System (CIS) applications. This deficiency has resulted in a quest for and consideration of models, metaphors, and mind maps for the Healthcare Professional Workstation (HPW)--the access mechanism for the CPR and the CIS. The familiar physician desktop and traditional paper-based metaphors are not adequate for all aspects of clinical information processes. In the clinical care environment, the flowsheet is a transporting metaphor because many different applications and tasks can be 'transported' into the flowsheet. 3D Rooms, Gopher and Genes are familiar and transporting metaphors to be exploited for HPWs. Using transporting metaphors for HPW software emphasizes commonality and de-emphasizes diversity. Each model and metaphor has an associated mind map. Only the mental model, mental metaphor or mind map for HPW software is important. Metaphors communicate real-world analogies, and communication is at the core of what defines usability. A mind map facilitates communication by building a model in the user's mind. The barriers to HPWs are not technical; they are related to economics, ownership of patient information, liability and information standards.
