UML Diagrams for the Process of Care
In this chapter, we introduce Unified Modeling Language (UML) diagrams as a means of representing health care processes. To facilitate the analysis of health care systems, health services researchers increasingly employ diagrammatic descriptions of a system’s operations. Such diagrams assist researchers in analyzing complex systems in terms of their components and functionalities, as well as the interactions among components. In the context of health care evaluation, diagrammatic description is useful in two ways: first, as a tool for documenting existing policies, which will ensure a common understanding that can eventually help to identify areas for improvement, and, second, as a tool for developing specifications for the computer simulation models needed to evaluate the policies. This chapter presents examples of use case diagrams for the activities involved in surgical care, activity diagrams for the flow of patients through care activities, and sequence diagrams for the interactions of patients and care activities arranged in a time sequence.
