Proteus Intelligent Processes is a set of tools based upon the Proteus model and the GreEd rule authoring system. Proteus (PROcesses and Transactions Editable by USers) is a software technology that allows creating clinical processes in which clinical intelligence is embedded. These processes can then be executed to provide guidance to the clinicians about individual patients. The main advantage of Proteus is that the processes can be edited even by non-programmers, with the use of appropriate tools. The processes and components can be stored in a library and can be reused to create other processes. GreEd is the foundation of a full-fledged business rules management system (BRMS). Ease of editing is its key strength. These tools are linked with electronic medical record systems and clinical information systems.
