Abstract
A series of computer software tools have been developed which can help to discover clinical problems, and to develop diagnostic and management hypotheses based on relevant information in the medical literature. These tools are: the Problem-Know ledge Coupler, the Coupler Editor, the Knowledge Network, and the computerized Problem-Oriented Medical Record. In this paper the Problem Knowledge Coupler will be described as it works for a typical office encounter to investigate a patient's presenting complaint, and then as it works for compiling history and physical examination data. The Coupler Editor and the-Knowledge Network will be described in terms of their use in building Knowledge Couplers. Finally, the microcomputer version of the Problem-Oriented Medical Record will be illustrated as it is used to organize and record Coupler-based diagnostic and management decisions.
