This paper describes the implementation methodology of our intelligent progress note system, which is designed to support physicians in writing problem-oriented progress notes. Due to the popularity of graphical user interface, hypermedia, and the new multimedia PCs, we are currently developing our system on PCs in Microsoft Windows 3.1 by using Spinnaker Plus. The conversion of the system from a PC base to Macintosh or OS2 has proven to be easy. Our design applies cognitive models of memory as well as hypermedia to provide a creative and productive environment for the physician. The basis of our work is observation of practicing physicians writing progress notes in today's paper-driven world. Our hope is to simulate some of the more routine parts of the thinking processes that physicians devote to producing the progress note, to save time, and to provide useful reminders, so the users can concentrate on the more complex parts of the task.
