This is the first full-production system built for the Northwestern University Medical School. Students are in the role of a general practitioner who needs to diagnose and suggest treatments for three different pregnant women who are having nutrition-related difficulties.
Students meet the doctor for whom they are working on these cases and then meet their first patient, a pregnant teenager who feels frequently ill and is a vegetarian. Students can interrogate her about her diet and eating habits or run 7 diagnostic tests looking for diabetes, anemia, and other signs of metabolic mishap.
Students can choose from a wide variety of claims about their patients, from iron deficiencies to being overweight. They can entertain these claims simultaneously (different from the systems described above which only allow one claim to be supported at a time).
For each claim, students drag in information to support the claim from their notebook of interview notes and test results. They then identify what problems the patient will develop if their nutritional condition is not rectified by selecting them from a list of possible risks and dragging them into a different supporting evidence notebook.
Students then suggest basic treatments by selecting from a static list of treatments. These treatments range from eating more green vegetables to removing large amounts of caffeine from their diet. The students' client (the consulting physician) leaves a series of notes on the students' charts, catching mistakes and suggesting solutions. Once the student has successfully identified and supported all of the relevant claims (or ``concerns'') for this patient, they see a wrap-up video of the patient and move on to the next one. There are three patients in all.
This project will be deployed in 1998 as part of a new nutrition unit that 2nd year medical students at NUMS will experience.
