As a physician caring for a patient whose problem is undiagnosed
I want to know what additional data I will need
so that I can arrive at the most likely diagnosis with the least possible cost (in terms of time, money, patient discomfort, etc).

Possible approach:

• capture the relevant data that is already known
• link known data to possible problems
• elicit a list of data points which may confirm or exclude the possible problems

Acceptance criteria:

• prioritize list of needed data according to diagnostic value vs cost
