I'm on the editorial panel of a set of guidelines for rational use of diagnostic imaging:
http://imagingpathways.health.wa.gov.au/ It is quite algorithmic in style and I feel that sometimes in "grey areas" it offers apparently black-and-white advice on whether to image or not. I wonder if in some of these cases we might more explicitly suggest clinicians discuss the low probability of meaningful yield from investigating, and tailor the decision to the patient's own values. I wonder, if we decide to try to do that, how it might best be done. Any examples or suggestions would be welcome.
