Unfortunately, it seems to be a catch-22. If you don't involve doctors in the design, you'll end up with something that doesn't cover enough ground to be usable, if you do involve them, they'll mistake their (admittedly large) domain expertise in medicine for expertise in system design and bike-shed the thing into boondoggle territory. Any standard is going to be a tough proposition.
