I wonder if there would be a role for someone specialized in diagnosis/triage? I'm a martial artist, so it's not uncommon for me to go to the Dr. when all I really need to know is if an injury is a normal "take a break and let it heal" injury or one that needs actual treatment. I imagine there's similar cases for questions like "is this the common cold or something else?" or "is this something babies just do or a sign of a problem?".
