You seem to be afraid to exercise professional judgement in this situation
Part of the problem is liability, either perceived or real. The other part is that the average internist or FP has zero, I mean zero training in aviation medicine. The point about the pediatrician signing sports PE forms is amusing because, well, she/we are trained in sports pe/concussion protocol/return to play etc. She opines that she would have no problem signing a basic med form, but, she doesn't in fact, sign these for a living. But she thinks someone else should, "no problem..."
To beat a dead horse a bit, signing form 8700 suggests we are following some medical criteria for fitness to fly. "Professional judgement as you call it." But the average internist or GP gets NO training in aviation specific medicine and congress did not see fit to define fitness, save for the conditions that can exclude you or require an SI. They can't really exercise any professional judgement in the absence of criteria...
There is a trend now for docs to get away from signing scuba, DOT, basic med, disability, etc etc. For most of these, there are docs trained in these areas, i.e. dive medicine, DOT, disability, and um, maybe for aviation, um, AME's...ahem... Yes, yes, congress wanted to get away from the FAA and AME's. But they provided no medical guidance when they cooked up basic med.
You guys have no idea the volume of forms that come our way. Forms purely designed to transfer legal liability. Not that long ago, I had an older patient bring me a form from a health club, basically asking me as their doctor to certify, "in my professional judgement," the patient is safe to exercise and they are to be released from any medical liability should the said patient keel over and die.
Well, I hate to break it to you all, but everyone here, especially everyone over 50, even if "apparently healthy," has some nonzero chance of having a sudden cardiovascular event at the onset of regular exercise, especially if they were previously sedentary. Am I going to sign this form? This form isn't any sort of medically necessary form. It's a form developed by the lawyers of the health club to help shield or share blame. It offers no meaningful medical purpose...
Yea, most docs hate forms...
