as for shammans - not a chance I would send a patient your way for the exact reasons outlined above.
Your differential would include impacted soul, chicken bone rattling deficiency, and physic energy deterioration
Your treatment would include soul retrieval, chanting and focusing energy
Your outcome would include a dead patient form adrenal failure and ensuing shock.
So it would be incredibly dangerous to send anything to a "shamman" that had a need for medical treatment. I wouldn't even send the psychiatric patients because I am not that mean and they deserve better (like medication)
So sorry shamman - I don't see a place for you in a traditional western medicine where goat skin chaps and glowy hands are left at the door
