She says she finds such a position odd, considering that so many AAFP members "work in practices that depend very heavily on nurse practitioners to provide primary care."
Personal anecdote time: I've been going to the same primary care practice for many years, and I have seen the supervising physician exactly once. I have never felt like my healthcare was compromised. My three-year-old daughter, who has several complex medical issues, most often sees an NP for her primary care visits.
When something has been outside their scope of expertise, every one of them—without hesitation—has referred my daughter or me to the proper specialist. Of course they do. That's the function of primary care.
So, why would the AAFP suggest otherwise? I wouldn't expect my primary care physician or the PA that I usually (and prefer) to see to perform surgery, and I trust any member of our care team to make appropriate referrals.
