My former SIL is a ANP. She oversaw my mother's care. No concerns.
Frankly I see Nurse Practitioners as a valuable health care providers. Nurse Practitioners are particularly valuable for healthy Mom prenatal care, well-baby care, elderly care, and routine health care. These services have the highest return for the standard measures of a healthy society.
My SIL said that she had an Internal Medicine MD tell her that the best return for our health care system and the professional is a Nurse Practitioner practice. While some might not have confidence that an NP wouldn't referr when appropriate, there is little difference IMHO between them and other health care providers.
