Unless, of course, you want to be accused of spreading rumors, hearsay, and innuendo. Remember, we are talking about an independent practitioner, not a hospital employee.
Overall, it’s a bit of a sticky wicket. If you think the complaint has merit, then it should be sent to peer review—and you may speak no more of it. If you think the complaint is baseless, then why sustain it and tell the PCP?
Peer review is an exceptional process, and the physicians who serve on such committees perform a difficult and selfless service. We should all do our best to uphold its integrity.
