I would say the logical thing to do for the doctor is Not to trust the patient peer until AFTER the doctor has actually read the article himself. The problem here is the doctor will likely trust the patient without ever reading the article.
There has to be some degree of verification regardless of how complex the world is. At the very least he should read the paper. Because not doing so is hypocritical. Doctors treat patients as dimwitted idiots but suddenly the patient is smart because he has a paper? No, you can't make that judgement unless you read the paper.
