Shaking hands seems completely speciality dependent. In EM, when a trauma rolls in, the last thing on anyone's mind is smiling and shaking hands.
But I don't view shaking hands as vital even in non-emergent specialities; for example, in FP, I know my MD shook hands w/ me the first time she met me and never again--its more of a formality of introduction thing. I know many specialists are the same way--only shaking hands with 1st time patients. To me, it just doesn't seem like the hand-shaking dilemma comes up over and over again in a given day--maybe as an FP you'll see a handful of new patients in a day thus you won't be thinking about avoiding hand shakes all day long since most patients are regulars anyway.
