Not much of a poker player (though my sons are quite good at it). Just saw it posted on Red State Moron and thought you guys might be interested. I don't think the question has been answered conclusively yet. Have seen other studies that question the connection but don't have time to find them right now.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
