player
n.— «Some patients are referred to as “players,” I know not why. You might “inherit” a “dialysis player” at signout—that is, come to a shift and take over the care of a patient who is on chronic hemodialysis.» —“Doctors’ Lingo That Leaves You Speechless” by Jenny Blair Hartford Courant (Connecticut) May 28, 2006.
