Beeps and blinking lights are the constant chatter of a hospital intensive care unit, but at the I.C.U.’s in North Shore University Hospital in Manhasset, N.Y., the conversation has some unusual contributors. Two L.E.D. displays adorn the wall across from each nurses’ station. They show the hand hygiene rate achieved: last Friday in the surgical I.C.U., the weekly rate was 85 percent and the current shift had a rate of 91 percent. “Great Shift!!” the sign said. At the medical I.C.U. next door, the weekly rate was 81 percent, and the current shift 82 percent.
