The drive was spurred, in part, by a notorious 2005 Pennsylvania case in which a patient nearly died because a nurse used a yellow band thinking it meant “restricted extremity” (don’t draw blood from that arm), as it did at another hospital where the nurse sometimes worked, when at this hospital it meant D.N.R.
