As part of World Hand Hygiene Day, CDC has posted a message on their Safe Healthcare Blog about what they call the “Finger Paint Method” of checking the thoroughness of hand washing. Purchase a small quantity of brightly colored finger paint from a toy or art supply store. Ask your practitioner or colleague to put on gloves, and apply a dollop of finger paint in the palm of one glove. Then ask them to close their eyes and pretend to wash their hands just as they normally would. After twenty seconds, ask them to open their eyes, and see where on the gloves there is no finger paint – those are places where microorganisms can loiter.
