Then let the New England Journal of Medicine explain it for you! Didier Pittet and colleagues have put together an instructional video on hand hygiene--many of you have probably seen it already, but if you haven't, take a look.
One concern is whether anyone will have the stamina to stick with the video for the full 15 minutes, but the player allows you to click around to a topic of interest if your attention begins to wane. Also, it might have been more effective with a human voice (if it is a human voice, my sincere apologies to that person--but it sounds robotic or synthetic). On second thought, robots may be just what we need on the units: robotic hand hygiene observers who confront healthcare workers on their way out of the room with a detailed assessment of their HH performance!
