The fundamental idea of error-proofing is to make errors impossible. I
while back in a creativity session focused on improving adherence to
hand hygiene cleanser use, I jokingly suggested that automatic door
openers be activated
only by the use of a hand sanitizer dispenser.
This was in the wake of SARS in Toronto, so hand-hygiene stations at
all hospital entrances were the new thing. The safety concept deployed
in this idea is that of a forcing function - the next step
(entry to room) cannot be performed until a necessary safety precaution
is followed. The idea brought howls of laughter, always a cue that an
idea is either too wacky to be considered or on a new track to
innovation. That was about 5 years ago.
Well, someone has done it.
