Touching your face is a common behavior and it can be difficult to realize it is happening. By touching your face you can be exposing yourself to contaminants from your surroundings and/or exposing your patients to illness if you are not well.
” A behavioral observation study was undertaken involving medical students at the University of New South Wales. Their face-touching behavior was observed via videotape recording… On average, each of the 26 observed students touched their face 23 times per hour. Of all face touches, 44% (1,024/2,346) involved contact with a mucous membrane, whereas 56% (1,322/2,346) of contacts involved nonmucosal areas..”
Becoming aware of the behavior is the first step and being conscious of your aseptic techniques while doing IVs is especially important.
