I have a few friends that will clean their stethoscope, folder, scissors, etc with anti-bacterial wipes before they leave the floor at the end of the shift and that is great.
What I think is a little funny is wiping down their shoes, including the bottom of their shoes, with these wipes then.....you still need to walk through the hospital to get to your car, right?
I used to change my shoes when I got to my car and left my work shoes in the trunk. Lately I am lazy and drive in my work shoes and just leave them in the garage by the car. I never wear them in the house though.
Also, after I wash my hands when I am leaving the hospital, I use the paper towel I dried my hands with to open doors on my way to the garage so my hands stay clean.
