Should it be done? Absolutely not. Is it done? You betcha - you saw that yourself.
Technically, if the scrubs
are provided by the hospital for the staff to wear (not all are), then wearing the scrubs out of the hospital is theft. Keep in mind, not all institutions are the same. I have heard of some that require the staff to purchase and launder their own scrubs. I believe that in the operating field (OB, C-Sections, and other types of surgey), that scrubs should be provided by the hospital and laundered by the hospital. Kind of gross (and unsanitary) to get blood/bodily fluids on your person, and bring it home to wash in your own machine.
I am in the OR, and we are provided scrubs by the hospital. When I was in school, if your uniform was soiled, we were supposed to change into scrubs and allow the hospital laundry to remove the blood/bodily fluids from our uniform. I had never encountered that myself.
We have staff that wear scrubs home, but at least they change into clean scrubs after the shift. They also wear scrubs to work (I guess the pair that they wore home the night before).
I think that people wear scrubs as some type of status symbol. (Look at me!! I work in the OR!!) Or, perhaps not, maybe they just feel that it's easier to dress and change.
Floor nurses wear their unifors to and from home/work. They have to. They don't have a place to change (in most cases and places). Many of them use scrubs rather than traditional uniforms. If I were a floor nurse, I'd buy scrubs to work in. And you don't always go right home after work.
Have I rambled on enough? Sorry!!
