YANBU to wonder about the risk of cross infection, though YABU to think it's because "nurses don't care". As others have said, they may be community based, and if not they may not have access to changing facilites, I work in a massive trust and the changing facilities are a joke (the tiny toilet! shared with another ward! not cleaned all that efficiently!), and the "autovalet" (shudder) is grim.
I've never used it, as students we weren't allowed (student midwife on bus probably has no access to changing facilities and has to launder her own kit) and then I never bothered since qualifying as there are never any suitable uniforms available, they only ever have size 8, which are proper oldschool 30-22-32 size 8 not the modern ones that would at least fit a few people, and they are not very clean looking! Staff nurses used to wear white and you should have seen the state of the autovaleted uniforms, grey and horrible. Bloodstains, biro, god knows what they do to them!
Also, given that I've never had access to a locker and often have had to work with my purse in my uniform pocket, you can't really blame people for not wanting to leave their own things at the mercy of whoever. Theft is sadly rife in hospitals, patients, visitors, staff, opportunists who just "sweep" a ward...
I used to wear scrubs which is better, though I am allergic to industrial detergent so still had to launder my own. Thank god I lived in rented accomodation, doing that many boil washes meant we got through a few washing machines.
Agree about managers making stupid decisions about people "looking smart", they stopped A&E nursing staff wearing scrubs here (docs still do
one rule for us etc) a few years ago which is just daft. They are much more comfortable for physical work, which is what a lot of HCPs are doing, and if the risk of contamination from uniform worn away from clinical areas is SO great, scrubs are the answer!
I do think it's unfair that nurses get so much stick when junior doctors wear their own clothes on the way to work, in the cafe at lunch, in the pub after and then come to work in the same trousers and cardigan the next day...they are "in the thick of it" too and should have to wear some sort of uniform I think.
