yep, as has been previously mentioned, anyone with MRSA goes on contact precautions, gloves, mask, gown. what i dont understand is why ANYONE, let alone a nurse that has to go and deal with another patient, would want to even touch someone with MRSA without gloves. That's asking for trouble...i dont care how good your handwashing technique might be, its just not good care.
As also previously mentioned, i dont know about your hospital, but our patient care director (aka nurse manager) makes the rounds in each room, talking to the family, making sure everything is up to par. This would be a great opportunity to bring it up, without having to mention names (if you dont feel like, that is). If he/she doesnt make rounds, then just go looking for that person. Its obviously a unit-wide problem that needs to be addressed, so that would be the first person i would contact.
if no one listens, your next contact should be the infectious disease dept.
