How bad is the isolation problem where you work?

We have quite a few people on MRSA and VRE isolation on the floor, and while i see the CNAs and the nurses wearing everything to go in the room, quite a few DOCTORS aren't putting ANY PPE on when they go in the room. Touch the pt., their covers, bare handed, then not even stopping to wash their hands or a even a squirt of Purell, and less than 15 seconds later going into a surgical pt.'s room! Yet the nursing staff is preached at and threatened with written warnings if they don't.

I've wrote my concerns down (weird how some new MRSA cases popped up in the past few days, that have the same Dr.'s name in common) and i'm working on a letter to the VP and Infection Control. But how bad of a problem is it where you work that staff isn't complying with it? And what's your policy concerning it?
