Chlohexidine bathing to reduce catheter-related blood stream infections

hi. our unit is part of a study of the effectiveness of CHG bath in decreasing hospital-acquired bloodstream infections. we started using it 5 to 6 months ago. since it's still on implementation phase, we don't know its effectivity yet but so far i like it because it's easy and quick to use.

Wash basins are also being implicated as they serve as a reservior for bacteria especially if they are stored so that moisture is left after use.

While we have no protocol for using Chlorhexidine baths yet in our unit, I have suggested it to a member of the Infection Prevention team. I suppose my main concern over making chlorhexidine baths standard practice would be the risk of CHG resistant bacteria. Anyone else share this concern? I suppose that eventually any antiseptic is going to go the way of Triclosan, but the longer CHG could work the better...considering we use it for nearly everything.
