Not to mention increased resistance from bacteria

And of course the needed contact with foreign agents to build immune resistance. Use antibacterial soap when needed: hospitals

Is there any evidence for this? Generally speaking, one would expect biocide resistant bacteria to be less antibiotic resistant.

Well the problem is that a lot of antibiotic resistance can be attributed to efflux pumps that literally pump the stuff out of the bacteria. So these are generalized resistance mechanisms that target a broad array of environmental stuff that might ordinarily kill a microbe. Here's a pretty well-cited paper on the issue, though it's rather old: http://aac.asm.org/content/45/2/428.short

Biocide resistance is also a problem

I'm not sure if there's a relation of resistance between biocides and antibiotics

I'm not a biologist, but I would assume that bactericides for external use can be much more aggressive than antibiotics that are injected in the organism; they are expected not to kill the patient altogether the bacteria.
