> we can't control for any of them Yes, we can. Infection control procedure is exactly that, and we have begin looking at how we can minimize as many of those items as possible. Things like the universal gowning and gloving studies, examining how to clean surfaces and keep them clean, what to do about cell phone and clothing contamination, etc. There are a massive number of studies showing contamination of things doctors carry, and studies showing heavy correlations between the level of contamination and patient outcomes. It's an active area of research, and commercial development. Your idea that somehow "Wash your hands and change gloves" is fine, but "Find out if you can use clorhexidine wipes on Google Glass, and if we need to" is somehow Infection Control Gone Mad! really puzzles me.
