Having just returned from SMACC, I've been thinking of all of the wonderful people with whom I got to interact. Always a delight is the inestimable Vic Brazil. I remember her gently mocking the EMCrit site for its absence of a single article on handwashing. While this is merely tangential, a search of the site for “handwashing” will now bring up this post saving me from any further shame:
Reducing pathogen transmission in a hospital setting. Handshake verses fist bump: a pilot study
Ghareeb PA1, Bourlai T, Dutton W, McClellan WT.
J Hosp Infect. 2013 Dec;85(4):321-3. doi: 10.1016/j.jhin.2013.08.010.
Handshaking is a known vector for bacterial transmission between individuals. Handwashing has become a major initiative throughout healthcare systems to reduce transmission rates, but as many as 80% of individuals retain some disease-causing bacteria after washing. The fist bump is an alternative to the handshake that has become popular. We have determined that implementing the fist bump in the healthcare setting may further reduce bacterial transmission between healthcare providers by reducing contact time and total surface area exposed when compared with the standard handshake.

Has it always struck you as silly to mandate hand-washing prior to putting on gloves for simple exams? Well, your intuition is quite correct it seems:
Here is a viewpoint on handshakes in the healthcare setting
Is hand hygiene before putting on nonsterile gloves in the intensive care unit a waste of health care worker time?–a randomized controlled trial.
Hand hygiene (HH) is recognized as a basic effective measure in prevention of nosocomial infections. However, the importance of HH before donning nonsterile gloves is unknown, and few published studies address this issue. Despite the lack of evidence, the World Health Organization and other leading bodies recommend this practice. The aim of this study was to assess the utility of HH before donning nonsterile gloves prior to patient contact.
A prospective, randomized, controlled trial of health care workers entering Contact Isolation rooms in intensive care units was performed. Baseline finger and palm prints were made from dominant hands onto agar plates. Health care workers were then randomized to directly don nonsterile gloves or perform HH and then don nonsterile gloves. Postgloving finger and palm prints were then made from the gloved hands. Plates were incubated and colony-forming units (CFU) of bacteria were counted.
Total bacterial colony counts of gloved hands did not differ between the 2 groups (6.9 vs 8.1 CFU, respectively, P = .52). Staphylococcus aureus was identified from gloves (once in “hand hygiene prior to gloving” group, twice in “direct gloving” group). All other organisms were expected commensal flora.
HH before donning nonsterile gloves does not decrease already low bacterial counts on gloves. The utility of HH before donning nonsterile gloves may be unnecessary.
