Last month in JAMA, Mark Sklansky and colleagues wrote a Viewpoint column, “Banning the Handshake From the Health Care Setting.” The article explored the idea and its feasibility, while acknowledging the importance of such rituals as handshakes in human interaction. In the end, the authors argued that it’s an idea we might need to start taking more seriously.
Is this an antisocial idea? That’s debatable, but it would certainly be a good step towards reducing transmission of infections—and one that’s probably long overdue.
It’s well known that pathogens are easily transmissible from health care workers’ hands, even if they practice hand hygiene in between seeing patients. But as the authors remind us, heath care workers are notoriously bad at doing so—they cite research showing that “compliance of health care personnel with hand hygiene programs averages 40%.”
And it’s no better in ambulatory care settings—an original research article we published in March 2013 that measured hand hygiene compliance by health care workers in an ambulatory care clinic found that, even after a campaign to improve adherence, compliance (as measured by direct observation) had only improved to between 32% and 51% at one-month follow-up. The introduction of alcohol-based hand sanitizers helped, but they aren’t effective against all pathogens, including C. difficile and some noroviruses
Bacteria have been shown to live on many surfaces—computer keyboards, telephones, uniforms, and even paper (see our December 2011 research article, “Survival of Bacterial Pathogens on Paper and Bacterial Retrieval from Paper to Hands”). If a conscientious nurse charted on a paper chart or entered a patient’s vital signs into the electronic record after providing care but before washing hands, bacteria could be transmitted to whoever next picked up the chart or used the keyboard. Then that person might shake hands with a family member or colleague, and so on, and so on . . .
