It’s an intriguing idea: doctors going “bare below the elbows” to prevent the spread of infections. The United Kingdom’s Department of Health has adopted this policy, which bans the wearing of neckties, long sleeves, lab coats and jewelry – deemed “functionless clothing items” – because they can be colonized by pathogens.

Infection control societies in the U.S., on the other hand, don’t recommend similar dress restrictions because there is no strong evidence that healthcare workers who don’t wear ties or jewelry reduce the risk of infection. One infectious disease expert from Emory University said doctors or nurses who don’t adequately wash their hands pose a far greater risk to patients. In fact, hand washing is one of the best ways to combat infections, both in the hospital and in your own household.

However, some U.S.-based physicians are considering going tie-less and jewelry-free as just one more way to promote better overall infection control. So don’t be surprised if you see your doctor making rounds in a polo shirt. He or she has left the “functionless clothing items” at home.
