New Guidelines For Healthcare Personnel Attire Are Short On Evidence
The Society for Healthcare Epidemiology of America (SHEA) guidelines for healthcare workers attire have just been published.
Science Daily  led with the headline "New Infection Control Recommendations Could Make White Coats Obsolete," which is rather misleading since the guidelines say no such thing.
I won't reproduce the entire 15-page document here since the full text  is available online. But here are some highlights along with my comments.
The guidelines say that facilities may consider adopting a "bare below the elbows" (short sleeves, no watch, no jewelry, no ties) policy. They concede that the incremental infection prevention impact of a BBE approach to inpatient care is unknown but it is probably not harmful. I recently wrote  about some comments from a microbiologist in the UK on the possible disadvantages of the BBE mandate already ongoing there.
Despite the Science Daily headline, the guidelines actually say that white coats are acceptable as long as they are removed before contact with patients and are laundered regularly. What constitutes "regularly"? The guideline says In our opinion, white coats worn during patient care should be laundered no less frequently than once a week and when visibly soiled. They discuss the debate about whether patients prefer to see doctors in white coats. I blogged  about this a while ago too.
They stayed on the fence about whether clothing worn in the hospital should be laundered professionally or at home and surprisingly, did not recommend prohibiting the wearing of neckties.
The Science Daily story contained some interesting quotes from one of the authors of the guidelines.
