Over the last few years, AORN and the American College of Surgeons have been battling it out over AORN’s 2014 guideline that has increasingly led to the banning of the surgical skull cap in the operating room in favor of the bouffant cap as the preferred surgical headgear. Lacking from this kerfuffle has been much in the way of evidence to support AORN’s guideline, but unfortunately that didn’t stop the ACS from appealing mainly to tradition and emotion in objecting to it.
