Good news for chilly doctors—you can wear long sleeves with impunity inside hospitals. Because University of Colorado researchers find that docs pick up just as much bacteria when their forearms are bare as they do when wearing long sleeves. The study is in the Journal of Hospital Medicine. [M. Burden et al., Cleaned Physician Uniforms and Infrequently Washed White Coats Have Similar Rates of Bacterial Contamination After an Eight-Hour Workday: A Randomized Controlled Trial]


Britain recently issued guidelines that banned white coats and long sleeves in hospitals in the hope that the move would decrease the chances of picking up and transferring bacteria, especially the scourge of MRSA: methicillin-resistant staph. The research team wanted to see if the rule would actually help. They had 50 doctors start a workday wearing a freshly washed short-sleeve shirt and another 50 in their unwashed long-sleeved white coats.


Samples were taken from all 100 docs, at the wrists, pockets and cuffs, if they had them. And by the end of an eight-hour shift, both groups of physicians were carrying similar bacteria loads. In fact, after just three hours the short-sleeved docs were already hosting half of the bacteria as the docs wearing unwashed coats. So go ahead and wear long sleeves in the hospital. If you’re going to wash something, make it your hands.

医院里有些医生不得不穿短袖冻得瑟瑟发抖,现在他们迎来了一个好消息,那就是终于可以有恃无恐地穿上长袖了~科罗拉多大学(University of Colorado)的研究人员发现,无论是光着胳膊还是身穿长袖,医生沾染到的细菌都是一样多的。该研究发表在《医院医学杂志》(Journal of Hospital Medicine)上。


英国曾发布禁止医生在医院穿白大褂和长袖外套的行为准则,希望能借此减少细菌接触和传播的概率,尤其是一大祸害MRSA:耐甲氧西林金黄色葡萄球菌(methicillin-resistant staph)。研究团队想知道这条守则是否真的有帮助,他们找来50位医生,一上班就穿着洗干净的短袖衬衫;以及另外50位医生,穿着没有洗过的长袖白大褂。

 

研究人员随后在100位医生身上都做了取样,取样位置包括腕部、口袋和袖口(如果衣服上有的话)。在8小时轮班结束之后,两组医生身上携带了几乎相同数量的细菌。事实上,工作3小时后,短袖医生身上携带的细菌量就已经达到穿着未洗外套医生的一半了。所以在医院里请大胆穿长袖吧,如果说要洗点什么的话,就勤洗手吧!
