病人健康与医生是否常洗手有关

  CDC（疾病控制中心）称洗手是防止细菌传染的最佳方式。但医生、护士以及其它医护人员洗手的频率却达不到正常的一半。一些医院会贴标语，鼓励医生要多洗手预防自身疾病。不过，最近有一项更有说服力的研究表明：医生常洗手对患者有好处。这项研究来自《心理科学》期刊。【亚当 M·格兰特和大卫 A·霍夫曼《与我无关：为了患者健康，应鼓励医护人员多洗手》】

Investigators posted one of three signs at 66 soap and sanitizer dispensers in a US hospital. Either “Hand hygiene prevents you from catching diseases,” “Hand hygiene prevents patients from catching diseases,” or a control sign that read “Gel in, wash out.” Then they measured how much soap and gel disappeared after two weeks. And they asked a few docs and nurses to spy on their colleagues’ handwashing habits.

        研究者在美国一家医院66个肥皂与消毒剂存放处各贴上一张标语。标语的内容有“洗手有助于预防疾病”、“洗手有助预防患者生病”以及稍带强制语气的“请用洗手剂洗手”。他们观察两周内肥皂和消毒剂的使用情况，并请一些医生和护士观察同事们的洗手习惯。

Turns out hospital staff used 33 percent more soap and gel at dispensers with the message about patients. And the eyewitnesses found that staff was 10 percent more likely to lather up—especially nurses. A promising start. Though you can't blame patients for wishing docs and nurses washed their hands every time they should.

        事实验证，贴上洗手对患者有好处的标语后，肥皂和消毒剂的用量增加了33%。据观察，洗手时将肥皂和消毒剂搓揉起泡的人增加了10%，其中以护士居多。这是一个很好的开始。对患者来说，他们希望医生和护士该洗手的时候就得洗手，这也是没有没有错的。
