During 16,070 consultations in general practice 70 adults complained of difficulty with hearing. A simple poster displayed in the waiting areas together with an accompanying leaflet almost doubled the incidence of presentation of loss of hearing. Nevertheless, more than half of those complaining had failed to notice the prominently displayed personally relevant message, and the beneficial effect was lost almost as soon as the poster was removed.
在16070次全科诊疗中，有70名成年人抱怨听力有问题。在候诊区展示一张简单的海报并附上一份传单，几乎使听力丧失症状的就诊率翻了一番。然而，超过一半的抱怨者没有注意到显著展示的与个人相关的信息，而且海报一撤下，这种有益效果几乎就消失了。
