We have examined the observer variation in the detection of physical signs in airways obstruction. In the first study, 10 relatively experienced physicians examined 11 patients for the presence of six familiar signs and seven less well-known signs. Six experienced observers then underwent a training period after which they examined another group of 21 patients. The repeatability of all the signs fell about midway between that expected by chance and the maximum possible. There was no difference between the familiar and unfamiliar signs. The training period resulted in a slight but not significant improvement in reliability.
我们研究了气道阻塞体征检测中的观察者差异。在第一项研究中，10名经验相对丰富的医生对11名患者进行检查，以确定6种常见体征和7种不太知名体征的存在情况。然后，6名经验丰富的观察者接受了一个培训阶段，之后他们检查了另一组21名患者。所有体征的可重复性大约介于偶然预期和最大可能值之间。常见体征和不常见体征之间没有差异。培训阶段使可靠性有了轻微但不显著的提高。
