The use of a computer program for diagnosing acute abdominal pain in children using Bayes' theorem is described and the results of a one-year trial are analysed in order to qualify and quantify the accuracy of the system and to suggest some of the educational benefits that might be obtained. A means of feedback to medical students is described which can localise their weaknesses based on their experiences of real patients and could be used by educators to measure the effectiveness of their courses and the major areas of difficulty being encountered by the students. The computer has in this instance achieved a remarkable degree of accuracy in view of several factors acting against it. Such experience is very encouraging for further endeavour in this area.
本文描述了一种使用贝叶斯定理诊断儿童急性腹痛的计算机程序，并分析了为期一年的试验结果，以确定该系统准确性的合格标准和量化指标，并提出可能获得的一些教育益处。文中还描述了一种向医学生提供反馈的方法，该方法可以根据他们对真实患者的诊断经验定位其弱点，教育工作者可以利用该方法来评估课程的有效性以及学生遇到的主要困难领域。鉴于存在诸多不利因素，该计算机在此次试验中仍达到了相当高的准确率。这样的经验对于该领域的进一步探索非常具有鼓舞作用。
