Five obstetrician-gynecologists experienced in fetal monitoring assessed 150 intrapartum cardiotocograms obtained with an external transducer. There were three successive blind readings, the first two without any clinical data apart from gestational age. The reviewers indicated whether the tracings showed definite, possible or no abnormalities. The interpretations given by each reviewer for any one tracing were fairly consistent, but they varied markedly from one reviewer to another. The proportion of tracings interpreted as normal ranged from 39% to 74%, and the proportion assessed as abnormal ranged from 3% to 43%. All five observers agreed on the interpretation of 29% of the tracings. Inter-reviewer reproducibility scarcely changed when clinical data were provided. These findings emphasize the need to evaluate all methods of fetal monitoring before they become widespread.
五位在胎儿监测方面经验丰富的妇产科医生对通过外部传感器获得的150份产时胎心监护图进行了评估。进行了连续三次盲法阅读，前两次除了孕周外没有任何临床数据。评审人员指出这些描记图是否显示明确、可能或无异常。每位评审人员对任何一份描记图的解读相当一致，但不同评审人员之间差异明显。被解读为正常的描记图比例在39%至74%之间，被评估为异常的比例在3%至43%之间。所有五位观察者对29%的描记图解读一致。提供临床数据后，评审人员之间的可重复性几乎没有变化。这些发现强调在胎儿监测方法广泛应用之前对其进行评估的必要性。
