The literature on neonatal hearing screening by means of oto-acoustic emissions (OAE's) presents various prevalence figures, and gives little quantitative information on the procedure used to score the recordings. If the OAE test is to be interpreted by users who do not have the opportunity to develop intuitive interpretation skills through extensive training, a clear numerical decision criterion is needed. The present paper discusses the scoring procedure used by 25 teams, which together screen 22,356 neonates annually. More than 60% of the groups involved in this study use visual interpretation of the recorded OAE response, together with numerical criteria. Amongst the teams, 21 different ways of numerical scoring are used. It is shown that for a given set of OAE recordings, prevalence varies from 61% to 90%, depending on the numerical decision criterion being applied. We conclude that at this moment no consensus exists regarding the numerical criterion to be used when assessing OAE screening results. In view of the strong effect of criteria on the outcome of OAE screening, such consensus is urgently needed, but should be based on sensitivity and specificity figures for each scoring technique.
关于通过耳声发射（OAE）进行新生儿听力筛查的文献给出了各种患病率数据，但对于用于记录评分的程序几乎没有提供定量信息。如果OAE测试要由没有机会通过广泛培训培养直观解释技能的用户来解读，那么就需要一个明确的数值判定标准。本文讨论了25个团队所使用的评分程序，这些团队每年共筛查22356名新生儿。参与本研究的超过60%的团队采用对记录的OAE反应进行视觉解读，并结合数值标准。在这些团队中，使用了21种不同的数值评分方式。结果表明，对于给定的一组OAE记录，患病率在61%至90%之间变化，这取决于所应用的数值判定标准。我们得出结论，目前在评估OAE筛查结果时，对于应使用的数值标准尚未达成共识。鉴于标准对OAE筛查结果有很大影响，迫切需要达成这样的共识，但应以每种评分技术的敏感性和特异性数据为基础。
