The use of the distraction test as a screen for hearing loss in infancy was reviewed in the Bristol and District Health Authority. Inaccuracies in data recording were found which challenged the screening and referral rates produced by the National Child Health Computer. Representative samples of children failing the distraction test and children needing hearing aids were followed up through the screening process. Of 130 children failing the test, only 46 (35%) had moderate conductive hearing loss and none had a severe loss. Of 34 children with sensorineural hearing loss (SNHL) requiring hearing aids, seven (21%) were identified by the test and five (15%) presented late after having been screened. The distraction test as now used in Bristol identifies large numbers of children with minor hearing loss. The referral of these children to the secondary services leads to delays for those children with more significant loss. The test is no longer the main method for identifying children with SNHL.
布里斯托尔及地区卫生局对采用分散注意力测试作为婴儿听力损失筛查方法进行了评估。发现数据记录存在不准确之处，这对国家儿童健康计算机系统得出的筛查和转诊率提出了质疑。对未通过分散注意力测试的儿童以及需要助听器的儿童的代表性样本进行了整个筛查过程的跟踪。在130名未通过测试的儿童中，只有46名（35%）患有中度传导性听力损失，没有一名患有重度听力损失。在34名需要助听器的感音神经性听力损失（SNHL）儿童中，该测试识别出7名（21%），另有5名（15%）在筛查后才很晚就诊。布里斯托尔目前使用的分散注意力测试识别出大量轻度听力损失儿童。将这些儿童转诊至二级服务机构会导致那些听力损失更严重的儿童延误治疗。该测试不再是识别SNHL儿童的主要方法。
