Most newborns are screened for hearing loss, and many hospitals use a 2-stage protocol in which all infants are screened first with otoacoustic emissions (OAEs). In this protocol, no additional testing is done for those passing the OAE screening, but infants failing the OAE are also screened with automated auditory brainstem response (A-ABR). This study evaluated how many infants who failed the OAE and passed the A-ABR had permanent hearing loss (PHL) at 8-12 months of age.
A total of 86,634 infants were screened at 7 birthing centers using a 2-stage OAE/A-ABR hearing screening protocol. Of infants who failed the OAE but passed the A-ABR, 1,524 were enrolled in the study. Diagnostic audiologic evaluations were performed on 64% of the enrolled infants (1,432 ears from 973 infants) when they were 8-12 months old.
Twenty-one infants (30 ears) who passed the newborn A-ABR hearing screening were identified with PHL when they were 8-12 months old. Most (71%) had mild hearing loss.
If all infants were screened for hearing loss using a typical 2-stage OAE/A-ABR protocol, approximately 23% of those with PHL at 8-12 months of age would have passed the A-ABR.
大多数新生儿会接受听力损失筛查，许多医院采用两阶段方案，即首先对所有婴儿进行耳声发射（OAE）筛查。在此方案中，通过OAE筛查的婴儿无需进行额外检测，但未通过OAE筛查的婴儿还需接受自动听性脑干反应（A-ABR）筛查。本研究评估了OAE筛查未通过但A-ABR筛查通过的婴儿在8至12个月大时永久性听力损失（PHL）的情况。
在7个分娩中心，共86,634名婴儿采用两阶段OAE/A-ABR听力筛查方案进行了筛查。在OAE筛查未通过但A-ABR筛查通过的婴儿中，有1,524名纳入研究。当这些婴儿8至12个月大时，对其中64%（来自973名婴儿的1,432只耳朵）进行了诊断性听力评估。
有21名婴儿（30只耳朵）在8至12个月大时被确诊为永久性听力损失，他们通过了新生儿A-ABR听力筛查。大多数（71%）为轻度听力损失。
如果所有婴儿都使用典型的两阶段OAE/A-ABR方案进行听力损失筛查，那么在8至12个月大时患有永久性听力损失的婴儿中，约23%的婴儿将会通过A-ABR筛查。
