This study evaluated an alternative transient evoked otoacoustic emissions method for screening hearing in newborn babies that may reduce the referral rate of initial screening.
A total of 1,033 neonates (2,066 ears) from two hospitals were recruited. Subjects had their hearing screened in both ears using a combined approach-both click evoked OAEs (CEOAEs) and 1kHz tone burst evoked OAEs (TBOAEs).
1kHz TBOAEs were more robust than CEOAEs in terms of emission response level and signal-to-noise ratio (SNR) at both 1 and 1.5kHz frequency bands. The prevalence rate for CEOAE and TBOAE responses in these two frequency bands was significantly different. The combined protocol significantly reduced the referral rate-by almost 2 percentage points for first time screening.
The implementation of a combined 1kHz TBOAE/CEOAE screening protocol is a feasible and effective way to reduce referral rates, and hence false positive rates, in neonatal hearing screening programs.
本研究评估了一种用于新生儿听力筛查的替代性瞬态诱发耳声发射方法，该方法可能会降低初次筛查的转诊率。
招募了来自两家医院的1033名新生儿（2066只耳）。使用联合方法对受试者的双耳进行听力筛查，即同时采用短声诱发耳声发射（CEOAEs）和1kHz短纯音诱发耳声发射（TBOAEs）。
在1kHz和1.5kHz频段，1kHz TBOAEs在发射反应水平和信噪比（SNR）方面比CEOAEs更稳定。这两个频段中CEOAEs和TBOAEs反应的患病率存在显著差异。联合方案显著降低了转诊率——初次筛查时降低了近2个百分点。
实施1kHz TBOAE/CEOAEs联合筛查方案是降低新生儿听力筛查项目中转诊率及假阳性率的一种可行且有效的方法。
