Approximately 1-6 in every 1000 children are born with hearing loss. An automated auditory brainstem response (AABR) test is essential for screening newborns for abnormal hearing. At the tertiary hospital, we have been using a two-step AABR protocol for newborn hearing assessment since 2005. This study aimed to report the 10-year hearing screening results of newborns at the institution, and prove the efficacy of the two-step AABR protocol.
From August 2005 to January 2015, 3059 newborns were screened through AABR testing using the MASTER ABaer system. The first screening test was performed after the first 24 h of life. If a newborn was referred, the test was performed within 1 month after discharge from the hospital. The results were regarded as pass when the point optimized variance ratio was >3.5, using a stimulus level of 35 dB HL. When newborns were referred for the second AABR, they received follow-up tests including tympanometry, ABR, auditory steady-state response, and otoacoustic emission within 3 months.
A total of 3059 newborns underwent newborn hearing screening tests over a period of 10 years. One hundred and twenty (3.9%) newborns were referred with the initial AABR, and 104 (3.4%) were referred with a subsequent AABR. Of the newborns, 42 (1.37%) were confirmed to have a bilateral hearing impairment.
It is known that the referral rate for the AABR test is 3-4%, as recommended by the Joint Committee on Infant Hearing. Our data showed a referral rate of 3.4%. The two-step AABR test has been useful for screening hearing loss in newborns at tertiary hospital.
每1000名儿童中约有1 - 6名出生时患有听力损失。自动听性脑干反应（AABR）测试对于筛查新生儿听力异常至关重要。在三级医院，自2005年以来我们一直使用两步AABR方案进行新生儿听力评估。本研究旨在报告该机构10年新生儿听力筛查结果，并证明两步AABR方案的有效性。
2005年8月至2015年1月，使用MASTER ABaer系统通过AABR测试对3059名新生儿进行筛查。首次筛查测试在出生后24小时内进行。如果新生儿被转诊，则在出院后1个月内进行测试。当使用35 dB HL的刺激水平时，点优化方差比>3.5则结果视为通过。当新生儿被转诊进行第二次AABR测试时，他们在3个月内接受了包括鼓室图、ABR、听觉稳态反应和耳声发射在内的后续测试。
在10年期间，共有3059名新生儿接受了新生儿听力筛查测试。120名（3.9%）新生儿在初次AABR测试时被转诊，104名（3.4%）在后续AABR测试时被转诊。其中，42名（1.37%）新生儿被确诊为双侧听力障碍。
众所周知，婴儿听力联合委员会建议AABR测试的转诊率为3 - 4%。我们的数据显示转诊率为3.4%。两步AABR测试对于三级医院新生儿听力损失的筛查很有用。
