Newborn hearing screenings must be completed within 48 hours of birth.
To determine the optimal timing for the first transient evoked otoacoustic emissions (TEOAEs) test by comparing the referral rates of infants tested between different time intervals.
The present study was a retrospective cohort analysis of 2,713 newborns who underwent TEOAE tests between February 2021 and June 2022. The infants were categorized into groups according to the age at which they were tested: 12 to 24 hours, 25 to 36 hours, 37 to 48 hours, and > 48 hours. We compared referral rates across these groups.
The overall referral rate for infants tested within 48 hours from birth was 53%, significantly higher than the rate for those tested after 48 hours (46%, = 0.001). Notably, the highest referral rates were observed in neonates aged 25 to 36 hours. However, no significant difference in referral rates was found for high-risk infants tested either before or after 48 hours.
Transient evoked otoacoustic emissions can be used to screen newborns' hearing within 48 hours, but the high referral rate suggests that Thailand should add automated auditory brainstem response (AABR) to its guidelines for hearing evaluation if newborns leave the hospital before 48 hours.
新生儿听力筛查必须在出生后48小时内完成。
通过比较不同时间间隔接受测试的婴儿的转诊率，确定首次瞬态诱发耳声发射（TEOAEs）测试的最佳时机。
本研究是一项对2021年2月至2022年6月期间接受TEOAEs测试的2713名新生儿进行的回顾性队列分析。根据测试时的年龄将婴儿分为几组：12至24小时、25至36小时、37至48小时和>48小时。我们比较了这些组之间的转诊率。
出生后48小时内接受测试的婴儿的总体转诊率为53%，显著高于48小时后接受测试的婴儿的转诊率（46%，P = 0.001）。值得注意的是，25至36小时的新生儿转诊率最高。然而，48小时之前或之后接受测试的高危婴儿的转诊率没有显著差异。
瞬态诱发耳声发射可用于在48小时内筛查新生儿听力，但高转诊率表明，如果新生儿在48小时前出院，泰国应在其听力评估指南中增加自动听性脑干反应（AABR）。
