To check the rate of failure, hearing loss and its association with demographic variables and risk indicators for hearing loss in newborns submitted to the Newborn Hearing Screening in a secondary hospital.
Cross-sectional and retrospective study, involving 1,570 newborns submitted to the different stages of the Newborn Hearing Screening Program. Initially, we carried out otoacoustic emission tests (ILO Echocheck) and the cochlear-eyelid reflex. Afterwards, we analyzed the demographic and clinical characteristics of the newborns, screening rate of failure, hearing loss and its association with demographic variables and risk indicators.
Twenty-six newborns had failures in the first stages of the Program (1.7%), who were then referred to diagnostic evaluation. Of these, 16 (61.5%) did not come, two (7.7%) had normal results and eight (30.8%) were diagnosed with hearing disorders. The screening failure rate was 1.7% and the frequency of hearing disorders was 0.5%.
Pre-term newborns of very low birth weights had higher rates of screening failures and a greater occurrence of hearing changes. The factors associated with screening failure and hearing changes were similar to the ones described in the literature.
目的：检查失效率、听力损失及其与新生儿人口统计学变量和听力损失风险指标的关系，这些新生儿在一家二级医院接受了新生儿听力筛查。
材料与方法：这是一项横断面和回顾性研究，涉及到 1570 名接受新生儿听力筛查计划不同阶段检查的新生儿。最初，我们进行了耳声发射测试（ILO Echocheck）和耳蜗眼睑反射测试。之后，我们分析了新生儿的人口统计学和临床特征、筛查失效率、听力损失及其与人口统计学变量和听力损失风险指标的关系。
结果：该计划的前两个阶段有 26 名新生儿（1.7%）检查失败，随后被转介到诊断评估。其中，16 名（61.5%）未进行诊断评估，2 名（7.7%）检查结果正常，8 名（30.8%）被诊断为听力障碍。筛查失效率为 1.7%，听力障碍的发生率为 0.5%。
结论：极低出生体重的早产儿筛查失败率较高，听力变化发生率也较高。与筛查失败和听力变化相关的因素与文献中描述的因素相似。
