“…These rates can even increase in preterm infants [13][14][15] and newborns younger than 48 h up to 60% [16][17][18][19]. AABR tests yield lower first-screening referral rates (1-4%) [7][8][9]11,[20][21][22].…”

SummaryObjective: Both transitory auditory otoemissions (TEOAE) and automated auditory brainstem responses (AABR) are considered adequate methods for universal hearing screening. The goal of this study was to compare the results obtained with each device, applying the same screening procedure. The population studied included all well newborns and those admitted to neonatal intensive care units (NICU). The first screening was normally undertaken with well babies during the first 48 h of life, before hospital discharge. Infants referred from this first step underwent a second screening after hospital discharge, before they were a month old. Results: The results from each study group were compared and analyzed for significant differences. TEOAE screening yielded 10.2% fail results from the first screening step; AABR gave 2.6%. In the second screening step, 2% of the newborns screened with TEOAE were referred, whereas 0.32% of those screened with AABR were referred. These differences are statistically significant.

“…Em outro estudo, realizado em UTI neonatal, utilizando a AABR em duas etapas, observou-se 8 e 3,1% de falha na triagem e confirmação do diagnóstico por ABR convencional em 2,5%. O exame realizado próximo à alta apresentou maior especificidade 18 .…”

Objective: Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Womens Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors.Methods: 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The result was considered normal when the newborn showed response to a 35dBNA signal bilaterally. The prevalence of AABR impairment and the odds ratio were analyzed with a 95% confidence interval using bivariate analysis. To identify the independent risk factors for hearing alterations, multivariate analyses were used with logistic regression.Results: The prevalence of AABR impairment was 10.2%, of which 5.3% was unilateral and 4.9% bilateral. From the multivariate analyses, the following observations were made: family history of congenital hearing loss (OR = 5.192; p = 0.016), craniofacial deformity (OR = 5.530; p < 0.001), genetic syndromes associated with hearing loss (OR = 4.212; p < 0.001), weight below 1,000 g (OR = 3.230; p < 0.001), asphyxia (OR = 3.532; p < 0.001), hyperbilirubinemia (OR = 4.099; p = 0.002) and use of mechanical ventilation (OR = 1.826; p < 0.031) were the indicators that best characterized the group at risk for hearing impairment. Conclusions:The prevalence of hearing impairment using AABR is high. Therefore, it is essential for all newborns who present isolated or associated risk factors to undergo hearing screening in situations in which it is not possible to have universal hearing screening.J Pediatr (Rio J). 2006;82(2):110-4: Newborn, diagnosis, hearing loss. ResumoObjetivo: Avaliar a prevalência de alterações auditivas em recém-nascidos internados na unidade de terapia intensiva e cuidados intermediários do serviço de neonatologia do Centro de Assistência Integral à Saúde da Mulher, Faculdade de Ciências Médicas, Universidade Estadual de Campinas, e analisar os fatores de risco associados.Métodos: Foram avaliados 979 recém-nascidos no período de janeiro de 2000 a janeiro de 2003, utilizando-se a audiometria automá-tica de tronco encefálico (AABR), com aparelho ALGO-2e color -Natus. O resultado foi considerado normal quando o recém-nascido apresentou resposta para 35 dBNA bilateralmente. Foi analisada a prevalência de AABR alterada e odds ratio com intervalo de confiança de 95% em análise bivariada. Para identificar os fatores de risco independentes para AABR alterada, foi feita análise múltipla com modelo de regressão logística.Resultados: A prevalência de alteração no AABR foi de 10,2%, sendo 5,3% unilateral e 4,9% bilateral. Pela análise multivariada, observamos que: antecedente familiar (OR = 5,192; p = 0,016), malformação craniofacial (OR = 5,530; p < 0,001), síndrome genética (OR = 4,212; p < 0,001), peso menor que 1.000 g (OR = 3,230; p < 0,001), asfixia (OR = 3,532; p < 0,001), hiperbilirrubinemia (OR = 4,099; p = 0,002) e uso de ventilação mecânica (OR = 1,826; p < 0,031) foram os in...

Implementation of a nation-wide automated auditory brainstem response hearing screening programme in neonatal intensive care units

Abstract: A financially supported two-stage AABR hearing screening programme can be successfully incorporated in NICU centres and detects a high prevalence of CHL in NICU graduates. Neonatal hearing screening should be part of standard clinical practice in all NICU infants.
