RESUMO

Introduction: The Newborn Hearing Screening Program have been responsible for anticipating the sensorineural and conductive hearing loss diagnoses for the last few years. This study refers to the experience of a hearing screening starting before the hospital discharge in the Neonatal Intensive Care Unit (NICU) and also to the orientation to the Well-baby Nursery screening after the discharge. Aims: Describe a Newborn Hearing Screening Program in a maternity hospital of the privative network in Salvador, from 2000 to 2006, considering the historical context, the process of implementation, the changes through the years, as well as the hearing findings and the relation with the quality criteria proposed by the Joint Committee on Infant Hearing 2000.Method and Material: This is a retrospective, cross-sectional study. 4997 newborns and infants were screened through the use of Echocheck, the otoacoustic emissions equipment and through the observation of the cochlear-palpebral reflex. The results were divided in four groups: AI = NICU and screening in the pre-discharge; AII = NICU and screening in the post-discharge; BI = Well-baby Nursery and screening in the pre-discharge; BII = Well-baby Nursery and screening in the post-discharge. Results: A description of the evolution and implementation process of the hearing screening from 2000 to 2006 was done; in relation to the audiological findings, the hearing screening results described were the ones from 2001 to 2006. There was an assessment of 38,9% of the newborns and infants in 2001, and 79,5% in 2006. According to the pre-discharge service analyses, the group AI/BI had from 8,1% to 11,2% of fails; in the post-discharge service analyses, the group AII/BII maintained the fail index in 2,6%. As final results of the AI/BI group, from the total of 1739 screenings, there were 21 confirmed cases of hearing alterations, being 20 conductive(6,1:1000) and 4 sensorineural (1,2:1000). Conclusion: The data indicates that the service before the discharge to the NICU and a gradual extension to the Well-baby Nursery is workable, ever since the protocol is continuously adjustable. Although the AI/BI group was the third part of the sample it represented a higher prevalence of hearing alterations. These show the importance of the hearing screening before the hospital discharge, so a higher number of congenital hearing problems can be assessed
