          Summary

          Since 1998, after we started the support group for neonatal hearing screening, many other hearing screening programs were held in Brazil. In Alagoas, the first program started in 2003, but none of its results were published. Hearing is paramount for human communication; therefore, childhood hearing loss can impair speech acquisition, emotional, educational and social development. Aim: to present the results achieved in a neonatal hearing screening program in Maceió. Materials and Methods: a retrospective analytical study was carried out in order to study the results from tests carried out from September 2003 to December 2006 in a private hospital of Maceió. Results: from a total of 2002 newborns, 1,626 fitted the inclusion criteria, 835 (51.4%) males. The hearing screening was considered appropriate in 1416 cases (87.1%), and the most frequently found age was between 16 and 30 days. Finally, 163 (10.0%) children presented risk indicators for hearing loss, and hyperbilirubinemia was the most common indicator. Conclusions: statistical results obtained from this hearing screening program show the importance of holding such programs. This study is important because it contributes to further regional or multinational studies.

          The newborn with hearing loss: detection in the nursery.

          Early detection of hearing loss coupled with appropriate early intervention is critical to speech, language, and cognitive development. These competencies serve as the foundation for later academic skills. For these reasons, many states are undertaking aggressive efforts to screen all newborns before hospital discharge. Universal detection of hearing loss in newborns is a three-stage process composed of 1) the birth admission screen, 2) follow-up and diagnosis, and 3) intervention services. Breakdown at any stage jeopardizes the entire effort. The goals of this research are to examine the birth admission screen by reviewing outcome measurements for 54 228 Texas newborns and to evaluate factors that impact outcomes positively or negatively. All newborns were screened for hearing loss using a physiologic test of auditory function; either screening auditory brainstem responses or transient evoked otoacoustic emissions. Screening occurred in the newborn and intensive care nurseries, before hospital discharge in 9 sites as part of the nursery protocol. Patients. A total of 54 228 newborns were available for screening. Four measures were evaluated and are reported: the number of births screened, the number of newborns who passed the screen before discharge, the number of infants who returned for follow-up, and the number of infants identified with hearing loss. A Birth Screening Performance Index is also calculated. Results are reported for calendar years 1994, 1995, 1996, and through June 1997. A total of 54 228 newborns were available for screening; 52 508 were screened before hospital discharge during their birth admission and 50 721 passed this screen. Infants returning for follow-up screen as outpatients numbered 1224. Over this 31/2-year span, 113 infants who failed the birth admission screening had hearing loss that was sensorineural in nature. From these data, the estimated incidence of hearing loss is 3.14/1000 infants. Screening in the nursery with low false-positive rates can be achieved when three elements are present: audiology involvement, hospital support, and automated data and information management. Follow-up measures need improvement. Better tracking methods may help assure that at-risk newborns are connected to services.

              Otoacoustic emission tests in neonatal screening programmes.

              Otoacoustic emission (OAE) testing has many characteristics which suit it for use as an objective neonatal auditory screener. The most important of these is the speed with which it can be performed. This feature alone opens up the possibility of much more general neonatal screening programmes. We here review the important considerations in applying otoacoustic testing to neonatal screening applications, and discuss the future role of OAE testing. Practical considerations in applying the technique are illustrated by examples and experiences drawn from a pilot whole-population neonatal screening project. Unselected screening takes us into unexplored territory. Test failure rate will inevitably far exceed the real incidence of hearing impairment. The concept of rapid whole-population neonatal OAE screening techniques as an additional risk factor detector rather than a definitive hearing test seems more appropriate to the low incidence of hearing impairment in the population and to the ethical problems surrounding early and erroneous diagnosis of hearing impairment.
