Results of an Early Hearing Detection Program

Abstract

Introduction and objectivesNeonatal hearing loss is a public health problem that meets the requirements for submission to universal screening. Our objective was to analyse the results of the early hearing detection and intervention program implemented at our centre between January 2007 and December 2010. MethodsWe studied 26,717 newborns during the period mentioned, using transient otoacoustic emissions (TOAEs) for the screening. The diagnostic phase was carried out at the hearing loss department. ResultsIn our area, there were 27,935 births between January 2007 and December 2010. The screening was performed on 26,717 children. Of these, 24,173 had positive TOAEs, 1040 had no TOAEs and 1504 presented TOAEs in 1 ear with absence of TOAEs in the contralateral ear. Risk factors associated with hearing loss were found in 4674 infants. In a second phase of the program, TOAEs were given to 5156 children, of whom 4626 had positive otoacoustic emissions in both ears, 323 had no TOAEs in 1 ear and 207 failed this second phase. Of all children studied, 3.8% were referred to auditory brainstem response (ABR) testing and 26 children entered the cochlear implant program. The program achieved a coverage of 95.64%. ConclusionsThe early hearing detection and intervention program at our hospital is suitable for our environment, achieving 95.64% of coverage. We consider the relationship between effectiveness and efficiency to be positive.
