ABSTRACT INFORMATION
Title: 'Maximizing the Power of Newborn Hearing Screening: Advantages of a Dual Protocol' Track: 2 - Audiological Services Keyword(s): OAE, AABR, risk factors, dual screening protocol Learning Objectives: appraise the merit of a dual screening protocol in increasing the sensitivity to hearing loss and otitis media. review their own facility's screening protocol for sensativity and specificity. consider the benefits of screening for otitis media at an early age. Abstract: A dual newborn hearing screening using both OAE and AABR was performed on 375 infants at the Nemours duPont Hospital for Children. Of these, 47.5% were seen as inpatients and 28.5% had a risk factor for late onset hearing loss present at the time of screening. For infants who did not pass one or both technologies in either ear, a follow up screen including tympanometry was performed within a few weeks. The overall refer rate was 28.8% and the refer rate for OAEs only was 14.9%. Of the ears that did not pass the OAE, 79% right and 89% left had an abnormal tympanogram at a follow up visit. Ten children were eventually diagnosed with permanent hearing loss, 51 were referred for ENT management and 13 were lost to follow up including one deceased. The sensitivity and specificity for each technology alone and the technologies combined are discussed. AABR alone has the advantage of screening for neural as well as sensory hearing losses and enjoys the highest specificity of any screening protocol. Adding OAEs to a screening protocol increases the sensitivity even further but decreases its specificity. We propose using the AABR pass/fail criteria alone to dictate an infant’s screening result and using a fail result on OAE as an indicator to Primary Care and families that the infant may be at risk for otitis media or other hearing problems and that a behavioral evaluation to include tymps, reflexes and OAEs is indicated at 6-9 months of age. This protocol may not meet the needs of every facility; however, otitis media is the most common cause of childhood hearing problems and a leading cause of speech delay. Using OAEs to screen early-on for this malady may be an appropriate use of resources for some screening programs.
