Hearing Screenings

Without hearing screenings average diagnosis of permanent hearing loss is greater than 2 years old. Late diagnosis of hearing loss has been one of the contributing factors of reduced language skills in children (Durieux-Smith, Fitzpatrick, & Whittingham, 2008). Since the early 1980s, the Joint Committee on Infant Hearing has published recommendations and multiple position statements which support the use of newborn hearing screenings, to decrease the age of diagnosis of children with permanent hearing loss. By 2000, there was a federal law to support universal newborn hearing screenings (UNHS). The law also promoted early intervention for children with hearing loss, in hopes to improve speech/language abilities for children with hearing loss …show more content…

TEOAE and AABR are two methods used for hearing screenings; however, after being compared to TEOAE, AABR is considered the preferred method when screening newborns (Benito-Orejas, Ramírez, Morais, Almaraz, & Fernández-Calvo, 2008). Presence of TEOAEs implies integrity of transmission of sound through the outer and middle ear and functional integrity of the outer hair cells in the inner ear. Whereas, AABR looks at the functional integrity from the 8th nerve through the auditory brainstem, which permits detection of neural conduction disorders (e.g. ANSD). When using the TEOAE screening protocol a greater number of children are referred than when using AABR, in turn this indicates that TEOAEs are less specific and AABR is more sensitive, thus, the percent of newborns referred for diagnosis reduces when using AABR (Benito-Oregas et al., 2008). As previously stated, AABR is the preferred method for UNHS programs as it provides less false positives, subsequently reducing the number of newborns referred for additional testing. This lowers unnecessary intangible costs (transportation fees, time off during follow-up, and family anxiety) (Benito-Oregas et al., 2008). With a sensitive and specific test protocol, screenings are more effective leading to earlier …show more content…

The study included children who received a diagnosis of a congenital or early-onset (before 6 months) permanent hearing loss that was not medically treatable (Durieux-Smith et al., 2008). Data was collected from the groups of children who were identified with permanent hearing loss through a targeted high-risk screening program, a universal newborn hearing-screening program, or through a medical referral either with risk factors or without factors. Data on the onset of permanent hearing loss, route to referral, etiology, age at diagnosis, and amplification fitting were all obtained from their medical charts to determine the primary outcomes of language abilities with early identification. Results from the study showed children screened at infancy were diagnosed earlier than those referred with risk factors (Durieux-Smith et al., 2008). Children with risk factors, in turn, were diagnosed earlier than referred without risk factors. Although, the age of diagnosis of referred children was seen to improve over time, it remained significantly higher than children receiving screenings. However, this trend of earlier diagnosis may reflect greater awareness of hearing loss. Results from this study indicate UNHS leads therefore earlier diagnosis and to earlier amplification, which then leads to earlier auditory stimulation (Durieux-Smith et al.,
