| Auditory Neuropathy Spectrum Disorder (ANSD) identified in well-baby nursery (WBN) newborn hearing screening.
Auditory Neuropathy Spectrum Disorder (ANSD) identified in well-baby nursery (WBN) newborn hearing screening.
Auditory neuropathy spectrum disorder (ANSD) is characterized by normal outer hair cell function and abnormal or absent auditory brainstem responses. A high proportion of ANSD has been identified while screening “high risk” infants from the neonatal intensive care unit (NICU). However, there is little data available regarding the prevalence of this condition in healthy newborns (WBN). This retrospective study examines the relative proportion of ANSD identified in each birth location (WBN vs. NICU) using data of Pediatrix’s-MEDNAX newborn hearing screen program which performs repeat inpatient/outpatient screens with automated auditory brainstem responses (AABR). The tracked audiological evaluations of infants identified with PHL (2,900) from 2015 -2016 out of the total population screened (WBN: 1,529,384; NICU 166,410) was analyzed. Amongst these 127 infants (4.3%, 127/2,900) were diagnosed with ANSD (62 bilateral, 65 unilateral) and 63% of the ANSD (81 infants) was identified in the WBN. The relative proportions of ANSD identified in the screened population were 0.005% (81/1, 529,384) in the WBN and 0.02% (46/166,410) in the NICU. In conclusion, the identification of ANSD in healthy infants from the WBN raises awareness for Early Hearing Detection and Intervention stakeholders suggesting that both screening methods (otoacoustic emissions and AABR) should be considered during outpatient follow-up testing for optimal management of infants with this condition regardless of their birth location.
