Abstract
A newborn hearing screening was conducted on 319 neonatal intensive care unit (NICU) and 1200 well-born nursery (WBN) infants. Mean NICU birth weight was 1997 g and mean gestational age 34 weeks. Auditory brainstem response was studied in screening in NICU infants. Otoacoustic emission (OAE) or automated auditory brainstem response (AABR) was used in primary WBN screening. All infants not bilaterally passing hearing screening before discharge were recalled for outpatient retesting. If the outcome was still failure, ABR screening was conducted. The prevalence of infants diagnosed with hearing loss was 1.1% (16 of 1519). Of these 16, 75% were from the NICU and 75% were at risk for hearing loss. Mean age at hearing loss identification was 12.9 weeks in the WBN and mean age at hearing aid fitting was 16.1 weeks. Mean age at hearing aid fitting was lower for WBN than for NICU infants. Hearing loss identification and hearing aid fitting are thus feasible in NICU and WBN infants in universal newborn hearing screening.
