Centralized Newborn Hearing Screening in Ernakulam, Kerala , Experience Over a Decade. A two-stage centralized newborn screening program was initiated in Cochin in January 2003. Infants are screened first with otoacoustic emission (OAE). Infants who fail OAE on two occasions are screened with auditory brainstem response (ABR). All Neonatal intensive care unit babies undergo ABR. This successful model subsequently got expanded to the whole district of Ernakulam, and some hospitals in Kottayam and Thrissur districts. Over the past 11 years, 1,01,688 babies were screened. Permanent hearing loss was confirmed in 162 infants (1.6 per 1000). This practical model of centralized newborn hearing screening may be replicated in other districts of our country or in other developing countries.
