Challenges of Universal Newborn Hearing Screening in a Developing Country-a Double-Edged Sword.

Objective to implement Universal Neonatal Hearing Screening (UNHS) in a tertiary academic hospital and identify associated risk factors. Prospective study. Screening tests with Otoacoustic Emissions (OAE) were done among newborns, prior to hospital discharge. In babies who fail OAE twice, Brain Response Audiometry (BERA) was done, failing which they were referred to higher ENT center for repeat testing and hearing rehabilitation. A total 2323 babies were admitted in the neonatal unit during the study period. Only 773 babies (a third) could be screened for the first OAE, two thirds being lost to study right at inception!! Among the 773 neonates, in the "at risk" group of 301 neonates, 31(10%) and in the "not at risk" group of 472 neonates, 30 (6%) were lost to follow up respectively. The occurrence of hearing loss in this study population was 1.3 per 1000. Risk factors were noted in 38.9% of this subgroup with occurrence of hearing loss in "at risk" group being 3.32 per 1000. The implementation of UNHS in a developing country like India, has multiple challenges including infrastructural and non-compliance to follow up. In the meantime, the possibility of compromising 'at-risk" neonates, who are significantly more prone to hearing loss, both neonatal and delayed onset, is an additional grave reality which needs deep considerationin this Herculean task of attaining "universality". © Association of Otolaryngologists of India 2020.
