“…Various studies have reported a prevalence of hearing impairment ranging from 0.09 to 2.3% in normal neonates and 0.3 to 20.68% in high risk infants. [1][2][3] In 1999, the American Academy of Pediatrics (AAP) advocated Universal screening of newborn hearing before 3 months and remedial measures, to maximize linguistic and communicative competence and literacy development for hearing impaired children. 4 The Joint Committee on Infant Hearing (JCIH) has also proposed necessary guidelines and the risk indicators, which can be locally adapted to identify infants at risk.…”

Background: Hearing loss in early life can have deleterious effects on child’s psychosocial, scholastic and social-emotional development. Early identification and timely intervention can provide the child with better speech and language development. This study has been done to estimate the prevalence of hearing impairment among high risk infants as per Joint Committee on Infant Hearing (JCIH) criteria and to study the risk factors associated with neonatal hearing impairment.Methods: This multicentric observational study was conducted among 613 high risk infants admitted and discharged from neonatal intensive care units (NICU) of Academy of Medical Sciences, Kannur, Kerala and Sri Siddhartha Medical College and Research Centre, Tumakuru, Karnataka, India (level III neonatology units with an NICU admissions of average around 1200 per year), during the period August 2015 - August 2016 (12 months). The babies were selected based on the JCIH 2007 criteria. All babies were subjected to behavioral audiometry (BA) and Oto Acoustic Emissions (OAE), preferably within 3 weeks. Those failing OAE were reevaluated at 6th week and with Auditory brain stem response (ABR) within 3 months time. Results: A total of 613 high risk babies were screened. 42 (6.76%) among them were having hearing impairment. The most common risk factors associated with hearing impairment was NICU stay for more than 24 hours, prematurity, low birth weight and meningitis/sepsis etc.Conclusions: Hearing impairment among high risk babies is not a rare condition. In our study, the prevalence was 6.76%. Low birth weight, admission to NICU for more than 24 hours, low APGAR, meningitis/sepsis, maternal and neonatal complications are significant risk factors for hearing impairment among neonates. This highlights the need for neonatal screening. Though we recommend a universal screening program, at least a targeted approach should be practiced in neonatal care. Those babies who are found to have hearing impairment should be closely followed up with early intervention and rehabilitation.

Background: Present study was conducted to assess the prevalence of hearing impairment using measurements of Otoacoustic Emission (OAE) in newborns admitted to NICU and to determine the risk factors predictive of hearing impairment in these newborns.Methods: The study was conducted from January 2016 to June 2017 in the NICU under the Department of Pediatrics. All neonates admitted for more than 48 hours in the NICU were included. Neonates who died during the study period were excluded. All candidates underwent hearing loss in a sound treated room in the department using Distortion Product Otoacoustic Emissions (DPOAE) test at the time of discharge. Babies who failed this initial screening underwent another OAE test within 1 month after discharge, and those who failed the test again were referred to an Otologist for comprehensive audiological assessment at 3 months.Results: Of the 200 neonates included in the study, 101cases (50.5%) failed the initial screening. 1 case (0.5%) failed the second OAE screening and moderate hearing loss was diagnosed in this child using BERA. Risk factors included mechanical ventilation (p=0.01), prematurity (p=0.01), low Apgar scores (p<0.01) and multiple gestation (p<0.05). Other conditions predominating in neonates who failed hearing screening included TTN, MAS, LBW and neonatal jaundice.Conclusions: Newborn infants admitted to the NICU are at a higher risk for hearing impairment due to exposure to multiple risk factors. The two staged screening protocols with DPOAE is a useful protocol for detecting hearing loss in newborns and can be implemented as a national program.

“…Medical College, Ajmer, between 2013 and 2014, found a staggering prevalence of unilateral and bilateral hearing loss of 150 per thousand. 11 A study by Regina et al on 613 high-risk neonates discharged from NICU of Academy of Medical Sciences, Kannur, Kerala, and Sri Siddhartha Medical College and Research Centre, Tumakuru, Karnataka, between August 2015 and August 2016 based on behavioral audiometry, OAE, and auditory brainstem response (ABR) found 42 cases of hearing impairment, representing prevalence of 67.6 per 1,000 neonates. 12 Study on neonates admitted to the NICU at Nemazee Hospital, Shiraz University of Medical Sciences, between January 2006 and January 2007 shows higher prevalence of hearing loss in newborns with a gestational age of less than 36 weeks.…”

Aim The aim of this study was to find out the prevalence of hearing impairment in high-risk neonates born in Dr. R.N. Cooper Hospital and H.B.T Medical College and establish the fact that high-risk neonates have higher prevalence of hearing impairment compared with normal population. Materials and Methods A prospective observational study was conducted over a period of 1 year starting from March 2016 and involved three-stage screening of 410 neonates admitted to neonatal intensive care unit of Dr. R.N. Cooper Municipal General Hospital and H.B.T Medical College, Vile Parle (west), Mumbai. All enrolled neonateswere screened by a three-stage screening mechanism. First otoacoustic emission (OAE-1) screening was done within 24 to 72 hours of birth. Parents of neonates referred by OAE-1 were instructed to come back within 28 days for repeat OAE test (OAE-2). Those referred by OAE-2 were asked to come back after further 2 months for brainstem-evoked response audiometry. Data collected in the study were processed using Microsoft Excel. Results and Conclusion In the current study, out of 410 neonates who were screened by a three-stage screening mechanism, five including three girls and two boys were found to be suffering from profound sensorineural hearing loss. Observed prevalence of 12.20 (or 12 on rounding off to nearest digit) per 1000 in high-risk neonates is much higher compared with the prevalence of 1 to 6 per 1000 live births in overall population as reported by the American Speech-Language-Hearing Association.
