“…We found that the prevalence of HL for babies admitted to the NICU was 1.5% which is comparable with the results of the study done by Khairi et al 4 . However, our prevalence was lower compared to other studies 3,9 . The low prevalence may be explained by the low number of babies (49%) who had completed the diagnostic test.…”

“…Babies requiring intensive care in the Neonatal Intensive Care Unit (NICU) were reported to have a higher prevalence of HL, involving up to 46% of newborns admitted to the NICU 2 . In 2018, Parab et al 3 reported a higher prevalence of HL amongst high risk babies, as 10.6 per 1000 high risk births compared to healthy neonates. A study in Malaysia in 2005 reported that 1% of high risk neonates in the NICU had HL 4 .…”

Objective: To study the prevalence of hearing loss (HL) and to identify the possible risk factors causing HL. Methods: This retrospective study was conducted from January 2014-December 2016 at a tertiary hospital in Malaysia. All neonates admitted to the neonatal intensive care unit (NICU), Universiti Kebangsaan Malaysia Medical Centre (UKMMC) were screened with a two-step protocol using an automated auditory brain response (AABR) and/or Otoacoustic Emission and auditory brain response (ABR). Descriptive analysis was used for the prevalence of HL, degree of HL and number of risk factors per infant. Results: A total of 2713 babies underwent hearing screening in NICU was enrolled in this study. Two thousand six hundred eight (96%) babies passed the screening test and 214 (4%) babies required further diagnostic test. Only 105 (49%) babies completed diagnostic tests. Out of 105 babies, 40 (38.1%) babies had HL. Mild HL was the commonest HL with 22 (55%), moderate HL was in seven babies (17.5%), severe HL in two babies (5%), and profound HL in nine babies (22.5%). The presence of craniofacial anomalies was the only significant independent risk factor for HL with p<0.05 with an odds ratio of 0.105 CI 95% [0.028-0.389]. Of Babies with the presence of three or more risk factors, 100% of them had HL. There was an increased risk of hearing loss in those with craniofacial anomalies up to 11 times higher compared to those without such anomalies. Conclusion: The prevalence of HL among the NICU babies was 1.5% and mild HL was the commonest degree of HL (55%).

“…Stay at NICU, mechanical ventilation, ototoxic drug (aminoglycoside exposure), oxygen need and history of deafness in the family positively correlated with the hearing loss. No significant association between hearing loss and congenital disease (cytomegalovirus), bacterial meningitis, streptococcus positivity, loop diuretic exposure and ECMO [ 20 ].…”

Babies in Neonatal Intensive Care Units (NICU) have an additional risk for hearing loss due to various risk factors like, prematurity, low birth weight, mechanical ventilation, hyperbillirubinemia, ototoxic drugs, low APGAR score etc. as compared to the babies from well baby nursery (WBN) who, poses risk factors mostly family history, syndromic deafness. So the present study was aimed know the risk factors responsible for hearing loss in NICU and WBN babies and to assess the incidence of deafness. A total of 800 babies from NICU ( n = 402) and WBN ( n = 398) underwent hearing screening from a tertiary care center. Hearing screening was done using two staged screening protocol as per JCIH guidelines with Distortion product Evoked Otoacoustic Emissions (DPOAE) and Automated Auditory Brainstem Responses (A-ABR). According to DPOAE test, 311 from NICU and 383 from WBN passed the test and during second screening, 80 out of 91 from NICU and 11 out of 13 from WBN passed the DPOAE test. Further BERA was done at the 3 rd month of corrected age where 6 out of 11 showed positive responses from NICU and 3 babies from WBN had profound hearing loss. Data analysis revealed that family history of deafness, anemia and hypertension in ANC, TORCH in mother, low Apgar score and hyperbillirubinemia in newborns were a major risk factor for hearing impairment. We conclude that the diagnoses of auditory disorders at early stage due to various risk factors are important since appropriate therapeutic intervention and rehabilitation would help in better development of children.

“…Hearing impairment in neonates ranged from 1.59 to 8.8 per 1000 screened in studies where auditory brainstem response audiometry (ABR) was done after failing otoacoustic emission (OAE) twice. [13][14][15][19][20][21][22] ABR (AABR) double screening, followed by a conventional ABR or auditory steady state response (ASSR) audiometry showed a similar frequency of 2.2-4.1 per 1000. 16,18 A single OAE followed by ABR showed a much higher failure rate of 22.1/ 1000, falling to 1.42/1000 bilateral HL after a complete audiological assessment.…”

“…Hearing impairment in neonates with risk factors ranged from 7 to 49.18 per 1000. [13][14][15]19,22 Neonatal intensive care unit admissions, mechanical ventilation, low birth weight, prematurity, hyperbilirubinaemia, congenital anomalies or syndromes and family history of HL were the most common factors used to identify at-risk infants. Dar et al 21 noted that cytomegalovirus causes a 20-fold increase in early onset or congenital HL.…”

Background Despite abundant literature, a clear and coherent understanding of hearing loss (HL) in India is limited by the wide disparity in studies. Methods We did a review of published peer-reviewed journal articles. Studies reporting the prevalence and degree of HL in India from 1980 to 2020 were included. Information was gathered on the population characteristics, methodology applied and the prevalence of hearing impairment. The data were analysed to identify trends and at-risk sections of population in various categories. Results Four hundred and forty studies were identified after a database search; 29 full-length articles were selected for final analysis. Using a 3-step screening protocol, hearing impairment (abnormal auditory brainstem response/auditory steady state response) in neonates ranged between 1.59 and 8.8 per 1000 births. Among ‘at risk’ neonates, it ranged from 7 to 49.18 per 1000 births. In children the prevalence of HL was 6.6% to 16.47%. Otitis media was the most common cause of HL in children. Community-based studies (all ages) reported prevalence of HL between 6% and 26.9% and prevalence of disabling HL between 4.5% and 18.3%. Rural areas and elderly showed a higher prevalence of hearing impairment. Conclusion Despite India’s improving health indices, hearing disability remains persistently high. It is a major contributor to the loss of personal potential and a financial strain for the individual and the country. A large-scale multicentric study to identify the degree and type of HL, social awareness campaigns, widespread neonatal screening, strengthening treatment facilities and well-funded rehabilitation programmes can counter the rising prevalence of hearing impairment.
