Bai JS, Gowda P R P, Naik SM, Somashekhar A. Hearing Screening in High-Risk Neonates Using Distortion Product Oto-Acoustic Emission. Indian J Otolaryngol Head Neck Surg 2024; 76:620-625. [PMID: 38440481 PMCID: PMC10908932 DOI: 10.1007/s12070-023-04227-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 09/07/2023] [Indexed: 03/06/2024] Open
Abstract
The prevalence of hearing loss is 0.09-2.3% in low risk neonates, and 0.3-14.1% in the high-risk population. The treatment requires early identification by neonatal hearing screening and early rehabilitation. OAE (oto-acoustic emission) and ABR (Auditory Brain Response) are the two objective tests used to evaluate hearing loss in neonates. OAE tests the biological response of the cochlea to auditory stimuli. ABR tests the auditory pathway. The aim is to estimate hearing loss in high-risk neonates using the Distortion Product Oto- acoustic emission (DP OAE) and to correlate the associated high-risk factors. This was a cross-sectional study conducted between March 2021 to September 2022. Newborns satisfying the inclusion criteria were included in the study. DP- OAE is performed to screen for hearing loss within 48 h of birth. Infants failing the first screening test are then examined for treatable causes and then repeated at 2 weeks. Newborns who fail the second DP-OAE are subjected to ABR for confirmation of hearing loss. A total of 100 high risk neonates underwent hearing screen using DP-OAE. Most common risk factors seen in our study are prematurity (22%), Low birth weight (< 2.5 kg) (20%), Neonatal Hyperbilirubinemia (17%), Maternal risk factors (GDM) (14%). Most neonates with prematurity failed the hearing test with significant p-value of 0.05. DP- OAE test can be successfully implemented as newborn hearing screening method, for early detection of hearing impairment to achieve the high quality standard of screening programs.

Abstract
AIM Analysis of newborn hearing screening (NBS) outcomes and proposing a modified strategy for better performance of NBS in developing world. DESIGN Descriptive (retrospective and prospective) study. METHODS A total of 8412 newborns/neonates were subjected to risk factor assessment followed by a set of subjective (behavioral audiometry: BoA) and objective (OAE: otoacoustic emissions, ABR: auditory brainstem-evoked responses) hearing-screening in different combinations. DPOAE (primary objective tool) was undertaken in 2565 cases. Predictive value of risk factors on deafness was statistically analysed along with affectivity of objective, subjective and questionnaire-based screening tools. RESULTS Amongst 8412 babies, 45.5% were 'at risk' (major 36.41%, minor 9.17%). The OAE was abnormal in 299 cases (11.6% of 2565 & 3.5% in 8412). The abnormal OAE rate in prospective cases was 3.5% while in retrospective cases that underwent initial screening with BoA was 41%. A significant correlation was seen with consanguinity, high blood pressure, NICU stay>5 days, low birth weight, neonatal jaundice, delayed birth cry, pre-mature status, birth asphyxia and maternal excessive vomiting, while regression models of OAE outcome (sensitivity 99%, accuracy 89%) revealed highest predictive value for the initial 3 factors. BoA-screening revealed a sensitivity of 72.6%, and negative predictive value of 42.4%. Also a perfect correlation was evident between OAE-ABR, OAE-BoA and ABR-BoA. CONCLUSION A subjective NBS screening through questionnaire-based-risk-assessment and modified-BoA followed by selective referral for objective assessment is more practical and focussed approach for poor resourced countries that is likely to screen a larger population.

Abstract
Objective To estimate the prevalence of hearing loss and identify the high-risk factors among neonates with hearing loss. Methods Retrospective study done on 1054 infants in a tertiary care centre in Eastern India from 2020 to 2021 and approved by the Institutional Ethics Committee. A two-step protocol is used for screening. In the well-nursed group, OAE and BOA were performed. In the case of REFER results for automated ABR following OAE evaluation in well-nursed babies, a detailed audiological evaluation was scheduled to be carried out using diagnostic ABR within one month of age. In the high-risk group, hearing screening includes OAE, BOA, and AABR evaluations. AABR evaluation was performed as a part of the screening protocol irrespective of the results of OAE screening as PASS or REFER. Results In our study among 1053 neonates screened, 375 were in the risk category, and 679 were without risk factors. The overall prevalence of hearing loss in neonates was 22.78 per 1000 screened neonates and 56 per 1000 among high-risk neonates. In the high-risk group, we were able to identify 4 cases of Auditory spectrum neuropathy disorder with the use of AABR during 1st step of screening. In multivariate regression analysis, the risk factors for hearing loss identified were NICU stay (OR = 3.6, 95% CI = 1.1-12.03) and Craniofacial anomalies (OR = 55.37, 95% CI = 16.48- 186.01). Conclusion Early neonatal screening helps in the detection, intervention, and rehabilitation of hearing loss. The use of AABR in risk infant screening enhanced the chance of detection of auditory spectrum neuropathy disorder (ASND) cases.

Abstract
The study estimated the prevalence of hearing impairment in high-risk neonates and effect of high-risk factors on the hearing. A hospital-based cross sectional study was conducted on 327 neonates with high-risk factors. All the high-risk babies were screened using TEOAE and AABR followed by diagnostic ABR testing. Six (2%) of high-risk neonates were found to have bilateral severe sensorineural hearing loss. Risk factors associated with hearing impairment include multiple risk factors of Preterm delivery, hyperbilirubinemia, congenital anomalies, neonatal sepsis, viral or bacterial infection, positive family history of hearing loss and prolonged NICU stay. Further, the inclusion of AABR along with TEOAE has been shown to be a useful tool in reducing false-positive rates and identifying hearing loss.

Abstract
The aim of the study was to find the association of various risk factors with permanent hearing impairment in infants. A case-control study was designed on 420 infants with permanent hearing impairment and normal hearing. The case control ratio was 1:1. Alternate sampling method was used for selecting the control group. Review of medical records and parent interview was done to collect the information of risk factors. Family history(adj. OR 7.5; 95% CI 3, 14; P = 0.000), Consanguinity (adj. OR: 4; 95% CI 2,4; P = 0.000), intra uterine infection (adj. OR 18, 95% CI: 2.3-126.5, P = 0.000), post natal infection (adj. OR 3, 95% CI: 1.3-5, P = 0.004), low Apgar score (adj.OR: 4.6, 95% CI: 1.3-15), craniofacial anomaly (OR-4.6, 95% CI: 1.4-9.5, P = 0.005) and low birth weight (adj. OR: 2.3, 95% CI: 1.2-3.8) were significantly associated with hearing impairment. Among the risk factors, intra uterine infection was having highest significant association with permanent hearing impairment. This is followed by family history, low Apgar score, craniofacial anomaly, consanguinity, post natal infection and low birth weight.

Abstract
Hearing impairment is most common congenital dissorder and undiagnosed hearing loss can cause disorder in speech, language with delay in social and emotional developments. Early detection of Hearing Impairment in Infants and too access the relationship between selected risk factor and hearing loss. Neonates age upto 15 days randomly selected from pediatric and obstetrics and gynaecology department, born during this period were screened by OAE before their discharge from the hospital and after stabilizing high risk neonates. Informed consent of neonates parent/guardian was obtained before babies were subjected to OAE. A total of 400 neonates were screened for hearing loss by otoacoustic emission. Out of that 18 (4.5%) neonates failed the test in initial screening and were asked for follow up screening. Two neonates were lost to follow up. Out of 16 neonates, 2 (12.5%) neonate failed the test on follow up screening by otoacoustic emission and was referred for BERA. Neonates were classified as low and high risk basis of risk factors present. Out of 76 neonates having high risk of hearing loss, 16 failed the test. Similarly out of 324 neonates with low risk of hearing loss, only one neonate failed the test. Chi square analysis has revealed highly significant results (p < 0.001). Late identification of hearing loss presents a significant public health concern. However, without screening, children with hearing loss are usually not identified until 2 years of age, which results in significant delays in voice communication, language communication, social, cognitive, and emotional development. In contrast, early recognition, and intervention prior to 3 months of historic period has a significant positive impact on development.

Abstract
Hearing is an important sense organ for human beings essential for speech, language and overall development. Universal neonatal hearing screening programmes are mandatory in many developed countries. In India out of 1000 neonates approximately 5-6 infants are diagnosed with hearing impairment but still universal neonatal hearing screening programme is in its infancy. To screen all neonates delivered at our centre in three years, with secondary objective of determining the significance of risk factors with neonatal hearing loss and to provide appropriate intervention following the detection of a permanent hearing impairment. It is a non-randomised prospective cohort study conducted at a tertiary care centre to screen all neonates born between Jan 2017 and Dec 2019 with 2 stage protocol using distortion product otoacoustic emission and auditory brainstem response. The study population was also divided into two groups, ''at risk'' and ''no risk'' groups to determine the significance of risk factors on neonatal hearing loss. Total 2676 neonates were screened, OAE referral rate was 1.53%. There was a 94.12% follow up. The incidence of hearing impairment was found to be 7 per 1000(In the "no risk" group, 2.9 per 1000 and in the "at risk" group, 41.38 per 1000). Statistically, a significant difference was found in the incidence of hearing impairment between the two groups (p < 0.05, chi-square Test). Hospital based universal hearing screening of new born before discharge is feasible at a tertiary care centre. A high incidence of 0.7% congenital hearing impairment warrants universal newborn hearing screening programme. Considering the limitations and infrastructure in India, we should at least employ screening for all high risk neonates.

[PMID: 34150585 PMCID: PMC8205201 DOI: 10.1007/s12070-021-02683-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 06/10/2021] [Indexed: 02/07/2023] Open
Abstract
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 3rd 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.

Abstract
Objective The aim of this study is to estimate the incidence of hearing loss in neonates at a tertiary referral center, to assess the associated risk factors in those identified with hearing loss and to explore the challenges of starting and continuing a universal neonatal hearing screening programme in a tertiary care hospital over a decade. Materials and Methods It is a cohort prospective observational study conducted from January 2008 to January 2018. Five thousand five hundred and forty neonates underwent screening for hearing loss, of which 2688 were well babies and 2854 babies had one or more risk factors causing hearing loss. Otoacoustic emissions (OAE) is employed as the first level of screening within one month of birth. Brainstem evoked response audiometry (BERA) is done at 3 months of gestational age for all the well babies who were referred on OAE testing and all the high risk babies irrespective of the result of the OAE screening. The High risk criteria are based on the set criteria by the Joint Committee on Infant Hearing (2007) and American Academy of Pediatrics (1994). Results In our study the incidence of hearing impairment is 5.41 per 1000 neonates screened. In well babies and at risk babies it is 1.49 and 9.11 per 1000 respectively.The common neonatal risk factors associated with hearing loss in our study are babies admitted to neonatal intensive care units (NICU), intrauterine growth retardation (IUGR), birth weight less than 1500 g, respiratory distress syndrome (RDS) and hyperbilirubinemia. Conclusion The incidence of hearing loss in our study is comparable to that reported in literature (Bachmann KR, ArvedsonJC (1998) Early identification and intervention for children who are hearing impaired. Pediatr Rev. 1998 May; Vol. 19. No.5. pp. 155-165. http://www.ncbi.nlm.nih.gov/pubmed/9584525 Accessed from May 1998, Nagapoornima P, Ramesh A, Srilakshmi, Rao S, Patricia PL, Gore M, et al.

No.3. pp 179-183. http://www.ncbi.nlm.nih.gov/pubmed/24277966 Accessed from Mar 2014). Hearing loss is more common in those babies with risk factors as reported in literature (Nagapoornima P, Ramesh A, Srilakshmi, Rao S, Patricia PL, Gore M, et al. Universal hearing screening. Indian J Pediatr. 2007 Jun 18; 74(6):545-9. http://www.ncbi.nlm.nih.gov/pubmed/21654001 Paul AK (2011) Early identification of hearing loss and centralized newborn hearing screening facility-the Cochin experience. Indian Pediatr. Vol. 48. No. 5. pp 355-359. Accessed from May 2011). Implementation of neonatal hearing screening program at a tertiary care hospital using a two tier system with OAE and BERA is a feasible but challenging service.

Abstract
Newborn hearing screening in India is gaining momentum and more programs are getting established every year. We need to know their performance levels, strengths and weaknesses to provide suggestions for building effective future programs. The study aimed to report the status of Newborn Hearing Screening (NHS) program in the state of Tamil Nadu, India. A questionnaire on "Newborn Hearing Screening Survey" was developed and sent to 80 sites with NHS facility all over Tamil Nadu, India. The information collected was subjected to descriptive statistical analyses. On a 95% return rate, private sector contribution towards NHS program are the highest and most of the private hospitals have outsourced the NHS program. In most of the sites, audiologists are incharge of the NHS program and carried out the NHS testing. The majority of sites (67.1%) follow selective screening such as high risk factors, doctor's referral and admission at NICU. The preferred testing was TEOAE in the screening program. NHS protocol was found to be variable at each site and for each patient. The time between second screening and diagnostic testing went up to 3-6 months. However, there is a lack of organized system for documenting the program outcome. The result of this study calls the need for wider implementation of UNHS and to introduce a centralised state or local reporting system for documenting and tracking the infants with hearing impairment.

Abstract
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.

Jain S, Singh S. Factors associated with deaf-mutism in children attending special schools of rural central India: A survey. J Family Med Prim Care 2020; 9:3256-3263. [PMID: 33102280 PMCID: PMC7567182 DOI: 10.4103/jfmpc.jfmpc_222_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 03/13/2020] [Accepted: 04/07/2020] [Indexed: 11/18/2022] Open
Abstract
Background: Effects of hearing loss on the development of a child's ability to learn, to communicate, and to socialize can be devastating. If no auditory rehabilitation is done by peri-lingual period, the child develops permanent speech problems. The cases included in this category will be those having hearing loss more than 90 dB in the better ear or total loss of hearing in both the ears. Brainstem Evoked Response Audiometry (BERA)/Auditory Brainstem response (ABR) has been established as the most reliable screening tool for hearing assessment in neonates. Objectives: To perform a questionnaire-based survey of parents of children attending special schools for deaf–mutism, to find out the major medical, socio-demographic, and health service-related risk factors for deaf–- mutism. To perform screening for all these children in special schools for deaf and mute to get the major cause leading to their deaf–mutism in a given rural area in central India. Methodology: A cross-sectional study was done with deaf and mute students from special schools. A questionnaire was used to assess any complications in the antenatal, perinatal, and postnatal period. Thorough otorhinolaryngologic clinical examination was carried out with special attention to branchial arch anomalies and BERA was done to evaluate the deafness in individual and appropriate response is mentioned. Result: This study concluded neonatal septicemia, prematurity, low birth weight, consanguinity, and birth asphyxia as the most common risk factor for deafness in children. In this study, waiting for improvement on behalf of parents and misguidance by doctors posed the most common additional risk factor for mutism. Financial constraint and taking the matter of lack of hearing lightly were the most important reasons, which forced parents to opt for special schools and their inability to utilize the benefit of the cochlear implant.

Abstract
Sensoryneuronal hearing loss (SNHL) is one type of hearing impairment. The incidence of hearing loss (HL) is 1-3 per 1000 births. Complementary therapies may be effective in addressing the maladies of infants with HL. The aim of this study was to assess the efficacy of foot reflexotherapy in an infant with SNHL. The patient was a 3-month-old infant with SNHL. Pretest and post-test for HL were conducted using an audiologic method (auditory brainstem responses) combined with behavioral audiometry. The subject was treated with foot reflexotherapy for 30 min per session four times per week for a period of 24 weeks. Foot reflexotherapy was effective in auditory recuperation of an infant with SNHL. The results of this novel study suggest that foot reflexotherapy can be an effective complementary treatment for infants with SNHL, especially for those 3 to 9 months of age.

Abstract
FAPCI is a parent/caregiver reporting questionnaire, which evaluates the communication performance of pre-school children with cochlear implants in the age range of 2-5 years, using behavioral examples of children's daily activities. Tools for the objective and effective measurement of communication for cochlear implanted Indian children in Hindi language are lacking. The primary aim of the study was to adapt American English version of FAPCI into the Hindi language. With a secondary aim to find out the communication functioning of Cochlear implanted children by administering FAPCI (HN) and comparing the findings with children with normal hearing. The FAPCI was translated to Hindi using the forward-backward procedure. The FAPCI (HN) was then administered to the parents of children with NH (n = 35) and CI (n = 44), 2-9 years of age. Internal consistency was checked using Cronbach's alpha. Other statistical analysis included Bartlett's test of sphericity, factor loading, Wilcoxon test and t test. During adaptation few items were modified and one item was removed which contained "inversion question" not used in Hindi language. The Hindi version of FAPCI showed excellent internal consistency (Cronbach's alpha > 0.90). The split-half coefficient for the first half of the data was equal to 0.96 and for the second half was equal to 0.95. The CI group had significantly lower FAPCI scores (61.14 ± 21.49) than the NH group (101.43 ± 9.24) (p < 0.05, Wilcoxon test). FAPCI-Hindi can be used to measure the communicative functioning of cochlear implanted children in Indian population and results may be used as a guideline to revise the speech and language therapy plans to maximize the cochlear implant benefits.

Abstract
Hearing loss can have a devastating impact on the cognitive development and psychological well-being of children and their families. Newborn hearing screening should be given special attention especially in a country like ours where the burden of this disability is heavy. Screening all newborns irrespective of risk factors helps in better detection, and hence further management can be initiated at appropriate time. To implement newborn hearing screening at Vanivilas hospital and to estimate the incidence of hearing loss among the high risk groups. To create awareness about the need for detecting childhood deafness among parents and general population. To develop a centre of excellence for evaluation, intervention and rehabilitation for hearing impaired in a tertiary care hospital. Prospective study. All neonates born in Vanivilas Hospital attached to Bangalore Medical College and Research Institute underwent hearing screening using four stage protocols with otoacoustic emission (OAE) tests and final confirmation with Brainstem evoked response audiometry (BERA) tests. May 2015-May 2017. Number of newborns screened were 26,487, and 19 (0.717/1000) newborns were detected to have hearing impairment. The incidence of hearing loss among high risk group was 0.188/1000, and among the non risk group was 0.528/1000. Newborn hearing screening must be made mandatory and multi-staged protocol based screening for hearing loss should be implemented. This will make newborn screening programme more efficient and also will help in initiating treatment at an early stage so that further damage can be prevented.

Abstract
PURPOSE To explore the correlation between hearing and speech recovery levels after cochlear implantation and examined the preoperative microstructure of auditory pathways and speech centre using DTI. METHODS (1) Fifty-two SNHL children between 0 and 6 years and 19 age and gender matched normal hearing subjects had received 3.0 T-MRI examination of the brain.FA, axial diffusion coefficient (λ‖), radial diffusion coefficient (λ⊥), and MD values in the lateral lemniscus, inferior colliculus, medial geniculate bodies, auditory radiations, Brodmann areas 41, 42, 22, 44, 45, and 39 were all measured bilaterally. (2) CAP and SIR scores were assessed in fourty-six cochlear implantation children at 6 months post-implant. Correlations among deaf children ages, FA value of bilateral inferior colliculus FA values, BA22, BA44, and postoperative CAP, and SIR scores were analyzed using multiple linear regression. RESULTS The preoperative standard partial regression age coefficient of deaf children (|bi'| = 0.404) was slightly greater than that of the inferior colliculus (|bi'| = 0.377) FA value. CONCLUSION Preoperative children ages and inferior colliculus FA values were important factors influencing postoperative CAP score. Inferior colliculus FA value is a vital influencing factor in rehabilitation after cochlear implantation.

Implementation and evaluation of a rural community-based pediatric hearing screening program integrating in-person and tele-diagnostic auditory brainstem response (ABR).

Abstract
BACKGROUND In an attempt to reach remote rural areas, this study explores a community-based, pediatric hearing screening program in villages, integrating two models of diagnostic ABR testing; one using a tele-medicine approach and the other a traditional in-person testing at a tertiary care hospital. METHODS Village health workers (VHWs) underwent a five day training program on conducting Distortion Product Oto Acoustic Emissions (DPOAE) screening and assisting in tele-ABR. VHWs conducted DPOAE screening in 91 villages and hamlets in two administrative units (blocks) of a district in South India. A two-step DPOAE screening was carried out by VHWs in the homes of infants and children under five years of age in the selected villages. Those with 'refer' results in 2nd screening were recommended for a follow-up diagnostic ABR testing in person (Group A) at the tertiary care hospital or via tele-medicine (Group B). The overall outcome of the community-based hearing screening program was analyzed with respect to coverage, refer rate, follow-up rate for 2nd screenings and diagnostic testing. A comparison of the outcomes of tele-versus in-person diagnostic ABR follow-up was carried out. RESULTS Six VHWs who fulfilled the post training evaluation criteria were recruited for the screening program. VHWs screened 1335 children in Group A and 1480 children in Group B. The refer rate for 2nd screening was very low (0.8%); the follow-up rate for 2nd screening was between 80 and 97% across the different age groups. Integration of tele-ABR resulted in 11% improvement in follow-up compared to in-person ABR at a tertiary care hospital. CONCLUSIONS Non-availability of audiologists and limited infrastructure in rural areas has prevented the establishment of large scale hearing screening programs. In existing programs, considerable challenges with respect to follow-up for diagnostic testing was reported, due to patients being submitted to traveling long distance to access services and potential wage losses during that time. In this program model, integration of a tele-ABR diagnostic follow-up improved follow-up in comparison to in-person follow-up. VHWs were successfully trained to conduct accurate screenings in rural communities. The very low refer rate, and improved follow-up rate reflect the success of this community-based hearing screening program.

Abstract
Hearing is one of the most important sense organs for man. Hearing loss is often associated with delayed speech and language development in young children. Early identification and intervention improves the chance a child gets to lesser delays in development and improving the overall quality of life. To find out the prevalence of hearing loss in neonates in the rural taluka of Maval, Pune, Maharashtra, India. Prospective Non Randomized Clinical Study. The study was carried out between April 2012 and April 2015. A total of 8192 babies were screened across various centers around the Maval area. The babies who had some high risk factors were 1683 in number and babies who had no high risk factors i.e. well babies were 6509. In our study, the overall prevalence of hearing loss in neonates in Maval taluka of Maharashtra was found to be 3.54 per 1000 live births, in normal born neonates (well babies) was 1.689 per 1000 births, in high risk babies was 10.69 per 1000 high risk births. The prevalence of low birth weight neonates, hyperbilirubinemia neonates and neonates with craniofacial abnormalities developing hearing impairment was found to be 5.9, 3.56 and 1.18 per 1000 high risk births respectively. India is the second most populated country in the world with nearly a fifth of the world's population. There is a need for the universal neonatal screening for deafness for earlier detection of deafness and rehabilitation. Level of Evidence: Level IV.

Abstract
OBJECTIVE Prelingual deafness in children demands urgent action as best outcome is dependent on earliest possible diagnosis and intervention. Objective of this study was to determine age of suspicion, diagnosis, intervention, and outcome in a representative group of deaf children in West Bengal, India, and suggest ways of improving these parameters. METHODS In this cross-sectional study, ages of suspicion, diagnosis, intervention and outcome of 303 randomly selected deaf children were elicited from a cohort of 1316 children with deafness identified in an earlier study. RESULTS Median ages of suspicion, diagnosis and amplification were 18, 72 and 84 months respectively. Age of suspicion was significantly related to parental education (p < 0.05); age of diagnosis to parental education and socio-economic status (p < 0.001) and children's geographic location (p < 0.01). Following diagnosis, 86% of children received hearing aids but only 6% used their aids consistently; 86% were non-verbal, 12% could communicate with a mixture of speech and gesture and only 2% with speech alone. CONCLUSION Current situation of deaf children in West Bengal, and evidence indicates, in much of India, is insupportable. However, widely diverse socio-economic conditions and scarcity of public health infrastructure preclude one solution of the problem for the whole country. In absence of the ideal universal newborn hearing screening, rigorously monitored and costed pilot programs of different models of early detection and intervention using newborn hearing screening, targeted screening and trial of calibrated noisemakers by primary care workers should be tried to see which works best where, so that successful programs can be scaled up over time.

Abstract
The objectives were to determine the incidence of hearing impairment in a standardized population of neonates and to determine the significance of association of epidemiological and risk factors with neonatal hearing loss. A cohort of 600 newborns was selected for study and divided into two groups-525 in 'No Risk' group and remaining 75 in 'At Risk' group. The study protocol was carried out in three steps: (a) Screening of Hearing Loss with TOAE, done from 36 h after birth to 28 days of life, (b) Re-screening of hearing loss in newborns (of 4-12 weeks of age), who were tested positive for hearing loss in the first screening, done with DPOAE, (c) Confirmation of hearing loss with BERA, in those who were tested positive in both the first and second screening. In the study the incidence of hearing impairment in 600 infants screened was 6.67 per 1000 screened; 3.81 per 1000 screened in the Not at Risk group and 26.67 per 1000 screened in At Risk group. In At Risk group, admitted to the NICU, severe birth asphyxia and hyperbilirubinemia were found to be major risk factors. Loss to follow up was more in Not at Risk group and False Positive cases with TEOAE were more than DPOAE. BERA was found to be must for confirmation of hearing loss. Neonatal Hearing Screening of only At Risk population is likely to miss some hearing loss. Universal Hearing Screening should be the preferred strategy. Good follow up in the 'At Risk' group suggests that initial interventions in NICU had sensitized the parents for the possibility of hearing loss. This study recommends the introduction of two stage neonatal screening-rescreening protocol, using OAE and BERA, in the country in phased manner.

Abstract
Hearing loss is hidden disability and second most common congenital pathology. Prevention, early identification and early intervention of hearing loss can prevent further disability in development of speech, language, cognition and other developmental domains. The prevalence of congenital hearing loss has been estimated to be 1.2-5.7 per thousand in neonates. In these contexts, the aim of study was to determine outcomes of neonates hearing screening program in Hospital. It is a clinical cross-sectional study which was conducted in tertiary care centre from 8th July, 2015 to 31th May, 2016. Total no of 2254 cases were screened. Details case history including high risk register, Pediatric Audiometry, Otoacoustic Emission tests were performed followed brainstem evoked response audiometry. The Prevalence of hearing loss among high risk babies confirmation by BERA was 8.8% per 1000 babies and 16 cases were recommended for Cochlear Implant. The screening protocol with objective test i.e. Distortion Product Otoacoustic Emission and confirmation by Brainstem Evoked Response Audiometry is very useful tool in early identification of congenital hearing loss in neonates. Hence, the results of this study will be used to initiate universal newborn hearing screening in other hospitals. Moreover, this study highlights the relevance of neonatal hearing screening in other states of India and country where this screening is not performed routinely in all hospitals and creating awareness to identify neonatal risk factors associated with hearing loss and understand the importance of early identification and early intervention and among health care professionals.

Abstract
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.

Abstract
INTRODUCTION The support provided and the decisions taken by mothers determine the success of Universal Newborn Hearing Screening (UNHS). Attempts at exploring the existing knowledge-attitude among mothers is crucial to create/modify the existing screening programs. The present study attempts to explore the knowledge and attitude toward infant hearing loss (HL) among mothers of newborns in the Indian state of Karnataka. METHOD A cross-sectional survey was conducted among 219 mothers of newborns in Karnataka, India. The questionnaire was framed from existing literature and consisted of 19 questions assessing knowledge and attitude toward infant HL to be rated on a three-point scale (no, not sure, yes). Descriptive statistics and Cronbach's α were used to analyze the data. RESULTS Mothers exhibited good knowledge of risk factors; noise (70.3%) and ear discharge (54.3%). More than 75% agreed that treatment for HL is available and that these children can attend school. The questions of superstitions and cultural beliefs yielded mixed responses. A large number of mothers expressed desire to have their children tested at birth (84.9%) and were concerned about their children's hearing (87.7%). Yet only 54.3% stated that they would allow their children to wear hearing aids. SUMMARY AND CONCLUSION The present study is an attempt to understand the knowledge and attitude of mothers toward infant HL in Karnataka and facilitate identification of potential areas of less knowledge as a reference for endeavors of enhancement. It further highlights the need for implementing public awareness programs to improve knowledge and attitude of mothers toward infant HL for better implementation of UNHS.

Abstract
Deafness is the most common curable childhood handicap. It is a well recognised fact that unidentified hearing impairment can adversely affect optimal speech and language development and therefore academic, social and emotional development. Universal neonatal hearing screening programmes are implemented in many developed countries. However it is still in its early stage in India. The incidence of hearing impairment in India is 1-6 per thousand newborns screened (Paediatrics 19:155-165, 1998; Indian J Paediatr 74(6):545-549, 2007; Status of Disability in India, pp 172-185 2000). To determine the incidence of permanent hearing loss of moderate to evere variety in neonates taking care in a tertiary care rural based hospital in Gujarat. It was a non randomised observational study done for duration of 3 years. All neonates born in Shri Krishna Hospital underwent screening using two stage protocols with DPOAE test and final confirmation done with BERA. Total 2534 neonates were screened out of them 52 failed and 2482 (97.94 %) neonates passed in the 1st DPOAE test with 2.05 % refer rate. Total 7 (2 per 1000) neonates were detected with hearing impairment. 10 % neonates had one or other high risk factor. Out of high risk neonates, 1.8 % were diagnosed with hearing impairment in high risk group. Overall the follow-up rate was 72.7 %. Hospital based universal hearing screening of new born before discharge is feasible at a rural based tertiary care centre. Non specialist staff is invaluable in achieving a satisfactory referral rate with two stage hearing screening protocol. However, more efficacious tracking and follow up system is needed to improve the follow up rate for diagnosis.

Abstract
Loss or impairment of auditory sense is the most prevalent deficit of all the sensory organs. With virtually no mortality, hearing impairment causes huge impact on one's social, educational and economic well-being. There are 5-6 infants who are hard of hearing out of 1000 neonates. They will not be identified till they attain 2 or more years of age, by then irreversible damage would have been done. Universal screening for hearing of new-borns is the only way to decrease the burden of deafness in our society. There are tools available which can be administered by health workers after initial training for screening the infants for hearing impairment. Under the aegis of National Programme for Prevention and Control of Deafness (NPPCD) of India universal screening can and should be applied. The programme would entail additional financial burden for the initial purchase of screening machines and rehabilitating the identified children.

Abstract
OBJECTIVES To report experience of implementing universal newborn hearing screening (UNHS) in a tertiary care neonatal unit, identify risk factors associated with failed two-step automated acoustic brainstem response (AABR) screen and evaluate cost of AABR. METHODS This was a prospective study of UNHS outcomes of all live births with two step AABR using BERAphone MB11®. Outcome measures were screening coverage, refer, pass and lost to follow up rates and cost of AABR using micro-costing method. To identify risk factors for failed screening, authors performed multivariate logistic regression with failed two-step AABR screen as dependent variable and baseline risk factors significant on univariate analysis as predictors. RESULTS Screening coverage was moderate (84 %), with 2265 of total 2700 eligible infants screened with initial AABR (mean gestation 37.2 ± 2.3 wk; birth weight 2694 ± 588 g; 305 received nursery care). A total of 273 of 2265 infants were "refer" on first screen. Second screen was done on 233, of which 58 were "refer". Of these, 35 underwent conventional ABR, of which 5 were diagnosed to have hearing impairment. Only 2 could get hearing aid. Overall, a total of 2197 (81.4 %) infants passed, 496 (18.4 %; excluding 2 deaths) were lost to follow up at various stages, and 5 (0.2 %) were diagnosed with hearing impairment, all of whom were high risk. Average cost of AABR was INR 276 per test. No factor emerged as significant on multivariate analysis. CONCLUSIONS UNHS is feasible to implement, but significant lost to follow up and non-linkage with appropriate rehabilitation services limit its utility. Cost effectiveness of UNHS compared to high risk based screening needs to be determined.

Abstract
Background To screen the newborn by Transient evoked Otoacoustic emission and to assess the incidence of hearing damage and associated risk factors. Method This longitudinal prospective observational study was conducted at a tertiary care hospital in India. A total of 415 babies were included in the study. All the newborns were evaluated with Transient evoked Otoacoustic emission (TEOAE) which was done by age of 1–3 days. Auditory brain stem response audiometry (AABR) was performed at the age of three months for confirming the hearing loss in the neonates those who failed the TEOAE screening. For infants proven to have significant hearing loss in one or both ears, were denoted to an ear, nose, and throat specialist for further evaluation & rehabilitation. Results Out of total 415 babies included in the study, 22 neonates showed abnormal TEOAE examination. Out of these 22 neonates, hearing loss was confirmed in 18 (82 %) subjects. by AABR. The following antenatal and post-natal risk factors were associated with hearing loss: ante-partum bleeding, history of maternal blood transfusion, fetal distress, prematurity, severe birth asphyxia, NICU admission for more than 24 h and Apgar score less than five at 5 min. Conclusion Late identification of hearing loss presents a substantial public health burden. Early recognition and intervention prior to 6 months of age has a significant positive impact on development. A high incidence of hearing impairment seen in our study neonatal population warrants the urgent implementation of universal hearing screening of all the newborn infants in India. NICU infants admitted for more than 24 h are to have an auditory brainstem response (AABR) included as part of their screening so that neural hearing loss will not be missed.

Abstract
After a review of the current health scene in India, the authors suggest that the Government of India should consider seriously, the introduction of new born screening. As a first step, a central advisory committee should be constituted to recommend what is required to be done to strengthen the infrastructure and the manpower to carry out new born screening, and the disorders to be screened. In the urban hospitals newborn screening (NBS) for three disorders can be easily introduced (congenital hypothyroidism, congenital adrenal hyperplasia and G-6-PD deficiency), while in the rural areas this should begin with congenital hypothyroidism, especially in the sub Himalayan areas. Concurrently, logistic issues regarding diets and special therapies for inborn errors of metabolism should be sorted out, laboratories to confirm the diagnosis should be set up, and a cadre of metabolic physicians should be build up to treat those identified to have inborn errors of metabolism. Once these are established on a firm footing, tandem mass spectrometry should be introduced as it allows the identification of a number of disorders in an affordable manner. The recent improvements and current trends in health care in India have created the necessary infrastructure for adopting NBS for the benefit of infants in India.

Abstract
Parents of children with hearing impairment are at increased risk of mental health morbidities. We examined the predictive factors associated with caregiver's strain and psychological morbidities in parents and family caregivers of children with hearing impairment. In total, n = 201 parents and family caregivers of children with and without hearing impairment aged 3 to 16 years were recruited. Caregiver's strain and psychological morbidities were measured using the Zarit Burden scale and the World Health Organization's Self-Reporting Questionnaire (SRQ-20). Presence of behavioural problems in children was measured using the Strengths and Difficulties Questionnaire. After adjustment, low educational attainment and domestic violence were found to be associated with caregiving strain, whereas dissatisfaction with social support from family, behavioural problems in children, and domestic violence strongly predicted psychological morbidities. Addressing the mental healthcare needs of parents may help in downsizing the impact of psychological morbidities on the well-being of children with hearing impairment.

Abstract
A study was conducted to determine why there was a delay in detection of hearing loss in congenitally hearing impaired children in rural India. It was found that although the parents of these children visited a primary care physician, relevant information regarding investigation and rehabilitation of hearing loss was not available to the patient. In the absence of a universal hearing screening programme in this country, it is a matter of importance to strengthen this aspect of community otolaryngology in the undergraduate ENT programme. There is also a need for continuing medical education programmes for primary care physicians regarding available methods of investigation and rehabilitation for a hearing impaired person.

Abstract
OBJECTIVE To implement a neonatal hearing screening program using automated auditory brainstem response audiometry in a tertiary care set-up and assess the prevalence of neonatal hearing loss. DESIGN Descriptive study. SETTING Tertiary care hospital in Southern India. PARTICIPANTS 9448 babies born in the hospital over a period of 11 months. INTERVENTION The neonates were subjected to a two stage sequential screening using the BERAphone. Neonates suspected of hearing loss underwent confirmatory testing using auditory steady state response audiometry. In addition, serological testing for TORCH infections, and connexin 26 gene was done. MAIN OUTCOME MEASURES Feasibility of the screening program, prevalence of neonatal hearing loss and risk factors found in association with neonatal hearing loss. RESULTS 164 babies were identified as suspected for hearing loss, but of which, only 58 visited the audiovestibular clinic. Among 45 babies who had confirmatory testing, 39 were confirmed to have hearing loss and were rehabilitated appropriately. 30 babies had one or more risk factors; 6 had evidence of TORCH infection and 1 had connexin 26 gene mutation. CONCLUSION Neonatal hearing screening using BERAphone is a feasible service. The estimated prevalence of confirmed hearing loss was comparable to that in literature. Overcoming the large numbers of loss to follow-up proves to be a challenge in the implementation of such a program.

Abstract
UNLABELLED Deafness is commonest curable childhood handicap. Most remedies and programmes don't address this issue at childhood level leading to detrimental impact on development of newborns. Aims and objectives are (A) screen all newborns for deafness and detect prevalence of deafness in children less than 2 years of age. and (B) assess efficacy of multi-staged OAE/ABR protocol for hearing screening. METHODOLOGY Non-randomized, prospective study from August 2008 to August 2011. All infants underwent a series of oto-acoustic emission (OAE) and final confirmatory auditory brainstem evoked response (ABR) audiometry. Finally, out of 1,101 children, 1,069 children passed the test while 12 children had impaired hearing after final testing, confirmed by ABR. Positive predictive value of OAE after multiple test increased to 100 %. OAE-ABR test series is effective in screening neonates and multiple tests reduce economic burden. High risk screening will miss nearly 50 % deaf children, thus universal screening is indispensable in picking early deafness.

Abstract
OBJECTIVE To identify the perception of the train passengers about the cause and the management of hearing loss. METHODOLOGY A total of 115 passengers, 90 males and 25 females, in the age range of 13-80 years (mean: 39.19, standard deviation: 15.4) years. RESULTS From the survey, it is found that most of the participants (82.6%) had seen a person with hearing loss. Among them, 10 reported to have relatives who have hearing loss but did not know where they should be taken for remedy. Seventeen individuals (all geriatric) were suspected to be having reduced hearing acuity during the survey. However, none of them admitted to be having a significant disability due to hearing loss. Also 48% of the participants correctly attribute hearing loss to biological and environmental causes (genetic, congenital and noise induced causes) and three percent of them attributed it to myth revealing that most of the participants had awareness about what could cause hearing impairment. Regarding management, most of the participants (25.2%) agreed to medical treatment as the best, followed by hearing aids (23.5%). There were no myths related to management. Five of the participants interviewed, were already undergoing medical treatments from various medical institutions for their hearing impairment, but reported to have no benefit from the treatment. Among the participants who answered yes to question 4, most of them recognized Speech Language Pathologists as professionals who could manage speech difficulties but mostly attributed management of hearing impairment to an Ear Nose and Throat (ENT) specialist. CONCLUSIONS An awareness pamphlet targeting the myths can be distributed on train, role of an audiologist as a hearing professional can also be targeted in the pamphlets, language used in the advertisements and pamphlets should be culture and region specific, pictorial representation could be a better idea, the need for a healthy and comfortable communication has to be explained especially to the adults and geriatric population and the elderly persons must have both, the skills and the motivation to communicate in the external environment which must be conducive for communication.

Abstract
OBJECTIVE Hearing impairment in children across the world constitutes a particularly serious obstacle to their optimal development and education, including language acquisition. Around 0.5-6 in every 1000 neonates and infants have congenital or early childhood onset sensorineural deafness or severe-to-profound hearing impairment, with significant consequences. Therefore, early detection is a vitally important element in providing appropriate support for deaf and hearing-impaired babies that will help them enjoy equal opportunities in society alongside all other children. This analysis estimates the costs and effectiveness of various interventions to screen infants at risk of hearing impairment. METHODS The economic analysis used a decision tree approach to determine the cost-effectiveness of newborn hearing screening strategies. Two unique models were built to capture different strategic screening decisions. Firstly, the cost-effectiveness of universal newborn hearing screening (UNHS) was compared to selective screening of newborns with risk factors. Secondly, the cost-effectiveness of providing a one-stage screening process vs. a two-stage screening process was investigated. RESULTS Two countries, the United Kingdom and India, were used as case studies to illustrate the likely cost outcomes associated with the various strategies to diagnose hearing loss in infants. In the UK, the universal strategy incurs a further cost of approximately £2.3 million but detected an extra 63 cases. An incremental cost per case detected of £36,181 was estimated. The estimated economic burden was substantially higher in India when adopting a universal strategy due to the higher baseline prevalence of hearing loss. The one-stage screening strategy accumulated an additional 13,480 and 13,432 extra cases of false-positives, in the UK and India respectively when compared to a two-stage screening strategy. This represented increased costs by approximately £1.3 million and INR 34.6 million. CONCLUSIONS The cost-effectiveness of a screening intervention was largely dependent upon two key factors. As would be expected, the cost (per patient) of the intervention drives the model substantially, with higher costs leading to higher cost-effectiveness ratios. Likewise, the baseline prevalence (risk) of hearing impairment also affected the results. In scenarios where the baseline risk was low, the intervention was less likely to be cost-effective compared to when the baseline risk was high.

Abstract
Significant hearing loss is one of the most common major abnormalities present at birth. If undetected, it will impede speech, language and cognitive development. Significant bilateral hearing loss is present in 1 to 3 per 1000 new born infants in the well-baby nursery population and in 2 to 4 per 100 infants in the intensive care unit population. It is an established fact that if hearing loss is present it should be detected and remediated before the baby is 6 months old. Neither universal screening nor a high risk screening, exists in majority of the hospitals in our country. In such a situation, a centralized facility catering to all hospitals in the city is a practical option. A two-stage screening protocol is projected, in which infants are screened first with otoacoustic emissions (OAE). Infants who fail the OAE are screened with auditory brainstem response (ABR). This two tier screening program (the second tier being ABR, which is more expensive) is required only for a selected few, making the program more practical and viable. It is the practicability of this program that makes it relevant for replication in other cities of the country, making it a model screening program for any developing country.

Abstract
OBJECTIVES The present study is aimed at figuring out the status of new-born hearing screening program being conducted in India, estimate the use of different screening instruments used and tests practiced, study the role of various professionals involved and document the current practices of audiologists in the country. METHOD A questionnaire on "Newborn Hearing Screening Survey" was sent to 185 institutions (165 medical colleges and 20 Speech and hearing centers) all over India and the information gathered was subjected to appropriate analyses. RESULTS On a 16.75% return rate of the questionnaire, almost half of the colleges have their annual birthing census more than 2000. The majority of sites (57.13%) report an average length of stay for a vaginal delivery to be more than 24 hours with 78.94% also reporting of a NICU of Level II/III type. Only 38.09% of the medical colleges have a universal Newborn Hearing screening program (NBHS) in comparison to 80% of the Speech and Hearing centers. Again 43.8% of the medical colleges who conduct NBHS program have an audiologist and majority of them work towards screening. Almost 63% of the speech and hearing centers use physiological tests like ABR, OAE or their combination to screen newborns. Both medical and speech and hearing organizations prefer that the audiologist inform and even give a written material regarding the results of the tests to the parents. Only 62.65% of the institutions refer less than 11% of their clients for further testing at the time of discharge. In 50% of the medical colleges the results of a test are reported to the parents and primary care physicians/doctors and in 37.5% of the speech and hearing centers the results are informed to the parents. CONCLUSIONS While keeping in mind the incidence of hearing impairment in the neonatal population of India, the results of this survey warrant the need for an urgent implementation of universal neonatal hearing screening in all the health care facilities in the country, at large.

Abstract
The universal newborn hearing screening (UNHS) is currently spreading in Germany, as well, even though there can be no talk of a comprehensive establishment. The introduction of UNHS in several federal states such as Hamburg, Hessen, and Schleswig-Holstein can be ascribed to the personal commitment of individual pediatric audiologists. Apart from the procurement of the screening equipment and the training of the staff responsible for the examination of the newborns, the tracking, i.e. the follow-up on children with conspicuous test results, is of utmost importance. This involves significant administration effort and work and is subject to data protection laws that can differ substantially between the various federal states. Among audiologists, there is consensus that within the first three months of a child's life, a hearing loss must be diagnosed and that between the age of 3 and 6 months, the supply of a hearing aid must have been initiated. For this purpose, screening steps 1 (usually a TEOAE measurement) and 2 (AABR testing) need to be conducted in the maternity hospital. The follow-up of step 1 then comprises the repetition of the TEOAE- and AABR measurement for conspicuous children by a specialized physician. The follow-up of step 2 comprises the confirmatory diagnostics in a pediatric audiological center. This always implies BERA diagnostics during spontaneous sleep or under sedation. The subsequent early supply of a hearing aid should generally be conducted by a (pediatric) acoustician specialized on children.

Abstract
OBJECTIVE To examine the effectiveness and cost of implementing a noise reduction protocol in a level III neonatal intensive care unit (NICU). METHODS A prospective longitudinal study was done in a level III NICU, wherein a noise reduction protocol that included behavioral and environmental modification was implemented. The noise levels were measured sequentially every hour for 15 days before and after this intervention. The statistical significance of the reduction in noise levels after implementation of the protocol was tested by paired sample student's t-test. Cost was calculated using the generalized cost effectiveness model of the World Health Organisation. The present study has 80% power with 95% confidence to measure 2 dB differences between groups for the maximum recommended of 50 dB. RESULTS The protocol in the present study reduced noise levels in all the rooms of the NICU to within 60 dB with high statistical significance (p< 0.001). The extent of noise reduction in the rooms of the NICU was as follows: ventilator room by 9.58 dB (95% confidence interval: 6.73-12.42, p < 0.001), stable room by 6.54 dB (95% confidence interval: 2.92-4.16, p < 0.001), isolation room by 2.26 dB (95% confidence interval: 1.21-3.30, p < 0.001), pre-term room by 2.37 dB(95% confidence interval: 1.22-3.51, p < 0.001) and extreme preterm room by 2.09 dB (95% confidence interval: 1.14-3.02, p < 0.001). The intervention was most cost-effective in the ventilator room, requiring Rs. 81.09 to reduce 1 dB and least effective in the extreme pre-term room requiring Rs. 371.61 to reduce 1 dB. CONCLUSION The high efficacy and affordability of noise reduction protocols justify the need for implementation of these measures as a standard of care in neonatal intensive care units.

Abstract
OBJECTIVE To determine the feasibility and effectiveness of hospital-based universal newborn hearing screening programme for the early detection of permanent congenital or early-onset hearing loss (PCEHL) in Lagos, Nigeria. METHODS A cross-sectional pilot study based on a two-stage universal newborn hearing screening by non-specialist health workers using transient evoked otoacoustic emissions (TEOAE) and automated auditory brainstem-response (AABR) in an inner-city maternity hospital over a consecutive period of 40 weeks. The main outcome measures were the practicality of screening by non-specialist staff with minimal training, functionality of screening instruments in an inner-city environment, screening coverage, referral rate, return rate for diagnosis, yield of PCEHL and average age of PCEHL confirmation. RESULTS Universal hearing screening of newborns by non-specialist staff without prior audiological experience is feasible in an inner-city environment in Lagos after a training period of two-weeks. Notwithstanding excessive ambient noise within and outside the wards, it was possible to identify a test site for TEOAE screening within the hospital. The screening coverage was 98.7% (1330/1347) of all eligible newborns and the mean age of screening was 2.6 days. Forty-four babies out of the 1274 who completed the two-stage screening were referred yielding a referral rate of 3.5%. Only 16% (7/44) of babies scheduled for diagnostic evaluation returned and all were confirmed with hearing loss resulting in an incidence of 5.5 (7/1274) per 1000 live births or a programme yield of 5.3 (7/1330) per 1000. Six infants had bilateral hearing loss and the degree was severe (> or =70 dB nHL) in three infants, moderate (40 dB nHL) in one infant and mild (<40 dB nHL) in two infants. The age at diagnosis ranged from 46 days to 360 days and only two infants were diagnosed within 90 days. CONCLUSIONS Hospital-based universal hearing screening of newborns before discharge is feasible in Nigeria. Non-specialist staff are valuable in achieving a satisfactory referral rate with a two-stage screening protocol. However, a more efficient tracking and follow-up system is needed to improve the return rate for diagnosis and age of confirmation of hearing loss.
