Audit of the Southern DHB B4 School hearing screening referral process: is there unmet need?

The B4 School Check aims for early detection and appropriate management of hearing loss prior to school entry. In light of increasing awareness of inequitable health outcomes across a variety of measures in Aotearoa New Zealand, particularly for Māori and Pasifika, we performed an audit of B4 School screening hearing related referrals. For the census year 2018, we examined the hearing screening data for age, gender, ethnicity, region and locality. For those children whose screening triggered a referral, the district health board (DHB) record was examined to assess whether a referral was received by the public audiology or otolaryngology head and neck surgery (ORLHNS) departments and if any appointment was subsequently attended. For Otago, but not Southland, there was a mismatch between census and screening programme estimates of the number of children eligible for screening. Māori and Pasifika children were significantly less likely to pass the screening tests (p<0.00001) compared to other ethnicities. Referral rates were not significantly different among ethnic groups, but Pasifika children were significantly less likely be assessed by an audiologist or otolaryngologist (p<0.004). Despite an equal distribution of screening and referral, significantly more Māori and Pasifika children will start primary school with potential hearing impairment compared to other ethnicities. While the Southern DHB B4 School hearing screening programme is equal in capturing children of different backgrounds, it demonstrates a greater prevalence of potential hearing impairment among Māori and Pasifika children when entering primary school. This raises the need to consider how to better provide ongoing care for these children.

Effectiveness of universal newborn hearing screening: A systematic review and meta-analysis.

BackgroundPermanent bilateral hearing loss (PBHL) is a serious condition in newborns, with a prevalence of at least one per 1000 live births. However, there has been no recent systematic review and meta-analysis of the effectiveness of universal newborn hearing screening programs (UNHS).MethodsWe registered our study protocol on PROSPERO CRD42020175451. Primary outcomes were any identification of PBHL (ie, PBHL diagnosed at any time), age of identification of PBHL, and neurodevelopment. Two reviewers searched standard databases to March 2022 and extracted data. We used fixed and random effects meta-analysis to pool data and graded the certainty of evidence using standard methods.ResultsThe search retrieved 2834 records. We identified five studies reporting on the effects of UNHS vs no UNHS in 1 023 610 newborns. The relative risk of being identified with PBHL before nine months in infants with UNHS compared to infants without UNHS was 3.28 (95% confidence interval (95% CI) = 1.84, 5.85, one study, 1 023 497 newborns, low certainty evidence). The mean difference in the age of identification of PBHL in infants with UNHS compared to infants without UNHS was 13.2 months earlier (95% CI = -26.3, -0.01, two studies, 197 newborns, very low certainty evidence). The relative risk of infants eventually being identified with PBHL in infants with UNHS compared to infants without UNHS was 1.01 (95% CI = 0.89, 1.14, three studies, 1 023 497 newborns, low certainty evidence). At the latest follow-up at 3-8 years, the standardised mean difference (SMD) in receptive language development between infants with UNHS compared to infants without UNHS was 0.60 z scores (95% CI = 0.07, 1.13, one study, 101 children, low certainty evidence) and the mean difference in developmental quotients was 7.72 (95% CI = -0.03, 15.47, three studies, 334 children, very low certainty evidence). The SMD in expressive language development was 0.39 z scores (95% CI = -0.20, 0.97, one study, 87 children, low certainty evidence) and the mean difference in developmental quotients was 10.10 scores (95% CI = 1.47, 18.73, 3 studies, 334 children, very low certainty evidence).ConclusionsUNHS programs result in earlier identification of PBHL and may improve neurodevelopment. UNHS should be implemented across high-, middle-, and low-income countries.RegistrationPROSPERO (CRD42020175451)

Targeted screening for congenital cytomegalovirus: A micro-costing analysis.

We aimed to determine the cost and potential cost-savings of delivering a targeted congenital cytomegalovirus (cCMV) screening programme through a universal newborn hearing screening (UNHS) programme to detect cCMV-related hearing loss in infants from Victoria, Australia. We completed a micro-costing analysis from a health-care perspective using data from a targeted cCMV screening programme piloted between June 2019 and March 2020. The programme involved collection of saliva samples to test for cCMV in infants who: received a 'refer' result on their second newborn hearing screen; were aged 21 days or less; and born at one of four maternity hospitals in Victoria, Australia. All costs to complete targeted cCMV screening were recorded in Australian 2020 dollars. Potential costs and benefits of adding targeted cCMV screening to the pre-existing UNHS programme were compared to when no screening was available up to 18 years to determine the likely cost or cost savings. The cost of adding targeted cCMV screening to Victoria's UNHS is $202 per infant screened. The total cost per positive case identified is $21 456. The overall cost of adding targeted salivary cCMV screening at the point of a second 'refer' result on the UNHS programme in Victoria's four largest hospitals is estimated to be $28 966 for the first year. Targeted screening for cCMV provides families the opportunity to detect and, if appropriate, treat cCMV in the first month of life in line with current recommendations. It falls within the range between cost neutral and cost saving.

Availability of data for cost-effectiveness comparison of child vision and hearing screening programmes.

For cost-effectiveness comparison of child vision and hearing screening programmes, methods and data should be available. We assessed the current state of data collection and its availability in Europe. The EUSCREEN Questionnaire, conducted in 2017-2018, assessed paediatric vision and hearing screening programmes in 45 countries in Europe. For the current study, its items on data collection, monitoring and evaluation, and six of eleven items essential for cost-effectiveness analysis: prevalence, sensitivity, specificity, coverage, attendance and loss to follow-up, were reappraised with an additional questionnaire. The practice of data collection in vision screening was reported in 36% (N = 42) of countries and in hearing screening in 81% (N = 43); collected data were published in 12% and 35%, respectively. Procedures for quality assurance in vision screening were reported in 19% and in hearing screening in 26%, research of screening effectiveness in 43% and 47%, whereas cost-effectiveness analysis was performed in 12% for both. Data on prevalence of amblyopia were reported in 40% and of hearing loss in 77%, on sensitivity of screening tests in 17% and 14%, on their specificity in 19% and 21%, on coverage of screening in 40% and 84%, on attendance in 21% and 37%, and on loss to follow-up in 12% and 40%, respectively. Data collection is insufficient in hearing screening and even more so in vision screening: data essential for cost-effectiveness comparison could not be reported from most countries. When collection takes place, this is mostly at a local level for quality assurance or accountability, and data are often not accessible. The resulting inability to compare cost-effectiveness among screening programmes perpetuates their diversity and inefficiency.

Summary of the Polish Universal Neonatal Hearing Screening Program 2021year review.

The Polish Universal Neonatal Hearing Screening Program (PUNHSP) has been carried out in Poland for 20 years. Its main goal is to screen newborns for hearing. This examination is performed on the 2-3 days of a child&apos;s life, and in addition, information is collected on the risk factors for the development of hearing loss. In total, 486 centers participate in PPPBSuN at three reference levels. By the end of 2021, 7 million children were registered in the PPPBSuN Central Database. The most common type of hearing loss in children was bilateral sensorineural hearing loss, diagnosed in 2021 in 160 children. The report below presents the most important results and conclusions from the functioning of PPPBSuN in 2021.

The Effectiveness of the School-Age Hearing Screening Program in Turkey and the Effects of the COVID-19 Pandemic

The aim of the study is to evaluate the effectiveness of the hearing screening program in school-age children in Turkey, and to discuss alternative methods for children who cannot be screened due to the COVID-19 pandemic. Within the scope of the school-age hearing screening program, children who fail the screening are referred to reference centers. The effectiveness of the screening program was investigated by recording the ear examinations and definitive audiometric examination results of the children who were referred to a tertiery-level center. Evaluations were made of a total of 87 children, comprising 49 boys (56.3%) and 38 girls (43.7%) with a mean age of 6.97 years, and no risk factors for hearing loss. The physical examination results showed that 53 children were normal, 15 had cerumen impaction, 3 otitis externa, 13 otitis media with effusion and 3 acute otitis media. The audiometric examination results were recorded as 72 normal, 13 conductive hearing loss, and 2 sensorineural hearing loss. Thus, the false positive rate of screening audiometry performed at school was 82.7%. School-age hearing screening is an important test to ensure the cognitive and academic development of children. Pure tone audiometry is indispensable in the evaluation of children who fail the test. For the evaluation of children who could not be tested for 1.5 years due to the COVID-19 pandemic, alternative methods such as tele-audiometry may be utilized.

Have newborn hearing screening programs been affected by the COVID-19 pandemic?

Introduction Due to the vital importance of early diagnosis and intervention of congenital hearing loss, the aim of this study was to compare the rate of newborn hearing screening before and after the COVID-19 pandemic quarantine. Materials and methods In this study, the data related to 6144 newborns during two 18-month time periods before and after the onset of the COVID-19 pandemic quarantine, was analyzed. Results From all visited newborns, 3770 and 2374 referred to the centre before and after the COVID-19 pandemic quarantine, respectively. There were statistically significant differences in the results of screening and the referral rate of neonates before and after the pandemic (p = 0.00). The results showed that both the residents of urban and rural regions visited for newborn hearing screening less frequently after the onset of the pandemic, but no statistically significant difference was shown between the number of boys and girls before and after the pandemic (p = 0.72). Conclusion Our results help gain new insights regarding the impacts of disruptive events such as pandemics on the implementation of health screening programs. Boosting public knowledge by providing families with proper education appears to be helpful in preventing the negative effects of delayed implementation of health screening programs.

Audiological Risk Factors, Referral Rates and Dropouts: 9 Years of Universal Newborn Hearing Screening in North Sardinia.

Background: Objectives of the present work were to analyze the prevalence of hearing loss in our population of screened newborns during the first 9 years of the universal newborn hearing screening (UNHS) program at University Hospital Sassari (Italy) (AOU Sassari), to analyze the risk factors involved, and to analyze our effectiveness in terms of referral rates and dropout rates. Methods: Monocentric retrospective study whose target population included all the newborns born or referred to our hospital between 2011 and 2019. Results: From 2011 to 2019, a total of 11,688 babies were enrolled in our screening program. In total, 3.9‰ of wellborn babies and 3.58% of neonatal intensive care unit (NICU) babies had some degree of hearing loss. The most frequently observed risk factors among non-NICU babies were family history of hearing loss (3.34%) and craniofacial anomalies (0.16%), among NICU babies were low birth weight (54.91%) and prematurity (24.33%). In the multivariate analysis, family history of hearing loss (p < 0.001), NICU (p < 0.001), craniofacial anomalies (p < 0.001), low birth weight (<1500 g) (p = 0.04) and HIV (p = 0.03) were confirmed as risk factors. Conclusions: Our data are largely consistent with the literature and most results were expected, one relevant exception being the possible role of NICU as a confounding factor and the limited number of risk factors confirmed in the multivariate analysis.

School hearing screening: international experience and recommendations

Permanent childhood hearing loss is crucial for speech development and restricts learning abilities. Universal newborn hearing screening programs are well established to detect congenital hearing loss and address the need of hearing-impaired babies. Progressive or acquired permanent hearing loss can manifest later due to genetic causes, intrauterine or postnatal infections, middle ear diseases and excessive exposure to noise when listening the personal audio devices. The hearing loss prevalence in the population of 9 year-olds three times higher compared with newborns. School hearing screening is a part of hearing across the lifespan conception. The article presents international experience and recommendations for the organization of school hearing screening programs. A school-entry hearing test is mandatory, other grades might be screened also. The basic method is pure tone audiometry at frequencies of 500, 1 000, 2 000, 4 000 Hz at 20 dB. Otoscopy and tympanometry can be performed also, while whisper voice speech test is of low sensitivity. The main hearing screening issue is low follow-up of referrals to ascertain audiological assessment. Modern approaches to the prevention of hearing loss in schoolchildren and management of hearing impairements are described. Planning of hearing screening programs requires sufficient human and logistical resources, monitoring of results and quality improvement, all stakeholders engagement.

Pediatricians' knowledge and attitude toward hearing loss and newborn hearing screening programs

IntroductionEarly detection of hearing loss is important to the management of infants and young children with hearing loss. Pediatricians are often the first to encounter a child suspected to have hearing loss. The objective of this study is to evaluate the knowledge and attitude of newborn hearing screening and management of hearing in among pediatricians. MethodsA cross-sectional survey-based study utilizing a validated questionnaire that was distributed to pediatricians in single tertiary academic health care institution that aims to evaluate the knowledge and attitudes related to children with hearing loss and newborn hearing screening. ResultsA total of 67 pediatricians agreed to participate and were involved in our study. Mean age was 35 years and 44.1% were males. The majority (79.4%) thought it was very important to have a newborn hearing screening program. However, two-thirds (64.7%) were unsure that there is a universal hearing screening program in the country. Never the less, the majority of the respondents (75%) were at least somewhat confident in explaining the hearing screening program process in our institution. There was a gap in the knowledge of our pediatricians with regard to the process of dealing with a newborn who failed screening program and the candidacy for cochlear implants. Also, some participants were unsure whether to refer a child with hearing impairment to an otolaryngologist or not. Most of the participants thought that physicians need more information related to permanent hearing loss. ConclusionThere are gaps in Pediatricians knowledge and awareness towards hearing loss assessment and management in newborns. This likely requires further academic collaboration between specialties to improve the care of newborns. Future research should focus on the auditory and speech outcome and rehabilitation awareness.

Protocol and programme factors associated with referral and loss to follow-up from newborn hearing screening: a systematic review

BackgroundAn effective newborn hearing screening programme has low referral rate and low loss to follow-up (LTFU) rate after referral from initial screening. This systematic review identified studies evaluating the effect of protocol and programme factors on these two outcomes, including the screening method used and the infant group.MethodsFive databases were searched (latest: April 2021). Included studies reported original data from newborn hearing screening and described the target outcomes against a protocol or programme level factor. Studies were excluded if results were only available for one risk condition, for each ear, or for < 100 infants, or if methodological bias was observed. Included studies were evaluated for quality across three domains: sample, screening and outcome, using modified criteria from the Ottawa-Newcastle and QUADAS-2 scales. Findings from the included studies were synthesised in tables, figures and text.ResultsFifty-eight studies reported on referral rate, 8 on LTFU rate, and 35 on both. Only 15 studies defined LTFU. Substantial diversity in referral and LTFU rate was observed across studies. Twelve of fourteen studies that evaluated screening method showed lower referral rates with aABR compared to TEOAE for well babies (WB). Rescreening before hospital discharge and screening after 3 days of age reduced referral rates. Studies investigating LTFU reported lower rates for programmes that had audiologist involvement, did not require fees for step 2, were embedded in a larger regional or national programme, and scheduled follow-up in a location accessible to the families. In programmes with low overall LTFU, higher LTFU was observed for infants from the NICU compared to WB.ConclusionAlthough poor reporting and exclusion of non-English articles may limit the generalisability from this review, key influential factors for referral and LTFU rates were identified. Including aABR in WB screening can effectively reduce referral rates, but it is not the only solution. The reported referral and LTFU rates vary largely across studies, implying the contribution of several parameters identified in this review and the context in which the programme is performed. Extra attention should be paid to infants with higher risk for hearing impairment to ensure their return to follow-up.

Hearing loss among inmates of a juvenile correctional facility in Nigeria.

Good hearing is essential to learning and rehabilitation of adolescent and young adults in juvenile correctional facilities. Hearing screening programme is not commonly in place for this incarcerated group. To evaluate hearing threshold among inmates of a juvenile correctional facility in Nigeria and compare pattern of hearing loss with a control group. A total of 135 inmates and equal number of age and sex matched control responded to interviewer-administered questionnaire followed by otoscopy and audiometry. Mean age of inmates was 19 years ±2.0, while that of control was 18yrs ± 2.5. (p-value 0.077). Four (3%) inmates had bleeding from the ear; otoscopy revealed traumatic tympanic membrane perforation in 2(1.5%) of them. Prevalence of hearing loss was 19.2% and for disabling hearing loss it was 1.4%. Conductive hearing loss was the most common 33(24.4%). Inmates had consistently worse mean hearing thresholds than controls across all frequencies tested in both ears (p-value <0.001). Hearing loss is prevalent among inmates of juvenile correctional facility. Rehabilitation programme should be balanced with detail attention to health needs of inmates; including pre-admission and periodic hearing screening.

The Impact of COVID-19 on Universal Newborn Hearing Screening.

To report the direct and indirect impact of coronavirus disease 2019 pandemic on the Universal Newborn Hearing Screening program of our institution (Azienda Ospedaliero Universitaria di Sassari). Monocentric retrospective study whose target population included all the newborns born in or referred to our hospital in 2019 and 2020. There is no statistically significant difference in time to retest or loss to follow-up rate between the 2 years considered (2019 to 2020). Referral rate is not higher for newborns born to severe acute respiratory syndrome coronavirus 2 polymerase chain reaction positive mothers. In relation to the analyzed variables, coronavirus disease 2019 seems to have a limited impact on our screening program. Severe acute respiratory syndrome coronavirus 2 did not behave as an audiological risk factor in our series.

Do all infants with congenital hearing loss meet the 1-3-6 criteria? A study of a 10-year cohort from a universal newborn hearing screening programme in Singapore

Objective To evaluate 1) the outcomes of a local universal newborn hearing screening (UNHS) programme and its audiological follow-ups at 3- and 6-month points, 2) the education outcomes of children with congenital hearing loss (CHL). Design Retrospective study that analysed data containing hearing screening, diagnosis, intervention and schooling information from electronic databases. Study sample Children aged 5 to 15 years old who were born between 2004–2014 and underwent UNHS in a local hospital. Results Over a 10-year cohort, 99.4% of 29,972 newborns underwent UNHS; approximately 90% of them were screened by 1 month of age. However, only 10% of the cohort strictly fulfilled the 1-3-6 criteria recommended by the Joint Committee on Infant Hearing. Lost to follow-up (LTF) rate was highest at post-diagnosis (35%). 80% of infants who were intervened between 6 and 48 months of age went to mainstream schools. The remaining 20% had additional disabilities or family factors. Conclusions A high UNHS coverage rate may not translate to meeting the 1-3-6 criteria. Despite ease of access to our healthcare system, LTF at post-diagnosis remained high. In the absence of additional disabilities or family factors, infants intervened during the sensitive window could still potentially make it into mainstream schools.

A Prospective Study of Etiology and Auditory Profiles in Infants with Congenital Unilateral Sensorineural Hearing Loss.

Congenital unilateral sensorineural hearing loss (uSNHL) is associated with speech-language delays and academic difficulties. Yet, controversy exists in the choice of diagnosis and intervention methods. A cross-sectional prospective design was used to study hearing loss cause in twenty infants with congenital uSNHL consecutively recruited from a universal neonatal hearing-screening program. All normal-hearing ears showed ≤20 dB nHL auditory brainstem response (ABR) thresholds (ABRthrs). The impaired ear median ABRthr was 55 dB nHL, where 40% had no recordable ABRthr. None of the subjects tested positive for congenital cytomegalovirus (CMV) infection. Fourteen subjects agreed to participate in magnetic resonance imaging (MRI). Malformations were common for all degrees of uSNHL and found in 64% of all scans. Half of the MRIs demonstrated cochlear nerve aplasia or severe hypoplasia and 29% showed inner ear malformations. Impaired ear and normal-hearing ear ABR input/output functions on a group level for subjects with ABRthrs < 90 dB nHL were parallel shifted. A significant difference in interaural acoustic reflex thresholds (ARTs) existed. In congenital uSNHL, MRI is powerful in finding a possible hearing loss cause, while congenital CMV infection may be relatively uncommon. ABRs and ARTs indicated an absence of loudness recruitment, with implications for further research on hearing devices.

Programas de triagem auditiva neonatal: indicadores de qualidade e acesso aos serviços de saúde

Abstract Objectives: to verify the quality indicators of neonatal hearing screening programs, identify the most prevalent risk factors for hearing loss and analyze access to the Hearing Health Care Network. Methods: cross-sectional study using secondary data. The population are children born in public maternity hospitals from 2015 to 2019. Data collection was carried out in the database of programs and hearing health service. The absolute and relative frequencies of all variables collected and the median, the interquartile range and the Mann-Whitney test were calculated to analyze the access. Results: universality increased during the study period, but was not reached (71.9%; CI95%=70.4-73.3) and the referral rate for auditory diagnosis was within the recommended range (0.9%; CI95%=0.8-0.9). The most prevalent risk factors were congenital infections and heredity. There was an evasion of children to the hearing health service of 85.1% and the type of referral interfered with the age of the child at access. Eight children with hearing loss were diagnosed, in which seven had access to therapeutic interventions. Conclusions: hearing screening was not universal. Access to the Hearing Health Care Network presents high evasion and interventions were offered to children with hearing loss.

The impact of the COVID 19 pandemic on the functioning of the Universal Newborn Hearing Screening Program in Poland

The Newborn Hearing Screening Program has existed in Poland for almost 20 years. However, for the first time in the history of his activity, he had to deal with large logistic and staffing problems. The analysis compared the years 2020 and 2021 in terms of the functioning of centers that conduct audiological diagnostics of the Program during the Covid-19 pandemic. In order to obtain relevant information, a telephone survey was conducted at the beginning of 2022 with questions about the performance of standard activities related to the Program. Results In 2020, 60 centers conducting audiological diagnostics (66.67%) were suspended, and 30 were working under the sanitary and epidemiological regime (33.33%). In 2021, only 5 (5.26%) diagnostic centers with their headquarters in facilities transformed into so-called homonymous hospitals, dealing only with the treatment of patients infected with SARS-CoV-2 virus, were suspended. Discussion The development of the pandemic and the related limitations around the world had a significant impact on the quality and scope of medical services provided. Many hospitals were quickly transformed into closed centers treating only patients with SARS-CoV-2. Audiological consultations take place in closed, soundproof rooms. Face-to-face contact was required for hearing assessment, fitting hearing aids, troubleshooting, and rehabilitation. The COVID-19 pandemic has forced audiology to modify existing practices. The use of telemedicine was increasingly preferred. In Poland, as all over the world, the scope of remote consultations has expanded, but due to technological and hardware limitations, audiological procedures remained in the sphere of direct contact with the patient. Conclusions In the first year after the announcement of the pandemic, significant difficulties were observed in the functioning of centers dealing with the diagnosis of children with suspected hearing loss. The appearance of the SARS-CoV-2 virus forced us to develop innovative methods of early diagnosis and treatment of children with hearing impairment, which resulted in the stabilization of the work of individuals in the following year.

Incorporating hearing screening to an otolaryngology surgical mission in the rural Dominican Republic

IntroductionHearing loss disproportionately affects low- and middle-income countries. Children with undiagnosed hearing loss may have difficulty with learning, language development, and behavior. The aim of this study was to understand the extent of hearing loss and common otologic disorders among school-age children in the rural western region of the Dominican Republic and to chronical the early stages of a limited-resource, locally-sustained hearing screening program in tandem with a bi-annual surgical mission. MethodsHearing screenings were performed for 528 school-age children (1056 ears, age 5–17 years old) over 5 days in a village hospital in Peralta, DR. Testing initially included otoscopy and screening audiometry. Children who referred or could not be conditioned underwent distortion product otoacoustic emissions (OAEs), and tympanometry. Children who referred following both screening audiometry and OAEs were considered to have hearing loss. Those with normal tympanograms were considered potential hearing aid candidates. ResultsAbnormal ear examination/otoscopic results were present in 43 children (8.1%) and included: microtia/atresia, impacted cerumen, ear canal foreign body, serous otitis media, otitis externa, and tympanosclerosis. 55 of 528 school-age children referred following screening audiometry and 7 were unable to condition. Of these 62 children, 56 tolerated OAEs and 20 referred following OAEs (3.8%). Fourteen children had type B or C tympanogram and 6 school-age children who were determined to have chronic otitis media with effusion (COME) underwent myringotomy and pressure equalization tube placement. Ten of 528 children (1.9%) had normal tympanometry and otoscopy, and referred following screening audiometry and OAEs suggesting the patients may be potential hearing aid candidates. ConclusionsThe prevalence of hearing loss in this cohort of children in the rural, western Dominican Republic was high at roughly 4% with roughly 2% of children being potential hearing aid candidates. Nearly 10% of children screened had an abnormal otologic examination; sometimes easily remedied by otolaryngologic intervention. With the support of local leadership, it is feasible to incorporate hearing services into otolaryngology outreach and build locally sustainable programs.

Three Years of Vestibular Infant Screening in Infants With Sensorineural Hearing Loss.

Although vestibular deficits are more prevalent in hearing-impaired children and can affect their development on many levels, a pediatric vestibular assessment is still uncommon in clinical practice. Since early detection may allow for timely intervention, this pioneer project has implemented a basic vestibular screening test for each six-month-old hearing-impaired infant in Flanders, Belgium. This study aims to report the vestibular screening results over a period of three years and to define the most important risk factors for abnormal vestibular screening results. Cervical Vestibular Evoked Myogenic Potentials with bone-conduction were used as a vestibular screening tool in all reference centers affiliated to the Universal Newborn Hearing Screening Program in Flanders. From June 2018 until June 2021, 254 infants (mean age: 7.4 months, standard deviation: 2.4 months) with sensorineural hearing loss were included. Overall, abnormal vestibular screening results were found in 13.8% (35 of 254) of the infants. The most important group at risk for abnormal vestibular screening results were infants with unilateral or bilateral severe to profound sensorineural hearing loss (20.8%, 32 of 154) (P < .001, odds ratio = 9.16). Moreover, abnormal vestibular screening results were more prevalent in infants with hearing loss caused by meningitis (66.7%, 2 of 3), syndromes (28.6%, 8 of 28), congenital cytomegalovirus infection (20.0%, 8 of 40), and cochleovestibular anomalies (19.2%, 5 of 26). The vestibular screening results in infants with sensorineural hearing loss indicate the highest risk for vestibular deficits in severe to profound hearing loss, and certain underlying etiologies of hearing loss, such as meningitis, syndromes, congenital cytomegalovirus, and cochleovestibular anomalies.

Delayed Cochlear Implantation in Children: A Parental Survey

Background: Untreated childhood hearing loss can adversely affect speech and language development as well as academic, social, emotional, and behavioral development. Early cochlear implantation before the age of 4 years, within the critical period for central auditory development, was found to be crucial in reducing the negative impact of auditory deprivation and appears to provide better outcomes than late implantation.&#x0D; aim: The aim of this study was to determine the reasons behind late cochlear implantation in children with congenital severe to profound sensorineural hearing loss.&#x0D; Methods: A retrospective study was conducted on all cases who received cochlear implants at Specialty Surgical Center, Benghazi, Libya between October 2017 and June 2021. Patients' medical records were reviewed and demographic and clinical data were collected. Children with other disabilities, and post-lingual and post-meningitis implantees were excluded from the study. Information about the reasons for the delay in receiving cochlear implants was obtained over the phone from parents whose children underwent cochlear implant surgery beyond the age of 4 years.&#x0D; Results: A total of 74 children were included, 38 boys and 36 girls. The mean age at implantation was 47 months. Forty-one percent (41%) of children were implanted after 4 years of age. Two-thirds of these children live outside Benghazi. Most of the children had at least one risk factor for hearing loss. The majority of parents reported more than one reason for the delayed implantation.&#x0D; Conclusion: It is found that parent decision-making for cochlear implantation is difficult and affected by many factors, including their personal beliefs (denial, social stigma and fear of surgery), lack of awareness about the existence of cochlear implant technology, and financial constraints. It is recommended that a national newborn hearing screening program is established for early detection and intervention and cost-effectiveness.
