ABSTRACT
INTRODUCTION: Pediatric hearing loss can significantly impact speech, language, social, and educational development. Providing access to speech and environmental sounds using amplification devices, such as hearing aids, can help improve developmental outcomes. However, timely rehabilitation and intervention may be delayed due to limited access to resources, further prolonging the adverse effects of childhood hearing loss. The aim of this study was to investigate socioeconomic barriers in time to dispensing hearing aids in a diverse pediatric patient population. METHODS: Data from an existing internal database from a tertiary pediatric hospital were analyzed from January 2020 through August 2022 for barriers associated with hearing aid (HA) dispensing delays. Demographic and clinical characteristics were obtained. Multivariate regression and survival analysis statistics were used to identify factors associated with delayed time to dispensing hearing aids. RESULTS: Of the 121 patients who had been appropriately diagnosed and fit, 108 (89.3%) had received hearings aids and 13 (10.7%) had not at the time of the study. Of those who had received HA, time to dispensing was not significantly impacted by sex, race, ethnicity, language, or income level. Insurance was found to be an influencing factor in time to receiving the HA. CONCLUSION: Factors such as insurance and hearing loss laterality contribute to delays in receiving hearing aids. Identifying these specific barriers and disparities in hearing rehabilitation services will prove vital in facilitating an expedited and equitable pathway to receiving hearing aids.

ABSTRACT
OBJECTIVE: Operating room (OR) sounds may surpass noise exposure thresholds and induce hearing loss. Noise intensity emitted by various surgical instruments during common pediatric otolaryngologic procedures were compared at the ear-level of the surgeon and patient to evaluate the need for quality improvement measures. STUDY DESIGN: Cross-sectional study. SETTING: Single tertiary care center. METHODS: Noise levels were measured using the RISEPRO Sound Level Meter and SoundMeter X 10.0.4 at the ear level of surgeon and patient every 5 minutes. Operative procedure and instrument type were recorded. Measured noise levels were compared against ambient noise levels and the Apple Watch Noise application. RESULTS: Two hundred forty-two total occasions of noise were recorded across 62 surgical cases. Cochlear implantation surgery produces the loudest case at the ear-level of the patient (91.8 Lq Peak dB; P < .001). The otologic drill was the loudest instrument for the patient (92.1 Lq Peak dB; P < .001), while the powered microdebrider was the loudest instrument for the surgeon (90.7 Lq Peak dB; P = .036). Noise measurements between surgeon and patient were similar (P < .05). Overall agreement between the Noise application and Sound Level Meter was excellent (intraclass correlation coefficient of 0.8, with a 95% confidence interval ranging from 0.32 to 0.92). CONCLUSION: Otolaryngology OR noises can surpass normal safe thresholds. Failure to be aware of this may unwittingly expose providers to noise-related hearing loss. Mitigation strategies should be employed. Quality improvement measures, including attention to surgical instrument volume settings and periodic decibel measurements with sound applications, can promote long-term hearing conservation. DISCUSSION: Otolaryngology OR noises can surpass normal safe thresholds. Failure to be aware of this may unwittingly expose providers to noise-related hearing loss. The duration, frequency of exposure, and volume levels of noise should be studied further. IMPLICATIONS FOR PRACTICE: Mitigation strategies should be employed. Quality improvement measures, including attention to surgical instrument volume settings and periodic decibel measurements with sound applications, can promote long-term hearing conservation.
ABSTRACT
OBJECTIVE: To identify associations between cochleovestibular anatomy findings and hearing outcomes found in children with imaging evidence of an absent or hypoplastic cochlear nerve treated with cochlear implantation (CI). STUDY DESIGN: retrospective review. SETTING: Cochlear implant program at tertiary care center. METHODS: A retrospective review was performed to identify children with imaging evidence of cochlear nerve absence or deficiency who underwent CI evaluation. High-resolution 3-dimensional T2-weighted magnetic resonance imaging in the oblique sagittal and axial planes were reviewed by a neuroradiologist to identify cochleovestibular anatomy. Hearing was assessed pre and postoperatively with Speech Perception Category scores. RESULTS: Seven CI recipients were identified (n = 10 ears) who had bilateral severe to profound sensorineural hearing loss with lack of auditory development with binaural hearing aid trial and imaging evidence of cochlear nerve aplasia/hypoplasia. All ears had 2 nerves in the cerebellopontine angle (100%, n = 10), half of the ears had evidence of 2 or less nerves in the internal auditory canal (IAC). All children showed large improvement in speech perception after CI. CONCLUSION: Our experience with CIs for children with absent or hypoplastic cochlear nerves demonstrates that CI can be a viable option in select patients who satisfy preoperative audiological criteria. Radiological identification of a hypoplastic or aplastic cochlear nerve does not preclude auditory innervation of the cochlea. CI recipients in this subgroup must be counseled on difficulty in predicting postimplantation language and speech outcomes, and cautioned about facial nerve stimulation.
ABSTRACT
OBJECTIVES: The purpose of this study is to evaluate for discrepancies in diagnostic auditory brainstem responses (ABR) between Children's National Hospital (CNH), a pediatric medical center, and outside facilities (OSF) that referred patients to CNH for confirmatory evaluation. Such discrepancies impact early hearing detection and intervention (EHDI) timelines. METHODS: A retrospective chart review was conducted from an internal database of patients who underwent diagnostic ABR from 2017 to 2021. Only patients with ABR results from both CNH and OSF were analyzed. Demographic data, external and internal test results, and intervention data were obtained. Hearing loss (HL) severity was graded on a scale of 0 to 8, where 0 indicated normal hearing and 8 indicated profound. Each ear was analyzed separately. RESULTS: Forty-nine patients met the inclusion criteria, and each ear was evaluated separately. Median HL severity was 1.0 [0.0, 4.3] at CNH compared to 3.0 [1.8, 6] at OSF (p = 0.004). Forty-seven ears (48.0%) showed lower severity at CNH. Twenty-seven patients (55%) received hearing amplification devices. The median age at time of hearing intervention was 220 days. CONCLUSION: Our results showed statistical significance in the median severity of HL between CNH and OSF. A substantial proportion (70%) of children in our dataset who received amplification via cochlear implant or hearing aids were shown to have discrepancies in ABR findings from CNH and OSF. These findings have implications with regards to the appropriate usage of health care resources and maintaining EDHI timelines.

BACKGROUND: The United States Virgin Islands (USVI) Department of Health (DOH) conducted a second Zika health brigade (ZHB) in 2021 to provide recommended Zika-related pediatric health screenings, including vision, hearing, neurologic, and developmental screenings, for children in the USVI. This was replicated after the success of the first ZHB in 2018, which provided recommended Zika-related pediatric health screenings to 88 infants and children exposed to Zika virus (ZIKV) during pregnancy. METHODS: Ten specialty pediatric care providers were recruited and traveled to the USVI to conduct the screenings. USVI DOH scheduled appointments for children included in CDC's U.S. Zika Pregnancy and Infant Registry (USZPIR). During the ZHB, participants were examined by pediatric ophthalmologists, pediatric audiologists, and pediatric neurologists. We report the percentage of participants who were referred for additional follow-up care or given follow-up recommendations in the 2021 ZHB and compare these referrals and recommendations to those given in the 2018 ZHB. RESULTS: Thirty-three children born to mothers with laboratory evidence of ZIKV infection during pregnancy completed screenings at the 2021 ZHB, of which 15 (45%) children were referred for additional follow-up care. Ophthalmological screenings resulted in the highest number of new referrals for a specialty provider among ZHB participants, with 6 (18%) children receiving referrals for that specialty. Speech therapy was the most common therapy referral, with 10 (30%) children referred, of which 9 (90%) were among those who attended the 2018 ZHB. CONCLUSIONS: Thirty-three children in a jurisdiction with reduced access to healthcare specialists received recommended Zika-related pediatric health screenings at the ZHB. New and continuing medical and developmental concerns were identified and appropriate referrals for follow-up care and services were provided. The ZHB model was successful in creating connections to health services not previously received by the participants.

IMPORTANCE: Research has suggested that early cochlear implantation is associated with improved language outcomes. Select studies demonstrate that this translates into a higher quality of life following implantation. Previous work from our group has shown that underinsurance represents a risk factor for worsened auditory and language outcomes for implantees. However, to our knowledge, the effect of insurance status on quality of life outcomes following cochlear implantation has not been evaluated. OBJECTIVE: To assess quality of life outcomes for children receiving cochlear implants, accounting for age at implantation, insurance status, gender, surgeon, number of implants and duration of follow-up since implantation. DESIGN: A retrospective study using the Glasgow Children's Benefit Inventory (GCBI), a validated questionnaire measuring quality of life across four domains: learning, emotion, vitality and physical heath. Multivariate linear regression was used to examine the effects of age at implantation, insurance status, number of implants, sex, surgeon, and duration of follow-up on GCBI scores. Age at implantation was assessed as both a continuous and dichotomous variable, comparing children implanted by 12 months of age with those implanted after 12 months. SETTING: Children's National Health System in Washington, DC, a tertiary academic referral center. PARTICIPANTS: The GCBI was administered telephonically to parents/guardians of prelingually deaf children aged 2-16 years who received cochlear implants at the center between January 1, 2008 and December 31, 2018. RESULTS: Of 169 prelingually deafened implantee children who met inclusion criteria, parents/guardians of 64 (37.9%) responded to the questionnaire. After excluding children with late implantation (≥7 years age at CI) and missing GCBI responses, the final analytic sample consisted of 57 children. The mean age (SD) of the children at the time of the study was 3.3 (1.9) years, 63.2% were publicly insured, and 73.7% were implanted after 12 months of age. Average duration of follow-up was 3.9 (2.8) years. On a scale of -100 to +100, GCBI scores ranged from 41.7 to 95.8 (mean (SD), 64.0 (10.3)). Public health insurance (ß, -5.8 [95% CI, -10.6 to -0.01]), and older age at the time of implantation (ß, -0.1 [95% CI, -0.3 to 0.0]), particularly implantation following 12 months of age (p < 0.05), were significantly associated with lower GCBI scores after implantation. CONCLUSION: Publicly insured recipients of cochlear implants and children implanted at an older age, particularly after 12 months of age, experienced significantly lower quality of life measures.

The objective of the study was to describe the complexity of diagnosis and evaluation of Zika-exposed pregnant women/fetuses and infants in a U.S. Congenital Zika Program. Pregnant women/fetuses and/or infants referred for clinical evaluation to the Congenital Zika Program at Children's National (Washington, DC) from January 2016 to June 2018 were included. We recorded the timing of maternal Zika-virus (ZIKV) exposure and ZIKV laboratory testing results. Based on laboratory testing, cases were either confirmed, possible, or unlikely ZIKV infection. Prenatal and postnatal imaging by ultrasound and/or magnetic resonance imaging (MRI) were categorized as normal, nonspecific, or as findings of congenital Zika syndrome (CZS). Of 81 women-fetus/infant pairs evaluated, 72 (89%) had confirmed ZIKV exposure; 18% of women were symptomatic; only a minority presented for evaluation within the time frame for laboratory detection. Zika virus could only be confirmed in 29 (40%) cases, was possible in 26 (36%) cases, and was excluded in 17 (24%) cases. Five cases (7%) had prenatal ultrasound and MRI findings of CZS, but in only three was ZIKV confirmed by laboratory testing. Because of timing of exposure to presentation, ZIKV infection could not be excluded in many cases. Neuroimaging found CZS in 7% of cases, and in many patients, there were nonspecific imaging findings that warrant long-term follow-up. Overall, adherence to postnatal recommended follow-up evaluations was modest, representing a barrier to care. These challenges may be instructive to future pediatric multidisciplinary clinics for congenital infectious/noninfectious threats to pregnant women and their infants.
