Economic Analysis of Cochlear Implants in Adults With Bilateral Severe-to-Profound Hearing Loss. A Systematic Review of the Literature.

OBJECTIVE: To determine the cost-effectiveness or cost-utility of cochlear implants (CI) in adults with severe to profound bilateral hearing loss. DATABASES REVIEWED: PubMed (Medline), The Cochrane Library, Embase via Elsevier, EBSCOhost CINAHL, and Scopus. METHODS: The study included adult participants with severe to profound bilateral neurosensory hearing loss. The analysis encompassed quality of life improvements, costs, cost-effectiveness, cost-utility, cost-benefit, quality-adjusted life year (QALY), incremental cost-effectiveness ratio (ICER), and incremental cost-utility ratio (ICUR). Systematic reviews, meta-analyses, case series, and prospective or retrospective cohort studies published in English between 2010 and 2023 were retrieved. Exclusion criteria included incomplete studies, abstracts, clinical cases, editorials, letters, studies involving pediatric populations, single-side deafness, methodology research, noneconomic aspects of CI, mixed child and adult data, and studies published before 2010. The risk of bias was assessed following the criteria outlined in Appendix I of the economic evaluation's quality assessment as per the NICE Guideline Development Method. RESULTS: Ten articles met the criteria and were included in the qualitative synthesis. One study conducted a prospective cost-utility analyses, one carried out a cost-benefit analyses, one was a randomized controlled clinical trial focusing on cost-utility, and another was a clinical trial addressing cost-effectiveness. Six studies employed Markov models, and one study utilized uniquely the Monte Carlo method. None quantified the economic impact of improved hearing on cognitive function. CONCLUSIONS: The heterogeneity of sources impacted data quality. Unilateral and sequential bilateral CI appeared to be cost-effective when compared with bilateral hearing aids or nontechnological support. When properly indicated, simultaneous bilateral CIs are cost-effective compared to no interventions and to unilateral cochlear implantation through differential discounting or variations from the base cases, especially with a life expectancy of 5-10 years or longer.

Self-Assessment of Cochlear Health by New Cochlear Implant Recipients: Daily Impedance, Electrically Evoked Compound Action Potential and Electrocochleography Measurements Over the First Three Postoperative Months.

HYPOTHESES: In newly implanted cochlear implant (CI) users, electrically evoked compound action (eCAPs) and electrocochleography (ECochGs) will remain stable over time. Electrode impedances will increase immediately postimplantation due to the initial inflammatory response, before decreasing after CI switch-on and stabilizing thereafter. BACKGROUND: The study of cochlear health (CH) has several applications, including explaining variation in CI outcomes, informing CI programming strategies, and evaluating the safety and efficacy of novel biological treatments for hearing loss. Very early postoperative CH patterns have not previously been intensively explored through longitudinal daily testing. Thanks to technological advances, electrode impedances, eCAPs, and ECochGs can be independently performed by CI users at home to monitor CH over time. METHODS: A group of newly implanted CI users performed daily impedances, eCAPs, and ECochGs for 3 months at home, starting from the first day postsurgery (N = 7) using the Active Insertion Monitoring system by Advanced Bionics. RESULTS: Measurement validity of 93.5, 93.0, and 81.6% for impedances, eCAPs, and ECochGs, respectively, revealed high participant compliance. Impedances increased postsurgery before dropping and stabilizing after switch-on. eCAPs showed good stability, though statistical analyses revealed a very small but significant increase in thresholds over time. Most ECochG thresholds did not reach the liberal signal-to-noise criterion of 2:1, with low threshold stability over time. CONCLUSION: Newly implanted CI recipients can confidently and successfully perform CH recordings at home, highlighting the valuable role of patients in longitudinal data collection. Electrode impedances and eCAPs are promising objective measurements for evaluating CH in newly implanted CI users.

Comparison of 96-kV and 120-kV cone-beam CT for the assessment of cochlear implants.

BACKGROUND: To compare the diagnostic value of 120-kV with conventional 96-kV Cone-Beam CT (CBCT) of the temporal bone after cochlear implant (CI) surgery. METHODS: This retrospective study included CBCT scans after CI surgery between 06/17 and 01/18. CBCT allowed examinations with 96-kV or 120-kV; other parameters were the same. Two radiologists independently evaluated following criteria on 5-point Likert scales: osseous spiral lamina, inner and outer cochlear wall, semi-circular canals, mastoid trabecular structure, overall image quality, metal and motion artefacts, depiction of intracochlear electrode position and visualisation of single electrode contacts. Effective radiation dose was assessed. RESULTS: Seventy-five patients (females, n = 39 [52.0%], mean age, 55.8 ± 16.5 years) were scanned with 96-kV (n = 32, 42.7%) and 120-kV (n = 43, 57.3%) protocols including CI models from three vendors (vendor A n = 7; vendor B n = 43; vendor C n = 25). Overall image quality, depiction of anatomical structures, and electrode position were rated significantly better in 120-kV images compared to 96-kV (all p < = 0.018). Anatomical structures and electrode position were rated significantly better in 120-kV CBCT for CI models from vendor A and C, while 120-kV did not provide improved image quality in CI models from vendor B. Radiation doses were significantly higher for 120-kV scans compared to 96-kV (0.15 vs. 0.08 mSv, p < 0.001). CONCLUSIONS: 120-kV and 96-kV CBCT provide good diagnostic images for the postoperative CI evaluation. While 120-kV showed improved depiction of temporal bone and CI electrode position compared to 96-kV in most CI models, the 120-kV protocol should be chosen wisely due to a substantially higher radiation exposure.

Computed tomography multi-planar and 3D image assessment protocol for detailed analysis of inner ear malformations in patients undergoing cochlear implantation counseling.

<b><br>Introduction:</b> Congenital inner ear malformations resulting from embryogenesis may be visualized in radiological scans. Many attempts have been made to describe and classify the defects of the inner ear based on anatomical and radiological findings.</br> <b><br>Aim:</b> The aim was to propose and discuss computed tomography multi-planar and 3D image assessment protocols for detailed analysis of inner ear malformations in patients undergoing cochlear implantation counseling.</br> <b><br>Material and methods:</b> A retrospective analysis of 22 malformed inner ears. CT scans were analyzed using the Multi-Planar Reconstruction (MPR) option and 3D reconstruction.</br> <b><br>Results:</b> The protocol of image interpretation was developed to allow reproducibility for evaluating each set of images. The following malformations were identified: common cavity, cochlear hypoplasia type II, III, and IV, incomplete partition type II and III, and various combinations of vestibule labyrinth malformations. All anomalies have been presented and highlighted in figures with appropriate descriptions for easier identification. Figures of normal inner ears were also included for comparison. 3D reconstructions for each malformation were presented, adding clinical value to the detailed analysis.</br> <b><br>Conclusions:</b> Properly analyzing CT scans in cochlear implantation counseling is a necessary and beneficial tool for appropriate candidate selection and preparation for surgery. As proposed in this study, the unified scans evaluation scheme simplifies the identification of malformations and reduces the risk of omitting particular anomalies. Multi-planar assessment of scans provides most of the necessary details. The 3D reconstruction technique is valuable in addition to diagnostics influencing the decision-making process. It can minimize the risk of misdiagnosis. Disclosure of the inner ear defect and its precise imaging provides detailed anatomical knowledge of each ear, enabling the selection of the appropriate cochlear implant electrode and the optimal surgical technique.</br>.

[Assessment of auditory perception of children with single-sided deafness after cochlear implantation].

Unilateral deafness will lead to the decline of children's speech recognition rate, language development retardation and spatial positioning ability, which will have many adverse effects on children's life and study. Cochlear implantation can help children rebuild binaural hearing, and systematic audiological evaluation after operation is particularly important for clinicians to evaluate the hearing recovery of children. In this study, a variety of commonly used audiological evaluation, testing processes and methods after cochlear implantation in children with unilateral deafness are described in detail, and the related research status and results are summarized.

Intraoperative assessment of cochlear nerve functionality in various vestibular schwannoma scenarios: Lessons learned.

The use of cochlear implants (CIs) is on the rise for patients with vestibular schwannoma (VS). Besides CI following tumor resection, new scenarios such as implantation in observed and/or irradiated tumors are becoming increasingly common. A significant emerging trend is the need of intraoperative evaluation of the functionality of the cochlear nerve in order to decide if a CI would be placed. The purpose of this paper is to explore the experience of a tertiary center with the application of the Auditory Nerve Test System (ANTS) in various scenarios regarding VS patients. The results are compared to that of the studies that have previously used the ANTS in this condition. Patients with unilateral or bilateral VS (NF2) who were evaluated with the ANTS prior to considering CI in a tertiary center between 2021 and 2023 were analyzed. The presence of a robust wave V was chosen to define a positive electrical auditory brainstem response (EABR). Two patients underwent promontory stimulation (PromStim) EABR previous to ANTS evaluation. Seven patients, 2 NF-2 and 5 with sporadic VS were included. The initial scenario was simultaneous translabyrinthine (TL) tumor resection and CI in 3 cases while a CI placement without tumor resection was planned in 4 cases. The ANTS was positive in 4 cases, negative in 2 cases, and uncertain in one case. Two patients underwent simultaneous TL and CI, 1 patient simultaneous TL and auditory brainstem implant, 3 patients posterior tympanotomy with CI, and 1 patient had no implant placement. In the 5 patients undergoing CI, sound detection was present. There was a good correlation between the PromStim and ANTS EABR. The literature research yielded 35 patients with complete information about EABR response. There was one false negative and one false positive case; that is, the 28 implanted cases with a present wave V following tumor resection had some degree of auditory perception in all but one case. The ANTS is a useful intraoperative tool to asses CI candidacy in VS patients undergoing observation, irradiation or surgery. A positive strongly predicts at least sound detection with the CI.

Holistic assessment of cochlear implant outcomes using the international classification of functioning disability and health model: data analysis of a longitudinal prospective multicenter study.

PURPOSE: To study outcome after cochlear implantation using the Cochlear Implant (CI) outcome assessment protocol based on the International Classification of Functioning, Disability and Health (ICF) model (CI-ICF). METHODS: Raw data of a prospective, longitudinal, multicenter study was analyzed. Seventy-two CI candidates were assessed preoperatively and six months postoperatively using the CI-ICF protocol. Following tools were used: (1) Work Rehabilitation Questionnaire (WORQ), (2) Abbreviated Profile of Hearing Aid Benefit (APHAB), (3) Audio Processor Satisfaction Questionnaire (APSQ), (4) Speech, Spatial, and Qualities of Hearing Scale (SSQ12), (5) Hearing Implant Sound Quality Index (HISQUI19), (6) Nijmegen CI Questionnaire (NCIQ) (7) pure tone audiometry, (8) speech audiometry, (9) sound localization. RESULTS: There was a significant improvement of speech discrimination in quiet (p = 0.015; p < 0.001) and in noise (p = 0.041; p < 0.001), sound detection (p < 0.001), tinnitus (p = 0.026), listening (p < 0.001), communicating with-receiving-spoken messages (p < 0.001), conversation (p < 0.001), family relationships (p < 0.001), community life (p = 0.019), NCIQ total score and all subdomain scores (p < 0.001). Subjective sound localization significantly improved (p < 0.001), while psychometric sound localization did not. There was no significant subjective deterioration of vestibular functioning and no substantial change in sound aversiveness. CI users reported a high level of implant satisfaction postoperatively. CONCLUSION: This study highlights the positive impact of cochlear implantation on auditory performance, communication, and subjective well-being. The CI-ICF protocol provides a holistic and comprehensive view of the evolution of CI outcomes.

Remote Check as a tele-health instrument for cochlear implant recipients: Analysis of impact and feasibility of application.

PURPOSE: The number of cochlear implant (CI) surgeries is growing over time, with the risk of overloading CI centers in the post-surgical management. Telemedicine is a possible solution to address this phenomenon. Remote Check (RC) is an application that is specific for CI recipients monitoring. The aim of this study is to evaluate the feasibility of application, potential economic impact and patients' acceptance of RC. METHODS: The study is retrospective investigation, data on clinical, audiological features (from remote and on-site evaluation), and satisfaction surveys of 66 consecutive patients were collected; costs required for RC and for on-site evaluations were recorded as well. RESULTS: One hundred and ninety RC sessions were completed by the patients (2.88 sessions per patient). RC and on-site audiometry significantly correlated except for the 500 Hz frequency. Estimated costs for the Italian National Health System for RC review and on-site evaluations were 1.32€ and 3.49€ per minute, respectively. High satisfaction for RC was reached in 91 % of patients. CONCLUSION: RC revealed to be a reliable, cost-effective and well accepted tool in CI monitoring. This study preliminarily supports the hypothesis that RC could be a valid instrument to reduce CI management overload in the outpatient clinic.

Radioclinical Assessment of Posterior Tympanotomy Difficulties during Ordinary Cochlear Implantation: A Prospective Case-Series Study.

OBJECTIVES: This study proposes a preoperative radiologic scoring system for predicting posterior tympanotomy (PT) and mastoidectomy-associated difficulties during cochlear implantation (CI). STUDY DESIGN: It was a prospective case-series study. SETTINGS: The included CI surgeries were performed at tertiary referral institutions from October 2022 to April 2023. SUBJECTS: We included 73 CI candidates performed via the PT approach. INTERVENTION: The proposed radiologic score, composed of 13 items, was fulfilled and evaluated before each CI surgery. MAIN OUTCOME MEASURE: We correlated this score with the intraoperative difficulty and surgical duration. RESULTS: The operation was straightforward in 42 patients with a score of 3.87 ± 1.72 and challenging in 31 patients with a score of 10.66 ± 1.73. The radiologic score was strongly correlated with the surgical difficulty and duration (p < 0.0001). CONCLUSIONS: Our proposed radiologic score was a valid, reliable, and precise tool to predict intraoperative difficulty during cochlear implantation. Chorda-facial angle was the strongest predictor, significantly affecting the difficulty, surgical duration, and preoperative radiologic score. A score equal to or more than 7.5 was expected to be associated with surgical difficulty.

A Comparison of Montreal Cognitive Assessment Scores among Individuals with Normal Hearing and Cochlear Implants.

OBJECTIVES: The Montreal Cognitive Assessment (MoCA) is a cognitive screening tool that has 4 of 10 test items heavily dependent on auditory input, potentially leaving hearing-impaired (HI) individuals at a disadvantage. Previous work found that HI individuals scored lower than normal-hearing (NH) individuals on the MoCA, potentially attributed to the degraded auditory signals negatively impacting the ability to commit auditory information to memory. However, there is no research comparing how cochlear implant (CI) recipients perform on the MoCA relative to NH and HI individuals. This study aimed to (1) examine the effect of implementing three different hearing-adjusted scoring methods for a group of age-matched CI recipients and NH individuals, (2) determine if there is a difference between the two groups in overall scores and hearing-adjusted scores, and (3) compare scores across our CI and NH data to the published HI data for all scoring methods. We hypothesized that (1) scores for CI recipients would improve with implementation of the hearing-adjusted scoring methods over the original method, (2) CI recipients would score lower than NH participants for both original and adjusted scoring methods, and (3) the difference in scores between NH and CI listeners for both adjusted and unadjusted scores would be greater than that reported in the literature between NH and HI individuals due to the greater severity of hearing loss and relatively poor spectral resolution of CIs. DESIGN: A total of 94 adults with CIs and 105 adults with NH were initially enrolled. After age-matching the two groups and excluding those who self-identified as NH but failed a hearing screening, a total of 75 CI participants (mean age 61.2 y) and 74 NH participants (mean age 58.8 y) were administered the MoCA. Scores were compared between the NH and CI groups, as well as to published HI data, using the original MoCA scoring method and three alternative scoring methods that excluded various auditory-dependent test items. RESULTS: MoCA scores improved for all groups when two of the three alternative scoring methods were used, with no significant interaction between scoring method and group. Scores for CI recipients were significantly poorer than those for age-matched NH participants for all scoring methods. CI recipients scored better than the published data for HI individuals; however, the HI group was not age matched to the CI and NH groups. CONCLUSIONS: MoCA scores are only partly affected by the potentially greater cognitive processing required to interpret degraded auditory signals. Even with the removal of the auditory-dependent items, CI recipients still did not perform as well as the age-matched NH group. Importantly, removing auditory-dependent items significantly and fundamentally alters the test, thereby reducing its sensitivity. This has important limitations for administration and interpretation of the MoCA for people with hearing loss.

A Guinea Pig Model Suggests That Objective Assessment of Acoustic Hearing Preservation in Human Ears With Cochlear Implants Is Confounded by Shifts in the Spatial Origin of Acoustically Evoked Potential Measurements Along the Cochlear Length.

OBJECTIVES: Our recent empirical findings have shown that the auditory nerve compound action potential (CAP) evoked by a low-level tone burst originates from a narrow cochlear region tuned to the tone burst frequency. At moderate to high sound levels, the origins shift to the most sensitive audiometric regions rather than the extended high-frequency regions of the cochlear base. This means that measurements evoked from extended high-frequency sound stimuli can shift toward the apex with increasing level. Here we translate this study to understand the spatial origin of acoustically evoked responses from ears that receive cochlear implants, an emerging area of research and clinical practice that is not completely understood. An essential step is to first understand the influence of the cochlear implant in otherwise naive ears. Our objective was to understand how function of the high-frequency cochlear base, which can be excited by the intense low-frequency sounds that are frequently used for objective intra- and postoperative monitoring, can be influenced by the presence of the cochlear implant. DESIGN: We acoustically evoked responses and made measurements with an electrode placed near the guinea pig round window. The cochlear implant was not utilized for either electrical stimulation or recording purposes. With the cochlear implant in situ, CAPs were acoustically evoked from 2 to 16 kHz tone bursts of various levels while utilizing the slow perfusion of a kainic acid solution from the cochlear apex to the cochlear aqueduct in the base, which sequentially reduced neural responses from finely spaced cochlear frequency regions. This cochlear perfusion technique reveals the spatial origin of evoked potential measurements and provides insight on what influence the presence of an implant has on acoustical hearing. RESULTS: Threshold measurements at 3 to 11 kHz were elevated by implantation. In an individual ear, thresholds were elevated and lowered as cochlear implant was respectively inserted and removed, indicative of "conductive hearing loss" induced by the implant. The maximum threshold elevation occurred at most sensitive region of the naive guinea pig ear (33.66 dB at 8 kHz), making 11 kHz the most sensitive region to acoustic sounds for guinea pig ears with cochlear implants. Conversely, the acute implantation did not affect the low-frequency, 500 Hz thresholds and suprathreshold function, as shown by the auditory nerve overlapped waveform. As the sound pressure level of the tone bursts increased, mean data show that the spatial origin of CAPs along the cochlear length shifted toward the most sensitive cochlear region of implanted ears, not the extended high-frequency cochlear regions. However, data from individual ears showed that after implantation, measurements from moderate to high sound pressure levels originate in places that are unique to each ear. CONCLUSIONS: Alterations to function of the cochlear base from the in situ cochlear implant may influence objective measurements of implanted ears that are frequently made with intense low-frequency sound stimuli. Our results from guinea pigs advance the interpretation of measurements used to understand how and when residual acoustic hearing is lost in human ears receiving a cochlear implant.

Estimating the United States Patient Population Size Meeting Audiologic Candidacy for Cochlear Implantation.

OBJECTIVE: This study aimed to estimate the size of the United States candidacy pool meeting expanded Center for Medicare Services criteria for cochlear implantation. STUDY DESIGN: Retrospective cross-sectional. SETTING: Tertiary care center. METHODS: Preimplantation audiometric data from 486 patients seen at a single academic medical center were collected retrospectively and used to generate a predictive model of AzBio score based on audiometric pure tone thresholds. This model was then used to estimate nationally representative cochlear implantation (CI)-candidacy using pure tone averages included in the National Health and Nutrition Examination Survey. Qualitative and quantitative analyses were performed. RESULTS: We find that the estimated prevalence of CI candidacy in individuals 65 years of age or older is expected to more than double with a change in the CI candidacy criteria from ≤40% to ≤60% (from 1.42%, 95% confidence interval [1.33, 1.63] to 3.73% [2.71, 6.56]) on speech testing. We also found the greatest absolute increase in candidacy in the 80+ age group, increasing from 4.14% [3.72, 5.1] of the population meeting the ≤40% criteria to 12.12% [9.19, 18.35] meeting the ≤60% criteria. CONCLUSION: The United States population size meeting expanded CMS audiologic criteria for cochlear implantation is estimated to be 2.5 million adults and 2.1 million age 65 or older. Changing the CI candidacy criteria from ≤40% to ≤60% on CI testing has the greatest effect on the eligible patient population in the >65-year-old age group. The determination of utilization rates in newly eligible patients will require further study.

Why Do Cochlear Implant Candidates Defer Surgery? A Retrospective Case-Control Study.

OBJECTIVE(S): Despite undergoing thorough cochlear implant (CI) candidacy evaluation and counseling, some patients ultimately elect against implantation. This study sought to identify patient-related and socioeconomic factors predicting CI deferral. METHODS: A retrospective study of adult (≥18 years old) CI candidates presenting between 2007 and 2021 at a tertiary academic CI center was performed. The primary outcome was device implantation. Data collected included age, gender, hearing status, race, zip code of residence, median family income (MFI), distance traveled from the CI center, marital status, employment status, and insurance status. Multivariable binary logistic regression was performed to identify predictors of implantation. RESULTS: A total of 200 patients qualifying for CI were included, encompassing 77 adults deferring surgery (CI-deferred) and 123 consecutive adults electing for surgery (CI-pursued). Age, gender, hearing status, insurance type, employment status, distance from the implant center, and MFI were comparable between the groups (p > 0.05). Compared to CI-pursued patients, CI-deferred patients were more likely to be non-Caucasian (24.7% vs. 9.8%, p = 0.015) and unmarried (55.8% vs. 38.2%, p = 0.015). On multivariable logistic regression, older age (OR 0.981, 0.964-0.998, p = 0.027), African American race (OR 0.227, 0.071-0.726, p = 0.012), and unmarried status (OR 0.505, 0.273-0.935, p = 0.030) were independent predictors of implant deferral. CONCLUSION: This study demonstrates that increasing age at evaluation, African American race, and unmarried status are predictors for deferring CI surgery despite being implant candidates. These patients may benefit from increased outreach in the form of counseling, education, and social support prior to undergoing CI surgery. LEVEL OF EVIDENCE: 3 - retrospective study with internal control group Laryngoscope, 134:2857-2863, 2024.

Investigating Deferral Rates in Cochlear Implantation: How Often Do Candidates Defer and Why?

OBJECTIVE: Evaluate the rate at which cochlear implant (CI) candidates decline surgery and identify associated factors. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary referral center. PATIENTS: Four hundred ninety-three CI candidates from July 1989 to December 2020 with complete demographic and socioeconomic data. INTERVENTIONS: Diagnostic. MAIN OUTCOME MEASURES: Age, sex, race, marital and employment status, median household income percentile, distance-to-CI-center, and residence in a medically underserved county. RESULTS: Of the 493 CI candidates included, 80 patients (16.2%) declined surgery. Based on chart checking, the most common reason patients did not receive the implant was due to loss of follow-up (38%). African American patients were 73% less likely to undergo implantation compared with White patients (odds ratio [OR], 0.27 [0.11-0.68]; p = 0.005). Asian patients were 95% less likely to undergo implantation (OR, 0.05 [0.009-0.25]; p = 0.0003) compared with White patients. For every 1-year age increase, patients were 4% less likely to undergo implantation (OR, 0.96 [0.94-0.98]; p < 0.0001) and for every 10-year age increase, the patients were 33% less likely. Compared with their single counterparts, married patients were more likely to undergo implantation (OR, 1.87 [1.12-3.15]; p = 0.02). No differences were observed when comparing implanted and nonimplanted CI candidates in sex, employment status, distance-to-CI-center, or median family income percentile. A χ2 test of independence showed no association between receiving CIs and living in medically underserved counties ( χ2 = 2; N = 493; 0.3891; p = 0.53). CONCLUSIONS: Not infrequently, CI candidates decline surgery. Although demographic factors (race, age, and marital status) were associated with the cochlear implantation decision, socioeconomic factors (median family income and residence in a medically underserved community) were not. Perhaps cultural components of a patient's race have a larger impact on whether or not the patients get implanted.

Temporal Trends in Early Pediatric Cochlear Implantations in California from 2018 to 2020.

OBJECTIVE: To characterize the demographics of children receiving cochlear implantations, identify factors associated with delayed implantations, and trend these factors over time. DESIGN: Retrospective cross-sectional study. SETTING: Healthcare Cost and Utilization Project California State Ambulatory Surgery Database for calendar years 2018-2020. PATIENTS: Children 5 years or younger undergoing cochlear implantation. INTERVENTIONS: Cochlear implantation. MAIN OUTCOMES MEASURES: The population-controlled number of cochlear implantations was calculated and stratified by race and insurance. Early implantation was defined as implantation at age 2 years or younger. A mixed-effects logistic regression model was generated to identify factors associated with early implantation and how that association changed from 2018 to 2020. RESULTS: The final cohort included 467 children. The number of implantations increased from 141 to 175 implants from 2018 to 2020 (24.1% increase); 229 (49.0%) children were implanted at 2 years or younger. Medicaid insurance was associated with decreased odds of early implantation (odds ratio, 0.18 [95% confidence interval, 0.15-0.23], p < 0.001); this association with Medicaid insurance was significant when stratified across all racial groups. The percentage of children with Medicaid who were implanted at 2 years or younger increased from 20.9 to 62.0% from 2018 to 2020. CONCLUSIONS AND RELEVANCE: Among children in California, socioeconomic factors, in particular public insurance, are correlated with age of cochlear implantation. These disparities improved significantly from 2018 to 2020. Further investigation into changes and initiatives in California during this time frame may aid in directing national efforts to improve pediatric cochlear implantation access.

An Investigation of the Impact of Expanding High-Deductible Health Plans on Patient Decision for Cochlear Implant Surgery and Postoperative Outcomes.

HYPOTHESIS: After the expansion of high deductibles, patients will delay cochlear implant (CI) surgery to the end of the year, and the risk of postoperative known risks will increase. BACKGROUND: The Affordable Care Act was associated with increased enrollment in high-deductible health plans (HDHPs), which resulted in rising health insurance deductibles. Health insurance plans can cover a patient's cost of healthcare once the deductible is met. Patients have been shown to be economic rational decision makers and make decisions based on cost rather than health. They wait for their deductible to be met, typically at the end of the year, then proceed to have costly care. The goal of this study was to evaluate the impact of rising health insurance deductibles on the rate and postoperative outcomes of cochlear implantation and to assess changes by the Tax Cuts and Jobs Act. METHODS: TriNetX was used to accumulate summary data on patients who obtained a CI between 2005 and 2022 at the beginning (quarter 1) and the end of the year (quarter 4) from the electronic medical records of 75 healthcare organizations. The trends in average rate of cochlear implantation and resultant postoperative known risks or complications were statistically evaluated. RESULTS: After expansion of HDHPs, the rate of cochlear implantation between quarter 4 (19 cases per year) and quarter 1 (17 cases/year) was similar (p = 0.18). For all patient groups, the case volume significantly increased. Between quarter 4 and quarter 1, postoperative tinnitus was more common in the beginning of the year (risk ratio, 0.68; 95% confidence interval, 0.46-0.99). CONCLUSIONS: The number of patients receiving CIs significantly increased despite the expansion of HDHPs. Tinnitus was a rare postoperative known risk in the beginning of the year. Patients are less likely concerned about cost of CI surgery because of the impact of hearing loss on quality of life.

Reliability and validity assessment of a survey: Measuring satisfaction with cochlear implant rehabilitation services for children in Jordan.

BACKGROUND: Assessing parental satisfaction with healthcare services is crucial, particularly for parents and their children, who are the primary recipients of these services. In the context of Arabic-speaking parents, there is a notable absence of survey instruments tailored to measure their satisfaction. This study seeks to address this gap by validating a survey designed to evaluate parental satisfaction with rehabilitation services (RSs) provided to Jordanian children who have received cochlear implants (CIs). METHODS: The study included 92 participants and followed a four-step methodology: 1) a literature review and expert input; 2) cognitive interviews, pilot testing, and test-retest reliability testing; 3) data collection; 4) validity and reliability assessments. RESULTS: The survey's validity was confirmed. Expert input and cognitive interviews improved content validity, and factor analysis established construct validity by revealing six factors explaining 82.33% of the variance in the survey scale. Convergent and discriminant validity were confirmed (composite reliability >0.7 and average variance extracted value >0.5). Cronbach's α exceeded 0.8 for each factor and reached 0.855 for the total scale. Survey results showed reliance on speech therapy and audiology, varied rehabilitation durations, and progress. Parents expressed overall satisfaction, particularly influenced by technical quality and efficacy/outcome dimensions. Parents' recommendations to enhance satisfaction with RSs included financial support, improved service accessibility, enhanced service delivery, specialized education, and increased public awareness. CONCLUSION: This study validates an Arabic satisfaction survey, emphasizing the significance of multidisciplinary, extended rehabilitation programs, skilled professionals, and positive outcomes. It emphasizes the necessity for improved access to specialized care and collaboration among healthcare, government, and media to shape parental perceptions of RSs. While the findings indicate overall satisfaction, they also reveal challenges faced by parents, highlighting the need for comprehensive support systems. These insights assist healthcare providers and policymakers in enhancing care quality and meeting the needs of CI children's families, thereby improving the RSs experience in Jordan.

A country-wide health policy in Chile for deaf adults using cochlear implants: Analysis of health determinants and social impacts.

BACKGROUND: Post-lingual deafness represents a critical challenge for adults' well-being with substantial public health burdens. One treatment of choice has been cochlear implants (CI) for people with severe to profound hearing loss (HL). Since 2018, Chile has implemented a high-cost policy to cover CI treatment, the "Ley Ricarte Soto" (LRS) health policy. However, wide variability exists in the use of this device. To date, no related study has been published on policy evaluation in Chile or other Latin American countries. OBJECTIVES: This study aimed to evaluate the impact of the LRS policy on the treatment success and labour market inclusion among deaf or hard of hearing (DHH) adults using CI. We examined and characterised outcomes based on self-reports about treatment success and occupation status between 2018 and 2020. DESIGN: We performed a prospective study using hospital clinical records and an online questionnaire with 76 DHH adults aged >15 who had received CIs since the introduction of the LRS policy in 2018. Using univariate and multivariate regression models, we investigated the relationship between demographic, audiological, and social determinants of health and outcomes, including treatment success for social inclusion (International Outcome inventory for Hearing Aids and CIs assessment: IOI-HA) and occupation status for labour market inclusion. RESULTS: Our study showed elevated levels of treatment success in most of the seven sub-scores of the IOI-HA assessment. Similarly, around 70% of participants maintained or improved their occupations after receiving their CI. We found a significant positive association between treatment success and market inclusion. Participants diagnosed at younger ages had better results than older participants in both outcomes. Regarding social determinants of health, findings suggested participants with high social health insurance and a shorter commute time to the clinic had better results in treatment success. For labour market inclusion, participants with high education levels and better pre- CI occupation had better post-CI occupation status. CONCLUSIONS: In evaluating the LRS policy for providing CIs for DHH adults in Chile, we found positive effects relating to treatment success and occupation status. Our study supports the importance of age at diagnosis and social determinants of health, which should be assessed by integrating public services and bringing them geographically closer to each beneficiary. Although evidence-based guidelines for candidate selection given by the LRS policy might contribute to good results, these guidelines could limit the policy access to people who do not meet the requirements of the guidelines due to social inequalities.

National Trends in Cochlear Implantation Across the Department of the Defense: A Case for Inclusion as a General Otolaryngology Core Competency.

OBJECTIVE: With ongoing national expansions in cochlear implantation (CI) candidacy criteria, more patients qualify for CI today than ever before. Among US veterans and military service members, the prevalence of qualifying degrees of hearing loss secondary to occupational noise exposure exceeds the general population. The primary aim of the current work was to evaluate CI trends across the military health system. STUDY DESIGN: Database review. SETTING: Military and civilian practices. PATIENTS: Department of Defense (DoD) beneficiaries who underwent CI. MAIN OUTCOME MEASURES: CI rates between 2010 and 2019. RESULTS: A total of 3,573 cochlear implant operations were performed among DoD beneficiaries from 2010 to 2019. A majority of patients (55%) were older than 64 years, with the next most commonly implanted age group being 0 to 4 years of age (14%). From 2010 to 2019, annual CI increased at a rate of 7.9% per year for all implantation over the study period ( r = 0.97, p < 0.0001); there was a statistically significant difference of this rate compared with tympanoplasty, which was used as a reference procedure (rate, -1.9%; p = 0.03). This trend was similar for beneficiaries implanted both in military (11.9% per year, r = 0.77, p = 0.009) and civilian facilities (7.7% per year, r = 0.96, p < 0.0001); there was no statistically significant difference between the annual growth rates of these groups ( p = 0.68). CONCLUSIONS: Although the number of devices implanted is rapidly increasing among DoD beneficiaries, reported national utilization rates remain low. This disparity likely exists in the general public, considering the aging demographic in the West and continual expansions in US Federal Drug Administration labeling. These data suggest that widespread expansion of the procedure to general otolaryngology practices will be required to meet current and future demands for CI. For this reason, CI should be considered for "key indicator" designation among residency training programs.

Investigating Socioeconomic Barriers to Cochlear Implantation.

OBJECTIVE: To explore socioeconomic disparities in cochlear implant evaluation (CIE) referrals and cochlear implantation. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary referral academic center. METHODS: Adult patients (n = 271) with an audiogram performed between 2015 and 2019 with a pure-tone average of at least 60 dB and word recognition score of 60% or less in the better-hearing ear or no word recognition score performed were included to determine if socioeconomic factors influenced the rate of referral to CIE and cochlear implantation. RESULTS: There were 122 insured patients referred to CIE where 84 were considered cochlear implant (CI) candidates and 73 were implanted. In multivariate regression analysis, non-English-speaking patients were referred to CIE at lower rates ( p < 0.01) than English-speaking patients. Patients who met the CI candidacy criteria with private insurance ( p = 0.03) or Medicare with private insurance supplement ( p = 0.03) had higher rates of cochlear implantation than those with Medicare or Medicaid. Of the uninsured patients (n = 22), 3 were referred to CIE and 2 were considered CI candidates. No uninsured patients received a CI. CONCLUSIONS: Primary language spoken was associated with a disparity in rates of CIE referral. Insurance type did influence rate of cochlear implantation once patients completed CIE and were considered CI candidates. Additional research is needed to implement strategies for more inclusive treatment.
