Otolaryngology–Head and Neck Surgery
Objective To evaluate the association between race/ethnicity and insurance status on the access to early cochlear implantation. Study Design Population-based retrospective analysis of pediatric cochlear implantation procedures. Setting State Ambulatory Surgery and Services Databases of Florida from 2005 to 2017. Methods All children aged 18 years or younger in the state of Florida undergoing cochlear implantation were identified. The outcome measures were access to early cochlear implantation (before 1 and 2 years of age). Descriptive and multivariate logistic regression analyses were conducted. Results Among 1511 pediatric cochlear implantation procedures with complete data, 65 (4.3%) procedures were performed by 1 year of age and 348 (23.0%) by 2 years of age. Black children (odds ratio [OR], 0.44; 95% CI, 0.28-0.70), Hispanic children (OR, 0.70; 95% CI, 0.52-0.94), and children with Medicaid (OR, 0.64; 95% CI, 0.48-0.84) were significantly less likely to be implanted before 2 yea...

The purpose of this study is to compare the timing and impact of hearing healthcare of rural and urban adults with severe hearing loss who use cochlear implants (CI). Cross-sectional questionnaire study. Tertiary referral center. Adult cochlear implant recipients. Data collected included county of residence, socioeconomic information, impact of hearing loss on education/employment, and timing of hearing loss treatment. The benefits obtained from cochlear implantation were also evaluated. There were 91 participants (32 from urban counties, 26 from moderately rural counties, and 33 for extremely rural counties). Rural participants have a longer commute time to the CI center (p < 0.001), lower income (p < 0.001), and higher percentage of Medicaid coverage (p = 0.004). Compared with urban-metro participants, rural participants with gradually progressive hearing loss had a greater time interval from the onset of hearing loss to obtaining hearing aid amplification (10 yr versus 5 yr...
Defining Disparities in Cochlear Implantation through the Social Determinants of Health
Seminars in Hearing
Hearing loss is a global public health problem with high prevalence and profound impacts on health. Cochlear implantation (CI) is a well-established evidence-based treatment for hearing loss; however, there are significant disparities in utilization, access, and clinical outcomes among different populations. While variations in CI outcomes are influenced by innate biological differences, a wide array of social, environmental, and economic factors significantly impact optimal outcomes. These differences in hearing health are rooted in inequities of health-related socioeconomic resources. To define disparities and advance equity in CI, there is a pressing need to understand and target these social factors that influence equitable outcomes, access, and utilization. These factors can be categorized according to the widely accepted framework of social determinants of health, which include the following domains: healthcare access/quality, education access/quality, social and community con...

Motivation: Severe to profound sensorineural hearing loss interferes with a child's development at the cognitive, linguistic, academic, and social levels. Since the beginning of the pediatric auditory rehabilitation program through cochlear implantation in the Ear, Nose, and Throat (ENT) Service of the Coimbra Hospital and University Center (CHUC), Portugal, its mentors defended the early diagnosis of hearing loss followed by timely intervention, and this was considered the starting point to optimize (re)habilitation through this method. Three decades or so later, recently we conducted this study to evaluate the performance of patients implanted in the initial phase of the cochlear implantation program. Objectives: The study aimed to evaluate the performance of individuals with severe to profound congenital hearing loss who underwent pediatric cochlear implantation and have used the cochlear implant for at least 25 years, to analyze the beneficial effect of early intervention in improving performance results. Methods: The study sample is composed of 31 individuals with severe to profound congenital hearing loss and no other comorbidities, divided into two groups (Group 1: age at implantation was under 3 years; Group 2: age at implantation was over 3 years). All 31 subjects were evaluated at 15, 20, and 25 years of cochlear implant (CI) use with a comprehensive set of tests. In addition, data were collected regarding the academic level of each participant. The results of both groups were compared to find out if there is an effect of age at implantation on auditory performance, and if there is an improvement in the performance with CI over time (15, 20, and 25 years of use). Results: The results show that there is a positive effect, with statistical significance, of early implantation on auditory performance, and telephone use. In both groups, there is an increase in performance over time, but it tends to stabilize after 20 years of CI use. Discussion and conclusion: The results obtained in this work support the importance of early intervention in patients with severe to profound hearing loss who are cochlear implant users and show that CI is an effective and reliable method in the treatment of these patients, contributing to their improved socioeducational integration, and that the benefits last over time.
Trends in Hearing
While the majority of cochlear implant recipients benefit from the device, it remains difficult to estimate the degree of benefit for a specific patient prior to implantation. Using data from 2,735 cochlear-implant recipients from across three clinics, the largest retrospective study of cochlear-implant outcomes to date, we investigate the association between 21 preoperative factors and speech recognition approximately one year after implantation and explore the consistency of their effects across the three constituent datasets. We provide evidence of 17 statistically significant associations, in either univariate or multivariate analysis, including confirmation of associations for several predictive factors, which have only been examined in prior smaller studies. Despite the large sample size, a multivariate analysis shows that the variance explained by our models remains modest across the datasets ([Formula: see text]–0.21). Finally, we report a novel statistical interaction indic...
Duration of Eligibility Prior to Cochlear Implantation
Otology & Neurotology, 2017
Objective: The objective is to determine if eligibility (as defined as the duration of severe to profound hearing loss before cochlear implantation [CI]) has changed over the 30 years since Food and Drug Administration approval. Data Sources: English-language, peer-reviewed articles, theses, and trial data available through PubMed and Cochrane Library databases up until and including May 31, 2016. Study Selection: One thousand six unique articles were identified. Prospective studies that reported duration of severe/ profound hearing loss before CI in adult patients were included. Retrospective studies, reviews, meta-analyses, articles reporting pediatric or mixed data, hybrid/electroacoustic CI, and articles from centers outside the United States were excluded. Seventyone studies met inclusion criteria and were included for analysis. Data Extraction: Contributing authors independently reviewed included studies for data validity and applicability. Data Synthesis: Metaregression was used to assess the relationship between the year of publication and duration of hearing loss. To account for a possible age effect, a second model was estimated including mean age at the time of study as a covariate. Conclusion: A positive association between study year and the duration of hearing loss before implantation was found showing a 0.28-year increase in the duration of hearing loss for every increasing study year. Contrary to conventional assumption, duration of eligibility for CI appears to be increasing. Though the reasons for this are not clear, current strategies to increase both awareness and access to CI seem to be falling short.
Factors Affecting Early and Late Cochlear Implantation
International Tinnitus Journal, 2022
Objectives: This study aimed to describe the factors affecting early and late cochlear implantation. Materials and Methods: A total of 159 patients from the Hospital Canselor Tuanku Muhriz (HCTM) Cochlear Implant Programme were recruited in this retrospective cross-sectional study. All paediatric Cochlear Implant (CI) recipients with pre-lingual deafness were included in this retrospective study. The study was conducted from January 2019 until December 2020. The pre-lingual cochlear implant recipients' data were analysed based on demographics and interval from diagnosis to hearing aid fitting and implantation. The association between the dependent variables with early and late cochlear implantation was compared. Results: A total of 83 (52%) patients were female. Chinese race constituted most of the patients, which was 90/159 (57%). The majority were from middle-income families (M40); 89 (56%). The most common aetiology of Hearing Loss (HL) was idiopathic; 139 (87%), followed by intrauterine infections, which comprised of congenital CMV; 8 (5%) and congenital Rubella; 1 (1%) and nonspecific intrauterine infection 2 (1%). The relationship between the universal neonatal hearing screening and the interval between diagnosis to implantation was significant (p=0.033). Other variables were not significant. Conclusion: UNHS was a significant factor contributing to early and late implantation. The median age of diagnosis of hearing loss was 18 months (interquartile range; 15); the age of CI was 34 months (interquartile range; 24); the interval from diagnosis to hearing aid was 2 months (interquartile range; 5), and the interval from diagnosis to CI was 16 months (interquartile range; 14).
Cochlear implantation in different socioeconomic groups - bursting the myth
International Journal of Pediatric Otorhinolaryngology, 2020
Cochlear implantation does wonders for children suffering from severe to profound hearing loss, especially when the child is less than 12 months of age. However, most studies indicate that detection and implantation are done well beyond that age, owing to poor socioeconomic status, parental education, and income. Taking into account The Chief Minister's Comprehensive Health Insurance Scheme in Tamil Nadu, which provides cochlear implantation free of cost, this study aims to describe ages at presentation and nutritional factors among different socioeconomic classes. Methods: A randomized retrospective comparative study was done between two groups of children based on the socioeconomic status of the family. Group A included children with a parental income of less than Rs. 72,000 and the cost of surgery covered by the Tamil Nadu Chief Minister's Comprehensive Health Insurance Scheme and group B included children with a parental income of more than 72,000 and the cost of surgery covered by the family. Three parameters were considered and compared-the age at presentation to the hospital for diagnosis and management and the weight and hemoglobin. The results were computed, and statistical analysis done. Results: There was a negligible difference between the age at presentation between the two groups with the mean age for children belonging to group A being 2.906563 and the mean age for children belonging to group B being 3.540625. Weight among the two groups showed a significant difference with a p-value of 0.023664 at p < 0.05. The difference in hemoglobin values was found to be insignificant, with mean values being 11.0375 g/ dl and 11.7375 g/dl for groups A and B respectively. Conclusion: This study has concluded sufficient awareness among different strata of society, despite economical differences, over cochlear implant programs owing to government initiatives of educating people and supporting them with necessary health benefits. Tamil Nadu, as a responsible state of a developing nation, has been proactive in ensuring the accessibility and reach of the health care system in this regard.

Clinical and Social Outcomes of Cochlear Implantation in Older Prelinguals
Journal of Audiology and Otology
Background and Objectives: Cochlear implantation in late implanted prelinguals necessitates a complex decision-making process for clinicians and patients due to the uncertainty of achieving adequate benefit in auditory and speech perception. This study longitudinally evaluated clinical and social outcomes of prelingually deaf children with implantation in their late childhood.Subjects and Methods: A total of 113 (49 females and 64 males) participants, with an age range of 5-15 years, were assessed for the pre-implant parameters such as hearing loss etiology, aided responses, anatomical aspects, and psychological evaluation. The Category of Auditory Performance, Speech Awareness Threshold, Speech Reception Threshold, and Speech Discrimination Score were administered to assess the patient’s auditory skills. Further, the Speech Intelligibility Rating scale was administered to evaluate the patient’s speech intelligibility at 3, 6, 9, 12, 18, and 24 months post-surgery. Subjectively perc...
