Trends in sociodemographic disparities of pediatric cochlear implantation over a 15-year period

Current Issues With Pediatric Cochlear Implantation

Cochlear implants (CIs) have demonstrated a clear functional benefit in children with severe-to-profound sensorineural hearing loss (SNHL) and thus have gained wide acceptance for treating deafness in the pediatric population. When evaluating young children for cochlear implantation, there are unique considerations beyond the standard issues addressed during surgery in adults. Because of advances in genetic testing, imaging resolution, CI technology, post-implant rehabilitation, and other factors, issues related to CI surgery in children continue to evolve. Such factors have led to changes in candidacy guidelines, vaccine requirements, and lowering of age requirement for surgery. In addition, differences in the anatomy and physiology of infants require special attention to ensure safety when operating on young children. This review summarizes these issues and provides guidance for surgeons treating children with SNHL.

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.

Evaluation of cost data associated with pediatric cochlear implantation (CI) throughout 2016-2021

INTRODUCTION

Cochlear Implants (CI) are a mainstay in the treatment of severe sensorineural hearing loss with proven cost-effectiveness and improved quality of life. However, costs associated with CI are variable. During the Covid-19 pandemic, elective surgeries decreased. The investigation into how the pandemic affected CI procedures, costs, and demographic utilization has not been elucidated.

METHODS

A retrospective cohort study using the Pediatric Health Information System® (PHIS) database, which consists of 50 children's hospitals, was performed. Regions were defined according to PHIS guidelines. We evaluated number of CIs, total charges and costs, Charge to Cost Ratios (CCR), demographic information, and subgrouped this analysis by region throughout 2016-2021. Charges were adjusted by CMS wage index for hospital location.

RESULTS

During the years of 2016-2021, there was a rising number of CIs every year except for 2020 which had a decrease, largely driven by the southern and midwestern regions. The median number of cases did not differ between the years. The median adjusted charges increased every year, but not significantly ($103,883-$125,394). The median CCR also did not differ throughout the years (2.7-3.1). Still, there was a larger interquartile range in 2021 (2.3-4.4) for the median CCR compared to all other years (2.1-3.8), particularly in the South. The percentage of white, non-Hispanic/Latino patients who underwent CI was larger in 2020-2021 (78-79.8 %) compared to 2016-2019 (73.3-77.5 %).

CONCLUSIONS

The number of CIs in 2020 was lower than in 2019 or 2021. The median CCR for CI procedures increased from 2016 to 2021 but not significantly. The range of CCR was larger in 2021 compared to the years prior, suggestive of cost shifting by some hospitals to offset the loss in revenue. There was a small but significant increase in white, non-Hispanic patients receiving CI in 2020 and 2021, suggestive of a socio-economic shift in care post pandemic.

Trends in Timing and Provision of Pediatric Cochlear Implant Care During COVID‐19

Objectives

To identify trends in timing of pediatric cochlear implant (CI) care during COVID-19.

Study Design

Retrospective cohort.

Setting

Tertiary care center.

Methods

Patients under 18 years of age who underwent CI between 1/1/2016 and 2/29/2020 were included in the pre-COVID-19 group, and patients implanted between 3/1/2020 and 12/31/2021 comprised the COVID-19 group. Revision and sequential surgeries were excluded. Time intervals between care milestones including severe-to-profound hearing loss diagnosis, initial CI candidacy evaluation, and surgery were compared among groups, as were the number and type of postoperative visits.

Results

A total of 98 patients met criteria; 70 were implanted pre-COVID-19 and 28 during COVID-19. A significant increase in the interval between CI candidacy evaluation and surgery was seen among patients with prelingual deafness during COVID-19 compared with pre-COVID-19 (µ = 47.3 weeks, 95% confidence interval [CI]: 34.8-59.9 vs µ = 20.5 weeks, 95% CI: 13.1-27.9; p < .001). Patients in the COVID-19 group attended fewer in-person rehabilitation visits in the 12 months after surgery (µ = 14.9 visits, 95% CI: 9.7-20.1 vs µ = 20.9, 95% CI: 18.1-23.7; p = .04). Average age at implantation in the COVID-19 group was 5.7 years (95% CI: 4.0-7.5) versus 3.7 years in the pre-COVID-19 group (95% CI: 2.9-4.6; p = .05). The time interval between hearing loss confirmation and CI surgery was on average 99.7 weeks for patients implanted during COVID-19 (95% CI: 48.8-150) versus 54.2 weeks for patients implanted pre-COVID (95% CI: 39.6-68.8), which was not a statistically significant difference (p = .1).

Conclusion

During the COVID-19 pandemic patients with prelingual deafness experienced delays in care relative to patients implanted before the pandemic.

How the Past Shapes the Future and What to Do About It: A Discussion at CI 2021 Virtual With Panelists: Teresa Caraway, Ph.D., C.C.C.-S.L.P.; Cliff Megerian, M.D.; Debara Tucci, M.D., M.S., M.B.A.; Peter Thomas, J.D.; Jason Wigand, Au.D

ABSTRACT

This report summarizes the highlights of a lively discussion between leaders in the cochlear implant (CI) field who also bring significant leadership experience at the practice and health system levels, as well as policy and research perspectives. The discussion revealed several areas in which established patterns of practice should be reconsidered to facilitate wider acceptance of the CI as part of an integrated continuum of hearing healthcare. The importance of continued innovation to advance outcomes, lower cost, and increase access was emphasized. Trends in healthcare funding, which increasingly reward quality at lower cost, will also challenge longstanding assumptions that have influenced program design. Proactive efforts that pursue consistent value in the episode of surgical care while establishing innovative delivery models for audiological and rehabilitation services are the best hope for a future of equitable access and expanding impact.

Association of Socioeconomic Characteristics With Receipt of Pediatric Cochlear Implantations in California

IMPORTANCE

Earlier cochlear implantation among children with bilateral severe to profound sensorineural hearing loss is associated with improved language outcomes. More work is necessary to identify patients at risk for delayed cochlear implantation and understand targets for interventions to improve cochlear implantation rates among children.

OBJECTIVE

To describe the demographics among children receiving cochlear implantations and variability in implantation rates in California and to investigate sociodemographic and parental factors associated with early pediatric cochlear implantation.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cross-sectional study was conducted using data from the Healthcare Cost and Utilization Project California State Ambulatory Surgery Database in calendar year 2018. Included patients were children aged 9 years old or younger undergoing cochlear implantation. Sociodemographic factors, location of treatment, and parental factors were collected. Data were analyzed from March through August 2021.

MAIN OUTCOMES AND MEASURES

Binary logistic regression was performed to investigate sociodemographic factors associated with early cochlear implantation (ie, before age 2 years). Geographic variability in pediatric cochlear implantation across hospital referral regions in California was described, and various parental factors associated with implantation before age 2 years were analyzed.

RESULTS

Among 182 children receiving cochlear implantations, the median (IQR) age was 3 (1-5) years and 58 children (31.9%) received implantations at ages 2 years or younger. There were 90 girls (49.5%) and 92 boys (50.5%), and among 170 children with race and ethnicity data, there were 27 Asian or Pacific Islander children (15.9%), 63 Hispanic children (37.1%), and 55 White children (32.4%). The risk of CI was significantly decreased among Black children compared with Asian or Pacific Islander children (relative risk [RR], 0.18 [95% CI, 0.07-0.47]; P = .001) and White children (RR, 0.24 [95% CI, 0.10-0.59]; P = .002) and among Hispanic children compared with Asian or Pacific Islander children (RR, 0.32 [95% CI, 0.21-0.50]; P < .001) and White children (RR, 0.42 [95% CI, 0.29-0.59; P < .001). Compared with private insurance, Medicaid insurance was associated with decreased odds of implantation at ages 2 years or younger (odds ratio [OR], 0.19 [95% CI, 0.06-0.64]; P = .007), and every 1 percentage point increase in maternal high school completion percentage in a given California hospital referral region was correlated with a 5-percentage point increase in percentage of cochlear implants performed at age 2 years or younger (b = 5.18 [95% CI, 1.34-9.02]; P = .008). There were no significant differences in rates of early implantation by race or ethnicity.

CONCLUSIONS AND RELEVANCE

This study found significant variability in pediatric cochlear implantation rates in California. These findings suggest that socioeconomic and parental factors may be associated with differences in access to early cochlear implantation and suggest the need to invest in initiatives to address barriers to appropriate and timely access to care.

Racial disparities in pediatric otolaryngology: current state and future hope

PURPOSE OF REVIEW

The current article reviews the current literature and selected sentinel papers on health disparities particularly relevant to the field of pediatric otolaryngology. The discussion will explore racial disparities in otologic and airway intervention areas, as well as general adenotonsillar disease management. Access to and quality of care will be examined, and disparate outcomes discussed.

RECENT FINDINGS

Growing published data demonstrate children from nonwhite backgrounds receive disparate specialty care in representative fields of pediatric otolaryngology.

SUMMARY

Racial disparities exist in specialty care pediatric otolaryngology. Such disparities should be viewed in the light of generational inequalities in the United States and the foundational inequities that perpetuate them. Parity in the delivery of such specialty care depends on recognizing our current state and intentional efforts to modulate the impact of such effectual factors.

Exploring Factors Responsible for Delay in Pediatric Cochlear Implantation

OBJECTIVE

To identify and characterize demographic and socioeconomic factors associated with delays in cochlear implantation (CI) in children.

STUDY DESIGN

Retrospective.

SETTING

Tertiary pediatric CI referral center.

PATIENTS

All patients under 18 years of age receiving CI between March 2018 and February 2020.

INTERVENTIONS

CI.

MAIN OUTCOME MEASURES

Primary outcome measures included age at implantation and time from hearing loss diagnosis and candidacy evaluation to CI.

RESULTS

Seventy-two patients were identified (44% women, average age at implantation 4.9 yr). Age at implantation was older in patients with public, rather than private, insurance (6.0 ± 0.8 yr versus 3.1 ± 0.7 yr, p = 0.007) and those from low-income areas (8.6 ± 7.6 yr versus 2.4 ± 3.0 yr, p = 0.007). Time between hearing loss diagnosis and implantation was longer in publicly insured patients (4.1 ± 0.6 yr versus 2.2 ± 0.5 yr, p = 0.014). Time between identification as a CI candidate and implantation was longer in publicly insured patients (721 ± 107d versus 291 ± 64 d, p = 0.001). Among children with congenital profound hearing loss, publicly insured patients continued to be older at implantation (1.9 ± 0.2 versus 1.0 ± 0.2 yr, p = 0.008). Latinx children were more often publicly insured whereas white children were more often privately insured (p < 0.05). Publicly insured patients had delays in the pre-CI workup, including, in no particular order, vestibular evaluation (621 ± 132 d versus 197 ± 67 d, p = 0.007), developmental evaluation (517 ± 106 d versus 150 ± 56 d, p = 0.003), speech evaluation (482 ± 107 d versus 163 ± 65 d, p = 0.013), and children's implant profile (ChIP) assessment (572 ± 107d versus 184 ± 59d, p = 0,002). On ChIP evaluation, concerns regarding educational environment and support were higher in Spanish-speaking children (p = 0.024; p = 2.6 × 10-4) and children with public insurance (p = 0.016; p = 0.002).

CONCLUSIONS

Disparities in access to CI continue to affect timing of pediatric cochlear implantation.

Socio-demographic profile and its influences on rehabilitation in children undergoing revision cochlear implantation - MERF experience

INTRODUCTION

Revision cochlear implant surgery (RIS) is an unusual and unfortunate event, but not an uncommon occurrence in today's time, with more and more children being implanted. It is accepted that a pediatric cochlear implant recipient may require one or two revision procedures during their lifetime. The indication of RIS can be due to a multitude of causes like trauma, device failure (hard failure or soft failure), infection at the implant site, electrode extrusion, device migration, magnet migration, and upgradation in the technology. Scenarios, where the child is deprived of hearing once again is worrisome for the family. And, they need financial and psychological assistance as well.

AIMS AND OBJECTIVES

(1) To scrutinize the socio-demographic profile of children who underwent RIS. (2)To profile the social, intellectual, and economic backgrounds of these families.

MATERIAL AND METHODS

A retrospective, observational, non-interventional, cohort study conducted at the Implantation otology department of Madras ENT Research Foundation (MERF), Chennai, Tamil Nadu, India.

DATA COLLECTION

(1) Detailed medical records of all the children who satisfied the inclusion criteria were reviewed.(2)This was followed up by a telephonic interview with the guardian of the consenting patients, to obtain further data based on a customized questionnaire.

SAMPLE SIZE

Of the 99 children who underwent RIS, 80 families consented to be part of the study.

STATISTICAL ANALYSIS

(1) Cause of revision implant surgery and Family system Risk estimate.(2) Correlation of sex, family system, patient non-compliance to habilitation, and residential area with RIS.(3) Correlation of the residential area of the patient with completion of 1-year habilitation.

RESULTS

A significant association observed between RIS and Sex (P = 0.03). A significant co-relation between patient non-compliance to habilitation and cause of revision implant surgery observed (P = 0.02). A significant co-relation was seen between residential area (Rural/Urban) and cause of RIS (P = 0.02). A statistically significant correlation seen with the residential area (Rural/Urban) of the child and completion of 1-year habilitation (P = 0.01). Uni-variant association was found between patients that have completed one year of habilitation, patient compliance, and modified Kuppuswamy Socio-Economic status.

CONCLUSION

The current data has aided in refining our institutional management protocols and predicting high-risk candidates who may need revision surgery in the future. Based on the data, all cochlear implantees and their families especially in the lower socio-economic strata, are now being meticulously educated about device care, the possible reasons for failures, and the importance of timely re-intervention.

Racial Disparities in Adult Cochlear Implantation

OBJECTIVE

To compare rates of cochlear implant referral and cochlear implantation across different races and to compare audiometric profiles of these patients.

STUDY DESIGN

Retrospective study.

SETTING

Academic tertiary care institution.

METHODS

Demographic and audiometric data were collected for patients who underwent cochlear implant evaluation or cochlear implantation from 2010 to 2020.

RESULTS

A total of 504 patients underwent cochlear implant evaluation; 388 met cochlear implant candidacy criteria, and 258 underwent implantation. Of the patients referred for cochlear implant evaluation, 68.5% were White, 18.5% were Black, and 12.3% were Asian, while the institution's primary service area is 46.9% White, 42.3% Black, and 7.7% Asian (P < .001). Black patients referred for cochlear implant evaluation had significantly worse hearing (mean pure-tone average [PTA] 84.5 dB, 26.1% word recognition) than White patients (mean PTA 78.2 dB, P = .005; 35.7% word recognition, P = .015) and Asians patients (mean PTA 77.9 dB, P = .04; 36.5% word recognition, P = .04). Black patients who underwent cochlear implant evaluation also had significantly worse AzBio scores than White patients: 24.5% versus 36.7% (P = .003). There was no significant difference in cochlear implantation rates between Black and White candidates (P = .06).

CONCLUSION

Black patients undergo cochlear implant evaluation and cochlear implantation at rates disproportionately lower than expected based on local demographics. In addition, Black patients have significantly worse hearing at the time of cochlear implant referral than White and Asian patients. Identifying and increasing awareness of these disparities are essential steps to improving cochlear implant access for potentially disadvantaged populations.

Sociodemographic Disparities in Pediatric Cochlear Implantation Access and Use: A Systematic Review

OBJECTIVES

Pediatric cochlear implantation (CI) is a multistep process, which exposes a healthcare system's potential weaknesses in ability to deliver timely care to deaf children. The current systematic review aims to determine the sociodemographic disparities that predict pediatric CI access and use among CI candidates and recipients across the world. We hypothesize that sociodemographic factors independently influence CI access and use within a given country.

STUDY DESIGN

Systematic review.

METHODS

A qualitative systematic review of PubMed, Scopus, Web of Science, and Embase databases was conducted for studies investigating the association of sociodemographic factors such as race, income, or insurance status with measures of pediatric CI access, such as age at CI or CI rate.

RESULTS

Out of 807 unique abstracts initially retrieved, 39 papers were included in the final qualitative systematic review. Twenty-seven thousand seven hundred and fifty-one CI-candidate children (6,623 CI recipients) were studied in 14 countries, with 21 studies conducted in the United States of America, published within the years of 1993 to 2020.

CONCLUSION

Some measures of CI access, such as age at CI and rates of CI, are consistently reported in the CI disparities literature while others such as access to rehabilitation services, willingness to undergo CI, and daily CI use are rarely measured. There are persistently reported disparities in a few key measures of CI access in a few populations, while there are some populations with a paucity of data. Future studies should delineate the nuances in the mechanisms of disparities by conducting multivariable analysis of representative sample data. Laryngoscope, 2021.

Sound Opportunities: Factors That Impact Referral for Pediatric Cochlear Implant Evaluation

OBJECTIVES/HYPOTHESIS

To identify barriers to and opportunities for referral among children who could be considered for cochlear implantation.

STUDY DESIGN

Retrospective review.

METHODS

Audiological and medical records were reviewed on all children who had diagnostic or hearing aid care through a statewide healthcare system over 5-year span to identify children who met newly established clinical cochlear implant (CI) referral criteria. Data were collected for 869 potential CI candidates regarding demographic, socio-economic, audiological, medical, and family factors that may influence referral. A binomial logistic regression was completed to investigate the potential contributions of these predictors toward referral for a CI evaluation.

RESULTS

Children who met traditional candidacy criteria of severe-to-profound bilateral hearing loss were referred at very high rates, while nontraditional candidates were referred less frequently. Factors influencing referral included race, age, insurance source, hearing thresholds, audiologist, physician, and family request.

CONCLUSIONS

Results suggest that bilateral traditional candidates are being referred at high percentages; however, current practices and trends in pediatric cochlear implantation should be shared with families and providers to increase referral rates for nontraditional candidates.  LEVEL OF EVIDENCE: 3 Laryngoscope, 2021.

Trends in Cochlear Implantation in Texas: An Exploration of Outpatient Discharge Data, 2010 to 2017

OBJECTIVES

To describe trends in cochlear implantation (CI) disparities in Texas using an all-payer database from 2010 to 2017.

METHODS

Texas Outpatient Surgical and Radiological Procedure Data, a public use data file, was accessed to analyze outpatient CI cases for Texas. Variables analyzed include patient age, sex, race/ethnicity, and insurance status. Population data from the American Community Survey generated CI utilization rates by patient demographic characteristics.

RESULTS

There were 6158 CI cases identified during the study period. The number of CI per year nearly doubled from 497 in 2010 to 961 in 2017. The majority of CI recipients were white (59.5%), male (51.9%), and privately insured (47.9%). All sub-populations statewide had more CI in 2017 compared to 2010, with the overall CI per 100 000 population increasing from 1.98 to 3.50 per 100 000 population. Patients over 75 demonstrated the greatest increase in the CI rate per 100 000 population, increasing from 4.60 in 2010 to 14.30 in 2017. Regarding race/ethnicity, all sub-populations noted an increase in the CI per 100 000 population, with white patients demonstrating the highest rate in 2017, at 4.36 CI per 100 000 population. Asian patients had a 502% increase in the CI rate (from 0.42 to 2.53), compared with 87.9%, 84.4%, and 69.2% increases for white, Black, and Hispanic populations, respectively.

CONCLUSIONS

CI became more widespread between 2010 and 2017, benefiting certain populations more than others. Black and Hispanic populations had lower CI per 100 000 population than their white peers, while patients >65 years of age accounted for the greatest increase in CI.

Racial and Insurance Inequalities in Access to Early Pediatric Cochlear Implantation

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 years of age. Even when insured by private insurance, black and Hispanic children were still less likely to be implanted before 2 years of age compared to white children with private insurance. Greater racial and insurance disparities existed in access to cochlear implantation before 1 year of age compared to implantation before 2 years of age.

Conclusion

Racial/ethnic and insurance disparities in pediatric cochlear implantation can be observed at the population level. To address these racial and insurance inequalities, a multidisciplinary care team is needed and priorities should be given to research endeavors and policy interventions that target these disparities.

Identifying Disadvantaged Groups for Cochlear Implantation: Demographics from a Large Cochlear Implant Program

Objective:

To identify demographic predictors of patients undergoing cochlear implantation evaluation and surgery.

Methods:

Consecutive adult patients between 2009 and 2018 who underwent cochlear implantation evaluation at a university cochlear implantation program were retrospectively identified to determine (1) cochlear implantation qualification rate and (2) pursuit of surgery rate with respect to age, gender, race, primary spoken language, marital status, insurance type, and distance to the cochlear implantation center.

Results:

A total of 823 cochlear implantation evaluations were analyzed. Overall, 76.3% of patients qualified for cochlear implantation and 61.5% of these patients pursued surgery. Age was the only independent predictor for cochlear implantation qualification, such that, for each year younger, the odds of qualifying for cochlear implantation increased by 2.5% (OR 0.98; 95% CI: 0.96-0.99). Age, race, marital status, and insurance type were each independent predictors of the decision to pursue surgery. The odds of pursuing surgery increased by 2.8% for each year younger (OR 1.03; 95% CI: 1.01-1.05). Compared to White patients, non-Whites were half as likely to pursue surgery (OR 0.47; 95% CI: 0.25-0.88). Single (OR 0.49; 95% CI: 0.26-0.94) and widowed patients (OR 0.46; 95% CI: 0.23-0.95) were about half as likely to pursue surgery as compared to married patients. Patients with military insurance were 13 times more likely to pursue surgery as compared to patients with Medicare (OR 13.0; 95% CI: 1.67-101.4).

Conclusion:

Younger age is an independent predictor for a higher cochlear implantation qualification rate, suggesting the possibility for delayed candidacy referral. Rate of surgical pursuit in qualified cochlear implantation candidates is lower for racial minorities, single and widowed patients, and older patients.

The Ethics of Cranial Nerve Implants

This overview of ethical and social issues pertaining to cranial nerve implants covers informed consent; risk-benefit assessments; security against unauthorized reprogramming or privacy intrusion; explantation; psychological side effects; equity and social distribution, cultural effects, for instance, on the deaf subculture; enhancement; and research ethics.
