Exploring Factors Responsible for Delay in Pediatric Cochlear Implantation

Factors that influence health service access in deaf and hard-of-hearing children: a narrative review

OBJECTIVES

Early diagnosis and intervention of deaf and hard-of-hearing (DHH) children leads to improved language and psychosocial outcomes. However, many child, parent and provider related factors can influence access to early intervention services, including hearing devices. This narrative review aims to explore factors that influence health service access in DHH children.

DESIGN

A systematic search was conducted to identify articles that explored factors that influenced health service access in DHH children in countries with Universal Newborn Hearing Screening, published between 2010 and 2022.

STUDY SAMPLES

Fifty-nine articles met the inclusion criteria for data extraction. This included 4 systematic reviews, 2 reviews, 39 quantitative and 5 mixed methods studies and 9 qualitative studies.

RESULTS

The identified factors were grouped into the following themes: (a) demographic factors, (b) family related factors, (c) child related factors, (d) factors specific to hearing devices, (e) service delivery, f) telehealth and (g) COVID-19.

CONCLUSION

This review provided a comprehensive summary of multiple factors that affect access to health services in DHH children. Psychosocial support, consistent clinical advice, allocation of resources to rural communities and use of telehealth are possible ways to address barriers and improve health service access.

Age and Incidence of Cochlear Implantation in the Pediatric Population With Congenital Bilateral Profound Hearing Loss

OBJECTIVES

The current study characterizes age and incidence of cochlear implantation among qualifying children with congenital bilateral profound hearing loss in the U.S.

STUDY DESIGN

Deidentified cochlear implantation data were acquired from prospectively collected patient registries from two cochlear implant (CI) manufacturers (Cochlear Americas and Advanced Bionics). Children <36 months old were assumed to have congenital bilateral profound sensorineural hearing loss.

SETTING

U.S. CI centers.

PATIENTS

Children <36 months old who received CIs.

INTERVENTIONS

Cochlear implantation.

MAIN OUTCOME MEASURES

Age at implantation and incidence.

RESULTS

A total of 4,236 children <36 months old underwent cochlear implantation from 2015 to 2019. The median age at implantation was 16 months (interquartile range, 12-24 mo) and did not change significantly during the 5-year study period (p = 0.09). Patients residing closer to CI centers (p = 0.03) and treated at higher-volume centers (p = 0.008) underwent implantation at a younger age. Bilateral simultaneous implantation increased from 38% to 53% of CI surgeries in 2015 and 2019, respectively. Children who received bilateral simultaneous CIs were younger compared with those receiving unilateral or bilateral sequential CIs (median, 14 versus 18 mo; p < 0.001). The incidence of cochlear implantation increased from 7,648 per 100,000 person-years in 2015 to 9,344 in 2019 (p < 0.001).

CONCLUSION

Although the incidence of pediatric CI recipients and the frequency of bilateral simultaneous implantation increased over the study period, age at implantation did not change significantly and far exceeded current Food and Drug Administration (9 mo) and American Academy of Otolaryngology and Head and Neck Surgery position statement (6-12 mo) guidelines.

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.
