Expanding the Role of Educational Audiologists After a Failed Newborn Hearing Screening: A Quality Improvement Study

Examining Barriers to Early Hearing Diagnosis

PURPOSE

Many factors create barriers for early hearing detection and intervention (EHDI), especially those related to unfavorable social determinants of health (SDOH). The primary aim of this study was to evaluate diagnostic timing of infants at risk for congenital hearing loss in consideration of known barriers. Understanding the specific barriers to early diagnosis can inform interventions to improve timeliness of diagnosis and subsequent habilitation.

METHOD

A retrospective chart review was completed for infants referred for diagnostic audiologic testing at a tertiary urban-setting Children's Hospital from 2018 to 2021. After exclusion criteria were applied, 1,488 infants were included in the analysis. Various factors were recorded from electronic medical records including those specific to SDOH. Time to diagnosis was derived and compared across five factors of interest that have previously been shown to impact diagnostic timeline, including (a) insurance type, (b) race/ethnicity, (c) presence of middle ear dysfunction at first auditory brainstem response (ABR), (d) proximity to diagnostic center, and (e) diagnostic timing before and during/after the COVID-19 pandemic.

RESULTS

Across the study time period, 77% of infants referred for diagnostic testing had confirmed diagnosis by the EHDI benchmark of 3 months. Analysis of time to diagnosis across factors of interest revealed no clinically significant differences for insurance type, race/ethnicity, proximity to diagnostic center, or timing in reference to the COVID-19 pandemic. Presence of middle ear dysfunction on first ABR was found to significantly protract final diagnostic timing.

CONCLUSIONS

Although some known barriers for EHDI can be universal, other factors may have a differential impact on an infant's timeline to diagnosis based on their specific location, which can interact differently with additional known barriers. Understanding local challenges will serve to better guide programs in implementing facilitators that will address their specific needs for improved outcomes.

The CPT1A Arctic variant: perspectives of community members and providers in two Alaska tribal health settings

Newborn screening in Alaska includes screening for carnitine palmitoyltransferase 1A (CPT1A) deficiency. The CPT1A Arctic variant is a variant highly prevalent among Indigenous peoples in the Arctic. In this study, we sought to elicit Alaska Native (AN) community member and AN-serving healthcare providers' knowledge and perspectives on the CPT1A Arctic variant. Focus groups with community members and healthcare providers were held in two regions of Alaska between October 2018 and January 2019. Thematic analysis was used to identify recurring constructs. Knowledge and understanding about the CPT1A Arctic variant and its health impact varied, and participants were interested in learning more about it. Additional education for healthcare professionals was recommended to improve providers' ability to communicate with family caregivers about the Arctic variant. Engagement with AN community members identified opportunities to improve educational outreach via multiple modalities for providers and caregivers on the Arctic variant, which could help to increase culturally relevant guidance and avoid stigmatization, undue worry, and unnecessary intervention. Education and guidance on the care of infants and children homozygous for the CPT1A Arctic variant could improve care and reduce negative psychosocial effects.

Sociodemographic Factors Affecting Loss to Follow-Up After Newborn Hearing Screening: A Systematic Review and Meta-Analysis

OBJECTIVE

Universal newborn hearing screening (NBHS) has been widely implemented as a part of early hearing detection and intervention (EHDI) programs worldwide. Even with excellent provider knowledge and screening rates, many infants do not receive definitive hearing testing or intervention after initial screening. The objective of this study was to identify sociodemographic factors contributing to loss of follow-up.

DATA SOURCES

PubMed, Scopus, and CINAHL.

REVIEW METHODS

Per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the databases were searched from the date of inception through December 28, 2021. Studies containing sociodemographic information on patients who were referred to NBHS were included. Meta-analysis of odds ratios (ORs) was performed comparing rates of sociodemographic variables between patients adherent and nonadherent to follow-up.

RESULTS

A total of 169,238 infants from 19 studies were included. Low birth weight (OR 1.6 [95% confidence interval, CI 1.2-2.2, p < .001), racial minority (OR 1.4 [95% CI 1.2-1.6], p < .001), rural residence (OR 1.5 [95% CI 1.1-1.9], p = .005), lack of insurance (OR 1 [95% CI 1.4-2.5], p < .001), and public or state insurance (OR 1.7 [95% CI 1.2-4.2], p = .008) were associated with missed follow-up after referred NBHS. Associated maternal factors included low maternal education (OR 1.8 [95% CI 1.6-2.0], p < .001), young maternal age (OR 1.5 [95% CI 1.5-1.6], p < .001), unmarried maternal status (OR 1.5 [95% CI 1.1-1.9], p = .003), and current or former maternal smoking status (OR 1.8 [95% CI 1.4-2.2], p < .001).

CONCLUSION

Both infant and maternal sociodemographic factors influence follow-up compliance after referred NBHS. Focused efforts should be made by medical providers and policymakers to address these factors to ensure appropriate newborn hearing care and interventions are achieved.

Barriers to and Facilitators of Early Hearing Detection and Intervention in the United States: A Systematic Review

OBJECTIVES

Early hearing detection and intervention (EHDI) is guided by the 1-3-6 approach: screening by one month, diagnosis by 3 mo, and early intervention (EI) enrollment by 6 mo. Although screening rates remain high, successful diagnosis and EI-enrollment lag in comparison. The aim of this systematic review is to critically examine and synthesize the barriers to and facilitators of EHDI that exist for families, as they navigate the journey of congenital hearing loss diagnosis and management in the United States. Understanding barriers across each and all stages is necessary for EHDI stakeholders to develop and test novel approaches which will effectively reduce barriers to early hearing healthcare.

DESIGN

A systematic literature search was completed in May and August 2021 for empirical articles focusing on screening, diagnosis, and EI of children with hearing loss. Two independent reviewers completed title and abstract screening, full-text review, data extraction, and quality assessments with a third independent reviewer establishing consensus at each stage. Data synthesis was completed using the Framework Analysis approach to categorize articles into EHDI journey timepoints and individual/family-level factors versus system-level factors.

RESULTS

Sixty-two studies were included in the narrative synthesis. Results revealed that both individual/family-level (e.g., economic stability, medical status of the infant including middle ear involvement) and system-level barriers (e.g., system-service capacity, provider knowledge, and program quality) hinder timely diagnosis and EI for congenital hearing loss. Specific social determinants of health were noted as barriers to effective EHDI; however, system-level facilitators such as care coordination, colocation of services, and family support programs have been shown to mitigate the negative impact of those sociodemographic factors.

CONCLUSIONS

Many barriers exist for families to obtain appropriate and timely EHDI for their children, but system-level changes could facilitate the process and contribute to long-term outcomes improvement. Limitations of this study include limited generalizability due to the heterogeneity of EHDI programs and an inability to ascertain factor interactions.

Exploring the Stories of Parents' Experiences With Infant Hearing-Loss Screening and Diagnosis in the United States

OBJECTIVES

For the past 20 years, birthing hospitals in the United States have required newborns to undergo a hearing-loss screening before leaving the hospital. Since the initial newborn hearing screening mandates, there has been much outcome research documenting the successes and barriers of the programs. However, we know little about the experiences of their parents during the time between screening and diagnosis. We propose that elucidating the parents' experiences with newborn hearing-loss screening and diagnosis-via their own stories-is a first step toward understanding their varied experiences and has the potential to ultimately improve hearing healthcare for both children and their families. Thus, to better understand the early hearing screening and detection experience from hearing parents' perspectives, we asked the following research question: what are parents' experiences with their newborns' hearing-loss screening and diagnosis in the United States?

DESIGN

The present study employed a prospective, cross-sectional qualitative design. Specifically, we gathered stories from 13 hearing parents who each have a child born in the United States and diagnosed with hearing loss no later than 14 mo of age between the years of 2016 and 2020. We used thematic analysis to uncover common themes across parent narratives. Saturation was reached at interview no. 4; thus no further sampling was needed.

FINDINGS

Two major themes emerged from the data: (1) hearing healthcare experiences and (2) parents' early experiences during the period between their child's newborn hearing-loss screening and diagnosis. Subthemes were also uncovered. Three emergent subthemes related to health-care experiences included: (1) downplayed newborn hearing screening referrals, (2) clinician-centered care, and (3) medical expenses and health coverage. The three subthemes of the second theme were as follows: (1) parent-to-parent support, (2) "mom guilt," and (3) a new reality.

CONCLUSION

The present study's narrative accounts from parents about their infants' early hearing detection experiences revealed several, different subthemes that emerged from the same, mandated newborn experience in US families. These findings highlight important moments throughout the hearing-loss screening and detection process, which could benefit from more effective, family-centered hearing healthcare. This knowledge also facilitates the field's move toward improved education of future and current providers and regarding family-centered approach, which could address concerns and expectations of new parents at the very start of their newborns' hearing-loss journeys.

Barriers to Equity in Pediatric Hearing Health Care: A Review of the Evidence

PURPOSE

We review the evidence regarding barriers to hearing health care for children who are deaf or hard of hearing.

BACKGROUND

There are considerable data to suggest that hearing health care disparities constitute a major factor in loss to follow-up or documentation for children going through the Early Hearing Detection and Intervention process. Families are affected by a combination of factors underlying these disparities, resulting in delayed care and suboptimal developmental outcomes for children who are deaf or hard of hearing.

CONCLUSIONS

To address the socioeconomic, cultural, and linguistic inequities seen in the diagnosis and management of childhood hearing loss, pediatric audiologists and speech-language pathologists have a responsibility to provide culturally responsive practice to their individual clients and their families, as well as advocate for substantive changes at the policy level that impact their clients' daily lives.
