Insights
Sociodemographic factors like low birth weight, minority race, and lack of insurance are linked to missed follow-up appointments after newborn hearing screening (NBHS). Addressing these disparities is crucial for ensuring timely hearing care for all infants.
Area of Science:
- Public Health
- Pediatrics
- Genetics
Background:
- Universal newborn hearing screening (NBHS) is a critical component of early hearing detection and intervention (EHDI) programs globally.
- Despite high screening rates, a significant number of infants referred for further testing or intervention are lost to follow-up.
- Identifying factors contributing to this loss is essential for improving EHDI program effectiveness.
Approach:
- A systematic review and meta-analysis were conducted following PRISMA guidelines.
- Databases searched included PubMed, Scopus, and CINAHL from inception through December 2021.
- Included studies contained sociodemographic data for infants referred from NBHS, comparing follow-up adherence rates.
Key Points:
- Analysis of 169,238 infants across 19 studies revealed significant sociodemographic predictors of missed follow-up.
- Infant factors associated with non-adherence include low birth weight, minority racial status, rural residence, and lack of insurance.
- Maternal factors linked to missed follow-up include low educational attainment, young maternal age, unmarried status, and maternal smoking.
Conclusions:
- Both infant and maternal sociodemographic characteristics significantly impact follow-up compliance after NBHS referrals.
- Targeted interventions addressing identified sociodemographic barriers are necessary.
- Collaboration between healthcare providers and policymakers is vital to ensure equitable access to newborn hearing care and timely interventions.
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.
