About the National Data
Data
Data Source: Early Hearing Detection and Intervention Hearing Screening and Follow-up Survey (EHDI/HSFS), CDC/NCBDDD
Baseline: 53.0 percent of infants with confirmed hearing loss were enrolled for intervention services no later than 6 months of age in 2017
Target: 62.9 percent
Numerator
Number of infants who are enrolled in intervention services by 6 months of age if they have confirmed hearing loss.
Denominator
Number of infants with confirmed hearing loss before 6 months of age.
Target-setting method
Percentage point improvement
Target-setting method details
Percentage point improvement from the baseline using Cohen's h effect size of 0.20.
Target-setting method justification
Trend data were evaluated for this objective, but it was not possible to project a target because the trend was moving away from the desired direction. A percentage point improvement was calculated using Cohen's h effect size of 0.2. This method was used because the objective was expected to move in the desired direction during the next decade and the Healthy People 2030 Workgroup Subject Matter Experts wanted to achieve a balance between an ambitious yet achievable goal.
Methodology
Methodology notes
Hearing screening procedures include otoacoustic emissions (OAE) and/or auditory brainstem response (ABR) tests.
History
Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.
1. Effect size h=0.2 was chosen to correspond with 20% improvement from a baseline of 50%.
