Notes: α All 57 states and territories responded to all parts of the survey Respondents had the option to either use the revised definition or previous version for the field “Parents/Family Contacted but Unresponsive.” 43 jurisdictions used the revised definition for the 2017 HSFS.

Percent Screened for Hearing Loss by Different Denominators (US., 2008 - 2017)
  • Screened (based on EHDI-reported births): # screened / occurrent births reported by EHDI programs x 100
  • Screened (excluding Refusals/Infant Deaths): # screened / occurrent births, excluding infant deaths & parental refusals x 100
Hearing Status of Infants Not Passing Hearing Screening (U.S., 2017) N = 62,859
Documented Intervention Status of Infants with Hearing Loss (U.S., 2017) Total w. Hearing Loss = 6,537
Data Notes
  • Hearing Screening and Follow-up Survey data reflect information that states and territories have reportedly documented without estimation. As a result, data reported by CDC EHDI may differ from other sources.
  • Some respondents only provided partial data (e.g., hearing screening data only). As a result, the number of reporting states and territories and denominators varies for some of the data sections.
  • These data are subject to change if additional states and/or territories report data for year 2017.
  • In Process: Respondents were advised that to be reported in this category, each infant must have been seen for diagnostic testing at least one time and have a follow-up appointment already scheduled.
  • LFU (Loss to Follow-up) / LTD (Loss to Documentation): Sub group of “No Documented Diagnosis / Undetermined” and “No Intervention Services / Undetermined.” Includes cases where infants’ families were Contacted but Unresponsive, Unable to Contact, and Unknown.
