Notes: αAll 56 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.” 44 jurisdictions used the revised definition for the 2015 HSFS. ¥Diagnosed before 3 months is based on the 55 jurisdictions who were able to report complete data for this measure (for formula, see data notes below).

Data Notes
  • HSFS data reflects 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.
  • This data is subject to change if additional states and/or territories report data for year 2015.
  • 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.” Includes instances where infant’s families were Unable to be contacted or Unresponsive, and Unknown cases.

Explanation of 2015 Calculations

Documented Hearing Screening

(based on data from 56 states & territories)

Percent Screened
3,796,042 (# screened) / 3,866,820 (occurrent births reported by EHDI programs) x 100 = 98.2%

  • Percent Screened (excluding infant deaths & parental refusals)
    3,796,042 (# screened) / 3,844,630 (occurrent births excluding infant deaths & parental refusals) x 100 = 98.7%

    3,624,044 (# pass before 1 month + # not pass before 1 month) / 3,796,042 (# screened)
     x 100 = 95.5%

Percent Not Passing final / most recent hearing screening
64,978 (# not pass) / 3,796,042 (# screened) x 100 = 1.7%

No Documented Hearing Screening

(based on data from 56 states & territories)
