Blindness separates people from things. Deafness separates people from people. --- Helen Keller
Why is Early Identification of Hearing Loss so Important? • Hearing loss is the most frequent birth defect.

Why is Early Identification of Hearing Loss so Important? • Hearing loss is the most frequent birth defect. • Undetected hearing loss has serious negative consequences.

Why is Early Identification of Hearing Loss so Important? • Hearing loss is the most frequent birth defect. • Undetected hearing loss has serious negative consequences. • There are dramatic benefits associated with early identification of hearing loss.
Yoshinaga-Itano, et al., 1996 Compared language abilities of hearing-impaired children identified 6 before 6 months of age (n = 46) with similar children identified after 6 months of age (n = 63). All children had bilateral hearing loss ranging from mild to profound, 6 and normally-hearing parents. Language abilities measured by parent report using the Minnesota 6 Child Development Inventory (expressive and comprehension scales) and the MacArthur Communicative Developmental Inventories (vocabulary). Cross-sectional assessment with children categorized in 4 different 6 age groups. Yoshinaga-Itano, C., Sedey, A., Apuzzo, M., Carey, A., Day, D., & Coulter, D. (July 1996).

Tremendous ProgressDuring the Last Decade • Less than 30 hospitals with UNHS in 1993; compared with more than 2000 today • More than 2 million babies are screened every year prior to discharge • 34 states have passed legislation related to newborn hearing screening
The Other Side of the Coin . . . . • 2,200 hospitals are not yet screening for hearing loss • Almost 2 million babies are NOT screened every year prior to discharge • Existing legislation is of variable quality • Only 9 states (accounting for 7% of the births) have implemented reasonable statewide programs • Follow-up rates are often alarmingly low • Some hospitals have unacceptably high referral rates
Status of EHDI Programs in the United States • Universal Newborn Hearing Screening
Universal Newborn Hearing Screening • With over half of all babies are screened prior to discharge, has newborn hearing screening become the standard of care? • There are hundreds of excellent programs - - - regardless of the type of equipment or protocol used • Many programs are still struggling with high refer rates and poor follow-up
Status of EHDI Programs in the United States • Universal Newborn Hearing Screening • Effective Tracking and Follow-up as a part of the Public Health System

Status of EHDI Programs in the United States • Universal Newborn Hearing Screening • Effective Tracking and Follow-up as a part of the Public Health System • Appropriate and Timely Diagnosis of the Hearing Loss
Audiological Diagnosis • Equipment and techniques for diagnosis of hearing loss in infants continues to improve • Severe shortages in experienced pediatric audiologists are delaying confirmation of hearing loss • Most states are having serious problems linking babies with diagnostic follow-up
Status of EHDI Programs in the United States • Universal Newborn Hearing Screening • Effective Tracking and Follow-up as a part of the Public Health System • Appropriate and Timely Diagnosis of the Hearing Loss • Prompt Enrollment in Appropriate Early Intervention
Early Intervention • Part C of IDEA is an under used resource • Services are generally quite good for babies with severe profound bilateral loss, but less adequate for babies with more moderate loss
