Improved Screening Techniques/Equipment Acceptance by Policy Makers Why is Implementation of Newborn Hearing Screening Accelerating? Increased Number of Successful Programs Public Awareness/Demand
Why is Early Identification of Hearing Loss so Important? Hearing loss occurs more frequently than any other birth defect.

Why is Early Identification of Hearing Loss so Important? Hearing occurs more frequently than any other birth defect. Undetected hearing loss has serious negative consequences.

Effects of Mild Fluctuating Conductive Hearing Loss Teele, et al., 1990 194 children followed prospectively from 0-7 years. Days child had otitis media between 0-3 years assessed during normal visits to physician. Data on intellectual ability, school achievement, and language competency individually measured at 7 years by "blind" diagnosticians. Results for children with less than 30 days OME were compared to children with more than 130 days adjusted for confounding variables.

Why is Early Identification of Hearing Loss so Important? Hearing loss occurs more frequently than any other 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 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, and normally-hearing parents. Language abilities measured by parent report using the Minnesota Child Development Inventory (expressive and comprehension scales) and the MacArthur Communicative Developmental Inventories (vocabulary). Cross-sectional assessment with children categorized in 4 different age groups. Yoshinaga-Itano, C., Sedey, A., Apuzzo, M., Carey, A., Day, D., & Coulter, D.

Good work, but I think we might need just a little more detail right here. Implementing Effective EHDI Programs Then a miracle occurs out Start
Half full? More than 2.5 million babies are screened every year prior to discharge Less than 30 hospitals with UNHS in 1993; compared with almost 2500 today 37 states have passed legislation related to newborn hearing screening Or half empty? 1,500 hospitals are not yet screening for hearing loss Almost 1.5 million babies are NOT screened every year prior to discharge Existing legislation is of variable quality Follow-up rates are often alarmingly low Some hospitals have unacceptably high referral rates Is the Glass Half Empty or Half Full?
Status of Early Hearing Detection and Intervention (EHDI) in the United States Screening before 1 month Diagnosis before 3 months Intervention before 6 months Medical Home Data Management and Tracking Program Evaluation and Quality Assurance Family Support!!
Status of EHDI Programs in the US: 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

Options for Developing an EHDI Patient/Data Management System Develop your own Modify an existing system, for example electronic birth certificate, or heelstick data management system Purchase an existing system
Can EHDI Data Management be Combined with Heelstick? Both do initial screening of babies in the nursery prior to hospital discharge Both do outpatient screening for many babies Poor follow-up is biggest challenge for hearing screening Heelstick programs extremely successful with follow-up Infrastructure for Heelstick follow-up already exists
Issues to be Resolved Before Combining EHDI with Heelstick Follow-up Systems Recording results of EHDI on heelstick form is only the beginning Timing and procedures of data collection/entry are quite different for EHDI Electronic transfer of data from screening equipment to data form Availability of staff with expertise in EHDI issues to do follow-up Hospital staff need timely access to data Costs of modifying data entry/ reporting systems and duplicate data entry

State Coordinators Ratings of Obstacles to Effective EHDI Programs Serious or Extremely Serious Obstacle Shortage of qualified pediatric audiologists49% Physicians dont know enough about newborn hearing screening, diagnosis, and intervention 41% Unwillingness of third-party payers to reimburse for hearing screening 28%
Status of EHDI Programs in the US: Audiological Diagnosis Equipment and techniques for diagnosis of hearing loss in infants continues to improve Severe shortages in experienced pediatric audiologists delays confirmation of hearing loss State coordinators estimate only 56.1% receive diagnostic evaluations by 3 months of age

Status of EHDI Programs in the US: Early Intervention Current system designed to serve infants with bilateral severe/profound losses--- but, majority of those identified have mild, moderate, and unilateral losses Part C of IDEA is severely under utilized State Coordinators estimate: – Only 53% of infants with hearing loss are enrolled in EI programs before 6 months of age –Only 31% of states have adequate range of choices for EI programs
Who is Eligible for Part C Services? Child has a profound, permanent sensorineural hearing loss in both ears (PTA>100 dB) Child has a profound, permanent sensorineural hearing loss in one ear (PTA>100dB), but normal hearing in the other ear Child has a moderate, permanent sensorineural hearing loss in both ears (PTA=55dB) Child has a mild, permanent sensorineural hearing in both ears (PTA=35dB) Child has a mild, fluctuating conductive hearing loss (PTA=35dB) in both ears due to otitis media (ear infections)

Benefits of Genetic Testing for Hearing Loss Determine the chances of hearing loss in subsequent children Avoid unecessary (and often costly) tests such as electroretinograms, temporal bone imaging, and electrocardigrams Anticipate potential health problems –Monitoring for myopia and early retinal detachment for Stickler syndrome –Renal examinations can identify kidney problems in BOR –Vitamin A therapy may be beneficial in slowing retinal degeneration in child with Usher syndrome –Treatment of children with Jervell and Lange-Nielsen syndrome can minimize cardiac complications Dispel misinformation and offer emotional support by allaying parental guilt
Connexin 26 A protein responsible for intracellular communication (transfer of ions between the hair cells in the cochlea and their support cells) Responsible for 20-30% of all congenital hearing loss Several different mutations 35delG is found in 2-3% of all Caucasians of European descent 167delT is found in 5% of Ashkenazi Jewish population Usually recessive, occasionally dominant Almost always results in hearing loss that is : Congenital Severe-profound Non-progressive Non-syndromic
Susceptibility to Aminoglycoside Ototoxicity mitochondrial mutation A1555G in the rRNA gene in combination with exposure to aminoglycoside antibiotics results in rapid onset of hearing loss prevalent in Chinese and other oriental ethnic groups but has also been found in Caucasians, Greeks, etc.

Take Home Messages Deceptively simplethe devil is in the details EHDI is more than screening Medical Home is where the action is Thoughtful, ongoing, self appraisal Youre not alone
