10 Why is Implementation of Newborn Hearing Screening Accelerating?
Improved Screening Techniques/Equipment Acceptance by Increased Number of Policy Makers Successful Programs Public Awareness/Demand

11 Why is Early Identification of Hearing Loss so Important?
Hearing loss occurs more frequently than any other birth defect.

12 Rate Per 1,000 of Permanent Childhood Hearing Loss in UNHS Programs
Sample Prevalence Site Size Per 1000 Rhode Island (3/93 - 6/94) 16, Colorado (1/ /96) 41, New York (1/ /97) 69, Texas (1/94 - 6/97) , Hawaii (1/ /96) 9, New Jersey (1/ /95) 15,

13 Incidence per 10,000 of Congenital Defects/Diseases

14 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.

15 Reading Comprehension Scores of Hearing and Deaf Students
Grade Equivalents Age in Years Schildroth, A. N., & Karchmer, M. A. (1986). Deaf children in America, San Diego: College Hill Press.

16 Effects of Unilateral Hearing Loss
Normal Hearing Unilateral Hearing Loss Keller & Bundy (1980) Math (n = 26; age = 12 yrs) Language Peterson (1981) Math (n = 48; age = 7.5 yrs) Language Bess & Thorpe (1984) Social (n = 50; age = 10 yrs) Math Blair, Peterson & Viehweg (1985) (n = 16; age = 7.5 yrs) Language Math Culbertson & Gilbert (1986) (n = 50; age = 10 yrs) Language Social Average Results 0th 10th 20th 30th 40th 50th 60th Math = 30th percentile Percentile Rank Language = 25th percentile Social = 32nd percentile

17 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. Effect Size for Outcome Measure Less vs. More OME WISC-R Full Scale .62 Metropolitan Achievement Test Math .48 Reading .37 Goldman Fristoe Articulation .43 Teele, D.W., Klein, J.O., Chase, C., Menyuk, P., Rosner, B.A., and the Greater Boston Otitis media Study Group (1990).

18 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.

19 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. (July 1996). The effect of early identification on the development of deaf and hard-of-hearing infants and toddlers . Paper presented at the Joint Committee on Infant Hearing Meeting, Austin, TX.

22 Good work, but I think we might need just a little more detail right
Implementing Effective EHDI Programs out Then a miracle occurs Start Good work, but I think we might need just a little more detail right here.

23 Is the Glass Half Empty or 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

24 Status of Early Hearing Detection and Intervention (EHDI) in the United States
Diagnosis before 3 months Screening before 1 month Intervention before 6 months Medical Home Data Management and Tracking Program Evaluation and Quality Assurance Family Support!!

25 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

26 Typical UNHS Screening Protocols (example for 1,000 newborns)
Hearing Loss=3 Normal Hearing=7 Inpatient Screening Pass=920 Fail=80 Outpatient n=80 Diagnosis n=10 Pass=70 Fail=10 2 Stage OAE Hearing Loss=3 Normal Hearing=37 Diagnosis n=40 Inpatient Screening Fail=40 Pass=960 1 Stage AABR Diagnosis n=20 Inpatient Screening Pass=980 Fail=20 Hearing Loss=3 Normal Hearing=17 OAE / AABR 1 Stage

27 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

28 Purposes of an EHDI Data System
Research Program Improvement and Quality Assurance Screening Diagnosis Intervention Medical, Audiological and Educational

29 Rate Per 1000 of Permanent Childhood Hearing Loss in UNHS Programs
Sample Prevalence % of Refers Site Size Per with Diagnosis Rhode Island (3/93 - 6/94) 16, % Colorado (1/ /96) 41, % New York (1/ /96) 27, % Utah (7/ /94) , % Hawaii (1/ /96) 9, %

30 Tracking "Refers" is a Major Challenge
(continued) Initial Rescreen Births Screened Refer Rescreen Refer Rhode Island 53,121 52,659 5,397 4,575 677 (1/ /96) (99%) (10%) (85%) (1.3%) Hawaii 10,584 9,605 1,204 991 121 (1/ /96) (91%) (12%) (82%) (1.3%) New York 28,951 27,938 1,953 1,040 245 (1/96-12/96) (96.5%) (7%) (53%) (0.8%)

31 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

32 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 EHDI information management looks deceptively simple at first glance.

33 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 EHDI information management looks deceptively simple at first glance.

34 Efficiency of Early Hearing Detection and Intervention in a Statewide Evaluation
(6 mos.) (n=43,547) (n=46,771) (n=23,307) Inpatient Refer Rates (state average) % 85.5% 87.5% 10 most effective hospitals % 93.4% 93.7% 10 least effective hospitals % 63.4% 74.4% Outpatient completion (state average) % 67.1% 68.3% 10 most effective hospitals % 95.9% 94.7% 10 least effective hospitals % 52.9% % Reported Completion of Diagnostic 133 of of of 110* Evaluations (state average) % 43.4% 40% % of babies who complete Diagnostic of of of 41* Eval & have permanent hearing loss % 39.4% 29.3% Number of babies still “in process” *only 3 months worth of data

35 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

36 State Coordinator’s Ratings of Obstacles to Effective EHDI Programs
Serious or Extremely Serious Obstacle Shortage of qualified pediatric audiologists 49% Physicians don’t know enough about newborn hearing screening, diagnosis, and intervention % Unwillingness of third-party payers to reimburse for hearing screening %

37 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

38 Confirmation of Permanent Hearing Loss
35 Coplan (1987) 19 Eissman et al. (1987) 30 Gustason (1987) 30 Meadow-Orlans (1987) 24 Yoshinago-Itano (1995) 25 Stein et al. (1990) 31 Mace et al. (1991) 56 O'Neil (1996) 3 Johnson et al. (1997)* 3 Vohr et al. (1998)* 10 20 30 40 50 60 70 Average Age in Months

39 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

40 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

41 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)

44 What Is a Medical Home? A primary care physician provides care which is: Accessible Family-centered Comprehensive Continuous Coordinated Compassionate Culturally effective

45 EHDI and the Medical Home
Birthing Hospital Audiology Parent Groups Mental Health Primary Provider Child/Family ENT 3rd Party Payers Deaf Community Early Intervention Programs Genetics Services for Hearing Loss

46 Types of Hearing Loss Sensorineural versus Conductive versus Mixed Congenital versus Acquired (prelingual or post lingual) Progressive versus non-progressive Syndromic versus non-syndromic Familial versus sporadic

47 What Causes Hearing Loss? Congenital Hearing Loss
Environmental CMV meningitis rubella prematurity head trauma asphyxiation ototoxicity hyperbilirubin other infections Syndromic Alport Norrie Pendred Usher Waardenburg Branchio-oto-renal Jervell and Lange-Nielsen ~50% Congenital Hearing Loss ~30% ~50% Non-syndromic Autosomal dominant 21% Genetic Autosomal recessive 77% X-Linked ~70% ~1% ~1% Mitochondrial

48 Common Forms of Syndromic Hearing Loss
Syndrome Main Features (in addition to hearing loss) Alport Kidney problems Branchio-oto-renal Neck cysts and kidney problems Jervell and Lange-Nielsen Heart problems Neurofibromatosis Type 2 Nerve tumors near the ear Pendred Thyroid enlargement Stickler Unusual facial features, eye problems, arthritis Usher Progressive blindness Waardenburg Skin pigment changes

49 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

50 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

51 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.
