____________________

• WHY
• All available results (scientific and clinical)
  point out that the earlier the intervention the
  better the outcomes.
• EHDI systems are becoming the standard of care
  worldwide

 EHDI programmes in the European
area_____________________________________________
____________________

• Universal hearing screening is mandated - or
  supported - by central health authorities, in a
  number countries, or regions Austria, Belgium
  (Flanders), Croatia, England, Lithuania,
  Luxembourg, Netherlands, Poland, laenders in
  Germany, a number of Regions in Italy and Spain.

2004 State EHDI Survey NCHAM National Ctr for
Hearing Assessment and Management During the
first quarter of 2004, state Early Hearing
Detection and Intervention (EHDI) coordinators
were asked to complete a survey about their
program

• SCREENING (1)
• Percentage of babies born (3rd quarter 2003) in
  your state screened before leaving the hospital?
• 89.72 of all babies being screened
• 91.62 excluding states 80 (CA, IA OH)
• Birthing facilities
• Total 3602
• Minimum 7 (RI)
• Maximum 350 (CA)

• SCREENING (2)
• Birthing facilities doing UNHS (i.e., gt 90 of
  all births) at the end of December 2003 
• Total 3120
• Range 6 263
• Weighted percentages
• 86.62 of all birthing facilities doing UNHS
• 90.88 excluding states 80 (CA, KS, NY, TN,
  WA)

• REFERRALS
• Percentage of the referrals
• 5.57 - 47 States responding
• 3.52 - Excluding outliers
• 1 (10 states) and
• gt 10 (3 states)
• No response or "unknown" 4 states

• DIAGNOSIS
• Hearing status confirmed by 3 months of age
•  
• 55.09 36 states responding
• 53.80 Excluding outliers 5 (3 states) and
  90 (5 states)
• No response or "unknown" 15 states

EARLY INTERVENTION who began appropriate
early intervention by 6 months of age 48.68
who began appropriate early intervention after 6
months of age 19.66 for which early
intervention status is unknown 32.19 (No
response 15 states) N.B. of those identified
with permanent hearing loss, but not all those
who didnt pass the screening have been diagnosed!

• Early Hearing Detection and Intervention Programs
  are becoming the standard of care in an
  increasing number of countries
• Screening models have been receiving much
  attention during the past decade BUT still there
  is a long way to go for protocols and minimum
  requirements

HOW THE OPTIMAL MODEL FOR UNIVERSAL NEWBORN
HEARING SCREENING DOES NOT EXIST

36
Critical issues - Protocols ______________________
___________________________________________

• Properties of an ideal screening device
• Robust and reliable automatic detection algorithm
• Built-in automatic calibration (to control
  stimulus levels) for both AAOEs and AABR
• Maximum flexibility to cope with the variety of
  screening conditions mother-side, nursery,
  NICU.
• Insensitivity to background noise
• Maximum flexibility to cope with the changing
  screening criteria (standards are expected soon)

37
Screening Protocols ______________________________
___________________________________

• A two-track protocol?
• At-risk (NICU)() AABR-based
• Well-babies
• 1 or 2-stage AOAEsAABR
• 1-stage AABR
• () the incidence of PHL can be as high as 4 to
  6 is this screening??

38
COMBINING AOAEAABR

• Calibration of acoustic stimuli in the canal
• Lower referrals and false-positives
• Minimal parental anxiety
• Fewer diagnostic tests
• Fewer babies are lost
• More efficient management
• Auditory neuropathy can be identified early
