 A deaf child will not be able to acquire speech and spoken language.



Language  hearing society
          integration and inclusion programs
          better education and employment prospects
          better self-realization
          enhanced quality of life

Facts and Figures
Hearing loss without NHS is recognized when the child is already 2 to 3 y. old.



                       The first year of life is the most
                        important for language

                         Carol Flexer (quote):

History
                        Milestones

•   1944 – recognition of need to determine hearing
    abilities by the age of one (Ewing & Ewing)
•   1940s – introduction of audiometers
•   Since 1964 – Marion Downs
•   1969 – establishment of the Joint Committee on
    Infant Hearing
•   1978 – David Kemp measuring otoacoustic
    emissions
•   1986 - Automated Auditory Brainstem Response
    Equipment becomes available
•   1998 - The first European Consensus
    Conference, Milano

History
                               The European Consensus Statement
•   Permanent childhood hearing impairment (1) (PCHI) is a serious public health problem affecting at least one baby in
    one thousand. Intervention is considered to be most successful if commenced in the first few months of life.
    Therefore, identification by screening at or shortly after birth has the potential to improve quality of life and
    opportunities for those affected.
•   Effective programmes of intervention are well established.
•   Methods for identification of PCHI in the neonatal stage are now accepted clinical practice. They are effective and
    can be expected to identify at least 80% of cases of PCHI whilst incorrectly failing 2-3% of normally hearing babies in
    well-controlled programmes.
•   Neonatal testing in maternity hospitals is more effective and less expensive than behavioural screening
    conventionally carried out at 7-9 months.
•   Targeting neonatal testing on only the 6-8% of babies at increased risk (2) of PCHI reduces costs but cannot identify
    more than 40-50% of cases. Targeted neonatal hearing screening in parallel with 7-9 month behavioural testing is
    more expensive and less effective than universal neonatal screening.
•   Hearing screening in the neonatal period cannot identify acquired or progressive hearing loss occurring
    subsequently. Surveillance methods are required to identify those cases, which may be 10-20% of all permanent
    childhood hearing impairment.
•   Risks associated with neonatal hearing screening include anxiety from false positive results and possible delayed
    diagnosis from false negative results, but these risks are acceptable in view of the expected benefits.
•   Neonatal hearing screening should be considered to be the first part of a programme of habilitation of hearing
    impaired children, including facilities for diagnosis and assessment.
•   A system of quality control is an essential component of a neonatal hearing screening programme. Quality control
    includes training of personnel and audit of performance. The person responsible for quality control should be
    identified.
•   Although the healthcare systems in Europe differ from country to country in terms of organisation and funding,
www.monika-
    implementation of neonatal hearing screening programmes should not be delayed. This will give new European
    citizens greater opportunities and better quality of life into the next millenium.

Overview of the Worldwide Situation
                The situation is very heterogeneous

                             USA:
                             90% of newborns screened
                             Germany:
                             Law passed in 2009,
                               responsibility lies with
                               federal lands
                             Loss to follow-up varies within
                               2 to 50%.

Definition and Quality of Screening
                  by the World Health Organization

•   The main purpose of
    screening is the initial
    identification of
    undistinguishable
    diseases and disorders
    by using adequate
    methods. Screening
    allows selecting from
    the whole population
    patients with a high
    probability.

Definition and Quality of Screening
                The American Academy of Paediatrics, 1999


•   Sensitivity, specificity and easy use to
    minimize referrals
•   Undetectability by clinical parameters
•   Available interventions to correct the
    conditions detected by screening
•   Early screening, detection and intervention
    result in improved outcome
•   Acceptable cost-effective range.

                   NHS meets all criteria


•   Deafness is the most frequent disorder in
    newborns.
•   Screening for congenital hearing loss is non-
    invasive, objective and not expensive.
•   Adequate equipment to measure OAE and
    AABR is available.
•   Leading manufacturers state that the
    sensitivity of their equipment is 99% and the
    specificity 97%.

The baby is screened on the 2nd or 3rd day after birth while still in
    hospital
   retest
   referral to a diagnostic center for in-depth analysis
   parents are informed of the results
   a second screening before school should be recommended

                    Jay Rubenstein (2004):


“In 20 years, an implant will be the treatment of choice
   for anyone with a hearing loss greater than 50 dB”




www.monika-
lehnhardt.net
Conclusions
     Universal screening for hearing loss must be obligatory for newborns

•   Universal screening for congenital hearing loss is
    feasible and cost-effective.
•   The success is dependent on sufficient educational
    effort for community professionals, commitment on
    the part of the programme planners and data
    systems.
•   One of the most decisive factors is counselling of
    parents in order to avoid loss to follow-up.
•   Pre-school screening is strongly advocated.

Conclusions
                       Martin Hyde (quote):




  “Infants cannot complain of lack of hearing and cannot seek
     intervention we would surely not deny ourselves. We can
     and we must do their complaining for them. Infants and
     families have a fundamental right to early and effective
     communication”

Universal neonatal hearing screening: obligatory, voluntary or not really necessary? - Dr. Dr. h. c. Monika Lehnhardt

  • 1. Universal Neonatal Hearing Screening Is it obligatory, voluntary or not really necessary? Dr. Dr. h.c. Monika Lehnhardt Founder of Lehnhardt Academy and Chairwoman of Prof. Ernst Lehnhardt-Foundation Yerevan - November 23rd 2010
  • 2. Facts and Figures •Hearing impairment is the most frequent disorder in newborns • 1-2 babies in 1000 are born deaf or severely hearing-impaired • another 2-4 suffer from moderate hearing loss www.monika- lehnhardt.net
  • 3. Facts and Figures •5000 deaf-born babies a year in the European Community • Another 5000-10000 require intervention Germany: 800-1200 babies Poland: 400-800 babies www.monika- lehnhardt.net
  • 4. Facts and Figures Armenia: 40-80 deaf-born babies a year • Currently there are 35 Cochlear Implant recipients in total • Waiting list • 1-2 Million EURO p.a. to treat all deaf-born www.monika- lehnhardt.net
  • 5. Facts and Figures A deaf child will not be able to acquire speech and spoken language. Language  hearing society  integration and inclusion programs  better education and employment prospects  better self-realization  enhanced quality of life www.monika- lehnhardt.net
  • 6. Facts and Figures Hearing loss without NHS is recognized when the child is already 2 to 3 y. old. The first year of life is the most important for language development! www.monika- lehnhardt.net
  • 7. Facts and Figures Normal hearing behaviour in a baby 0-3 months • is irritated by sudden loud noises • recognizes and calms to mother’s voice 3-6 months • begins to turn eyes or head to sounds • stops crying when spoken to • begins making vowel sounds www.monika- lehnhardt.net
  • 8. Facts and figures Normal hearing behaviour in a baby 6-9 months • looks for family members when her/his name is called • normally turns head towards sound • will respond to her/his name • responds to simple requests with gestures • uses voice to get your attention 9-12 months • understands “No”, “Bye, bye” • responds to soft sounds • looks at pictures when named • repeats simple sounds that we make • uses voice when playing alone www.monika- lehnhardt.net
  • 9. Facts and Figures Carol Flexer (quote): “Identification of newborn hearing loss should be considered a neuro- developmental emergency” www.monika- lehnhardt.net
  • 10. History Milestones • 1944 – recognition of need to determine hearing abilities by the age of one (Ewing & Ewing) • 1940s – introduction of audiometers • Since 1964 – Marion Downs • 1969 – establishment of the Joint Committee on Infant Hearing • 1978 – David Kemp measuring otoacoustic emissions • 1986 - Automated Auditory Brainstem Response Equipment becomes available • 1998 - The first European Consensus Conference, Milano www.monika- lehnhardt.net
  • 11. History The European Consensus Statement • Permanent childhood hearing impairment (1) (PCHI) is a serious public health problem affecting at least one baby in one thousand. Intervention is considered to be most successful if commenced in the first few months of life. Therefore, identification by screening at or shortly after birth has the potential to improve quality of life and opportunities for those affected. • Effective programmes of intervention are well established. • Methods for identification of PCHI in the neonatal stage are now accepted clinical practice. They are effective and can be expected to identify at least 80% of cases of PCHI whilst incorrectly failing 2-3% of normally hearing babies in well-controlled programmes. • Neonatal testing in maternity hospitals is more effective and less expensive than behavioural screening conventionally carried out at 7-9 months. • Targeting neonatal testing on only the 6-8% of babies at increased risk (2) of PCHI reduces costs but cannot identify more than 40-50% of cases. Targeted neonatal hearing screening in parallel with 7-9 month behavioural testing is more expensive and less effective than universal neonatal screening. • Hearing screening in the neonatal period cannot identify acquired or progressive hearing loss occurring subsequently. Surveillance methods are required to identify those cases, which may be 10-20% of all permanent childhood hearing impairment. • Risks associated with neonatal hearing screening include anxiety from false positive results and possible delayed diagnosis from false negative results, but these risks are acceptable in view of the expected benefits. • Neonatal hearing screening should be considered to be the first part of a programme of habilitation of hearing impaired children, including facilities for diagnosis and assessment. • A system of quality control is an essential component of a neonatal hearing screening programme. Quality control includes training of personnel and audit of performance. The person responsible for quality control should be identified. • Although the healthcare systems in Europe differ from country to country in terms of organisation and funding, www.monika- implementation of neonatal hearing screening programmes should not be delayed. This will give new European citizens greater opportunities and better quality of life into the next millenium. lehnhardt.net
  • 12. Overview of the Worldwide Situation The situation is very heterogeneous USA: 90% of newborns screened Germany: Law passed in 2009, responsibility lies with federal lands Loss to follow-up varies within 2 to 50%. www.monika- lehnhardt.net
  • 13. Definition and Quality of Screening by the World Health Organization • The main purpose of screening is the initial identification of undistinguishable diseases and disorders by using adequate methods. Screening allows selecting from the whole population patients with a high probability. www.monika- lehnhardt.net
  • 14. Definition and Quality of Screening The American Academy of Paediatrics, 1999 • Sensitivity, specificity and easy use to minimize referrals • Undetectability by clinical parameters • Available interventions to correct the conditions detected by screening • Early screening, detection and intervention result in improved outcome • Acceptable cost-effective range. www.monika- lehnhardt.net
  • 15. Definition and Quality of Screening NHS meets all criteria • Deafness is the most frequent disorder in newborns. • Screening for congenital hearing loss is non- invasive, objective and not expensive. • Adequate equipment to measure OAE and AABR is available. • Leading manufacturers state that the sensitivity of their equipment is 99% and the specificity 97%. www.monika- lehnhardt.net
  • 16. Definition and Quality of Screening How to organize screening The baby is screened on the 2nd or 3rd day after birth while still in hospital  retest  referral to a diagnostic center for in-depth analysis  parents are informed of the results  a second screening before school should be recommended www.monika- lehnhardt.net
  • 17. Definition and Quality of Screening Prerequisites for hospitals • All neonatal departments of hospitals are connected by Internet and deliver the data of their measurements to a central institution • Suitable software to ensure quick and reliable data transfer • Adequate training for the personnel that implements the screening test www.monika- lehnhardt.net
  • 18. Definition and Quality of Screening Parents are the key Parents are informed of the possible results and actions to be taken Family to family support is encouraged via modern ways of web-based communication (Internet, Skype and LiveOnline Rooms) to share knowledge and exchange experience www.monika- lehnhardt.net
  • 19. NHS is the First Step Only Hearing Aids • Rehabilitation should begin straight after the test, within the first 6 months of life • Hearing aids should be fitted and adaptive software supplied • Cochlear implantation should be suggested www.monika- lehnhardt.net
  • 20. NHS is the First Step Only Cochlear Implants • Quality • Reliability • Excellent service network • Surgical techniques that are less damaging and preserve residual hearing • Cosmetic appeal www.monika- lehnhardt.net
  • 21. NHS is the First Step Only Jay Rubenstein (2004): “In 20 years, an implant will be the treatment of choice for anyone with a hearing loss greater than 50 dB” www.monika- lehnhardt.net
