A workable approach to the identification of neonatal hearing impairment
Insights
Early identification of infant hearing impairment is crucial. A regional screening program using Brain Stem Electric Response Audiometry (BERA) effectively identifies hearing loss in newborns, enabling timely intervention.
Area of Science:
- Pediatric Audiology
- Neonatal Screening
- Hearing Impairment Diagnosis
Background:
- Infant hearing impairment requires early detection for optimal developmental outcomes.
- Mass screening programs are essential for identifying hearing loss in newborns.
- The American Hearing Research Foundation initiated a regional infant screening program in Illinois.
Purpose of the Study:
- To implement and evaluate a comprehensive infant hearing screening program.
- To establish early identification of hearing impairment in newborns.
- To improve long-term quality of life for children with hearing loss.
Main Methods:
- Utilized a High-Risk Register for the general newborn population.
- Conducted hearing screening in Intensive Care Nurseries.
- Employed Brain Stem Electric Response Audiometry (BERA) for electrophysiologic confirmation.
- Integrated immediate remediation and/or habilitation services.
Main Results:
- Brain Stem Electric Response Audiometry (BERA) demonstrated accuracy and sensitivity in assessing infant auditory thresholds.
- The program successfully identified hearing impairment in over 250 infants and young children.
- BERA, following neonatal screening, proved effective for early hearing loss detection.
Conclusions:
- Early identification of hearing impairment is achievable through a structured screening and diagnostic approach.
- Timely intervention before critical developmental periods significantly impacts a child's quality of life.
- The Illinois regional program serves as a model for effective infant hearing loss identification and management.
Abstract:
The American Hearing Research Foundation has developed a regional Infant Screening Program in the state of Illinois, designed to meet the vital need for early identification of hearing impairment on a mass scale. The four major components of the program include: 1. Application of the High Risk Register to the general newborn population, 2. Hearing Screening in the Intensive Care Nursery, 3. Electrophysiologic confirmation with Brain Stem Electric Response testing and 4. Subsequent and immediate remediation and/or habilitation. Brain Stem Electric Response Audiometry (BERA) has been shown to be an accurate and sensitive clinical tool for obtaining auditory thresholds in infants from birth. At the Donald T. Forsythe Otologic Laboratory in Mercy Hospital, Chicago, IL, over 250 infants and young children have been tested in a controlled study with BERA to establish or rule-out the diagnosis of hearing impairment. The use of BERA preceded by screening of a refined neonatal population has proven to be an effective method of early identification. The goals of the program are: 1. To identify hearing impaired children prior to passage of the critical periods, 2. To medically or surgically classify and treat and/or auditorily habilitate, and 3. To ultimately improve the quality of life of the child born with hearing impairment.
