Screening for hearing impairment in early childhood
Summary
Early hearing screening for infant deafness in Jerusalem identified many cases, but a 70% detection rate is achievable with improved methods. Recommendations include screening at 7-10 months and expanding to toddlers.
Area of Science:
- Pediatrics
- Audiology
- Public Health
Background:
- Early detection of childhood deafness is crucial for intervention.
- Previous hearing screening efforts in the Jerusalem area were evaluated.
Purpose of the Study:
- To assess the effectiveness of a 5-year hearing screening program for infants.
- To identify optimal screening ages and methods for early deafness detection.
Main Methods:
- Screened approximately 27,000 infants aged 5-7 months (85% of the population).
- Utilized baby clinics for screening and an 'at risk' register.
- Followed up identified hearing-impaired children at audiology centers.
Main Results:
- Screening in baby clinics was economical and feasible but not perfect.
- Approximately 50% of 43 hearing-impaired children were identified within their first year.
- An optimized screening and follow-up process could achieve a 70% detection rate.
Conclusions:
- Hearing screening and 'at risk' registers are recommended for infants aged 7-10 months.
- Expanding screening to 2- to 3-year-old children is suggested for comprehensive early detection.
