Summary
Swedish 4-year-olds failing initial hearing screening often normalize. Further testing revealed only 18% of referred children required specialist ENT referral, reducing unnecessary follow-ups.
Area of Science:
- Pediatrics
- Audiology
- Public Health
Background:
- Universal pure tone screening is standard for 4-year-olds in Sweden.
- High referral rates from initial screening may lead to over-referrals.
Purpose of the Study:
- To evaluate the effectiveness of a comprehensive oto-audiological assessment program.
- To reduce false positives and negatives in pediatric hearing referrals.
Main Methods:
- Children failing pure tone screening underwent audiometry and tympanometry.
- A 3-test program with 6-week intervals was implemented.
- Failure criteria included middle ear pressure < -150 mm H2O and hearing loss > 20 dB.
Main Results:
- Only 45% of referred children showed abnormalities at the first follow-up.
- 60% of initially abnormal children normalized during the 15-20 week program.
- Ultimately, only 18% of initially screened failures required ENT referral.
Conclusions:
- The comprehensive testing protocol effectively identifies children needing further evaluation.
- This approach significantly reduces over-referral rates from initial mass hearing screenings.
- Optimized screening protocols improve resource allocation in pediatric audiology.
