Summary
Universal newborn hearing screening is crucial. The Natus Algo 2 AABR demonstrated superior accuracy in identifying severe bilateral hearing loss in neonates compared to other devices, despite a longer test duration.
Area of Science:
- Neonatal audiology
- Medical device technology
- Public health
Background:
- Severe bilateral hearing loss affects 1-3/1000 full-term and 2-4/100 high-risk newborns.
- Universal hearing screening is recommended but technology choice remains a challenge.
Purpose of the Study:
- To compare the performance of three neonatal hearing screening devices: Natus Algo 2 AABR, Otodynamics EchoCheck TEE, and Biologic AuDx DPE.
- To evaluate accuracy and efficiency in identifying hearing loss in newborns.
Main Methods:
- A preliminary study involving thirty-two full-term newborns.
- Comparative analysis of test results from three distinct screening technologies.
Main Results:
- Natus Algo 2 AABR showed the highest pass rates (97% right, 91% left ear).
- Otodynamics EchoCheck TEE and Biologic AuDx DPE had pass rates between 31-56%.
- Natus test duration was 22.5 minutes; others ranged from 5.8-6.4 minutes.
Conclusions:
- The Natus Algo 2 AABR is favored for its accuracy in reflecting hearing loss incidence.
- Despite longer screening times, Natus offers a more reliable assessment for neonatal hearing loss detection.
