Newborn Hearing Screening Results: A Comparison of the Vivosonic Aurix and Vivosonic Integrity G2 Automated Auditory Brainstem Response System
Today, newborn hearing screening (NBHS) is a test completed in many parts of the world. One of the most common methods for conducting NBHS is through an automated auditory brainstem response (AABR) hearing screening system. Time and resources dedicated to conducting NBHS are important factors to consider in any newborn hearing screening program. Therefore, equipment manufacturers are constantly looking to develop new technology to maintain and improve efficient NBHS testing procedures, test results, and ease of use with screening equipment. Vivosonic Inc. has recently developed new hardware for the Vivosonic Integrity system which is designed for use with both automated ABR screening and diagnostic ABR testing. Conventionally, separate equipment is required to complete ABR screening and diagnostic ABR. One benefit to combined hardware is that a newborn hearing screening program would only need to purchase one piece of equipment in order to be able to complete both hearing screening and diagnostic follow-up testing.
The purpose of this project was to validate that the newborn hearing screening result and screening performance using the newest Vivosonic Integrity G2 hardware is equivalent to or better than the current clinically available Vivosonic Aurix hardware. To conduct this assessment, parents of infants admitted to the Vanderbilt University Medical Center well-baby nursery were offered enrollment in this validation study at the time of the clinical newborn hearing screening. A research screen consisting of a dry stimulus run and true stimulus run in one of the subject’s ears was completed on 99 participants. Order of tests was randomized, and testing was completed consecutively in the same encounter to control for test environment. The research screening results were then compared to the clinical screening results in a side-by-side examination, and test results were analyzed across parameters to assess system hardware performance, which will be discussed.
- To learn how to initiate the study of equipment validation and its importance for improving newborn hearing screening technology and programs.
- To review the comparison of newer hearing screening hardware performance to older hardware performance both objectively and subjctively in order to analyze utility of new screening hardware/equipment.
- To consider the utility of the newly designed equipment in areas with limited budgets or resources for follow-up testing, including the opportunity for teleaudiology.
