Although more and more hospitals are implementing universal newborn hearing screening programs, there is still very little information available about the costs of newborn hearing screening programs. The few articles which have been published evaluate technologies or protocols which are no longer used, are incomplete, or are based on hypothetical estimates of the costs and time necessary to do screening. After briefly reviewing the extant literature, this article describes a cost analysis of a TEOAE-based universal newborn hearing screening program. Reasons why the cost per baby ($7.42) is lower than in previous reports are explained, and the benefits of having accurate cost analysis data are summarized.
