[Universal newborn hearing screening : Definition of uniform parameters by the Association of German Hearing Screening Centers as a requirement for nationwide evaluation with valid results].

Background: Since 2009, all newborns in Germany have been entitled to universal neonatal hearing screening (UNHS). UNHS with tracking of test results leads to earlier detection of hearing disorders. The Association of German Hearing Screening Centers (Verband Deutscher Hörscreening-Zentralen, VDHZ) was founded to promote nationwide tracking, validity and quality control of UNHS results.
