Evaluation of universal newborn hearing screening in Switzerland 2012 and follow-up data for Zurich


Metzger-Müller, D; Pezier, T F; Veraguth, D (2013). Evaluation of universal newborn hearing screening in Switzerland 2012 and follow-up data for Zurich. Swiss Medical Weekly, 143:w13905.

Abstract

BACKGROUND: The European Consensus Statement of Neonatal Hearing recommended universal newborn hearing screening (UNHS) in 1998. UNHS was introduced in Switzerland in 1999 under the auspices of a "Swiss Working Group Hearing Screening in Newborns". The aim of this study was to evaluate the number of newborns being screened and consequently followed-up in Switzerland for the year 2012.

METHODS: Postal questionnaires were sent to all registered maternity clinics and birth-centres in Switzerland. To evaluate follow-up of newborns failing the screening process, a retrospective consecutive cohort analysis of newborns failing screening at the University Hospital Zurich between 2005 and 2010 was performed.

RESULTS: A total of 102/110 (92.7%) maternity clinics and 1/14 (7.1%) birth-centres routinely performed UNHS. When weighted according to the number of births in the varying locations, 97.9% of all newborn received hearing screening. At the University Hospital of Zurich, 253/12,080 (2.1%) newborns failed the screening test and in 15/253 (6%) a relevant bilateral hearing impairment was found. This makes an overall incidence of congenitally relevant hearing loss of 0.12%. Unfortunately, 33/253 (13%) of newborns with failed screening were lost to follow-up.

CONCLUSION: UNHS is well-established in Switzerland and the vast majority of newborns are screened. However, follow-up of failed screens is disappointing. Further measures need to be taken to improve follow up.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
