Pulse oximetry screening for congenital heart defects in Switzerland: most but not all maternity units screen their neonate


Kuelling, B; Arlettaz, R; Bauersfeld, U; Balmer, C (2009). Pulse oximetry screening for congenital heart defects in Switzerland: most but not all maternity units screen their neonate. Swiss Medical Weekly, 139(47-48):699-704.

Abstract

QUESTIONS: In Switzerland, the screening of neonates for congenital heart defects (CHD) by using pulse oximetry (PO) on the first day of life was recommended in 2005. We assessed the current practice of Swiss maternity units regarding PO screening to define the actual screening rate in Switzerland and to detect possible difficulties in the implementation of this screening. METHODS: This descriptive study was conducted by means of a standardized questionnaire that was sent to all Swiss maternity units. RESULTS: The response rate was 100%. 76% of the units perform regular PO screening and, on the basis of the number of births for 2007, this means that 85% of newborns in Switzerland undergo screening. Although units which do not perform PO screening include every category of maternity unit, the screening is performed to a significantly lower extent in birthing centres than in hospitals (p <0.001). The number of unscreened neonates was 5398 within small units (<1000 births per year) while it was 6137 within large units (>1000 births per year). The main reasons for not performing PO screening are financial factors and the belief that clinical signs are sufficient for the detection of CHD. CONCLUSIONS: Greater effort is needed to implement a nationwide PO screening program for CHD. Special attention should be paid to birthing centres given their limited capacity to treat newborns with critical CHD.

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.
