Abstract
AimTo explore antidiabetic medicine prescribing to women before, during and after pregnancyin different regions of Europe.MethodsA common protocol was implemented across seven databases in Denmark, Norway, TheNetherlands, Italy (Emilia Romagna/Tuscany), Wales and the rest of the UK. Women with apregnancy starting and ending between 2004 and 2010, (Denmark, 2004-2009; Norway,2005-2010; Emilia Romagna, 2008-2010), which ended in a live or stillbirth, were identified.Prescriptions for antidiabetic medicines issued (UK) or dispensed (non-UK) duringpregnancy and/or the year before or year after pregnancy were identified. Prescribing patternswere compared across databases and over calendar time.Results1,082,673 live/stillbirths were identified. Pregestational insulin prescribing during the yearbefore pregnancy ranged from 0.27%(CI95 0.25-0.30) in Tuscany to 0.45% (CI95 0.43-PLOS ONE | DOI:10.1371/journal.pone.0155737 May 18, 2016 1 / 17a11111OPEN ACCESSCitation: Charlton RA, Klungsøyr K, Neville AJ,Jordan S, Pierini A, de Jong-van den Berg LTW, et al.(2016) Prescribing of Antidiabetic Medicines before,during and after Pregnancy: A Study in SevenEuropean Regions.
