The PROTECT Pregnancy Study was designed to pilot direct-to-patient data collection methods for use in postmarketing surveillance into the foetal effects of maternal medication use in pregnancy. This study which recruited women between October 2012 and January 2014 explored whether women in participating EU countries were willing to provide information via the internet to enable prospective collection of medication exposure data and information about other life style factors during pregnancy. The study's main objective was to assess the extent to which data collected directly from pregnant women via the Internet and an interactive voice response system (IVRS) would provide information on medication use and other potential risk factors throughout pregnancy that is suitable for research purposes.
