PROTECT Pregnancy Study: An Exploratory Study of Self-reported Medication Use in Pregnant Women

IMI PROTECT - Work Package 4 - Pregnancy Study: An Exploratory Study of Self-reported Medication Use in Pregnant Women

Study was a non-interventional, prospective study of pregnant women who agreed to provide information about their medication use and certain lifestyle factors on a periodic basis throughout their pregnancy. Volunteers were recruited by measures such as placement of pamphlets near pregnancy test kits in pharmacies and by links from carefully selected websites and social networking sites. Subjects were invited to learn about the study either through visiting the study web site or phoning a telephone number where a recorded message described the study and invite eligible women to register for participation.

Participants were asked whether they prefer to provide data via the internet or by interactive voice response system (IVRS).

Data were collected in the predominant natural languages of the four study countries: Denmark, the Netherlands, Poland, and the United Kingdom (UK).

Data were collected on use of prescription and non-prescription medication, as well as on use of herbals and homeopathic medications. More information was be collected from women who provided their response over the internet than by phone, in order to best utilize the full capacity of internet- based data collection.

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.

Pregnant women were recruited for the study using a variety of methods and were asked about use of medications, alcohol and tobacco, recreational drugs, herbals and other factors that could negatively affect birth outcome. The pilot study revealed that women would indeed volunteer to provide information on medication and lifestyle factors during pregnancy, with 2521 women enrolling from four countries over 8-18 months. The four countries include the United Kingdom (UK), The Netherlands (NL), Denmark (DK) and Poland (PL). Of those who enrolled in the PROTECT pregnancy study, only 2066 provided any data, with all but one providing data via internet.
