Data collection
Data including the consultation and follow-up survey was self-reported
into the WoW website. Data was transported to an Excel file and
anonymized. Follow-up surveys were sent via e-mail five weeks after the
shipment of medication. If needed, a reminder was sent after another two
weeks. Similar to follow-up instruments in clinical settings, the survey
consisted of 30 questions which included information on completed
treatment, how the pregnancy was confirmed, perceived side-effects, any
visits or contacts for medical care, any treatment received, how
information was accessed and emotions after the procedure. Although WoW
has been active since 2006, we included data from the year 2009 onwards
as this was the year WoW changed its data collection system.
