Does an educational video for aneuploidy screening improve informed choice among pregnant women? A randomised controlled trial.

Background: Poor knowledge and the lack of deliberation have been cited as reasons for women making uninformed choices about aneuploidy screening. Adequate pre-test counselling is of particular importance where non-invasive prenatal screening (NIPS) is being increasingly offered as a primary screening test.

Design: Women attending the antenatal clinic with a singleton pregnancy below 14 weeks were randomised to receive routine counselling or the intervention-a 16-min educational video on aneuploidy screening before their consult.
